General Mach Discussion / Feed Rate is too slow when interpolating
« on: October 15, 2018, 04:45:30 PM »
Hi,
I have a quick question. If I'm machining something that uses simple commands (circle, line, arc) I can hit my specified feed rate no problem of course in these scenarios, mach is feeding data to the controller a lot slower. My machine currently runs 4000mm/min on the X and Y axis travel.
However if I run an adaptive strategy for a toolpath, where it is constantly outputting (X,Y) coordinates to interpolate a circle, my feedrates are limited to about 700-1000mm, and it varies, increasing as the radius of the circle increases but it stalls out around 1000mm/min and refuses to go any faster.
My question is simple, what is causing this? I don't know if it's an acceleration limitation, or perhaps my old windows XP machine with 1Gb or ram can't keep up?
I appreciate any insight!
