PID auto tune issue E3D Revo

ianborg

sorry if this turns out to be a double post, but I was editing the original to make it more readable and then it said it was being marked as spam. so not sure if it will be auto removed or not

I switched over to the E3d Revo hot end.
on their support site it indicates the following config changes are needed to use the correct thermistor.

M308 S1 P"e0_temp" Y"thermistor" T100000 B4725 C7.060000e-8

my PID auto tunes take over 30 min and always seem to give warnings, is there something else I need to do?
thanks!

Auto tuning heater 1 completed after 3 idle and 50 tuning cycles in 2030 seconds. This heater needs the following M307 command:
 M307 H1 R1.456 K0.224:0.291 D2.50 E1.35 S1.00 B0 V24.6
Edit the M307 H1 command in config.g to match this. Omit the V parameter if the heater is not powered from VIN.

when i try to print i then get this

Heater 1 fault: temperature rising too slowly: expected 0.40°C/sec measured -0.40°C/sec

@ianborg This is indeed a duplicate post and I've replied to your first one.
