Can you send these commands and report the responses?

M552 S-1 M552 S0 M552 S1 M997 S1 M588 S"*" And then your M587 command to add your SSID.

Another thing to test is to try in AP mode to see if the module is working correctly there or same issues.

@TimsWorkshop said in G32 causing low 4 corners in G29:

G30 P0 X{global.probe_offset_x} + {global.fl_screw_x} Y{global.probe_offset_y} + {global.fl_screw_y} Z-9999 ; Front-Left

I'm pretty sure that the X and Y parameters of G30 refer to the probe position and not the nozzle (so the offset is already being taken into account). You should be able to test this easily to check. I doubt if this is causing the problems you are seeing, but probably best to avoid the confusion.

@timsworkshop said in Could this height map offset be causing first layer issues?:

Thanks @Norder for the help!

very gladly.

Yes, that's exactly how it is... G29 takes the area you defined with M557 and adds or subtracts the offset values ​​of the probe.

I have a 330x330 print bed and leave a 30mm free on the outer edge.
The reason for this is the BLTouch, which is mounted to the left of the nozzle and doesn't quite reach the right edge.
I have two Z-Probes, an IR-Probe from Duet and the BLTouch which I already had before the IR-Probe but didn't want to disassemble it because it has difficulties for some surfaces where the IR-Probe has difficulties such as glass surfaces or PEI and with rough surfaces.

The IR probe is my main sensor so to speak and it would also go to the very edge of the print bed, but because I have an M557 command line that applies to both sensors and because I wanted the mesh to be the same size.

This is what my M557 command line looks like for the 330x330 print bed...
M557 X30:300 Y30:300 P9

For example, if you want to probe the level screws of the print bed in a macro file, like I do to level the print bed "manually" via the level screws, then you have to convert the offset from the BLTouch yourself.

A macro to set one of the three level screws, for example, looks like this.

M561 G29 S2 M291 P"5-fache Messung - Links" R"IR-Probe" T3 G1 Z5 F10000 G1 X29.4 Y142.7 F10000 G30 S-1 K0 H3.162 G1 Z5 F10000 G4 P4000 ; 4 Sekunde Pause G1 Z5 F10000 G1 X29.4 Y142.7 F10000 G30 S-1 K0 H3.162 G1 Z5 F10000 G4 P4000 ; 4 Sekunde Pause G1 Z5 F10000 G1 X29.4 Y142.7 F10000 G30 S-1 K0 H3.162 G1 Z5 F10000 G4 P4000 ; 4 Sekunde Pause G1 Z5 F10000 G1 X29.4 Y142.7 F10000 G30 S-1 K0 H3.162 G1 Z5 F10000 G4 P4000 ; 4 Sekunde Pause G1 Z5 F10000 G1 X29.4 Y142.7 F10000 G30 S-1 K0 H3.162 G1 Z5 F10000

The measured height is shown on the display... if it says 0.082mm, for example, then I have to turn the level screw a little anti-clockwise... the second of five measurements then takes place and I try to get to 0.000, but with +- 0.010 I am more than satisfied because the MeshBedLeveling will come afterwards.

The z-offset entered in the config.g must also be entered in the macro file, so exactly 0.000 is displayed when the nozzle touches the bed.
This makes it easier to concentrate than having to hit the offset of 3,162, which you have to write down so you don't forget it or have to look in the config.g every time.

I find this method of manual leveling better, because here you don't go by feel (0.05mm adjustment sheet or piece of paper as a leveling aid between bed and nozzle) and therefore leveling is more precise and I also find... faster.
I determined the Z offset with a 0.05mm measuring plate by positioning the nozzle 0.05mm above a level screw and then measuring this point 10x with a macro that was written especially for this purpose and where I then got the mean value of these measurements is displayed, which is then the Z offset.

Yeah I know... I'm overdoing the leveling a bit.
But I just enjoy it.
Just a Hobby 🙂

Little explained and much written... also a problem of mine. 😄 (Sorry!)
And the translation makes it look twice as much.

@timsworkshop said in Could this height map offset be causing first layer issues?:

Thanks @Norder for the help!

sehr gerne.

Ja, genau so ist es... G29 nimmt sich den Bereich vor den Du mit M557 definiert hast und addiert oder subtrahiert die Offset Werte der Sonde.

