My 6HC seems to think I have a CAN connected which I do not

That wroked great! Thank you, I will try the others

@T3P3Tony
I am now having issues trying to get the BLTouch functioning.
When I start the system up the probe kicks out twice and the LED stays on.

@darylprice That's normal for a BLTouch. It's in error state if it starts blinking.
-
@chrishamm
It is not blinking it just stays on until I pull the probe out -
@chrishamm
I see what you are saying. Is there any test codes I can use so it does not jamb into my base plate. Currently if I try a G30 it just says it is already triggered -
@darylprice That's normal.
-
@darylprice You can send M401 and check if the pin drops out, it should be pulled back in when you send M402. Once you push the pin in, the Z probe reading should go to 1000, if it doesn't, you probably have a wrong input port selected or a wiring issue.
-
@darylprice have you worked through the documentation here:
https://docs.duet3d.com/en/User_manual/Connecting_hardware/Z_probe_BLTouchand:
https://docs.duet3d.com/User_manual/Troubleshooting/BLTouch_troubleshooting -
@darylprice Also your servo pin is inverted (see the
!before the port name inM950 S0 C"!io4.out" ; create servo #0 for BLtouch). That shouldn't be there. -
@T3P3Tony
Yes I have, I am trying to understand it all. I am using an original BLTouch version 3.1.
-
@chrishamm @T3P3Tony
I have put the Black and Brown wires together since they are both grounds -
@chrishamm
I found that the P value in the M280 P? S10 command does not want the P9 (for a BLTouch probe), but a P0. It works now with that. I found that on the BLTouch web site -
@darylprice the correct P value to use in the M280 command is the value you used for S in the M950 command to assign the servo pin.

I want to personally thank all of you for helping me. I know you have to deal with us newbies all the time.
Hope I listed all of the people who helped. I am sure I will be reaching out again.
Thanks Daryl -
@dc42
Quick question. What is the safest way to shutdown my printer before I cut the power?
Daryl -
@darylprice just pull the power. theres no shutdown needed
-
@darylprice Are you running in SBC mode or standalone?
-
@gloomyandy SBC PI 4
-
@darylprice in that case shut the pi down first.
see here https://docs.duet3d.com/en/User_manual/Machine_configuration/SBC_setup#shutdown-or-reboot-sbc -
@darylprice That's quite odd. In order to replicate this issue I got an original BLTouch and that one works well with the PWM values generated by the configtool.
