Hi Folks,
I'm doing some pre production work on my simulator on the laptop and keep getting a joint 3 following error for the a- axis.
Is there something wrong here:
If I recall correctly I set this up using the 9axis simulator configuration, changing as little as possible.
I have tried reducing max velocity and max_acceleration, and changed ferror to 5 and min_ferror to 1 as I saw used in other simulator ini files.

Hi
I assume that you are working in mm, being from Netherlands?
Does a max velocity of 54,000mm/min seem feasible to you on your machine?
Or acceleration of 1200mm/sec/sec?
Both seem hugely high.
My rotary axis on my lathe is set FERROR = 1, MIN_FERROR=0.25 with much lower velocity and acceleration.
I am sure that in the contrast lies your answer
regards

PS
Had a quick hunch and checked and sure enough,
FERROR = 0.05
MIN_FERROR = 0.01
are the figures from an imperial sim.ini file
Multiply them by 25 and you are not far from the figures I quoted

Ah, so the FERROR and MIN_FERROR figures are dimension based? That is good to know, did not read that anywhere (or just did not pick that up)
But should these numbers actually matter in the simulator? And in a rotational axis?
I also copied the numbers from my actual machine, that also gave the following error.
I'll play around a bit and see if there are thanges

All the relevant values are based upon the units set in the .ini file (LINEAR_UNITS= ANGULAR_UNITS= )
If you still get errors, attach your full configs in a zip, so that we can try to get them to work
