Re: touch probe

Should work if your gcode file calls for the 3/8 bit. The X/Y zero point should remain the same unless you move the spindle when changing bits. Why can't you set X/Y with your 3/8 bit?

Re: A few more Limit Switch questions for ShapeOko 2

"If I remember correctly, you also need to enable hard limits ($21=1) when you enable homing ($22=1) in order to let it work."

Limits and Homing are independent. Can use either without the other.

Re: A few more Limit Switch questions for ShapeOko 2

Use this diagram. I don't recommend you try to recompile Grbl to swap pins. You may need pin 11 PWM output for spindle on/off later if you do not already use it now.

Re: New to GRBL with lots of questions and keen for help!

Try connecting a 0.1uf ceramic capacitor between the limit input pin(s) and ground at the Arduino.

Just reread your post - do you have soft limits enabled?

Re: Motors Stop In Middle Of Commands

You are trying to move the steppers too fast.

To quickly resolve the problem, reduce your Steps/MM ($100/$101/$102). Try 30. Then calibrate your axes for the correct value to put in $100/$101/$102.
