General Mach Discussion / Re: need help! Newbie's problems

 :) :) :)
Hood,thank you very much.You guide me to the
right direction.
I caught out that my screw drive have 5/8" diameter,
then it's TPI = 11, and pitch is 2.308 mm.
I did the changes in Step per and now all works
properly!

Thanks!Best regards.

What is the mystic number?
200 steps X 10 micSteps = 0.1 Inch Then
1 Inch = 20000, it's wrong?

Thank you.

It make me crazy,I check it many time and I get
in X axis 22mm instead 25,while in the Y direction
I get the right value.
It's not step skipping (I have spare of the motor power)
and all settings is a same to the both axis.
The screw drives of X and Y axis is construct from
the same screw 0.1 inch... ???
I am beginning think that my screw decrease
one revolution = 2.5mm,but why!!!

I built this engraver for PCB milling for my projects,then
I need inches.
Just now discovered strange thing :
After BTW procedure I got right value in Y direction - 25mm,
but in the X direction I got only 22mm...
All settings in the motor tuning is the same for both axis.

Thank you.

My Microstep Drive 103M series provide only 10 micSteps.
I am newbie in the CNC area and Ihave not DRO.
29 mm is measured with simple caliper.

 :)I did it.Now it work!!! But...
I have "standart" 200 step 1.8 deg. stepper.My Microstep Drive
multiply it to 2000 steps,and my screw drive moved 0.1 inch
per one revolution. So I expect to get the line = 1 inch,when
I send to MACH3 (in MDI) stroke command " G0 X1".
And I get 29mm. :(.
My MACH3 setup utilise inches units.
 Thank you very much.

In this moment I am trying to setup my home brewed engraver.
The problem is the scale factor. When I get any G-Code from
CAD prog. the MACH3 engrave it with 1/10 scale factor.
I think I know why.It's because my Microstep Drive.
How I can to setup the X,Y,Z scaling=10 in the MACH soft?

Sorry, I have very poor English.
