Well it's finished and it works. Well 99% finished anyway....
It'll do 275mm on each axis. Mainly cutting perspex.
Just starting to work out cutter speeds and feed rates. At the moment it's running with the Dremel flat out and a feed of 7mm/sec which is about 1.4 ft/min. I think the rpm's are too high as the chip is very small. If i increase the feed rate the Dremel starts to run out of grunt (3mm cutter). So I should either reduce the cut depth so I can increase the feed or drop the rpm.Correct??? Would welcome any thoughts on suitable feeds and speeds.
Thanks
