Here are some pictures of the Lego enclosure: https://www.reddit.com/r/espresso/comments/owpfe7/i_made_a_lego_enclosure_for_rex_c100_pid/. I have a question on the pid, it is normal for the brew light to blink (off and) while it stabilizes to the target temperature. Ive been hearing the solenoid valve click several times while on steam mode as well, and the group head releasing steam on occasions, which also make me worry in terms of the wiring, or the parts just need replacement. The 103 is not a true 103, that is what is getting measured in the boiler wall, and there is also a temperature drop off between the boiler and the portafilter, so your final espresso temperature will be lower. Hi David. The .ino file includes several libraries. Just use a multimeter to find the switched mains, and you should be able to follow the thermostat wires. You could simulate pre infusion by briefly running the pump. You can only buy them as spare parts. 1. Is it necessary to use a heat sink with the SSR installation? However I now need to connect steaming and brewing circuits in parallel rather than serial because steaming circuit will not be closed unless I turn on steaming switch and supply power to steaming SSR. You would need to put the boiler heater element between the controller terminals 2 and 3. Im sorry about that, Eric. Although this is optional, it is difficult to access the power switch to tap power for the PID, and it is almost impossible to reach the thermostat without moving the boiler, and the boiler cant be moved unless the steam wand is removed.

Perfect, came back here to ask this question! Because there is very little information on how to install a PID on the latest generation of the New Classic (2018 and newer, also called the Gaggia Classic Pro in North America), here are instructions on to do this. Any ideas? 2. I hope it helps some EU folks not spending extra hours on debugging this minor EU-US model difference . By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. Print services. PID, Auto Shot Timer Add to Watch list. Adding a PID on and replacing the OPV spring will help for sure, but by that point if you buy the PID as a kit from Auber or Shades that's $200 and the OPV spring from Shades is another $15. If the wiring was done correctly, the PID should power up when the Classic is turned on. The SSR is just a fancy switch and it should only be turning on and off, so depending on how you measure you may not see current. The thermocouple should be snug but not too tight as the threads are not super robust. Thank you Chris for the awesome write up. It appears to be from 1998 and is barely used. The LED on the SSR is functioning but no current can be seen. (To be certain, the M4 is the correct one). Hey Chris, Im wanting to put the pid into an extended 3d printed driptray. But Ive downloaded the wiring diagram for my machine. They are not polarized so you can connect either one to either terminal of the SSR. Hi Chris, i noticed you used the K type thermocouple with the M4. Please let us know if theres a way to show our gratitude if theres a charity or cause we can donate to for you putting this guide together. And this is the thermometer out the back. For espresso, 9 bars is the generally preferred pressure. I bought the PiD from Amazon referenced in a comment above and its working fine. Or do you think the same set will work with QB-T7100? My ECM Giotto "Phoenix" Restored by the Coffee Machinist in Melbourne, Australia. If youre following a recipe that calls for a specific water temperature, then it would be easier to do this with an offset at the PID. Thanks for putting it together, this has helped me a lot in figuring out most of my doubts with a PID project for a Gaggia. Net Weight: about 150g Hi Andrue. Consult the instructions that came with your PID to make sure. Is 103 degree Celsius the best target temperature fit the PID? $16.95. Gaggia Classic & Classic Pro scales housing (BOM and models) Base Functionality Housings. Just leave the SSR disconnected, or dont install it at all. You will be working with potentially lethal mains voltages. Thanks! Thermocouple included: M6*1 thread , K type , 2m cable Mains is house current. Do not work with the Classic plugged in. This will be the one at the bottom of the boiler, closest to the group head. Hello Chris, $399.00 + $19.99 . When I got my C100 the thermocouple was M6, i ended up buying an m4 brass bolt drilling it out, and inserting the thermo with some glue and heatshrink on it and it works like magic added some thermal paste. Left or right side if facing the front of the machine? This is the setup that I have assembled two days ago. Thanks Jimmy. If nothing happens, download GitHub Desktop and try again. (Video) PID on Gaggia Classic Pro - Game changer to budget espresso brewing at home Here are the installation steps: Unplug the Gaggia Classic. Curtis LMWDP #551 "Taste every shot before adding milk!" Henry_k #5 : by Henry_k February 10th, 2021, 12:35 pm I see no advantage of controling steam temp by PID - if it is 145C or 140C - not a big deal. Or buy a machine with a built-in PID. The C-100 can accommodate only one sensor/SSR, so you would only set it for brew temperature. Keep the thermostat, in case you want to return the Classic back to factory condition. Hi Peter. I still have one question you may be