General Mach Discussion / Re: Table Squaring Compensation....

« on: December 31, 2009, 04:10:25 PM »

I have shimmed it up as good as I can and it's not off nearly as much...but still off by about .003 over a 4" sweep on the X and about .002 on a 4" sweep on the Y.  Now, for some reason, the mill is now stepping over on the X axis on each program cycle.  I thought maybe the timing belt was slipping, but that doesn't appear to be it and the code is fine.  It will complete a cut and when it goes to start the same cut over at a lower depth, it's stepping over to the left and will do so everytime.  So, now I have two sets of challenges...any suggestions?

My model is the previous generation and is different than the current Town Labs model.  Here is a video of what my problem looks like:

The table surface is off when I do the sweep with the z axis.  The mill is a 512 Town Labs model.  It basically is a Harbor Freight Mini mill head/column bolted to an iron cross slide table...and has no adjustments at all.  I can post an picture of it or even do a quick video post on youtube to show you the sweep and the mill if that would help....

Thanks for the fast reply.

It's odd, when I do a sweep of the table...it's off by .026 over a 3" sweep front to back on the Y axis and .042 over 3" on a side to side x axis sweep...the table is way off.  I thought just bolting a piece of aluminum to the table and milling it flat would give me a surface to work with, but it too is off in the same way.  So, I'm not sure what's going on.  There are no adjustments on mill for anything to fix this...so, I'm hoping to figure out what I can do in Mach3 to fix this....any suggestions?

I have a Town Labs CNC mill and it has no features to square any part of the mill and it's off by quite a bit. The mill's manual speaks of some kind of compensation settings inside Mach3 to remedy this...I can't find those setting options...does anybody have any clue what to do in Mach3 to do this??

Please help!