Ich habe ein 330x330 Druckbett und lasse einen 30mm am äußeren Rand frei.
Der Grund dafür ist der BLTouch der links neben der Düse montiert ist und nicht ganz bis an den rechten Rand kommt.
Ich habe zwei Z-Sonden, eine IR-Probe von Duet und den BLTouch den ich bereits vor dem IR-Probe hatte, ihn aber nicht demontieren wollte weil er für manche Oberflächen wo der IR-Probe Schwierigkeiten hat wie zB bei Glas-Oberflächen oder PEI und bei rauen Oberflächen.

Der IR-Probe ist sozusagen mein Haupt Sensor und der würde auch bis an den äußersten Rand des Druckbettes kommen, aber weil ich eine M557 Befehlszeile habe die für beide Sensoren gilt und weil ich das Mesh gleich groß haben wollte.

So sieht meine M557 Kommandozeile für das 330x330 Druckbett aus...
M557 X30:300 Y30:300 P9

Wenn Du zB in einer Makro Datei die Levelschrauben des Druckbettes sondieren möchtest, so wie ich es mache um das Druckbett "manuell" über die Level Schrauben zu leveln, dann musst Du das Offset vom BLTouch selber umrechnen.

Ein Makro um zB eine der drei Levelschraube einzustellen, sieht wie folgt aus.
(Makro siehe oben)

Auf dem Display wird mir die gemessene Höhe angezeigt... steht dort zB 0.082mm dann muss ich die Levelschraube etwas gegen den Uhrzeigersinn drehen... es erfolgt dann die zweite von fünf Messungen und ich versuche auf 0.000 zu kommen, aber mit +- 0.010 bin ich mehr als zufrieden denn es kommt danach ja noch das MeshBedLeveling.

(Screenshot siehe oben)

Den Z-Offset der in der config.g eingetragen ist, muss auch in die Makro Datei eingetragen werden, so wird exakt 0.000 angezeigt wenn die Düse das Bett berührt.
So kann man sich einfacher konzentrieren als wenn man den Offset von 3.162 treffen müsste den man notieren müsste damit man ihn nicht vergisst oder man jedes mal in der config.g nachsehen müsste.

Ich finde diese Methode des manuellen Levelns besser, da hier nicht nach Gefühl (0,05mm Einstellblech oder Stück Papier als Level-Hilfe zwischen Bett und Düse) gegangen wird und somit das leveln exakter und ich finde auch.... schneller geht.
Den Z-Offset habe ich mit einem 0,05mm Messblech ermittelt indem ich die Düse 0,05mm über einer Levelschraube positioniert habe und dann diese Stelle mit einem Makro welches speziell für diesen Zweck geschrieben wurde, 10x gemessen und wo mir dann der Mittelwert dieser Messungen angezeigt wird, was dann der Z-Offset ist.

Ja ich weiß... ich übertreibe es mit dem Leveln ein wenig.
Aber es macht mir halt Spaß.
Hobby eben 🙂

Wenig erklärt und viel geschrieben... auch so ein Problem von mir. 😄 (Entschuldigung !)
Und durch die Übersetzung sieht es gleich doppelt so viel aus.

@timsworkshop said in Help me identify what would be the cause of these artefacts:

The other weird thing is when I put a level on my bed, it is not showing level at all, and if I try to adjust according to the level, then fun a G32, I have to make huge adjustments, which puts me back on a unlevel bed (according to to the level, but not G32)

Please post the contents of the config.g and bed.g files.

In order to understand it correctly, since I don't speak English very well, I use the Google Translator and it translates some texts so cryptically that you have to guess what is meant, and sometimes there are problems with understanding.
That's why I usually post my comments in two languages, so that in case of problems with understanding, a user who speaks both languages ​​can clarify the situation.
It has happened before. 🙂

So you use G32 to get a mesh for the later automatic bed leveling (ABL) after manually leveling the adjustment screws and heating up the print bed ?
And then you have the suspicion that this ABL is not used at all, because the prints don't hold up or, as in the case of the cube, some layers look squashed ?

Please also post which filament you use exactly (brand and name) and also post the temperatures with which you printed this filament.

--- Original Text ---

Poste doch bitte mal den Inhalt der config.g und der bed.g Datei.

