I have went to the Setting Tab and moved my y axis to the center line of the table and just off the mechanical limiter switch, I then entered 14mm hit OK and the y went 7mm 1/2 of what I want?
I have moved the X to the left and just touching the limit switch,  entered 14mm  and got 14 mm and Mach3 asked if I wanted to set the the X to 4000 steps per Unit? I replied yes,
What is wrong with the y.
I have moved Z to the top and dropped it -9mm and that was acceptable, Z axis will be set to 1800 steps per.

Craig,
This is where I get totally dumbfounded, I think the LIMIT switch is the one you install at the end of an axis to shut the machine off before it can cause damage to itself.
Home switch is what Mach3 controls and is installed  digitally.
I also need some help on this LIMIT switches, I am using a HobbyCNC control board and pin 13 for my LIMIT switch also I should mention that I am using a UC100 instead of the Parallel cable. Where do I set my limit switch in Mach3
Thanks for the help
As always
God Bless

Settings (ALT6) Tab
X axis, I told the machine to move 20 mm and all I got was 10 mm  pondering this huge discrep the machine must have moved the X only 10 cm .
I do have a steel flat ruler taped to the bed so as to get excellent readings

I just cannot seem to get it through my head, I have been watching You Boob and it all seems so easy although each person has their own way.

Hello all,
I have my Hard Limit Switches glued to the chassis and wired in series and when any of the limit switches are contacted the machine stops. X travel is 50.0000mm and my Y travel is 60.0000mm these numbers are when the machine just moves the switch.
Now how do I set the soft limits? On the X travel do I start at 50.0000 mm enter this in max and 00.0000 in min and hit enter.

Best Regards and God Bless

I am so new at this one hell of a learning curve, My one motor on the Y AXIS is what I call binding I can turn it to the + just so far and it stops. same for the - AXIS then I get a Code G90, G91 State , also when I turn the controller on the Y motor makes a loud banging noise ( just once). I have removed the motor as I needed to know if the motor was at fault for grinding to a halt or is it the NuT and screw jamming which they are not.
Thanks for the help
