I will post more pics..just a little messy at the moment

[cnckeith]

we don't care about the mess, you should see my desk.

ok i see why you can't home, you don't have any home switches assigned. home switch is for homing. limit switch is for hard limit stop.

if you want a switch to do double duty and act as both a limit and a home switch use "HomeLimit"

[cnckeith]

like this.

Roger that. I will re-assign

then set the homing direction so the machine homes in the direction of the HomeLimit switch. choose automatic homing

in my example that would be negative first axis (M91)

and positive second axis (M92)

like this.

and be sure to set the soft limits so you never hit the limit switches while running/jogging the machine.
in the axis config menu.

have you run the PC Tuner on the CNCPC? im looking at the error log and yesterday you had a lot of com errors.

Pics of my controller so far. I have all 8 steppers (6 drives) connected. i repurposed the PC case the old controller used and I was not prepared for the size of the AcornSix board (i see why now) so things got tight. I have 4 drives mounted to the back panel of the case so when I remove 2 screws I can take the back panel off and expose 4 drives if need be. I mounted one relay board to the cover (thanks for the holes) and I still have the MOSFET board attached that is not going to be used. That will be replaced with a fast SSR capable of PWM and can handle over 36volts. So its just on/off for now. Output 7 will trigger 12v (off a buckstep module) to power cooling fans on M3 and also a flashing 12v safety light to signal a hot wire. It can be hard to see the wire.

Right now I'm dialing in cut settings (feed rate/power/dwell). These machines drag the wire a bit and you need some dwell in-between lines of code to allow the wire to catch up for sharp corners.

Yes I did. Someone mentioned that early on as well. However, I have not received any error messages yet. So I guess I will tackle that when/if it starts to pop up. (??)
