Hi there..
I've just updated from version 3.042.020 to 3.042.32. But now my machine runs 20-30%faster than before which could cause mechanical step loss...
I have already retuned my motor settings. But when I set maximum step velocity to 3000 steps it runs approx. 3900 Steps.
2000 results in 2600.
With the old versions the motor tuning settings were OK.

This happens when jogging around. Also setting speed with the F command results in faster step rates while executing programs...

What is going wrong?

It's working the same here.
And I have pulsing speed set at 35kHz. In diagnostics shows me it pulses at 49.5kHz.
Same for 25kHz setting it pulses 35kHz, for 45kHz setting it pulses at 65kHz.
Speeds are faster for this ratio in Jog and Feedrate.
Tried DriverTest it passes OK.
Also tried NormalDriver.bat and SpecialDriver.bat with same effect.
Tried to reinstall and still too fast.

Please Experts help me.

You set the steps per based on calculated values. There is a write up in Members Docs on how to calculate the step per unit. So make sure you have that correct before tuning.
Velocity determines how fast your axis will move and accel is is the time to go from rest to velocity / reverse is true for deccelerating.
Make sure you click "save axis settings" after changing any settings.
There is nothing to be gained by setting the pulse rate higher than what is required,so if 25k is adequate for your steps per unit there is no need to go higher.

I have not seen what you are describing if your steps per unit are correct.

Hi Rich,
Motor tuning was done OK, it works correct.
It's just that in Mach for F7000 it moved 10500 in units/min and machine moved at 10500 too.
It was pulsing 35kHz at setted 25kHz in ports and pins section.
I reduced CPU speed on computer from 3Ghz to 2Ghz. Now it's pulsing 25kHz at setted 25kHz.
