I tried to paint the glass bed white and apply the capton again. It seems to be working, so I will have all the options.
For a long time I would also like to change the probe, but every time I make a change it takes 5/6 days to fix it well.

The black cardboard under the glass illuminated me. I didn't know about this possibility. Maybe then, abandoning the 4 old targets, but using the new matrix system, it is worth trying again to stay on 1.26.

I would like to know if, given your experience, there is a support that conducts heat like glass, which is removable like glass through clips, with good adhesion. I have seen flexible magnetic plates on the market, but I do not know their effectiveness.

@droftarts I did some tests. By removing the line "M558 P1 H3 F120 T6000" it does not find zero because it DOES NOT turn on the probe.
I have the 4 wire probe.
I'll do more tests, but I'm already thinking about going back to 1.09r .......

@droftarts said in Ormerod2, problem new firmware.:

You should get a preview of the 4-point bed mesh in the DWC.

Thanks, it's very kind of you. I'll definitely do this rehearsal this week. For now I'm going on with some workarounds, but I want to solve for sure.

Unfortunately (or fortunately), it has changed a lot since the old 1.09 from which I come.

Could I still use the glass plate with the new "IR probe Duet3D"? Could you indicate, if possible, a link with explanations for the assembly and use of this probe?

Hi to all,

I'm trying to update the sign of my Ormerod2 to version 1.26 from the old 1.09r.
Having changed too many things, I have a bit of difficulty, but I'm slowly moving forward.
I still have the glass top with the 4 paper targets on the corners with the old IR probe (the original).

I am having difficulty with plan compensation via G29 (new method) and also with G32 (old method).

• G29: I have not understood if with this system I can only test the 4 angles or I must necessarily make a matrix.
  (which is impossible for me with a glass top and 4 corner targets).
• G32: Although my targets are at X 65 and Y 215, in the bed.g that I attach, I have to give much higher coordinates
  for the probe to go over it.

Can you tell me where I'm wrong?
I would not like to go back to 1.09r because it seems to me that the new sign has improved a lot.

Is there anyone who installed this firmware on the ormerod 2?

If so, would you attach your sys files to understand?

Thank you all.
