Ormerod2, problem new firmware.

Mak64

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.

You're setting the probe offset twice, once with M558 and then again with G31. Probe offset with M558 is obsolete after RRF 1.19. This may be the cause of your probing offset problems. Set M558 to M558 P1 H3 F120 T6000

G32 calls the 'bed.g' file, so you can put G29 or G30 commands in that, depending on the method for levelling you want to use. See here if you want to use the older method that you are familiar with: https://duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwareCartesianPrinter#Section_Bed_probing_file

For G29 Mesh compensation, see https://duet3d.dozuki.com/Wiki/Using_mesh_bed_compensation
If you're using targets on the top of the bed, and you don't want to change/update your probe (the IR probe Duet3D sell would be a revelation for you!) set M557 to the four corner points over the targets, with P2 on the end, to probe only 2points in each direction, eg M557 X65:215 Y5:185 P2. The probe offset should be used, so you may need to adjust these points. Run mesh compensation with:

M561 ; clear any bed transform
G29  ; probe the bed and enable compensation

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?

droftarts

@Mak64 Here's a few pages on the IR Probe, though the first is the most comprehensive:
https://miscsolutions.wordpress.com/mini-height-sensor-board/
https://duet3d.dozuki.com/Wiki/IR_Probe
https://duet3d.dozuki.com/Wiki/Connecting_a_Z_probe
The board isn't quite a drop-in replacement for the original IR probe (do you have the 3 or 4-wire version?) but there designs around to print a new carriage to hold it, eg https://reprap.org/forum/read.php?340,636832,page=1

For the bed surface, following dc42's recommendation on his page (first link above), I put a piece of matt black paper under the glass on, which is on top of a red heated bed with white writing which the probe got variable readings from. The IR sensor doesn't like bare aluminium under glass, either. And watch out for (some) LED lights that give off too much IR!

@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 .......

You should use P2 in the M558 command for the Ormerod 2 4-wire probe.

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.

I don't think the black backing will work if you are using the original Ormerod proximity sensor.

You can carry on using the targets if they are in a square and you set the M557 parameters so that the sensor is over the targets when it probes the 4 points.

droftarts

@Mak64 as @dc42 says, your probe setting in config.g should be:

M558 P2 H3 F120 T6000                   ; set Z probe type to modulated and the dive height + speeds

Sorry, I assumed you had the 'original' 3-wire version!

I'm not sure paper/card underneath the glass works with the RepRapPro modulated probe, as I seem to remember it had a very close range, so paper under the glass was too far away to probe. White was the only colour that really worked with it, too. But dc's IR probe works well with black surfaces, including those like BuildTak, and the probe distance means it can work under glass or on a surface. Works through Kapton tape, too. The flexible magnetic sheets are generally fine too, but best with no writing on (plain black).

However, the glass on the RRP bed holds the bed (mostly) flat, as the aluminium is there as a heat spreader and too thin to provide a stable flat surface. Without the glass the bed may be less flat. You may need to replace the aluminium sheet with a piece that is properly flat. I'd stick with the glass, put black paper under it, and replace the probe.

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.
