Hi,
Thank you guys for all the replies and please, excuse me for all the
mistakes I have made in my e-mail, I know how annoying these thing can be.
Corrections to John:
1. You are right, I am using stepper system with metric units on EMC2.
2. I did make some mistakes (and I must have created a bi

A full step drive would require very fine screws for that scale, a
microstep drive would use 2mm s

For some reason, I think I recall feed forward as being useful for
friction compensation.
Does that make any sense?

At present, emc2 doesn't have any friction compensation. However, there
are several avenues you might go down to add it: in the motion
controller, or as a HAL component.
At first glance, it looks like the place to add this in the motion
controller would be in the function presently known as

Hi,
I am at the state of configuring our stepper driven milling machine and came
across an interesting issue.
I set up all the parameters needed to drive an axis including backlash
compensation. Most important values are as follows:
SCALE = 1000
BACKLASH = 0.004
Then when I hook up a digital micr
