I recently bought a Warco VMC mill with power feed and 3-axis DRO kit for self-assembly. I've only just found time to investigate the DRO fitting and have come up against the following "problem":
The Warco specification for the Y-axis travel is 152mm. The scale they supply is a 150mm unit. Fair enough, I can live with that – 2mm is an acceptable loss. However, when I came to investigate the mounting of the scale, I found that the actual travel was 170mm. Quite a significant difference and useful to boot! My dilemma now is do I artificially limit the travel to 150mm and lose out on that 20mm or should I go to the next size up [200mm] scale and use the lot? I personally favour the latter route.
Before anyone suggests it, I've already emailed Warco ten days ago for their suggestions, but have received no reply.
Has anybody fitted DROs to their VMC and had to overcome a similar situation?
