Machine keeps stopping?

[Lee Roberts]

Hi Kev,

This is a common problem for a few with an OmniCNC machine using a cdxhctech.com card, as I understand its related to USB and is caused by signal level, interference and earthing problems, this is also common for other brands of chinese USB interfaces.

The fix given a few times was to look at all earth's and make sure they are good and well connected, you can connect an earth to the PE of the spindle VFD if it is missing one and also look into the spindle and see if that has a good earth connection.

Before you go looking at all that though, you can start Mach3 and when presented with the option for connecting to the machine, so this would be the printer port, xpod stuff, at the bottom left of that screen there is an option that read to the effect of "dont ask me this again", choose that as well and give the machine another test run and see what happens.

Since choosing that option it has fixed the problem for people and been passed as a bug in the software, however you should check the earthing as well.

Let us know what happens next!
