If the error is linear then you can tweak the hm2_5i25.0.7i76.0.0.spindle.scaemax parameter. (I guessed the name, but it is something like that)

OK, will give this a whirl later on today. Now fullservice on my coffee machine that is high priority ;)

Coffee is vitally important. Get that fixed first! I had mine serviced earlier in the week!

OK, tried and this is now very close to correct rpm BUT I cannot command 1824rpm or more
setp hm2_7i76e.0.7i76.0.0.spinout-scalemax 1825
setp hm2_7i76e.0.7i76.0.0.spinout-maxlim 3000

So is there something in INI to be done?

#********************
# Spindle

[SPINDLE_9]
P = 0
I = 0
D = 0
FF0 = 1
FF1 = 0
FF2 = 0
BIAS = 0
DEADBAND = 0
MAX_OUTPUT = 3000
# OUTPUT_SCALE = 2500 >>>>>>>> is this something to play with? Copied this from another setup
ENCODER_SCALE = 5000
OUTPUT_MIN_LIMIT = 90 >>>>>>>>this is original min rpm but I take what I can get now 175
OUTPUT_MAX_LIMIT = 3000

Did a test with manual and max is 2000+ so I will settle for the settings now. This Vfdmotor combo is temporary for now.

Now how to test treading?

You can manually start the spindle and just enter a G76 command in the MDI window.
