Good idea, but not sure if that is correct here are the specs on the motors...not much info but you could be on to something.
Product Parameters:
Product name: Bipolar 42 Stepper Motor
Holding torque: 0.46 N•m/ 65 oz-in
Working voltage: DC 9-42V
Rated current: 1.7A
Resistance: 2.1 ohm
Inductance: 4mH
Rotor inertia: 55g•cm2/ 0.30oz-in2
Weight: 0.28kg
Length: 39.5mm/ 1.56 inch
Phrase: 2
Step angle: 1.8°
Motor frame size: 42*42mm -
Nope, they are 200 step motors. Would need to know the number of teeth on your pulleys to know the steps per mm, but if the old motors were also 1.8degree/ 200 step motors it would be the same.
Can you post your homing files as well?

I just changed the pulley's to 20 teeth. Here are the home files, thanks again for the help!

How far can you move the X and Y axes, and does Duet Web Control say they have moved those distances or different distances?

@dgdgdgdg said in Wierd issues:
its all relative to where I the printer head is when I hit home. I can move from there but not beyond. I thought when it homes, that it was supposed to go to the endstops? All it does is move a few mm's in each direction and then the homing is complete and then it says head position is at x 0.0 y 0.0 and z 2.5, no matter where the head is actually located...I am sure its something I am doing wrong but its frustrating to say the least lol
-
I suspect your endstop switches are reading in reverse. Test them, see https://duet3d.dozuki.com/Wiki/Connecting_endstop_switches#Section_Test_endstop_switches.
-
Okay I fixed that, now when it homes It goes to the end stops, but should the endstops be 0,0,0? or do I need 0,0,0 to be the front left corner (when looking at printer) of my build plate? and if so can I fix that by just measuring how far away the end stop is from the bed?
-
It's easiest if you make (0,0) either the front left corner of the bed or the centre of the bed. You are homing to axis minima, so it is the X and Y values in the M208 S1 command that define what the axis positions are when the endstop switches are triggered.

Thank you, I think I have it figured out now, trying out a test print
