General Mach Discussion / 4th axis is slowing X, Y, and Z
« on: July 05, 2007, 06:01:48 PM »
Hi Forum,
I need some help getting Feedrate speed out of my setup... when a gCode line with only "A" on it runs all is fine and "A" is as fast as "F" is set, but lines with "A" and another axis like "X" "Y" and/or "Z" the feedrate drops to around 1.2 IPM which is like sooo very slow!
My setup is:
-Mach3 w/ G100
-4th Axis Motor Tuning settings: Steps[500], Velocity[2500] yes it's cranked!, Acceleration[1000]
-Tangential control[OFF]
-Settings page Rotation Diameters: A[+0.0001]
-Settings page Axis Ihibits[OFF] for all 6 axis'
-General Config Angular Properties [CHECKED/on] for A, B,and C
-ToolPath Configuation Use diameter For Feedrate[CHECKED/on]
My snippet of gCode is:
f50000 (cranked and still slow on A w/XYorZ)
x0 y0 z0
z-.187 (moves fast)
y2 (moves fast)
y0 (moves fast)
x2 a90 (moves SLOW!!!)
z.2 (moves fast)
x-.5 y0 (moves fast)
z-.187 (moves fast)
x0 y0 a90 (moves SLOW!!!)
x2 a180 (moves SLOW!!!)
...etc........etc.......
Also to rule out software/firmware woes I've tried different versions of Mach3, different versions of Mach3 G100 Plugin, and different version of G100 Plugin Firmware... all perform with same problem persisting.
Any help is h-u-g-e-l-y appreciated!!!
