Yes it's puzzling me. I agree Mach 3 is the way to go but the machine came with this pendant so I will try and make it work for now if I can.
The file is 123mb (an other is 105mb, neither run) and the internal memory of the pendant is 128mb so I'm not quite sure where the missing storage space has gone.

If anyone could convert my router to Mach 3 for a reasonable price I would defo be interested. Likewise if anyone could boost the memory of the pendant.

I am currently trying to circumvent the issue by dividing the cutting file into parts, to machine seperately on the same workpiece ( a pain in the arse). I have encountered another issue that's baffling me. Using the sub-segment facility in Deskproto, the finish file doesn't seem to coordinate with the roughing file. i.e the finish pass cut is cutting too shallow and then too deep. It vaguely resemble the roughing pass (I left a skin of 1mm to take off with finish pass), but is out by +- 5mm. I have double checked the origin and z level zero and it's all good. I am doing another sample as we speak to see if the same problem occurs. I am wondering if there is a bug in the sub-seg feature of Deskproto or whether I've overlooked something obvious. I'll keep you posted.
