Bed thermistor setup

Could it be something with my bltouch? I think that's where that heater3 errors is coming from.

M307 H3 A-1 C-1 D-1 ; Disable heater on PWM channel for BLTouch

Remove that line. Not needed in RRF3

@ross said in Bed thermistor setup:

G29 s1 P"heightmap.cvs" ; load the mesh

Also remove that. Best not to load the heightmap until after the Z axis has been homed with the probe.

WiFi firmware version 1.23

Also looks like the wifi server wasn't updated. I suggest you upload the full zip file again to the system tab in DWC just to make sure everything is up to date. Don't extract it first, just upload the whole file.

@phaedrux ok I did that but bed thermistor still says -273.1. And thanks for the help.

Phaedrux

If you swap the bed thermistor and the hotend thermistor does the -273 follow the thermistor or stay with the port?

ross

@phaedrux so if I plug either temp probe into e0 they work but either on e1 I get the -273.1

@ross e1temp is not defined. e0temp and bedtemp are. bedtemp pins are here:

@droftarts well look at that! If you plug it in the correct place it works, who would have thought lol.
Thank you for wasting your time on me.

Where exactly are you connecting the thermistor?

LOL glad you figured it out.

@phaedrux he did say e1temp in the post after you asked that! Guess we all missed it for a while!

@droftarts yea I had it in the e1 port not realizing it was for a second extruder. I guess that's why it's labeled "E" for extruder lol. I haven't used the printer for a while and messed up the connection. It's all good now doing an auto tune pid as we speak. Thanks again guys.
