Revo 6 not reaching PLA temps
I have purchased a used MK3.5s+ with a Revo 6 Rapid Change hot end. I am running 3.11.0 firmware and am aware of the issues with the Revo and newer firmware.
In the process of running print tests I began to see erratic temperature fluctuations on Octoprint. Soon after that I was loading filament and was not able to get the PLA loaded because the pre-heat will not get the nozzle temp above 190 sometimes 200.
Based on reading and searches I am suspecting the thermistor.
1. Is my suspicion reasonable?
2. Can I test the thermistor?
3. Can the thermistor on a Revo 6 be replaced?
4. Can I use the Prusa thermistor on the Revo 6?
Thanks for your advice!
RE: Revo 6 not reaching PLA temps
the REvo thermistor is an integral part of the revo ceramic heater.
I suggest you reach out to e3D-online.com, and ask for help.

Thank you.

Agreed, the thermistor is integral so if it is not reading it, buy a new Revo heater core. I'm running the Revo on my MK3.5 and it is working great. Only issue (and Prusa acknowledged a fix in the next firmware) is that the Revo won't pass the initial extruder heater test but you can continue and still use the printer with the warning. Works fine otherwise.

- Do you have an MMU connected ?
I say this because I have, and I noticed that the huge serial protocol between the MK3S and the MMU completely screw up the REVO PID and Profile setup.
I had to disable the MMU, setup the REVO, and then enable again the MMU.
Since I ordered the MK3.5 upgrade, and I have a REVO that around 60° raise a THERMAL ANOMALY (but then it worked normally), I ordered a new REVO 60W heather core, so I hope to have more melted material to satisfy the speed once I will have the MK3.5 board.
However I am wondering if the black power supply of the MK3S is able to power correctly the bed, the new Buddy STM32, the MMU3, and a 60W heather... 🤔
RE: Revo 6 not reaching PLA temps
I did the 3.5 upgrade from a stock MK3S+ and accidentally reversed the hotend fan and the part cooling fan wires. The hotend self-test failed, only getting up to 178 degrees instead of 180 degrees in the 3 minute test. Not sure if the Revo has this same issue.
