I am having problems with mach2 and cv and i was just wondering if anybody could maybe advise.
My gantry router has been running for a couple of years and i run mach2 v7.5 (old i know but it has always worked).
Anyway i produced a file from artcam to engrave a coin (approx 21mm dia).
If i run the file and go back and check the z position it is .3 - .4mm out of position and always upover.
So i spent all day re-tuning the motors only to find that no-matter what accel i use the machine is alway out the above amount and alway upover.
So i sent the file to a friend that has mach and a milling machine,Now this mill is rock solid and never loses steps.
But sure enough whhen he runs it he is alway out .2mm - .3mm upover.
After much debate i turned the cv off and the machine never lost a step.
I have spent many hours discussing this problem with art over the years,We always seem to get the machine to run but every now and again a new file throws a spanner in the works.
Is there anything i could do in artcam to help,Or mach2?
Regards
Mark
