Not sure how to set the BLtouch Probe in RepRap 3
-
Hi! This is probably a stupid question, but I cannot get the BLTouch to work after upgrading to from RepRap 2 to 3. Whenever I try to use the BLTouch I get "Error: M280: Invalid gpio port 64"
I have a duet Maestro, and used the RepRap Configurator to setup the new version. I was not able to find out what "PWM Control Channel (BLTouch only)" setting was for, So I left it Blank. I wired the BLtouch as shown in the wiki, and It worked in Reprap 2. I configured it as shown.

You should also refer to this guide for manual configuration. I don't think the config tool is currently up to date for this.

Post your config.g if you'd like some specific help on what to change.

@CaptainSnowball said in Not sure how to set the BLtouch Probe in RepRap 3:
change to
M950 S0 C"zprobe.mod" ; create servo pin 0 for BLTouch
M558 P9 C"zprobe.in" H5 F120 T6000 ; set Z probe type to bltouch and the dive height + speeds -
; Z-Probe M950 S0 C"zprobe.mod" ; create servo pin 0 for BLTouch M558 P9 C"^zprobe.in" H5 F120 T6000And then your M280 command would use zprobe.mod I believe.

The documentation isn't currently clear, so I'm not sure if the Maestro requires the ^ in M558 or not, but Veti is very probably right.

I got the same result with and without it.
either way, the Z probe does not deploy, and I have to Halt it to prevent it from crashing into the glass.
If someone could fix this as well, that would be amazing. it is the deployprobe.g file; deployprobe.g ; called to deploy a physical Z probe ; ; generated by RepRapFirmware Configuration Tool v2.1.4 on Sun Dec 15 2019 20:30:18 GMT-0500 (Eastern Standard Time) M280 P0 S10 ; deploy BLTouch -
dont home but test M280 P0 S10 manually first.
can you try with
M950 S0 C"^zprobe.mod" -
So I added
M950 S0 C"^zprobe.mod"to the end of the config.g file and now everything works fine.
Thanks everyone!
