G-Code, CAD, and CAM discussions / OFFSET ERROR !
« on: October 26, 2018, 07:02:03 AM »
I have a small 3-axis CNC machine and I design my work with AUTODESK INVENTOR HSM and export it for MACH3, in simple work with less g-code lines it has acceptable error but when machining a large file we have error in both X, Y axis.
let me show you:
it's my X axis: you can see each Z level it get more offset to right on X axis!
it's Y axis: it's so better but still it have have same problem to left
you can clearly see this error from top view
my machine have three 1.8 degree stepper with 16 level microstepping
X axis screw is ball-screw 5mm/turn
Y axis screw is lead-screw 2.5mm/turn
Z axis screw is lead-screw 8mm/turn
my controller is MACH3-LPT
please help me in this matter
