Well, I have OneCNC XR Professional and that is where the part program come from. I made a 2" hemisphere and a did a few operations on it. Anyways, I was cutting air above the tabletop.
The machine will do simple moves already. I haven't had a problem with that since I rewired the machine with the differential drivers for the encoders. I have tuned the servos although (to me) it seems like there is a wide range of values that will work adequately.
I don't think the problems I'm experiencing are coming from the controller (Mach 2) on up. I set the accelleration low (30"/s/s) in Mach 2. I then ran the program and you can tell when it is going bonkers. The pauses and the subsequent accelleration is more in the 150"/s/s range (it is really rough). It's the same type of accelleration you get when doing the tuning software. So I am assuming there is error in the servo's current position versus the intended position. |
