Ok PCB milled now how to drill the holes ?

[HankMcSpank]

How long does that take ?

to do the Z probing?

About 1 minute (depends on big the PCB part is & how many probes you select) The amount of Z probes is set by the user ....eg 'probe four times in the X axis & 3 times in the Y axis' ...therefore 12 probes etc)




About 2yrs ago, I was seeking a slicker way to autocompensate for Z irregularities (all methods I'd tried up until that time were either a complete ballsache or sh1t)...at the time Andrej (CNC-USB author), hadn't offered the feature, but I pestered him sufficiently & he implemented it, so I bought it :-) ...best money I think I'll ever spend wrt PCB Milling

Just load up *any* g-code file (it doesn't have to be pcb related g-code) ....CNC-USB then gets the X/Y extremities of the part ...you tell the software how many Z probes to make within these extremities, then click 'Warp'.....& start your cutting.

It works perfectly.
