@lansky Can you review the above posts and ID's, and edit the information? We will need to know if/what tickets were fixed with replaced thermistors and which ones are having issues after replacing thermistors.
@karrad Yeah, mostly Aero and he has like 2 V3s. We went over tightening the thermistor connections and have not heard back yet what the results were.
@lansky You said 5/7 tool heads, are these all aerostruders and v3s? Have you checked thermistors on them yet?
@karrad We have not tried going back to 21.08 yet. What firmware version would you want to use? Since 21.08 does not have setups for the V3 or Aero we would have to choose a custom firmware version to flash. Would 21.08 even work for the V3 extruders?
Cura 2.6.69, Mini Aerostruder. He was having heating errors, after lowering the fan it's no longer an error but the temperature does drop and stay lowered when the fan turns on.
Cura 2.6.69 with that firmware, V3 on a Taz 6. He does not get a thermal error but his right hand side extruder is consistently lower then the left hand extruder.
Cura 2.6.69, firmware 220.127.116.11, V3 on Taz 6. Nor maintaining temperature.
@lansky Does reverting to 21.08 and included FW fix the thermal issues seen above?
Cura 2.6.69, flashed firmware from that Cura version, V3 and Aero, customer has multiple toolheads and said that this happened on 5/7 of his toolheads. Thermal errors.
Cura 2.6.69, flashed firmware from that Cura version, V3. Thermal runaway/failure to heat while setting up extruder (using the Polylite/Polydissolve profile)
Printing using Octoprint. Reproduced at different layers.

Thermal Runaway E0 when fan turns on, using the standard profile in latest version of Cura for Bridge Nylon. Lowering the fan speed helps, but does not solve.
Was able to print okay Friday, but had the same issue this morning.

Heating failed E1 roughly 10 minutes into the print of impossible gears. Double checking that he has latest version of Cura and firmware.

I just set up an RMA for a customer getting the same error. He has Cura 2.6.69 with the latest firmware installed.

157915 Customer reports V3 Dual Extruder for TAZ 6 is sending Heating Failed E1 error. Will have him update Cura and check thermistor crimping.

157801 Heater Failed E1 error on V3 Dual Tool Head.
@lansky Thanks for the update. From now on, please log any of the thermal error issues you have on this ticket. It will help us keep an eye on them opposed to the spread sheet.
Here is the message without the link to shared-j: "After going through the RMAs for both the V3 dual extruders and Aerostruders each RMA has been a thermistor replacement/hotend replacement. There was one where we found the fan was not turning correctly."
From the look of the guys screenshots his temp is very crazy mimicking @benmalouf s printer before
I'll go through the RMAs listed in the tracking sheet and see what the results were. Off the top of my head so far it has been thermistor replacements.
This was being caused by a short in the LCD ribbon cable that was causing Marlin to think the KILL push-button on the LCD was being activated. On the TAZ, this button is inaccessible.
It looks like Marlin kills the printer when it sees a M112 command in the serial stream. Since this is not happening in earlier versions of Cura, I suspect something changed for this command to be issued.

@west it is possible that it is the same issue we saw with Aerostruders, but we would like to verify.
@karrad I dont think aeorosturduer PID will work since the aero uses v6 heater block and the dual uses the some(sum?)struder block
@FitzNYC Thank you for the report. We have opened T1624 to look into this. Please feel free to add yourself as a subscriber there for updates. In the mean time, can you reach out email@example.com they may have a couple hardware items to look into.
@marcio Please disregard, we have yet to implement the Auto Eeprom update in 3.2.x
@marcio Should this be included on Hibiscus as well? I am showing different numbers while on 18.104.22.168 FW:
Hibiscus 3 is having the same problem, and it doesn't matter what STL I use.

Marlin 22.214.171.124 has the new PIDs.

I am having the same issue and upgraded to 126.96.36.199 and now it fails immediately when heating. I have a Lulzbot Taz 6 with the v3 dual nozzle. Raspberry Pi is BCM2708, 0010.

Ran several more prints with 188.8.131.52, have had no occurrences of G29 exiting like it did under 1.1.5. Closing this as resolved by 184.108.40.206; if it does pop up again I will reopen.

@marcio Looks like sleep settings killed the print:
Tue, Feb 6
@marcio - I have run (19) prints with a 220.127.116.11 build. No problems to report (with G29 or anything else). Will keep watching for a while, since the G29 issue was so intermittent, but it looks good so far.

Could you see whether you can reproduce this with 18.104.22.168?
