@phaedrux Yeah, no, I got the BL Touch working on the Maestro, but now I'm on the WiFi and I do not understand why I can't get it working on the WiFi.

Phaedrux

@noskillzengineer Sorry. Brain malfunction.

Do you have a config-override.g? It's possible that your M037 H3 A-1 C-1 D-1 is being overwritten.

NoSkillzEngineer

@phaedrux why yes, I do. I'll try putting that in the override file.

Phaedrux

@noskillzengineer You can add a ; to comment out any existing M307 in there.

[;M307 H3 A340.0 C140.0 D5.5 S1.00 V0.0 B0]

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

Apparently I was overwriting my M307 command.

Commented out that line and for good measure added M307 H3 A-1 C-1 D-1 into my Config override file, restarted the board, and it works

Thank you, I wouldn't have thought of that!

Phaedrux

Glad you got it working.

I should have linked this yesterday. https://duet3d.dozuki.com/Wiki/BLTouch_Troubleshooting

NoSkillzEngineer

@phaedrux lmao yeah, I wish I knew that link existed. That needs to be linked in the wiki under "Connecting Z Probe" under "BLTouch" with the other links there. That would've solved my problems haha.

I just noticed my temperature sensors read 37 and 39 C for the hot end and bed, respectively. Same configuration that I had on my Maestro. Why would it be so far off from room temperature?

Done.

What thermistor are you using?

Veti

@noskillzengineer

the maestro has a 2k resistor for thermistors. the wifi 4.7k you need to adjust the thermistor line

NoSkillzEngineer

I didn't realize the WiFi was so much different in that regard. It's the stock Ender 3 thermistor.

; Heaters
M307 H0 B0 S1.00 ; Disable bang-bang mode for the bed heater and set PWM limit
M305 P0 T100000 B4138 C0 R2200 ; Set thermistor + ADC parameters for heater 0
M143 H0 S120 ; Set temperature limit for heater 0 to 120C
M307 H1 B0 S1.00
M305 P1 T100000 B4725 C0 R2200 ; Set thermistor + ADC parameters for heater 2
M143 H1 S280 ; Set temperature limit for heater 1 to 280C

What would I have to change and to what would I have to change it to? My thermostat says my temperature is 73° F or about 22.7/22.8

Change R2200 to R4700, or leave out the R parameter altogether so that it uses the default value for the board.

NoSkillzEngineer

@dc42 Leaving it out entirely resulted in 23.5 degrees celsius which is 74.3 degrees, thank you so much for your help! I'll remember that from now on.
