@Ce72 Just to eliminate it as a possibility can you turn of Pressure Advance to see if there is any effect.

When I use higher temp materials I add insulating panels to the sides of my printer. But 18C is pretty cool. You probably want to add an insulated cover too.

Nothing expensive. I just use foamcore boards cut to size.

There was an issue with cracked drive gears or rusting on the Hemera a long time ago. Might be worth having a peek to see if that could be causing your intermittent retraction issues.

@bernardomattiucci
It is surprising that 1mm of retraction is too much. At least it is working now.

You can upload your files from your computer to the Duet 2 Wifi over your network using Duet Web Control. It takes a few seconds then the entire file will be on the Duet microSD card. No need for the computer after that.

The Duet 2 Wifi can take up to a 32GB micro SDHC card. Plenty of room for lots of files.

It is possible to uninstall copilot. Do a search for 'How to uninstall copilot'. The most annoying piece of software MicroSponge has ever released.

@Notepad

I had a Hemera + Volcano and used 0.6mm of retraction. 1.0 mm is not a lot and I don't think it would cause issues. Maybe heat is creeping up from the Super Volcano over time. If that is the case you need to improve cooling.

@Triet Oops! Yes the zip file. Glad I could help.

@Triet You also need to update WifiServer.bin and DuetWebControl-SD.bin.

@fcwilt

Modix printers use Duet Controllers.

@Exerqtor I had what may be the same issue. I added 0.15mm to Deretraction Extra Length. I am using PrusaSlicer.

I wasted a lot of time trying to fix the issue with PA, retraction, acceleration, jerk changes. Nothing seemed to work.

I hope this is your issue as well.

In PrusaSlicer the setting is in Printers>Extruder 1>Retraction>Deretraction extra length.

@MurphDurtay if it helps here are my settings but not a V2:
Duet 2 Wifi, Bondtech LGX Lite, E3DV6 hotend, 0.4mm NozzleX.

M584 E3;
M350 E16 I1;
M906 E400;
M92 E568.3 ; (eSun PLA+)
M566 E8000.00;
M203 E6000.00;
M201 E5000.00;

Your current is way too high. The Bondtech specs state 550-650 mA.

@DaveA
Yes. I have two printers running Duet2 boards stand alone. The latest release is working very well.

I have not come across any issues as yet. Just make sure you use the latest version.

@dc42
Duet2Wifi print completed after 1 hour 46 minutes without issues.
Thanks for the fix.

@dc42 Testing 3.6.0-alpha.5 on my Duet2Wifi Ender 5 Plus using the same gcode that failed before. Also using DWC 3.6.0-alpha.2+1.

Just passed 40 minutes with no issues.

@dc42 Duet 2 Wifi on an Ender 5 plus stopped with the code 3 error. Your 38 minute mark sounds about right but I don't have an exact time when it stopped.

I installed 3.5.3 rc1 and ran the same gcode without issues.

@vbtalent2
The outer rings are looking much better. Measure them with a micrometer so there is no guesswork going on. Be careful to avoid any bumps so you don't get a false reading.

If you set 0.2mm as your first layer in the slicer then your printer should be putting down a 0.2mm first layer. That is the ideal situation you are aiming for.

@vbtalent2
Something still not quite right with the layer height. It looks too thick to me but if it is still too far away from the bed then you are extruding too much.

If Cura is not set right as far as filament diameter goes I recommend moving to PrusaSlicer. I think that would be a better beginner slicer.

I use multiple nozzle sizes on my printers but I always set the first layer to 0.2mm no matter what layer height I use for the print.

If your layer height is 0.2mm then 0.02mm would be a reasonable baby step height.

Don't worry about artifacts until you get the first layer right.

@vbtalent2 Please check that the thickness of the paper is what you expect. Due to post apocalyptic skimpflation all papers I have measured are significantly thinner than they used to be. HP premium was 0.2mm but not anymore.

Having written that it looks like your nozzle is too far from the bed not too close. Recheck the nozzle height for the first layer.

Make sure the part cooling fan is completely off for the first layer too.

@carlinicompetizione

I am wondering if commas and decimals are interchangeable in config.g.

Your M566 uses commas and the rest use decimals.

@carlinicompetizione said in Problems from the second layer to the 7th layer:

M566 X500,00 Y500,00 Z300,00 E1200,00 ; definir alterações instantâneas máximas de velocidade (mm/min)
M203 X3000.00 Y3000.00 Z1000.00 E1200.00 ; definir velocidades máximas (mm/min)
M201 X500.00 Y500.00 Z250.00 E1200.00 ; definir acelerações (mm/s^2)

@Arminas These look like Very Fine Artifacts (VFA's). That is the magic name to search for in the forum.

Lots of work has been done on this. Personally I think it is the steppers. I have Creality printers with Duet2Wifi controllers powered by Meanwell power supplies.

I changed every single component but the frames trying to solve this. I changed pulleys, belts, bearings, wheels and wheel bearings. Changed all multiple times with no effect. All are Gates or OpenBuilds now. I changed hotends several times and extruders as well with no real change noticed. Now using Bondtech LGX Pro Lite with Revo6. Prior to that it was Hemera with Volcano.

After you spend enough money on a problem you start to see very minor improvements in print quality but that may be from looking through tears in my eyes.

I finally changed all steppers for E3D units and the VFAs are completely gone.

I have kept up the Duet firmware and DWC versions to the latest. It is possible that that has had an effect. If so, don't tell me, I don't want to know!

M106 P1 S1 H1 T45 ; Set fan 1 value. Thermostatic control is turned on at 45°C

Set S1 to S0.0?
