Ender 3 + bltouch configuration.

the-big

Hey all.
I updated my RRF from 2.2 to 3.3.
But it seems some problems with bltouch and heaters and fan too.

When I try to home z it goes down without triggering the prob.
the heater of bed not heat

Error: Heater 0 fault: temperature rising much more slowly than the expected 1.3°C/sec

i can see only 1 fan on DWC insted of 3 i had on RRF 2.2

@the-big

I would verify the exp.heater3 pin is in use for the BLTouch. I am using heater7 otherwise it is the same. does it work differently when you "homeall" vs "homez"?

the heater rising too slowly is an known message and you can fix it by PID tuning (the better explanation is on the duet website)

My fan line is pretty similar to yours other than using S1.0 instead of S1 (doubt that would make a difference). Do the fans still work though?

@jnofsinger
Thank you for replay.

I solved this problem as the homeall.g and homez.g was broke. Now all work fine.
May you post link for me. This is the only problem prevent me the print.
Should I see it on control?

Were you able to PID tune your bed heater?
