Answer Hello joaverage.
Currently, the control box for Mach4 is about to be completed, so I have some questions about Mach4, so I asked.
When the control box is complete, give it a try.
The photo shows the control box for Mach4, MB3 and ESS.
The workmanship was good. I'm sorry to brag.
I posted the photo because I thought joeaverage would understand it.
We look forward to your continued guidance.
