Re: [CAD_CAM_EDM_DRO] Loosing steps with Gecko 340 drive

My guess would be that you are driving the Gecko in such a manner that the
opto is missing some of the steps. It is not faulting because as far as the
drive is concerned it is making all the steps it has been commanded. I seem
to remember Mariss saying that the opto in the Geckos is not incredibly fast
and if one side of the pulse (don't remember if it was the on or off) was
too short the drive would not notice the pulse.
