@jay_s_uk yeah i get that part

@jay_s_uk

im still pretty new to this and the directions are kind of confusing to know what movement is actually - and + ,

this is the railcore starting moves link , when i run these moves the machine moves into the correct positions

x motor

G91
G1 H2 X10 F3000

y motor
G91
G1 H2 Y10 F3000

@fcwilt
do you mean this

M574 X1 S0
M574 Y1 S0
M574 Z0 S0

@fcwilt could you give an example of what the looks like ?

• the x any y files are seperate*

@fcwilt sorry I'm not familiar with the </> format

new railcore and im having an issue with the homing direction, when I run an x and y stepper test with

G91
G1 H2 X10 F3000
&
G91
G1 H2 Y10 F3000

the head moves to the appropriate direction,
however, when I'm homing, the axis is moving in the incorrect direction.

I'm not sure what the correct parameters are to adjust these settings

thinking its the home files .

@bearer just a visual artifact

on vin power the board looks the same

@Phaedrux purchased in august through filastruder, and I went through all these steps3
