Title: Missed steps after upgrade
Post by: MNoble on March 05, 2009, 11:03:22 PM

I just upgraded mach3 from an older version 1.5 - 2 years old. (sorry dont remember the old version). before the upgrade everything was working  well. now with the current release i am having a missed step problem. i spent an hour or so trying to retune to no avail also toggled enhanced pulseing, still no joy.

thanks,
mike

Try increasing the pulse width on the motor tuning page.

You could also try selecting 'Sherline mode' under the 'Ports and Pins' menu.

Did try different pulse width settings which didnt help much. I will try the sherline mode this evening. even at half the speed is was running before it still misses steps, just stalls like the head bound up, which is not the case, i removed the load of the head, and even with only the ball screw and nut being driven at 1/2 speed it still stalls.
