Help with BLTouch

Mike McG

@dc42 thanks I figured that out the motor Direction was wrong but the BL touch is not deploying when the G30 command is issued does the G30 command automatically call to the deployprobe.g file?

Yes (unless you are using very old firmware), unless you have previously sent M401 to deploy the probe yourself and not used M402 to retract it.

I'm using 2.01 but it's still not deploying or retracting at G30 command

Try sending M401 and M402 from the command line. If they don't deploy and retract the probe, check the wiring, the config.g file, and the deployprobe.g and retractprobe.g files.

Did you cut the trace to make it 3.3v and not 5v? Also, is the bl-touch blinking red or steady red or off?

Sorry if i missed it and I am late to this but did you post the deploy.g and retract.g? Did you do self test M280 Px S120? and M280 Px S160?

Mike McG

Well after very close examination of the trace on the back of the BL touch the trace was almost cut through but not enough it works thank you very much for all your help

Mike McG

@qdeathstar it was the 3. 3 volt logic Trace and now everything seems to be fine go figure something as small as a little Trace thanks for your help

dc42

I'm surprised that it didn't work without the trace cut.

Mike McG

I was thinking this morning I had to unplug The BLTouch To get toThe logic trace I don't think it was the trace Although the trace wasn't fully cut I think it was plugging it back in Afterwards Sounds more logical
The probe deploys And retracts When I do a homeall or homez But I can't get G 29 Were mesh Bed leveling To work Says something aboutIt must be home first Even if it has already ZYX all Show 0 I know that I'm missing something right?
Any ideas On today's Problem lol Thanks guys I really mean it I'am new to this board and the firmware So I'm in the learning curve
Thanks again
