I can't complete a project

I am new to the CNC world. I have an Axiscreat X6060. I use Vectric Vcarve design software and gSender. When I run a project the machine randomly stops. Sometimes it will start again on its own, other times I have to tell it to start again. The projects are very simple. I have contacted gSender and they suggested contacting Axicreat which I did. I have tried everything they suggested and nothing seems to be solving the problem. I have tried three different computers, checking all of the cables and ports, running directly through the control box, reinstalling drivers, and the list goes on. Any suggestions would be appreciated.

From what I can tell from online documentation, Axiscreat uses FluidNC as a firmware.

FluidNC is not officially supported by gSender and never has been, but it works well enough as long as the grbl controller is used.

The first thing I’d check is making sure that you have your fallback firmware set to grbl over grblHAL. As far as I know this is necessary for gSender to work with fluidNC at all. You’ll know this is the problem if you see grblHAL in the connection widget listed as the firmware.

You can find this option in Config → basics section

Past that, unfortunately since fluidNC is not officially supported and it’s a third party machine, you’ll be on the mercy of some community members trying to help you - I do know a number of users are using fluidNC with gSender successfully with some functionality not compatible.

Thank you, I will check that.

I think we solved the problem. The wiring going into the control box was bound together. I separated those wires inside the control box and it seems to have solved that issue. Now, when trying to home the machine, I push the home button, the machine starts, but when it reaches the top of the z axis it hits the limit switch and stops and won’t move. Any suggestions would be appreciated.
