Re: lost steps

The software I am using is Lcam and the 0.25mm diameter is the offset
required to get a 5 mm hole using a 3/16" cutter.
the software has been checked out with a Larken board and that does
not lose a single step.
I have 2 machines one with larken drivers and one with Gecko's, both
using the same software. one loses steps and the other doesn't.
has anyone else had this problem?
