Mecanumeric MF2040 LI retrofit (Pantograph)

It's been a while since the last post .  So i've mounted all the machine and today i've done the first work with it , but there is a problem it's mirrored (like the second photo) . So searching online and talking with chatgpt i saw that someone change the sign of the  step_scale and so I did , but than i've problem with the limits . And i have to change them and adapt but i did not figured out yet how to do that properly , so any advice for that is well accepted. Other thing, i've to leave the normal axis gui and change that with one mine personalized because i need custom buttons (and it's more cool) .Can someone give me some advice?

Ok but, when i'm done with the homing , the machine have a problem with the limits. It's convinced that it have the two meters going to the limit homing switch but after the homing it would have to do go to the others side for two meters. Maybe today i figure out how to do that.
