I have been having an issue with some simple text. All seems well in the Vcarve file, but when I go to cut the text it gets progressively deeper. Cut starts at the prescribed depth (.06) and when its done depth has gone to (.11). I am using a 30 degree vbit for this cut... seems as if the Z axis is having trouble holding its own during this cut. 7 lines, about 140 letters, so there is a lot of up and down on the z axis.... In the same file I have two pocket cuts with a 1/4" end mill that run in opposing directions to get a smooth surface, Z axis holds very well during this cut. Any suggestions?

Re: Z axis repeatability
Since you are surfacing the material with your pocket routine, I would think that would rule out an uneven surface, which was my first thought. I would double check that the set screws for your Z axis coupling are tight and nothing is slipping. Also make sure your bit is tight in the collet. Maybe slow down your plunge speed..

Good suggestions, I did find the coupler would take about 1/8 turn tightening.. I released both set screws and retightened. I am going to reduce plunge speed also. First have to stop by and get some cheap material to test those adjustments

Tightening the coupler, and reducing the plunge rate from 30 in/min to 15 in/min have made things right again ...

Re: Z axis repeatability
Glad it helped. I would think that you should be able to plunge faster than 15IPM though without losing steps.
