Not sure if worth mentioning, but I have it set as client mode.
I did try with AP mode, but same problem persisted.

@jay_s_uk - thanks mate. I did some backwards looking through previous releases, and found the most recent wifi version update, so I'm now on 1.27. Good shout.

I've gone back and did the following, which shows my network, but with an IP of 0.0.0.0

>>> M552 S0
SENDING:M552 S0
Error: WiFi module reported: no known networks found
[ERROR] Error: WiFi module reported: no known networks found

WiFi module is idle
>>> M587
SENDING:M587
Remembered networks:
TNCAPF2FD81 IP=192.168.1.14 GW=0.0.0.0 NM=0.0.0.0
SKYNET IP=0.0.0.0 GW=0.0.0.0 NM=0.0.0.0

So seeing this, I then decided to clear the list with M588 S"*".
I then M552 S0 and then re-added my network with M587.... but I still can't connect.

Very weird behaviour

Hi all!

So my SD card slot stopped working out of nowhere and I am in the process of putting in a replacement board.
I've upgraded the firmware from 3.1.1 -> 3.3 -> 3.4.6 and in all of these instances, I cannot get my WiFi access to work as every time I try to set my network details with M587, I get errors stating SPI Timout.

Here's my M587 command

>>> M587 S"Skynet" P"******"
SENDING:M587 S"SKYNET" P"*******"
Error: M587: Failed to add SSID to remembered list: SPI timeout
[ERROR] Error: M587: Failed to add SSID to remembered list: SPI timeout

Once this happens, I did try turning the WiFi module off and back on, but got the same result.
I've tried re-installing the firmware, but still the same SPI error.
I read on an old Git issue that sometimes M587 will not work the first time, but the second time it always does, and so I tried that, but after the first failed M587, the WiFi module turns off:

>>> M552 S0
SENDING:M552 S0
Error: WiFi module reported: no known networks found
[ERROR] Error: WiFi module reported: no known networks found

WiFi module is idle
>>> M552 S1
SENDING:M552 S1
Error: WiFi module reported: no known networks found
[ERROR] Error: WiFi module reported: no known networks found

Error: M587: Failed to add SSID to remembered list: WiFi module is disabled
[ERROR] Error: M587: Failed to add SSID to remembered list: WiFi module is disabled

I do see that 3.4.6 does not have a Duet2_SDIAP32_WiFiEth.bin, but 3.4.5 does and this is the one I used... Unsure if that's an issue?

And below is the output of M122, I do see that my WiFi version is 1.02 - is that the most recent?

Thanks for reading!

Thanks @gnydick - Definitely a few things for me to tweak and after further reading of the documentation, the 3 points are levelling off the first point so I believe that is why those 4 probe points are all similar but the bed is more center.

Once this print finishes, going to spend some time getting that first point flush with the rest of the bed by loosening the knobs and running smaller G29 probes to get it more aligned and then once I'm happy, going to run another P20 mesh and see how we go.

Hi All,

I've been doing some tweaks on my printer as my 4 lead screws just weren't holding and was causing me to set Z0, probe offset and MBL/ABL before every print. So I removed the springs and put on silicon brackets which keep it nice and tight.

I was able to adjust everything so that when I run G32, I get either 0.00 or 0.001 deviation which is great for the next G29 run. BUT, when I run G29, my 4 corners are all visually lower which I find odd, especially of G32 is telling me these are all level.

So after a few attempts to MBL and ABL and getting the same result in my Heightmap, I wanted to see if I could get some suggestions from here.

I have a Ender 5 Plus with 4 bed screws and 2 Z lead screws on independent motors.
Duet 2 Wifi
RepRap version 3.4.1

Here are some screenshots from my Heightmap:

And this my bed.g file

Looks like my assumption was right, I just did the change and it probed all my points and gave me a good mesh.
So happy to finally have my height map back where it belongs.

Going to add some comments and notes to mesh to automated the calculations in the future.

Thanks @Norder for the help!

undefined

@norder agreed!

So now I've done the change and I can see my mesh is centered, but I have had to rejig a lot of my bed.g and mesh.g files to accommodate.

I'm getting points get be reached when I run G29, and I believe if I remember correctly, G29 takes into account the offsets and and does calculations itself?

So if I have:

; BL-Touch Probe Offsets
global probe_offset_x		 = -30		  ; BL Touch X offset
global probe_offset_y		 = -36		  ; BL Touch Y offset 
global probe_offset_z		 = 3.906	  ; BL Touch Z offset

Then in my mesh.g I have, as this is the true area I want to probe:

M557 X58:378 Y73:378 P20

But when I run it, it looks like it's adding my offsets, so my question is do I need to subtract these offsets from my x/y coordinate in my mesh.g to allow G29 to properly calculate?

undefined

@norder ahh man, I feel really dumb! Yes, my BLT is in front, and to the left of the nozzle and not sure why I didn't pick that up. I've updated that and my mesh.g file and will do some calibration again.