able to answer. You should be able to find the switched mains with the help of a multimeter. I would be surprised if your water is 80 degrees coming out of the boiler with the PID set to 103, but its possible, depending on the thermocouple youre using. Does the wiring youve supplied automatically shut the PID unit off when you engage the steam switch? + $55.24 shipping. I think Mr Shades has managed to do this using only cables because I dont think he instructs anything to void the warranty. Thats an awesome enclosure. Hello Chris, Use the other probe to check the other two wires coming from the power socket. Note that according to this video: https://www.youtube.com/watch?v=UETVv0qgz-w, you can switch the C-100 between Celsius and Fahrenheit. Awesome PID installation guide! If you really want these features, its probably time to think about upgrading your machine. Remove the top of the machine and locate the boiler thermal switch. Connect the +/- leads from the PID to the SSR input terminals, paying attention to the polarity as these are DC. The PID is really converting the mains voltage to 12VDC both for its internal operation and to drive the SSR, so the PIDs draw is quite small. Hi David. PID example MAX31865 driver is finished. I stumbled onto this before I actually had my Gaggia in hand and went about ordering all the parts. There is no 12v anywhere in the GCP, its all mains power inside. What exactly is a mains-rated wire, and where would I find one? The connector is on the back of the machine, where mains power is tapped with a piggyback connector and goes to the PID. I print with PLA filament, which has a much lower melting temperature than the plastic that Lego uses. I have changed the default value of the SL parameter to work with the RTD sensor (K thermocouple was default). I found that moving the boiler up and to the side allowed me to get to the thermostat from the bottom really easily vs. the top. Terrific write-up thank you for posting it! Do you know how to do this? The boiler in the Gaggia can get hot enough to melt non-silicone insulation so if you don't have silicone wiring, make sure to keep any wiring well clear of the boiler. Hi Chris, I like the quality of the shots, and temperature consistency is more important to me than pressure consistency. However I dont know if my unit is properly calibrated and/or has a proper offset. Pressure control could be super nice to have. Not sure why that was the case. PWM dimmer for preinfusion Water tank lid custom made for Gaggia Classic pre 2018 model stainless steel. Chris, do you recall what size flat head screw was used on the 3d printed box for the REX-100? If you can share a picture of it, or a link, I can add it to the article. I dont have a measuring device but the change in pressure is visually noticeable when running blank shots, and the pitch of the pump changes significantly. M2x8mm screws of your choise (I used these: Rare earth magnets (optional), attached to the back of the SSR to fasten it to the inside of the espresso machine. Set the cover and screws aside. Hi guys! Then use the left/right buttons to select the digits to increase and decrease, and the up/down buttons to change the digits. Its actually reading too high.. 98 deg against 92deg measured by both my oven thermometers. Thank you for making it. Connect one meter probe to ground (the GC chassis should always be grounded, otherwise connect to the green wire coming from the power socket at the back). The documentation showed the default settings as P:30 I:240 D:60, but after tuning they were P:37 I:50 D:12. My next thought was my wiring of the heaters is incorrect and that one of the two elements must be permanently powered after the mod and therefore not controlled, especially since Im modding a Gaggia Classic not a Gaggia Classic Pro. Their kit is convenient, and is the way to go if someone doesnt feel ready to take on a 100% DIY project. Finally got around to upgrading my gaggia pro to having a PID! Run the TC leads out through the back of the machine and into the PID, attaching to the MCP9600. Either way, you are looking at a lot more complexity and cost. It just overrides the PID and heats up the boiler to the factory preset steaming temperature.Links to parts [None are affiliate links]https://bit.ly/3gL9c95 - XMT 7100 PID unithttps://bit.ly/3xgAHhc - PT100 precision temperature sensorhttps://bit.ly/3wnZD6l - Fotek solid state relay 25Amphttps://amzn.to/3xamPFg - cable sleeve (different widths available)https://amzn.to/2RSAge0 - magnetic tape (example link, different widths available)https://www.thingiverse.com/thing:3671244 - 3D printed case file (print this locally)https://bit.ly/3pPphP0 - the unattractive aluminium enclosure if you wish to go that routeYou will also need:1. . You need a 85-250V DC model, as the power will be coming from the Classic, which is mains-level voltage. Remove this thermal switch and replace it with the M4 thermocouple, making sure to add thermal compound if necessary. Leave this cable longer than needed for now, it will be trimmed and terminated later. Ill dismantle on a cleaning weekend and test the thermocouple again. A cheap multimeter is all you need. There's a circuit diagram included in the repo. Thank you very much if you find the time to answer me . Realized with your last comment you dont have the