General Mach Discussion / Re: A posible Solution to Missing steps under Mach3
« on: November 07, 2015, 10:59:12 PM »
Solution-one option
Have been having lost step problem for ages also, tried everything i could find on the forums, nothing made a difference.
I have a reasonably modern computer running Windows7 (was XP), Mach3 066.
The steps i followed to test this solution were as follows:
Ran a stepper under Mach3 with my std configuration, could actually feel the steps missing every now and then, this was under full step down to 1/32.
Made the system changes (see below)
Without changing Mach3 at all, re-ran the test, this time there was NO indication of missing steps
What I did : Under Windows Control Panel...System and Security...Power Options..Balanced goto Change plan settings...change BOTH boxes to NEVER.
I later fine tuned the Motor Setting in Mach3 on Step to 10us and Direction pulse to 5 us, lower settings also worked but these were optimum for me.
NB: this was a bench test not on a working machine, as mine is down at the minute, but indications are good that this is a solution for me.
Why does this work...not a clue..but it seams to.
I have not seen this on any of the other forums.
Hope this helps and if anyone tries this and it proves workable please let me know.

....I figured it had to be something basic, I was just too close to the problem to see it, but talking it out with You moved my focus.
