Hello everyone,
This problem really has me really confused. I'm currently cutting a part on my CNC router parts 24x48 kit. I've run a few operations where it seems like nothing is wrong, but in the last few cuts, my z-axis has ended up significantly off from Home.
One operation I ran the other night I ended up at least +.75 inches above zero on Z. After this operation I tried to tighten everything I could tighten on the Z axis assembly, re-zero'd the machine and ran the same operation. I had no issues, the part cut as expected. I figured something must have been loose. .75 inches is a lot of steps to lose.
Today I just made a cut and half way through the operation, I realized the router bit was no longer touching the work surface. I stopped the operation and told Mach 3 to go to zero. I was at least +.25 inches above where I had zero'd my Z. X and Y looked fine. Again, I'm off in the positive, and had I let the operation run longer I may have been significantly further off.
I'm currently only cutting insulation foam at 30 IPM with a 1/4 inch carbide endmill. so there is virtually no significant cutting forces that could be causing me to lose massive steps.
HELP! Does anybody have any idea what could be causing this sort of position loss? It only seems to be happening in the positive (UP) direction.
