General Mach Discussion / Need help with router. Slow and jerky.
« on: November 30, 2013, 07:50:37 PM »
Hello
I am pretty new to all of this so the problem could be anything.
When running the gcode the machine will shake, shudder, and slow down. I pretty much just make skis with my machine. The problem is most prevalent when the machine is going around the tips and tails of the ski running lots of code. When cutting down the sides it will speed back up and shudder less. It gets worse the faster the feedrate to the point it will not achieve the maximum feedrate in the g code
My machine will jog around all day at 2400(metric). I can run gcode that fast as long as there are not too many movements at once. When doing the outline of a ski i can have a feedrate of 800-900 maximum with no noticeable problems. Anything more and it starts to shutter. If i set the feedrate to 2000 it will get to about 1400 and shudder and shake allot.
Machine is
Ethernet smooth stepper
G540 driver
Mach3
windows 7
laptop 2.27ghz 4gb ram
Any help would be much appreciated.
