Do we get to take a PEEK at his code?  I like to see new minds working.

(;-) TP

you'll have to wait, I've not even had chance to look at it properly yet
He's going to have to load it onto the Haas at Collage to check it'll run and looks right CNCSimulator doesn't seem to like or recognise G13 so it didn't show properly, I alway did find it a bit flacky but good for a free program.
He's then going to have to re write it for the Mach3, He's doing a turners cube by the way, with some additional holes drilled in the corners.

What about a NFS circular pocket then repeat it how ever many times you want just decrease the xy scale and increase the z each loop. Uses variables , loops and scaling all in one. When done, tool change to drill and canned cycle drill as required.

Good reminder to update this.
It turned out that only 2 people on the course had even tried to write the code, my son being one of them, so those two got to check and alter their code on the Haas and then cut it in Aluminium on the machine. The rest had to do the code but will not be able to achieve full marks for the assignment.

As is usual with a 17 year old son he din't bring the code used back for me to see.

Yea but NOW he is a coder and you are still just POPs. What do you know? 

It gets worse until they reach about 35-40 then all of a sudden you turn into a flipping GENIOUS.

Been there, (;-) TP

Probebly right there, but I can say I've forgotten more than he's learnt, mainly because I forget everything these days
