So I had to update the GRBL on my machine, which I did. The machine began to home and it shot down right into the Wasteboard, the poor marker was just being crushed. Then I tried again and instead of down the tool head jammed up and was grinding against the top during the supposed homing cycle.
Is this a limit switch issue? Wiring? I spend so many hours putting it together carefully!
I entered /$23=1 for the homing I think…I clicked the button but not sure it DID anything.
Which Grbl did you update to using what settings? Suspect you have Nomad defaults — please see:
For the homing switch — check that the switches work — they should be able to be engaged mechanically by the machine and they should light up the appropriate light on the controller.
Could be a stepper plugged into the wrong port on the control board. Double check those. Have you done a “send config” from Carbide Motion to set the initial config for your machine? If you’ve updated GRBL to 1.1 you’ll need to be using a v4 version of CM and no manual entering of the $23 param should be required.
Okay I missed a pin on my limit switch, up and down is now fine I think, however the machine was homing and when it got all the way to the right rail (Y2?) it started to grind again. All wiring looks to be exactly how it is on the guide.
heres the limit switch, I THINK its supposed to be mounted this way, that way it contacts the endstop. However it doesn’t fit in this orientation. Perhaps I have mounted the entire plate thats its mounted to wrong?
I will go back and double check but I thought everything was A-ok.
