thanks for the great content. im trying to figure out if its worth doing the gagguino or this. might do the gagguino just because hunting down all these cables is hard for a noob like me. anyone here have any links where they bought theirs recently?
I'm not familiar with other machines, but the principle should be applicable. All we're doing here is replace the thermostat with a more intelligent controller. I imagine a number of machines could benefit from this upgrade.
Hi Robert thanks for the video. Didn’t want to spend too much on a machine so I got a classic, but a pid set is 220€ now so I followed your list and orderes the parts from aliexpress, here in May, hope everything goes well (I have the new 2023 machine)
Great tutorial. The only thing I do not understand is - the temp sensor PT100 that you screwed in the boiler and put thermal paste - isn't this paste in contact with the water? Why do you need thermal paste, or the hole does not go in the boiler and is just in the wall of the boiler?
Hi robert! Looking forward to doing to this to my gaggia, although i cannot find these wires anywhere or what they would officially be called in my local home hardware SiHF 2x0,5mm2, FLRY 1.5mm2. I am canadian if that makes a difference
Just observe the diameters and temperature resistance. These are 2x0.5mm2 and 1.5mm2 in diameter. I went with fancy silicone wires, but you can pick those dedicated for automotive engine bay wiring. They will be able to withstand high temperatures around the boiler.
First of all, thank you for the great video and the effort you have put into this. Regarding the control parameters of the PID, these are generally too conservative due to the autotune process and therefore the intrashot differences are very large. I have found the following setup to be optimized: P=1.6; I=10; D=3 runs stable and fast for me.
Hi! I followed this as closely to what was in screen and it seems to work... Pid turns on and starts tuning the temp. But it trips the breaker of the house as soon as I hit the brew switch (I have the dimmer mod installed). Anyone has a guess as to what's happening?
Thank you so much for this "how to". I did this PID mod with single SSR ( Brew temp only ). I have question, is it safe to use the steam switch? Does the steam temperature has its maximum to stop heating? Because we cannot control the max steam temperature on the PID with single SSR. What happen if i swtich on the steam but did not use the steam? Will the boiler gets broken? Or it will just stop heating the boiler at certain temperature?
Great video - thank you! How important is using a thicker cable for the PID power connection? I have an 18 AWG silicone insulated cable at hand, but was wondering if this may be too thin. Thanks
Scrolled through a lot of comments, seems it works, there's just the difference where to get the power from.. still scrolling to find other users solution for it. Many thanks for you video, did get me going...!
@@obBi0 that's correct, it works with the previous version, but you need to tap into power in a different spot. The exact details are in the comments, I hope you can find it.
Wait when you said this machine uses 220v, does that mean the NA version transforms 120v from the outlet into 220v and hence NA version can use the same pid?
I done this upgrade on my gaggia and honestly was one of the best things I ever done. All you need is time and some tools, another very important tip is to change the steam arm to single hole for insane results.
Thank you for this amazing tutorial, I have only one question, which way did you connect the Ground and VCC to the PID, or perhaps it doesn't matter because its DC? Thanks anyways
Thanks to you i was able to do this install about an year ago, however as of recently my XMT7100 PID just stopped powering on. Light on the Gaggia power button turns on, no heat, and i can't tell if the PID or Relay are getting any power. Any troubleshooting steps you recommend? I checked all the cables and connections, they seem fine. I have a multimeter if it'd be useful, but I'm not familiar with how to use it (it's an AstroAI Multimeter 2000), thank you so much for your help.
Hi Mr Robert, Good job and thanks for sharing the installation process of PID kit for Gaggia Classic Pro First of all I have to say sorry I have 3 questions as I very new to this kind of coffee machine, please help and guide me and Thanks in Advance I bought this model: GAGGIA MILANO CLASSIC RI9480/13 (2019 Model - SIN035UR) and to arrange all modification parts and wires from Ali-express and other parts from different places it took me almost 2 months in the mean while I have watched your videos many times to understand myself and I have prepare a notes and bought necessary parts and kept ready in hand to install PID I would like to Replace or Mod the Rocker switch from Monostable to Bistable to take advantage of using wifi switch to keep my coffee machine ready to use during busy day , even after changing the switch the wiring will PID installation will remain same as {How to install a PID on a Gaggia Classic Pro - DIY, cheap and good looking!} explained in the video or if there are any change please mention I would like to install 2nd SSR to the Steam function as well, do I have to use 25AMP DA or 40 AMP DA? Please help in this process for wiring and connections ( video would be more helpful for me and I appreciate if you could spare time for this one as well ) or at least a diagram and parts list I have XMT7100 1/32 DIN model I will Modify the PID to use for 2nd SSR as as you suggested “ Mr. Damian Witonski ” video to modification Please make a video for the PID temperature settings for both the Brew and Steam Thanking You Tej with Love from INDIA
Hey Mr Robert i have found the PID temp settings in the comments section and understood you have skipped steam PID temp , can you help for wiring changes if i want to change rocker switch bistable
Amazing video! Very detailed and easily understandable, with great camera angles. I happened to buy a used ascaso dream (thermocoil) for a very affordable price that i had to buy it as my first espresso machine. I have enjoyed the taste of the shots, but there is room for improvement. For now i am satisfied with other accessory improvements, but I am really curious about installing a PID into it. I found out that couple of people have actually done this mod for this machine, but there ain't any detailed information or guides for this. I wonder how much would the installing differ from this great example of yours.
Hi there, two questions if you don’t mind. Firstly, why do we need to swap the factory installed temperature sensor for that PT100? Secondly, is it possible to build PID for GC on other than XMT7100 controller? For example on such as PID Gicar MC740 which seems to be dedicated to Lelit coffee machines. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-BJLocPnniM8.html&ab_channel=Lelitinsider
The temperature sensor that comes with the machine is a thermostat with a significant degree of latency. It's way too erratic and slow to react for the PID to function, plus the PID cannot read the temperature through the thermostat. This is why you need that pt100 sensor. As for kits from other machines: they might work, but they can also be a chore to set up. I'm not competent to say if the lelit kit is gonna work, sorry about that.
This is very helpful and gives me confidence to attempt PID mod.. it’s a shame Gaggia do not integrate a similar solution even if it meant producing a variant model for aficionados, they could then call this model the “Pro” version!
When mentioning that your unit runs at 220 volts and that's what you need to power the PID, would I be okay following the same instructions for my unit, which runs on 230? The PID itself is rated 85~260VAC/50~60Hz
The printed case is way nicer but printed locally it seems to cost over $60, more than all the other materials put together, many times what the aluminum case costs.
@@robertkujawa3504 ohhhhh!!!! Ok thank you so much!!!! I'm going to adapt this install on a different machine I have! Thanks so much for putting all this info out here :)
