New X-Carve owner, just set up my 1000mm device and I've calibrated it so the wheels run well, and the X and Y motion is smooth. I'm having a problem with artifacts in Z, however... it seems to be creating "steps" at weird places. I doubt this is a calibration or mechanical slipping error, since the gcode is causing curved steppes within the design, and I've watched the spindle move up and down smoothly and it's not catching anywhere.
I'm using Vectric's PhotoVcarve software to do a test; it's a bowl shape with dome in the center. The small center dome is mostly smooth (albeit with a vertical ridge, which is odd), but the shallow bowl is not curved but stepped. Here's an image of how it routed out:
The original was supposed to look like this:
I generated gcode with the X-carve post processor (inches) and sent it to the router using Universe Gcode Sender.
I'm really hoping it's a software issue caused by my n00biness, rather than a hardware or electronic issue. I can also post this on Vectric's forums if that software seems to be the problem. Any help finding the core problem (and solution) is much appreciated!
