This may be more of a Mach3 issue than a MechMate issue, but I'll ask here because many Mach3 settings seem machine specific.
I have recently been trying to cut some sample shapes and my results are not great. When I create an ellipse in Cut2d and cut it I don't get a very accurate shape. I've had mixed results with circles too, I suspect it may be a CV setting issue, but I'm not sure. Below is a picture of the screen of Cut2d showing what I'm supposed to be cutting and then a picture of what was cut. The circle is clearly screwed up and the ellipse is not an even shape. The square has one softened corner (CV issue?) but the size is right on, and it seems square, I haven't squared up my gantry yet, but I'm sure that's not causing the issues.
I am using the OM 7.2 reduced motors, 30 tooth pinions, a gecko g540, mach3.
My Motor tuning settings are Velocity 490.86 (It won't let me go higher), Acceleration 25 (10 on z).
In the general config dialogue I have Motion Mode CV, Distance Mode Absolute, IJ Mode Inc, CV distance tolerance 180, and g100 adaptive nurbscv is selected.
I'm sure there is some setting somewhere that will fix my woes, but I can't find it on my own. Anybody have a good suggestion?