offset in place, my bad. I have to mention that coffee taste is good, not harsh or bitter. This is sold on amazon Once these bolts are removed, the boiler can be moved around without having to disconnect any hoses or wires. You effectively would have two steam modes, one PID-controlled that replaces the brew mode, and one classic thermostat-controlled steam mode. The C100 is probably made by dozens of different manufacturers. The image I used is wrong and confusing, and I have now updated it. 40A SSR Solid state relay included I managed to succeed on brewing side with DA SSR however I could not find an appropriate diagramm for adding my AA SSR for steaming alarm function. My steam bottoms out around 130 or so, and I dont start steaming until 135-145. Before replacing the thermostat, maybe check whether your PID and thermocouple are calibrated, before committing to buying more parts. Yes it is normal for the brew light to blink like this after you install a PID. I have installed the supply cable for PID unit using piggyback spade connectors. By the way there are three options as 12V, 24V and 85-250V DC. Depending on the draw of the display (I saw 50mA somewhere), you could also try running it off a battery. The coffee water temperature in the boiler of a home espresso machine is originally controlled by a bi-metal thermostat, which causes a big temperature swing. If you really want to avoid the heating element switching while youre pulling a shot, you can blip the steam switch for a few seconds before brewing and that will bring the boiler temperature up a few degrees. Watching the steam temp with the PID is interesting (I know it has no effect on it, but it is cool to see how it reacts now) and it is definitely best practice to steam while its on its way up in temp, once it hits the set point it comes down for a while (mine settled around 130 before it started back up). The biggest problem was the fact that the brew water control did not work: the SSR was never switched on by the thermocouple output. Both shades and auber use the alarm 1 & 2 though with different PIDs for steam with upper limit & lower limit. (PID Temperature Controller Meter Indicator, Jaybva Digital Universal Thermostat C and Fahrenhe F Display SSR and Alarm Output 40A Solid State Relay and Thermocouple Probe Heat Sink Included)? Hi Chris Showing all 6 results. Gaggia Classic Coffeemaker Coffee Drink Food and Drink comments sorted by Best Top New Controversial Q&A Add a Comment More posts you may like. There are other resources online as well. Even though the wires are insulated, as someone posted earlier, that metal is sharp and the vibration from the machine may eventually cause the insulation to fail and then your whole machine is a conductor. Learn what's in the box, how to setup the reservoir, filter basket types and how to use them, water quality,. For those interested I just bought a cheap ($13) K-type thermocouple and thermometer (TM-902C) https://www.ebay.com.au/itm/224710871179. This would explain the constant switching on and off. If the PID stays on when wired directly to mains power, you will need to figure out which power wire to tap into. I figured a video about this could be of interest to you, so here's the link:https://youtu.be/ZAtsuS6B6xg. i heard from some that the PT100 with the M4 is more accurate. If youre not comfortable installing this yourself, and taking on any followup maintenance, I think you would be much better off purchasing a machine that comes with a PID from the factory. Thanks in advance, this was a huge help! Since I cant control that, if you want to use it, you will have to parse the data: each line, after the headings, should start with the PID parameter (P, I, D) followed by the reaction of the controller. Inside the GC, all bets are off as to wire colors, aside from green for ground, and even then, I wouldnt assume anything. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. Complete with dual 250W cartridge heating elements (up to temp in ~8mins), bead-blasted stainless steel and internally a hammertone blue powder coat. The PID gives you consistency. Thanks for your time. Thanks in advance for any reply! 39. r/espresso 24 days ago. Hi Miguel. under the name replacement PID kit parts with very low prices. Remove the cover assembly and filler funnel by unscrewing the two small screws at the rear of the top. Auto-tuning PID cooling/heating control This process involves working with potentially lethal mains-level voltages. Tags Slim PID Holder for Gaggia Classic Design to 3D. Cross referencing with the with the manual confirmed that the stickers had been reversed. ESP32-WROOM32 - ESP32DEVKIT1; 40 A SSR . For the sake of piece of mind, I have ordered last night a K type thermocouple in order to replace the RTD P100 and close the open loop in my head about PID type and sensor. About 60cm of 1mm2 (17AWG) cable to deliver power from the Gaggia to the PID 3. It seems the wiring varies even within model years, and between model regions. The same complexity applies to pressure control. . Thanks heaps for the detailed instructions. But it will require some dismantling of the work you have done. Autotuning had resulted in shot instability up to 10 degrees during a shot probably because conditions during standby and during brewing are very different than each other. To set