Only if your trying to run g-code more than 500 lines of code and it wouldn't cause stalled motors it would just stop moving.

As a matter of interest what Voltage is your power supply to the drives?

I was just about to ask the same. Is the Voltage at the right level and 'clean'?

That said, it does feel like a Mach 3 config issue, look at the end of the vid, the DRO numbers look to pause and then unpause ...

its getting 24.4v

its getting 24.4v

Is that what the drives need? Sounds low to me but could be correct, not looked at any specs etc

[Davo242]

what should the normal voltage be ? is there any way i could send u the maual for the drivers?

There isnt 'normal'. I tend to see 50-80V usually. What does teh specification of the drivers say?