And nice pick up on the EZABL reference, I did have one but put the BLT back on and forgot to update the comment.

Hi All - I've been trying to print some fairly large pieces, and no matter what I do, I can't get a good first layer on the outter extremities and starting to wonder if this height map offset is the issue?

Now I'm not sure why my height map shows like this, and would love to resolve it, but here's how it looks now:

Bottom Right, Top Right, & Top Left are all 'outside' the print bed, and my print area is in inside the red box.

I've done G32 and G29 multiple times, and even though on G32, I can get a 0.00 - 0.001 across all four corners, I do not get even first layer in these corners and can visually see the height difference when printing.

I'm sure there's some wrong config, somewhere, causing this and it's probably has to do with my mesh.g file alongside my probe offsets (Hemera hotend with BLT), but if I reduce my mesh size prob points, I get unable to reach probe area and failures.

Would love some help on getting my config correct, as well as the height map as pictured correct, so I can run more G32/29 bed levelling to hopefully get consistent first layers in these outter areas.

Here's some config files for reference:

@rexx Thanks mate. This is my fan shroud and I think my hemera setup is sagging on the left as no matter what I do, I cannot get this left hand side more green than blue.

I previously had a Microswiss and could get pretty level meshes, but with this Hemera, my left side is always sagging down.

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)

undefined

@rexx Yeah, I started using rafts more to reduce the elephants foot and it has helped a lot. I use PrusaSlicer and do have elephants compensation at .2 for my .04 nozzle, but still see this problem.

It may very well be cooling and I am looking for alternative part cooling shrouds for my Hemera.

undefined

Thanks everyone for the suggestions! I've done some tweaking on the pressure advance, flow, steps etc. and it does look a lot better. I still get some bulging on these bottom edges, but on other test prints I get near perfect prints.

For the slicer question, I use PrusaSlicer and it seems to do pretty well.

undefined

Hi all.. I'm doing some printer calibration and noticed on my XYZ cube, I get these odd artefacts on the edges, at inconsistent areas.

It looks like it's too hot and melting, or possibly over-extrusion? But I've just calibrated my e-steps and tested the feed 3x times and it's spot on now, but then I get this so I'm unsure.

Can someone suggest some possible causes of this so I can investigate?

Thanks!

undefined

@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.

undefined

@droftarts hahaha! Yes, I do love my Stargate!

And thanks for the tips! I've got a E3D Hemera with a small 4010 fan on the side, and probe on the front left, so the fan and carriage being on the left (where the blue lines hang) could definitely be an issue I haven't considered.

The area I'd love to fix, is how off the visual of my Height Map is, from my Print Bed. Is this fixable or because of my mesh.g settings, I just have to live with this?

undefined

Hey all, been a while and I hope everyone is doing well!

I wanted to see if I could get some help to correct my Height Map visual in my DWC panel

I think this is because of my axis offsets due to my fan and hemera setup, but not entirely sure. I do know that my corners print better than my centre and even after fixing z-offset, z-probe trigger, and baby stepping, my centre is still still printing too high compared to my outer regions and thought it's time I try to fix this.

Board: Duet 2 WiFi (2WiFi)
Firmware: RepRapFirmware for Duet 2 WiFi/Ethernet 3.4.1 (2022-06-01)
Duet WiFi Server Version: 1.26

Here's a few excerpts from my config.g file:

BL-Touch Probe Offsets

global probe_offset_x		 = 30		  ; BL Touch X offset
global probe_offset_y		 = 36		  ; BL Touch Y offset 
global probe_offset_z		 = 3.585	  ; BL Touch Z offset

Axis Min/Max

M208 S0 X355 Y355 Z400                             ; set axis maxima

This is from my mesg.g file, where I reckon the problem lies, but when I previously tried to fix these, I wouldn't be able to run a 20pt G29 as it couldn't reach areas.

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

undefined

@phaedrux Thanks mate. I'm trying first the assisted bed levelling so I can adjust the bed knobs, and then I will go and get my G29 and mesh.

I just sent M671 and it says lead screws are not configured... I've put it in my config.g file towards the bottom of the file, and M671 still reports no leadscrews.

But what's interesting is I just replaced my variables with the actual values, and M671 now reports leadscrew coordinates configured.

;M671 X{global.fl_screw_x}:{global.fr_screw_x}:{global.bl_screw_x}:{global.br_screw_x} Y{global.fl_screw_y}:{global.fr_screw_y}:{global.bl_screw_y}:{global.br_screw_y}
M671 X30:310:30:310 Y76.8:76.8:338:338

And now when I run G32, I get readings back to adjust the knobs. Is this a known feature where this Gcode doesn't accept variables?

undefined

@fcwilt That's a bit weird... On my other Ender 5 printer, same setup as this one (but with different offsets/axis) and with that I am able to do a G32
