I actually have it tunning ok now but I am still unsure what was wrong to be honest, I basically configured a brand new profile from scratch and it is now running at normal speeds but for the life of me I can not see any difference between the two XML files

General Mach Discussion / Very slow feeds when cutting arcs

« on: February 04, 2015, 03:33:31 PM »

Hi All


 I have just set up a machine and I have done some test cuts, if I do a test with a square pocket the machines cuts fine but anything at all with any kind of radius or circle in it the feeds just drop down to an absolute crawl and I can work out why.

the maximum velocity in my machine is set to 750 and if specify a square pocket with a feed rate of 750 the machine will cut it fine and mach3 behaves as it should, if do say a circle and specify any feed rate at all it disregards it and cuts at a feed rate of about 5% so a 6mm hole in a piece of mdf takes about 10 minutes to cut

Originally I thought it was an issue with the code being output by bobcad but I have since run the circle cut wizard in mach and still have the same problem

 I really hope someone can point me in the right direction as I am pulling my hair out here

 Cheers
