X-Y steps seem wrong
Hi there. I’ve been trying, without success, to rout a PCB using the Boxzy CNC head. Because the unit has a height difference of about 2.5mm from front to back I first routed a pocket in the sacrificial material and mounted the PCB material in that pocket. I was hoping for a near perfect flat/level surface to rout out the PCB tracks. After repeated failures I looked at the result with a microscope and noticed that the tracks are wavy and the square pads are nowhere near square.
My questions are, is there a way to calibrate this to make square things square and what’s up with the wavy tracks? Here is a picture of the routed PCB compared to what it should look like. (Hmm… I have the PCB material taped down securely but I will look into this.)
Is this a good question?
