Im am trying to work out a routine for checking our arm.
How do you guys do ?
Do you use the check bar that was included with the arm or have you made an own checking routine ?
I have made an own "checkbar" to test the arms repeatability.
The bar is 1,5 mm thick and 1200x150 with 6x Ø25 holes
Made a program and measured in the the alignment plane-line-line (intersection point line-line) and then measured in the holes as 8 hit circles.
Now when I re-measure the circles over and over again and evaluates the X-Y possision i get aprox a diff off ±0,06 mm
Is this a normal result off a arm ?
When I read the spec off the Romer sigma 2025 it says ±0,034 lenght (but i figure this is if i measure between 2 points)
How do you do with the probes ?
Do you run the Romotic GDS probe calibration once a while or just run the .gds files that comes from hexagon after the annual calibration ?
