Seems like the data collection would work with a python dictionary. For example you set up a dictionary entry for how many ranges they want then each time a board falls inside of a range set by the operator you increment the integer for that dictionary entry.

[Emc-users] Knee mill w/ encoder on knee

2012-09-14 Thread Stephen Dubovsky
I was wondering...(can you smell the smoke?) On manual knee mills there are often ways to combine the knee and quill scales in the DRO to directly add/subtract from one another, giving only one combined Z reading. This part would be easy enough to do in HAL on a CNC. Add/subtract the quill

Dave, The knee typically isn't under CNC control on a knee mill. You move it up/down manually, lock it, re-touch off, and continue a program. Just wondering if its possible to keep track of the Z location w/o causing LCNC from running into the soft limits. Andy, Ok, joint level: that makes some

Przemek, As I said to Dave, there is almost never a power drive on the knee. So, figuring out which to move via CNC is a trivial exercise;) But you have to move the knee between operations for different length tools all the time. And the quill of a BP isn't the stiffest thing around so you
