Different time measurements on the same machines

Are the speed values absolute or in percent? Check the machine move settings but also the settings in the calibration program.

Thanks for your answer.
The speed values are ​​absolute. In calibration program we have the same move speed value.
Any more ideas?

Speed control on the controllers are the same? One isn't slower by one tick?

Anything different from observation ? For example, if check a diameter 20 mm hole with 40 hits, comparing the two machines, you can tell prehit/retact similar or not. comparing rotations.. one by one parameter, maybe you could find out something, maybe not

Good luck

Check the machine interface setup and look for the max speed and acceleration settings for each axis - are they the same? Only other thing would be if there is some sort of safety protocol in place limiting the speed of one machine. For example, some large gantry style machines have light barriers that, if triggered (by somebody walking into the volume) limit the speed.

One more thing to check after all the other suggestions - an edge case sort of thing. Make sure both CMMs are communicating over ethernet. Maybe one of the machines is using ethernet connection while the other is using RS-232 (serial) connection. That makes a big difference when calibrating an analog probe.

Hi
Tkank you for your suggestions. I will check this and give feedback.

If machine A has a total of 110 probe angles loaded and takes 3.3 hours and machine B as a total of 200 probe angles loaded, taking 5 hours... your duration to calibrate all tips will absolutely differ.
If both machines can execute an identical routine and they consume the same amount of time (± a few seconds), then all the machine's parameters are in fact the same, and you just need to cull the unnecessary probe angles from each probe file.

Look up "listfiles.xlsm" in the forum search, and learn how to use this tool, which automatically populates a list of all loaded probes and their respective angles used in your routines.
From there, you can produce a list of the NECESSARY probe angles for each machine... and then delete the probe angles present which are unnecessary. once you complete this for both machines, they will both have the same calibration times, and you might even improve on that 3.3 hours.
