Diagnose the E3D REVO - Prusa Thermal Management error

- E3D REVO stopped working for many people. This video shows my exact situation, which seems to be the same situation many others are in with the REVO hotend on a Prusa MK3 printer.

I just concluded 3 or 4 days working with E3D. Same guy as listed in the email, as a matter of fact. The problem still persists today. E3D will have you checking everything until you reiterate the fact that your printer worked fine with the 3.11 firmware. Then they step back. Looks as though they can't fix it. I bought a PRUSA EDITION REVO SIX Hot end, that doesn't work well with Prusa. And as far as the faulty heater core goes: how does it fix itself with a firmware change? Magic? This is SAD !!
Hi, Had the same issue after upgrading to the REVO Six yesterday on the MK3S+. Here is what I did to get it working
Connect your printer to your PC via Pronterface. In the interface start sending the following commands:
1. Send M503 to show current settings
2. Send M310 S0 to temporary disable Thermal Management for PID cal
3. Got to LCD -> Calibration -> PID cal.
4. M310 S1 to enable Thermal Management
5. Wait until the printer is cold before you continue.
6. Send `G28 W" to home all without mesh bed level
7. Send G1 X125 Y105 Z1 to move the hotend to the middle of the bed
8. Send M155 S1 C3 to auto report temps and fans
9. Send M310 P40 U-0.0014 V1.05 D0.15 L270 to set REVO values
10. Send D70 S1 to enable tml debug code
11. Send M310 A F0 to run Thermal model cal. without checking existing Thermal Management settings
12. Send M500 to store TM values
It should all run smoothly. After, disconnect the printer and run first the Thermal Management calibration then the PID ( letting it cool between calibrations). You should be good to go after. But really, this was not a cheap kit, they know of this issue, and I hope someone in the software department was fired.
I did it and it works, thank you!
@@stephanevarin6938 glad it worked for you, its a simple issue to resolve once you figure out that its the TM panicking and protecting the printer because its heating up at a different rate. There is no excuse for E3D to not have had it sorted by now.
Sadly it did not work for me, done it now multiple times and every time I get a thermal error after a while and neither the PID or Thermal Model Cal. do run to completion after I have calibrated both sucessfuly with your provided G-Codes... (but thanks anyway) i will also now write on the Github Issue cant use my printer since I updated and I really don't want to go back because of the MMU2S changes, least they are really good and revived my MMU for me...
thinking about switching to and BambuLab printer...
@@PatteKi Interesting. Question: did you first flash the E3D firmware to the printer? Did it complete successfully (does the model on the printer display have a "R" after the printer model? The G-code should work if the E3D firmware is already flashed...
@@n.neves1776 I flashed the 3.13.3 Revo hex file from the official PrusaGitHub Repo, and on startup the printer displays " Prusa i3 MK3S-R OK"
E3D will be sending me a replacement HeaterCore to install and test. I hope to do it on video, maybe as a livestream. Comment back if that's interesting.
I have exactly the same problem on my Prusa MK3S, I've just installed the Revo and it doesn't work.
Hi. Did it work with the new heatercore?
