Hi,
I have some problem with all axes, if I test, for example Z axe for movement to 10 mm, wen return to 0 is stop to 0.01 and wen go to 10 mm is stop to 10.001 mm, and again return to 0, is stop to 0.02 and again to 10.002 ..................and so on. No accuracy.
I use UHU servo, and when I tested with uhu tuning software, accuracy is OK, for example wen I use G command to move Z axe, is move and go back without lose position for hundred times, but with mach3 lose position.
Any suggestion.
Tanks.
P.S. I tried and with EMC2 but result is the same.
I found the solution to the problem I was having and it turned out to be multiple problems all happening at the same time.
First, I just swapped computers so the mach3 set up was not right and I had the acceleration set to high. This was causing over travel on the down cut.
Second, the mounting bolts on my Z axis servo motor over the years got stressed and came loose. That was my fault for using crappy bolts from home depot.
and last problem was the counter balance of the milling head was not right to begin with, and thats why the acceleration speed needed to be lower in the first place.
When I set all this up 5 years ago I ended up forgetting about all the micky mouse fixes I put into place and they all came back to bite me all at the same time.
