I have a CNCest machine, bought on eBay many years ago. It runs a Mach3 controller of Chinese origin, I have upgraded the drivers to digital ones .. Other than that, I can tell you no more details.

 

It does not have limit switches, Never have I needed to set a Machine Home position, I've always just moved the spindle to the starting point of material surface, zeroed all the axis and pressed start ..

 

It's always worked in the past this way and it's only been since I started using F360 that I am now having an issue .. 

I do understand it's not F360 that is the problem.

I don't understand how to get around or work with the G28 command ..

 


You really should look at fitting limit switches so you can home the machine. If you have a fixed home you can re-reference the machine if it loses position plus you can recall offsets (G54, 55 etc.) and leave jigs\fixtures set up. The switches are in series so you only need 3 switches and a bit of wire, hopefully your controller has connections for the limit switches.