Um es richtig zu verstehen, da ich die englische Sprache nicht sooo gut beherrsche, nutze ich den Google Translator und der übersetzt manche Texte so kryptisch das man raten muss was gemeint ist, und es dabei manchmal zu Verständnisproblemen kommt.
Deswegen poste ich meine Kommentare auch meist in zwei Sprachen, damit im Fall von Verständnisproblemen irgend ein User der beide Sprachen beherrscht, die Situation klären kann.
Es ist schon einmal vorgekommen. 🙂

Also Du nutzt G32 um nach dem manuellen Leveln der Einstellschrauben und dem aufheizen des Druckbettes diesen G32 Befehl um ein Mesh zu erhalten für das spätere automatische Bettlevelling (ABL) ?
Und dann hast Du den Verdacht das dieses ABL gar nicht angewandt wird , da die Drucke nicht halten oder wie im Fall des Würfels, manche Layer gequetscht aussehen ?

Poste bitte auch welches Filament Du genau benutzt (Marke und Bezeichnung) und poste auch die Temperaturen mit dem Du dieses Filament gedruckt hast.

@norder Great, write-up mate, thanks for referencing this and I will look into this magnetic shielding... and gives me an excuse to buy some cookies. 😛

@dc42 ahhh, I did see that but didn't think it applied in this situation. Thanks for pointing that out mate

I'm an idiot.... 😰 thanks for the response!

@infidelprops OK, great experiment. So it doesn't seem like it's a wiring issue so far.

Next experiment.........

Start near the middle of the bed and extrude.
Then use G1 X... Y... to (at a low-speed) move in small steps towards the location where you get the extrusion motor error.
See how close you get before getting the error.

Go back and forth to see if it always happens at the same location. Try moving slowly or quickly to see if that makes any difference.

I'm trying to see if there's some electrical interference from the X-Y motors or what.

@infidelprops said in Height Map - Substantial z-offset after setting z-offset:

@fcwilt Just wanted to post a quick update... I ditched the EZABL and put new BLT's in and haven't had a problem since. Prints are coming out beautiful and I haven't had to adjust the baby steps since the first MBL/ABL.

Thanks again for all the insight and help!

I love a happy ending.

I had doubts about the EZABL when I found out it was capacitive. Before you removed it did you ever try a very slow probing speed?

@infidelprops said in DWC and Paneldue connection conflict:

And the file upload looks like a character limit,

the maximum filename length on all modern Duets is currently 120 characters including the path

Thanks @oliof and @droftarts, I'll look into this SBC

You can change to M558 P0 which will use manual probing. It will prompt you to jog the Z axis down whenever it needs to probe.

Just picked up new fuses and put them in... she's alive!

Now to re-do all my cables

@alankilian said in How do you solve filament runout?:

@infidelprops Before I load a spool, I get inside the spool center hole and cut off that little hook with a sharp knife.

It's difficult, but seems to work for me.

Except when I forget which is only on important prints. 😞

Well that sounds stupidly obvious and not sure why I didn't think of that... thanks mate, that is indeed and easy fix and I will look into it! 🙇

@infidelprops

Glad to hear things are looking good.

Just as an FYI, I have not been able to eliminate the seam completely but what you can do is to hide it in plain sight by having the slicer put the seam at a corner. It won't help on a smooth corner like your example but if you have sharp corners it can hide a multitude of sins.

@engikeneer & @Phaedrux - thanks and yes... a way to manual adjust my screws while I wait for my TFTs to arrive because currently I turn them the printer off and adjust as required.. a bit more work, but doable.

Just read the article and that looks like the ticket, thanks. I'll read through that and adjust as neccessary.

@paulhew thanks, I will check that article out!

As for an update... After updating my z steps to 800, from the original 400 and re-calibrating 0, levelling, and new mesh, I just finished the second calibration cube and it came out muuuuuuch better!
cube-y.jpg
Still elephant feet and corners to fix, but at least it's printing decent!

@paulhew Thanks dude and yeah, I've seen that link and have all those configured. I'll keep sussing around with it

@engikeneer thanks mate, that's a really good download of knowledge! I have started to print the bed square level test with the 5 squares, and those print pretty well and as expected, a few better than others.

I did do quite a bit more tweaking and adjust the mesh grid as you suggested and I got a much better height map.

Just finished a level test and the center square was perfect... couldn't ask for a better first layer
