I don't want to fault the software, but the problem I was having did go away
when I changed to EMC. When I was cutting a circle segment at a low speed I
would frequently lose steps on the X axis. If I just made linear moves I was
OK. It seems in the circular moves I was hitting and trying to stay at some
speed that the combination of motor, machine and software just did not like.
As I have said, once I moved to EMC with no other changes I was able to make
the same cut without any loss of steps.
As far as the question of whether you will have a problem or not, that is a
good question and only time will tell. I can tell you that on my machine 18
ipm was about the best I could get reliably with DeskNC. On EMC with the
frequency stepper driver I can get 72 ipm reliably and am running it at 60
ipm just to keep some cushion.
