Good point, Hood, and thanks. I assumed so since I cut the vacuum plenum in stages; i.e., gaskets, zones grids, etc., and (ignoring Z for the moment) the raised areas between gasket and zones in both X,Y remained visually and (measureably) accurate between cuts using same X,Y=0
Is there a definitive method for checking X,Y,Z accuracy? I can imagine a few tests.
These machines are an open-loop system. There are no limit switches in the extreme X,Y and when I first received this machine, when moving the gantry around, it did "bottom out" and bump a few times. In fact, the Z sensor was bent and it did the thumpity-thump until it was corrected.
I recently learned from two other owners of Camwood machines that banging of the machine at the end of travel can cause stepper motor problems, not to mention bent gears. I've recommended to the mfgr. that they put limit switches in these extreme locations and I understand that they are now doing that as well as assembling and testing their machines at the factory prior to shipping. I've asked for a tech to come out and give it the go-over as they do at the factory since I'm in urgent need to use it currently.
This machine, in traveling how many thousands of miles from China?, I can't imagine that something doesn't go askew with X, Y, and Z. I'm waiting for a response, but they've been
good to work closely with me so far.
Thanks again for your insight.
