As I stated in my first Post (1st [Post] ever):
RE: with more detail
I checked the X movement out measuring 6" ((2) 1-2-'3' blocks against a stop, measuring leading edge to leading edge with an electronic indicator (same direction of travel)), Mach3 DRO = 5.994 (measured several times, always varied by about .001, this seemed to be the average)...
RE: set up
The 1-2-3 blocks were trammed straight with an indicator, secured, and checked with mic's to make sure the over all length was correct before the test measurements were taken.
Measured the Y movement over 4" travel ((2) 1-'2'-3 blocks), Mach3 DRO = 3.995 (average, using same set up as above))...
The test cuts were made in (2) materials, Delrin & Glass Filled PC, with the exact same results, the pockets were measured with gauge blocks, and the boss was measured with 1" mic.
What is my next step to correct this problem?
