Re: [CAD_CAM_EDM_DRO] Re: Can a PC operate a BOSS 5 or 6? (and a question)

I had exactly the same problems as you. On top of lost steps I had

and now it performs brilliantly. Rapids are limited to about 100IPM
because I used undersized motors and geared them down. However that is
more than enough for what I do.
