Hello again all - I ran a test cut this evening and things generally went much better. The cut completed at least. I just did a very simple 200mm square and circle to test accuracy after my calibration. Depth was fairly close - within .8mm. The shape profiles, however, were squashed. The square ended up 208mm x 185mm and the circle was a similar oval. Could this just mean I need to run calibration again? Maybe there has been some belt stretch or maybe adding the dust collection hose after the calibration threw things off?
Also, I am noticing that there is some slop/space in-between the arms. Could that be contributing? I realize they need to rotate freely but is that accurate to the design of the machine? It doesn’t seem like the top and bottom clamps can move too much.
