…Hi,
first steps with my voron 2.4 350.
I have set up the steppers , everything works fine, homing, pid tunning and so on BUT, the cartesian origin are in the back right instead of front left.
I don’t undertsnd how to set up the config to tell klipper the origin is front left.

If i use :

position_endstop: 0

position_max: 350

homing is doing good, taking limit switches in back and right and set up the origin back right.

If I use :
position_endstop: 350

position_max: 350

homing is going on the left and do not find the limit switch.

Is there anyway to make me understand how to speak to klipper I’m a sttoopid guy but I want him to put the origin where I want it to be :smiley: ?

thanks in advance :slight_smile:

I have already but this doesn t explain how to set up correctly the origin.

Only thing i could have done is to reverse the dir_pin. it worked but messed up the quad gantry level macro.

Also it’s not explained how to make a homing toward max_pos or min_pos :confused: I think it’s probable obvious but i’m a rookie in klipper..

You have to properly declare your steppers and where the endstops are located:

For non standard definitions you can play with the parameter homing_positive_dir.

For QGL it is essential to follow the correct motor order and joint and probing points definition.

You can of course check the config files of similar printers to see how others did it of you won’t succeed with the documentation.

Hi, I have finaly resolved the problem.
Motors assignation was… wrong !
X and X2 were affected at the back X1 and X3 at front…

Thank you for your help and your fast answers :slight_smile:
