Losing steps

Was the first carving program also 3D or was it 2D? Becuase 2D worked fine for me, but not XYX movements at the same time.

I'm wondering how complex your first "3D" carvings were?

But if this is a repeat of a carving that has already worked fine a couple of times, then forget I said anything!

Look at the picture he posted up you can clearly see it's 2.5D so it's lots of Z moves. I think it's probably pushing the machine too far regards feeds n speeds. If it's not slippage.

When I stripped it down it was sticking at the bottom of travel on Z axis, I lowed the spindle so as to miss out the bottom of screw, I try and do it slower and see if that works ��
