BobCad 80% off list

How are you getting on with it Robin?

Never actually unwrapped it, BobCAD called me and sold me a dongle thing that converts the V23 demo into the "reel thang", along with a full set of training discs.

I like the dongle approach 'cause I can have it loaded at home and at the shop without separate licences.

Gave it an AutoCAD outline, extruded it a bit and G-code magically appeared. Then a morning rewriting the output script thing so I got G-code I could use.

Then decided to remake the riser blocks I use to bolt metal to the machine bed, then found a bug in my mill driver software, a nasty little, devious bug so it was some time before the penny dropped.

If it did a vertical shift at the end of an arc it lost position on the Z axis

Turned out that the arc could end a tiny fraction off the required X,Y. It then scaled the Z feed speed to allow for the cut angle in the X,Y and everything went to hell in a hand basket. Massive Z feed rates, lost steps, goodnight Vienna.

Now that's fixed I can go back to trying my BobCAD G-code and cut the cheeks for the new mill Z axis screw.
