M208 Axis Limits confusion

Royce

And another question for you guys
In my config.g, I set the following:

; Axis Limits
M208 X0 Y0 Z0 S1                      ; Set axis minima
M208 X300 Y300 Z300 S0                ; Set axis maxima

Unfortunately, I don't get the high-end / low-end scheme 100%
My endstops are positioned (seen from the top-front of the printer) left for X and on the back for Y.

How would I need to set the M208 values to have 0/0 in the front left corner?
Thanks for any help to guide me!

What you have is correct. You also need to tell the firmware which way the X and Y axis motors move in the M569 commands for the X and Y motor drivers, and whether the X and Y endstops are at the low (zero) or high (300) ends of the axes.

@dc42
Thanks for the reply.
I have set them as follows:

M569 P0 S0                            ; Drive 0 goes forwards
M569 P1 S0                            ; Drive 1 goes forwards
M569 P2 S1                            ; Drive 2 goes forwards
M569 P3 S0                            ; Drive 3 goes backwards

What would I have to do to achieve my goal to have 0/0 in the front left corner?

I found the culprit.
Y Endstop was set to the low end instead of high end.
Thank you all

~~@Royce How do you specify if an end-stop is at the low-end or the high-end?~~

M574, sorry didn't check good enough...
