mini ir on duet2 wifi

andnosobabin

Hello everyone,

I'm struggling with setting up my duet2 wifi with a mini ir sensor. I have it hooked up right (it flashes when I move a piece of paper or anything up to it) but I'm stuck at the m558 commands. When I send m558 p1 it returns:
Error: m558: missing z probe pin names

My config.g file under z probe says:
M558 p1 c"zprobe.in" h5 f120 t6000
G31 p500 x0 y0 z.25
M557 x15:195 y15:195 s20

What am I missing lol

Thanks everyone!

Ohh and what will I need to do to map the bed to the sensor location?

Phaedrux

Can you copy and paste the full config.g here?

Can you also send M122 and M98 P"config.g" and post the results?

Error: in file macro line 63 column 13: M106: expected number after 'H'```

The error on line 63 is due to me not having a fan configured yet and I haven't yet messed around with it. Im still waiting on a blower pump for an external parts cooler fan mod.

Thanks for your help!

the m558 commands. When I send m558 p1 it returns:
Error: m558: missing z probe pin names

When are you sending M558 P1? Why would you send that by itself anyway?

The commands in your config seem correct and produce no errors.

Have you tested the probe yet?

@phaedrux TBH I'm not sure what i was thinking when i sent that. I couldn't find a good guide and was jumping around and overthinking things i think. Im pretty sure the board works but im waiting on a magnetic bed instead of a pei sheet on an old ender glass plate.

When i put a sheet of paper on the bed tho and raise that to the sensor the light goes out. Does that mean its working?

Im still trying to figure out how to map the sensor to the bed too.

Thanks for your reply

@andnosobabin said in mini ir on duet2 wifi:

Easiest way to check is to use the static test described in the link above.

andnosobabin

@phaedrux OK I just got time to test things. Everything is working except when i run G29 i get the error: Probe already triggered before probing move started. I set the offset and everything in the link. The trigger height was 6.14 but it triggers well above that as well. like there are 2 trigger zones. Im using a flex steel sheet coated in textured pei but it happens with a sheet of paper too.

Phaedrux

Are you using M558 P1 or M558 P8?

andnosobabin

@phaedrux M558 P1 C"zprobe.in" H5 F120 T6000

Phaedrux

Can you try P8 instead?

andnosobabin

@phaedrux Sorry for being almost a year old and reviving this post, life took over and I couldn't get around to working on this till now.

I got it working kinda 1 time. I could run G32 and G29 commands and it would probe the bed as expected but the height map was way off. I tried going back through everything I did (changing nothing) and now it wont even probe the bed it just raises and then crashes the nozzle into the bed ignoring my limit switch and gives me an error that the probe wasn't triggered during the move.

Here's the Z probe section from the config.g file

; Z-Probe
M558 P8 C"zprobe.in" H5 F120 T6000              
M557 X30:215 Y15:195 S20                       ; define mesh grid
G31 p500 X30 Y0 Z3.562

Oh and I reran the M122 and M98 commands you said back in Jan and there were no errors shown.

Thanks Again

Go through this guide to test your probe.

This is the reverse of what should happen, if you are using Duet3D/dc42s IR probe. What probe is this? The LED should be off when far from the bed, and light up when something is close. Also in DWC the probe value should be 0 with nothing under it and 1000 when triggered.

Check your wiring (though I’m not sure how it would work with incorrect wiring), see https://docs.duet3d.com/User_manual/Connecting_hardware/Z_probe_connecting#mini-differential-ir-sensor-by-dc42. If the probe isn’t the Duet3D probe, it might be that you need to invert the probe signal, by putting ! in the pin name, ie
M558 P8 C"!zprobe.in" H5 F120 T6000

The following statement also does not match the IR probe of dc42...

@andnosobabin said in [mini ir on duet2 wifi]
... (it blinks when I move a piece of paper or anything on it)

The dc42 IR-Probe does not "blink".

@andnosobabin
Can you post photos of the IR-Probe and its wiring on the Duet-Wifi ?

andnosobabin

@phaedrux If i raise nozzle up 5 or 10mm and run the G30 S-1 command and run it it says "Error: Probe already triggered at start of probing move" if i go 20mm it runs but then triggers at 15mm above the bed and if i run G32 it probes the bed and returns:

"Warning: the height map has a substantial Z offset. Suggest use Z-probe to establish Z=0 datum, then re-probe the mesh.
110 points probed, min error 2.122, max error 3.172, mean 2.710, deviation 0.228
Height map saved to file 0:/sys/heightmap.csv"

I re ran G92 Z0 and still the same issue. When i first picked this back up the other day I did all of this and it worked but the next day nothing worked

andnosobabin

@droftarts I don't remember what was going on back then its not acting that way now tho it just wont trigger at a low height to calibrate it.

andnosobabin

@norder I dont remember what was going on back then its not doing that now tho. I appreciate the quick reply tho!

It looks very much like the probe is mounted too low on the print head.
15mm too deep it seems, which can't be the case with a Duet IR probe from dc42 as it's meant to be fitted to the printhead at just 1.5mm above the print bed when the nozzle touches the print bed.

However, we still do not know if the probe is really a Duet3D IR-Probe from dc42.
A photo of the probe and how it is mounted on the print head would therefore be of great help in order to be able to help you further with your problem.
At the moment there is not enough information to be able to provide specific help.

When we read about a Mini IR here, in most cases we are talking about the dc42 IR, but what you write here does not fit the dc42 IR.

Google Translate
-- Original Text --

Es sieht sehr danach aus, als wäre die Sonde zu tief am Druckkopf montiert.
15mm zu tief, so wie es scheint, was bei einer Duet IR-Probe von dc42 aber nicht der Fall sein kann, da sie mit nur 1,5mm über dem Druckbett an dem Druckkopf angebracht werden soll, wenn die Düse das Druckbett berührt.

Wir wissen aber immer noch nicht ob es sich bei der Sonde wirklich um eine Duet3D IR-Probe von dc42 handelt.
Ein Foto der Sonde und wie sie am Druckkopf montiert ist, wäre daher eine große Hilfe um Dir bei Deinem Problem weiter helfen zu können.
Momentan reichen die Informationen nicht aus um gezielt helfen zu können.

Wenn wir hier von einer Mini IR lesen, ist in den meisten Fällen von der dc42 IR die Rede, aber dass was Du hier schreibst, passt nicht zu der dc42 IR.

andnosobabin

@norder The sensor is mounted 1.5mm above the bed and the wiring seems to be correct as the sensor DOES function properly but I seem to not have the correct settings and it isnt behaving as i think it should. I will attach pictures to confirm this for you tho.
P.S. The capacitor is oriented differently because i moved it as it was in the way of a previous printhead not the current one.

Thanks for your assistance!!
