CoreXY Mirrored prints

hi
i read in here:

this:
Important: make sure that you have chosen a right-hand axis system. That is, looking down on the printer the +Y direction should be 90 degrees anticlockwise from the +X direction. If instead it is 90 degrees clockwise, you have a left-hand axis system, which will give you mirror-image prints.

i have blv cube my y end stop is left and also my x endstop

how can i make that the prints will not be Mirrored
and not change my end stop place

tray switch motors with m584 and change motors direcion
and its start moving to worng side ....

@bookra set the ends stops at the correct end of the axis (minimum or maximum, so that your co-ordinate system is right handed. Se

M574 X1 ....etc = low end
M574 X2 ....etc = high end.

@t3p3tony if i set x to max. instead of min
at 0 it will show 350
there is a way to overcome this?

@bookra

start by ensuring that the motor movement direction and which motor is allocated to "X" and "Y" is such that you have a right hand co-ordinate system for movement. You can do this by manually moving the carriage (slowly) to the middle of the work volume, then send G92 X150 Y150 or similar so that the printer allows movement. Be careful not to send too large moves when jogging the axis. Now job the axis using DWC. Does 10mm in +/-X move in the correct way for a RH system? the same for +/- Y? If this is working correctly then move on to the endstops, if not first sort the motor directions (using M569) and/or allocation (using M584) until this is correct.

Next the endstops. If you have, for example, the y endstop at Ymax, then use Y2 in the M574 command to indicate this endstop is at Y Max. if its at Y min use Y1. Similar for X.
