Help: 10x error in DRO and real movement....
« on: January 07, 2013, 02:16:39 PM »
Setup: Sherline 5410 (mm machine, 1 rev = 1mm) , G540 (10 microstepping), KL23H2100-35-4B motors (200 steps/rev)

When I installed Mach3 with G540 inst file I had 20000 in Motor tuning/Steps per. Problem is that my DRO shows +1.00 (mm) when I move +10 (mm). Othervise systems works fine.
On the other hand if I follow the instructions I should have 2000 in 'Steps per' becouse 200 x 10 x 1 = 2000. If I use 2000 then DRO is ok but mill is super (10x) slow.

I'm doing something silly, just don't know what. ???

2000 is correct if your screws are indeed 1mm pitch.
It is the Velocity in Motor tuning that sets the rapid speed, sounds like you need to increase that.
