General Mach Discussion / velocity /accel

« on: July 20, 2013, 11:38:51 AM »

I am having trouble with velocity- acceleration settings! I am cutting some lexan parts and wanted to maximize my feed rate. I sat the velocity to 120" @10 accel.
After cutting the parts i have to place them in a drill fixture to cross drill a pivot hole. The shape was so far off I couldn't fit them into the fixture to cross drill !!!
Have kept slowing everything down and am now @60" @ 3 accel. Now the machine is pausing at every point where two lines meet at a tangent point (i.e. straight line/arc corner)
This an R2E3 B'port capable of 120IPM, shame not to be able to use speed on lexan!!! Anybody have any suggestions.  
 
thanks in advance for any help

General Mach Discussion / jitter onbport r2e3 to mach conversion

« on: August 30, 2010, 10:21:15 PM »

I am in the process of converting my R2E3 b'port to mach. I have everything hooked up, but when I try to run  a g-code flie it will run it once fine, but if I try to rerun the same file it starts to jitter