the target temperature, press the 'Set' button on the front of the panel. Thanks. I have found the exact PID unit which Mr Shades is using and purchased it beside the Rex C100 kit you mentioned above: What you describe is pretty normal, except that I am a bit surprised that your steam drops temperature down to 102. Marca: Gaggia: Capacidad: 72 Onzas: Color: Acero inoxidable cepillado: Dimensiones del producto: Chris thank you so much. I am glad you got your setup working Murat. Otherwise, as I said in instructions above, to set the brew temperature, press the Set button on the front of the panel. This PID-SSR combination does away with the 12v connection, and uses three wires for the mains power and SSR, with one wire shared between mains and the SSR output. The fun of the PID is not just the great stability, but the ability to fine tune the brew temperature to your taste! Basically, instead of running the pump for a few seconds and then shutting it off (which dumps your pressure courtesy of the solenoid valve) you open the steam valve about 1/4 to half way, hit the brew switch and then slowly close the steam valve (about 5 seconds or so). Some shops are quoting $80.00 for the PID enclosure + lid. If you have never done this before, know that you are working with live household current, and this can kill you. I am guessing that its caused by the current draw of the boiler heater. There is definitely a falloff from the temperature reported by the thermocouple at the boiler and what you will measure at the group head. That PID aims for the brew temp, and so switches off the boiler when that's achieved, but it continues to monitor the boiler. Guys, there is mains voltage here. I will monitor it over the next few days, but if the coffee takes good, and the only thing I notice is the warmer cup tray, Ill be fine with that, better in fact! When I turn off, it goes back to zero. Looking forward getting your thoughts and ideas The steam mode drops to 102 before the power cycle kicks back in, with the valve open or closed. How to install a PID on a Gaggia Classic Pro - DIY, cheap and good looking! Gaggia Classic'teki stma sistemi basit mekanik termostatla altndan scaklk 85-105 derece arasnda gidip geliyor ve siz demlemenin hangi scaklkta balayp hangi scaklkta bittiini bilemiyorsunuz. Hi all, I recently bought a Gaggia Milady secondhand. Should this be cause for concern, maybe caused by an error in wiring the PID? Remove the thermostat. My only concern is that Mr Shades has two types of SSR units 40AA and 40DA. Replacing that wire= everything works perfectly now! When set up on my bench it tucks away nicely in behind out of sight and only needs to come out when in use. Hey Chris, Pull the cover assembly off by pulling upwards, and disconnect the ground cables. robert kujawa 348 subscribers Subscribe 85K views 1 year ago In this video I'll install a PID unit on my. In it's current revision, the Arduino board is still powered via USB so there needs to be an opening to plug in the USB cable. Wear a glove when reaching in from below, otherwise bloodletting is likely. Hi Chris, I am gathering / ordering the parts specified and was surprised to find out the price for 3d printing price spiked. Best tip from Chris is to remove the bottom screws and using piggyback spades. I have read reports of measurements of up to 8 degrees C lower at the portafilter. Im wondering if this could somehow be the outcome of a bad SSR: Im not seeing current flow between the two AC terminals of the SSR when the PID is attempting to heat the boiler to the Set Temp. Do the same with the other connector wire. PID interface for the Gaggia Classic Pro. The MCP9600 board is fastened with a screw to the small ledge inside the 3D printed box. Double sided tape will work. Required fields are marked *. To be clear, a PID can increases the likelihood of a consistent starting temperature. Maybe this will help? It should be the power/mains line that comes out of the main power switch, but before the boiler. Apart from that, when I turn on steam mode, the thermostat takes temperature in the machine around 151c-152c, it doesnt turn on again after it goes down to 102C, then turns on and repeats the cycle. Close the PID enclosure, and attach it to the side of the Classic. One last question: Auber and Mr Shades are calling their sensors PT100 while mine is K type thermocouple. https://photos.app.goo.gl/8yPwJcEPDi1c5tfY7 It will also be completely reversible and much cheaper than ready made solutions!This clip can also be treated as a how-to instructional video for anyone wishing to go the DIY way. And anything is going to be a huge improvement over the thermostat that the PID replaces. As for your PID always remaining on, it looks like you wired it to the unswitched mains, instead of the switched power. I think this would be the most important parameter of the build, obtaining the correct temp of the water. For me I start steaming when the boiler temperature reads 130 degrees C. So for others who are contemplating going for the extra effort of installing the steam PID, know that the return on investment of doing this is questionable, if not net negative. It also means that you can only see the temperature and access the PID buttons from the top. On and off oven thermometers instructions that came with your last comment you have!
