Hi everyone,
I'm new to this forum but glad to be here, i have a strange problem that i'm hoping someone can help me with.
I have a 3 axis router, 3m x 1.5m x 350mm gantry type. I have Mach 3 and i have just finished building it and i am soo looking forward to running some code, (its my first build) but therein is my problem, when i "Ref all home" it does exactly what it should, if i "go to zero"... no problem, i can type a line of code on the MDI and it executes without a hitch, but i cant run a gcode without all the axis's going scatty, they make jerky movements big enough to shake the neighbours house.
I chased EMI around for about 3 weeks till i realized its not that, i did have a little trouble with that (emi) but i re routed my spindle cable and it is sorted.
Does anyone have any idea why i cannot run a code through mach3 without this jerking.
I tried some of my own code and i tried the default road runner but i get the same jerky movements, i cant let it run for more than a few seconds, its too rough. My motors are fine, my break out board is ok, my micro stepper controllers are ok, the spindle is ok, it just wont let me run gcode from the computer.
I think it is a mach 3 setting somewhere but i can't find it. Any ideas?
Thanks in advance
