is the tool running
or did you use a Precision PIN
Calibrated pin or diameter
is the Z Axis Straighten

The tool is not running, its probe with cable. I have calibrated the tip of the probe by spinning it and touching with a DTI.
What precision pin? I am testing it on a ballbearing which has precise dimensions
The machine is an 900kg SyilX7 mill, so the column is straight and however the Z travel is about 5mm

How far does the probe tip have to deflect before it triggers?
What type of probe is it?
0.2mm seems a lot, but I have heard reports of some probes being that bad.

Any idea where can the 0.2 error come from?

If you probe a 100 mm distance, do you still miss by 0.2mm?

This is the probe
www.sorotec.de/shop/3D-Finder---3D-Measu...411.html?language=en
It trips in less than 0.01mm so if I jog back and forth with increments of 0.01 its gonna trip/untrip the probe.
I've went to smaller divisions and I saw that the precision is about 0.006
I am using 30mm stylus with 2mm ruby ball.

Haven't tried that yet, I tried to stick to the ballbearing dimensions that are accurate enough so that I have a reference.

Are you able to build that error into a probing routine?
Get yourself a ring and probe it and whatever you're off with just the probing routine until it reads correct.
I guess it easier to cheat the ball size though

Is the error constant with probe velocity or does it reduce with speed?

(Supplementary question) Are you looking at the position that the probing move stops in, or the values in the probe result parameters?

Once I get to the shop, I'll come up with a video showing the response to all questions, perhaps you can spot something that I'm doing wrong
