Hi
I started with Mach 3 a few weeks ago and haven't been able to resolve an issue, so I am looking for some help.
I have a Gantry Torch cutting setup and am using the plasma profile. When I do a test like X30 Y30 it is very very accurate. When I do a 4 in. circle my Y axis is +0.187 in. and X axis is -.0625 creating a very symetrical oval. All motor movements are very smooth.
Here is what I have tried so far; Exact stop mode enabled
Eliminate any compensation modes
absolute and incremental modes
G12 mode
changed ramping rates, this did help, X axis has 2/1 ratio, Y axis is 1/1
Backlash on both axis is less than .015
Switched Gecko drives, no difference
installed new shielded cable thru the entire system
1.8 Ghz computer with 1gig ram (ouch!)
I have tried everything I can come up with, maybe someone can spot a simple fix I have overlooked. Any help is much appreciated !
Very Frustrated
