No matter what I do, I can’t get my work area exact level enough to have the proper depth when milling my PCB on my DIY CNC machine, (I’m always cutting to deep some areas and to shallow others). always around 0.0050 off
(I’m going to try routing the work area level again).
However,
Is there any general sensor method I could hookup that would act as a
depth guide ?
Example:
If I mounted something similar to a spring loaded thin metal ball point pen
To the base of my spindle, so that it would complete a circuit (similar to a touch off plate) When ever it touched the copper PCB, then I could use it as a depth guage to control How deep past the pen’s contact point I drilled.
I would always adjust the Z position relative to the contact point of the pen.
Has anyone done this ?
Is there anything like this, How can I do it ?
Thanks,
