finally printing but STILL haven't solved prob of offset heatbed

This problem has plagued me since I first started posting.
The heat bed on my machine is about 10mm from the x min endstop.
What is the most elegant way of having the hotend, after homing,
adjust itself +10 on the x axis?
Do it in marlin? or setup up an offset in slic3r when setting the bed up?

This isn't a current issue with the early prints as everything is just
being printed in the middle of the bed.

Oh, I have a GLCD connected if that makes life easier.


Andrew.
ps, I think I'm going to frame my first print

I have a biased opinion. But my response is you should fix this issue by physically getting the printer to be 'correct'. When you home the printer, you do want to accurately know where the limits are and for simplicity you don't want some weird values for Min and Max travel on the various axis. But what ever you end up with, my vote would be to change values in the Configuration.h file of Marlin and not in the Slicers to finally adjust everything and get it 'correct'.

There are going to be plenty of other things that can go wrong. You really do want to start off with the hardware being well behaved and knowing precisely things like where the limits of travel are.

Find In configuration.h

// Travel limits after homing (units are in mm)

#define X_MIN_POS 0
#define Y_MIN_POS 0
#define Z_MIN_POS 0
#define X_MAX_POS 200
#define Y_MAX_POS 200
#define Z_MAX_POS 200

Change #define X_MIN_POS -10

Then X0 really is at zero, no need at add 10 in anywhere, it fixes itself.

What Dust said,
or you can use the "M206" command from pronterface to overwrite the firmware.

I think the original poster's problem did not involve the Z-Axis. M206 is focused on the Z-Axis and not X or Y.

Hi Roxy

Sorry but your mistaken

[reprap.org]:

M206 Marlin, Sprinter, Smoothie, RepRapFirmware - Set home offset

Parameters
Xnnn X axis offset
Ynnn Y axis offset
Znnn Z axis offset

Yikes!!! Thank You for the correction Dust!

(I see what happened now. I clicked on the M207 link instead of M206 because I wasn't being careful enough. )

thanks for the info.
I tried the (-x,-y,-z) but the problem created by max_lengths being calculated
from -x to +x etc had me concerned what other incorrectly calc'd values were
hiding.

Solved the prob by hot knifing the offending parts of the frame.
