Ok this is driving me nut.
When I first start out, I set the Software unit to MM, but I left the Step per Unit as (2000) Like in the Mach video. Then to get my motor running smooth with that step, I max out at 20 for the velocity and 20 for aceleration. Then I run the roadrunder g-code, then it cut out like a 5-6inches roadrunner, it seem fine (but im not sure if it was the accurate dimension).
After I change the step to 125 step, but then I have to raise my IPM to like 300 to get the motor to run smooth like before. But now I test the roadrunder... and it all screw up, it only cut such a small area.. maybe 10mmX10xmm, so it wasn't even showing anything....
Any idea? |
