is this correct? x 100mm/s 25mm/s^2 y 100mm/s 25mm/s^2 z 100mm/s 250mm/s^2 Lines enabled 3:04 disabled 4:50
arcs enabled 3:27 disabled 5:03 there is a fix now in 2.7 - rob when you get a chance - look it over. sam On 03/08/2015 02:40 PM, Andrew wrote: > Hello, > > Today I ran into a comparison of hobby CNC software on a russian forum.
