X axis position

[Rudy2A]

Hello, I am having a problem with the position of my X axis.

By default in my Config.g file, it is at -23. Because of this, I can not place the center of my bed and encounter X positions in error.

and when I do a Home, all my settings are 0 except the X.

If I make a G92 X0, then M500, it's ok or there is something else to do thank you.

the minimum position is defined by the
M208
command in the config.g

@Veti said in X axis position:

a position minimum est définie par la
commande
M208 dans config.g

thank you,

If I put a 0 in place of a -23 in; (config.g) Axis Limits
M208 X-23 Y0 Z0 S1

When I do a leveling of my bed, I have a band in my height map (Heightmap.csv) that is not taken into account. That's why I was advised to put -23 in place of 0?

Hi,

If you home in the max direction whatever value is set as max for that axis becomes the position after homing.

Likewise if you home in the min direction whatever value is set as min for that axis becomes the position after homing.

When you do G92 X0 you are telling the machine that the current position, which the min value says is -23, is actually 0. I don't think you want to be doing that. If the physical position is actually X=0 then the min value should be 0.

Assuming the min value of -23 is correct then to obtain X=0 after homing you need to put a G1 X0 command into your homeX.g file.

Also, M500 doesn't work like that. It's not the same as the 8-bit firmware EEPROM save.

With reprap it saves a specific set of values to config-override.g, usually things that are computed by the firmware or measured in an automatic way.
