Solved Y offset correction

[PaulHew]

I have a Maestro board running RRF3.

I have tried but cannot fathom it out as G10 is something different now.

I have lost Y axis build area, since I installed a Titan Aero extruder mount.
I know how much Y I have lost, 20mm, but do not know how to tell the Duet how to compensate for it.

Please could someone assist, as I am lost.

TIA

Paul.

Can't you just substract 20mm form your Axis maxima ?

[SIam]

did you mean that your y endstop is now on position -20?
if yes you can set the Axis axis minima Limits with:
M208 Y-20 X0 Z0 S1

Thanks for your replies.
This is my current M208

M208 X0:235 Y0:235 Z0:235 S0                       ; set axis minima:maxima

My bed is still the same size.
X0 is correct, it is Y that is wrong.
When Y is at 0, the nozzle is over the control box of my Ender3, due to the Hangtight mount I am using, it has created an offset.
I have enough travel on the bed to be able to offset this dimensional discrepancy, but as I said, I am not sure how!

So, could I use Y20:255 in the M208 command?

Thanks again,

Paul.

@PaulHew said in Y offset correction:

When Y is at 0, the nozzle is over the control box of my Ender3

This means the nozzle is so 20mm out from the bed (pos. 0) ? or 20 mm to far in the bed?

[PaulHew]

so when Y hits the endstop, that is zero, but the nozzle is off the bed.

Hope that makes sense

ok so you have to move your head 20mm to reach your bed, in this case is the endstop on -20 mm and the bed is 0?

M208 X0:235 Y-20:235 Z0:235 S0                       ; set axis minima:maxima

Thank you, I will try when it has finished printing.

@SIam Thank you, That worked.
Appreciate the help

Kind Regards,
