Issues with my Duet Maestro or bad config?
-
Hi, I'm having issues with my Duet Maestro and I don't know if my board is bad or my config is bad. I was hoping someone could help.
So this will be relatively long so apologise in advance. I bought a Duet Maestro a while back to fit to a heavily modified Anet A8, as most people im sure know the A8 has historically bad electronics, the board was the last thing i wanted to upgrade so i figured a well made Duet would be just the ticket. Unfortunately when i upgraded my prints went from looking like this
to this
At the same time I upgraded to the Duet I also made some other minor tweaks to the mechanics of the printer and figured I had introduced some z wobble somewhere.
Eventually I got so fed up of trying to chase down the z wobble i decided just to go the whole hog and move over to core XY, I bought a two trees sapphire plus, fit a genuine e3d v6 to it and booted it up (with the original control board) it produced this
not too bad so i started the process of moving the duet onto it and this is where i started to get a bit worried i may have, and always have had a bad board because the first benchy came out like this.
now I stopped it half way through and it was on a raft that did not separate correctly however you can plainly see it has the same Z artefact.It is almost exactly that same as before
.This happens with multiple filaments so it is not that, those models did not even come off the same spool. Other than the Duet there is not a single common component between the two printers, it has a completely fresh config on the Duet and it is running the latest firmware.
Really this leaves me two possible problems as far as i can see, my config is wrong and i set it up incorrectly the same way on both printers, or the Duet is bad. I would really appreciate some guidance before the whole thing gets thrown out of the window! I will put my config below.
(note the comments may be incorrect as i have been tweaking to try and resolve the issue)

I'd take another look at these settings.

M566 X600.00 Y600.00 Z60.00 E420.00 ; set maximum instantaneous speed changes (mm/min) M203 X18000.00 Y18000.00 Z360.00 E1500.00 ; set maximum speeds (mm/min) M201 X2000.00 Y2000.00 Z300.00 E10000.00 ; set accelerations (mm/s^2) M906 X900 Y900 Z900 E900 I50 ; set motor currents (mA) and motor idle factor in per centAnd your thermistor settings also need looking at as that isn't correct for an E3D V6.
-
Thanks @Rushmere3D i will give that a go, i think if the thermistor is wrong that could definitely cause weird Z issues. I think the motor settings are less likely simply because i have tried various different things like currents between 50 and 80% of the rating etc etc with no improvement but i shall give your settings ago and see it if helps.
Cheers,

This is the correct info for a E3D V6

@Rushmere3D Yes thanks i looked it up
just running a PID tune on the heater again now then going to try the benchy again. Fingers crossed thats all it was -
Unfortunately those changes have done very little to resolve the issue.
As you can see its pretty much the same as before. The new one is on top.
-
Hi, can you post the text from you're current config.g into the code function ( </> ).
And also what slicer are you using, what temps, speeds are you using? and maybe also upload the .gcode file of the benchy for us to look at.
Thanks.
-
Sure I have pasted the current config.g below and tidied it up a bit. I am 100% certain it is not slicing, filament, temps or speeds though. As stated at the start this has produced the exact same error on two completely different printers with no common parts other than the Duet, both a cartesian and coreXY, multiple filaments and across multiple slicers and did not happen with those same slicer settings and filaments before the Duet was added to either machine. I have had both of the machine producing good quality prints before the duet was added and have been 3d printing for years now so i have a good grasp of slicers, filaments and temps. Which is why this can only be either an error with the Duet its self or an error with my config on the Duet everything else has been proven working.

you forgot drive 4.
also do not enable stealthchop on the extruder.also the hybrid switching gets more problematic at higher speeds
and i dont think the H parameter is supported on the tmc2224
try this
M569 P0 V10 ; Stealthchop2 till about 150 mm/sec
M569 P1 V10 ; Stealthchop2 till about 150 mm/sec
M569 P2 V10 ; Stealthchop2 till about 150 mm/sec
M569 P3 D2 ; Extruder in Spreadcyle
M569 P4 V10 ; Stealthchop2 till about 150 mm/sec -
@Veti Cheers, I will try that, I did not notice I forgot to add drive 4 when I setup the independent Z motors and I will disable stealthchop on the extruder and give it a go. I don't see how changing the V param to increase the speed and which is changes to speadcycle is going to help though? unless I'm missing something which is entirely possible.
-
the switching to spreadcycle at higher speed can cause problem. even layer shifts.
so its best to either leave the default very low switchover or use a high one that does not cause a switchover -
Thanks all for the help so far, the last changes got me some progress, not perfect but enough to give me hope that all is not lost
top picture is the most recent print in both images, exact same gcode file.
banding has definitely gone down and the surfaces are much improved, its is still by no means what I would consider good though.

@jbirley I have to ask... is this a genuine Duet3D Maestro, or a clone board? I’ve seen people have issues with clone boards. Also, can you post the (presumably) Marlin config the printer had before. What version of RRF? Send M115 and post response. Have you tried the default stealthchop/spreadcycle settings, ie remove M569 H and V parameters? Having the change at high speed will produce an audible clunk, and as @Veti points out, a loss of position. I don’t think I’ve ever needed to mess with the default setting on a Maestro.

@droftarts Hi, yes genuine Duet Maestro board bought through ooznest UK, genuine v6 hotend (copper block, titanium heatbreak, 0.4mm nozzle X). Printer ships with a makerbase robin nano which was running what i believe to be a modified version of Marlin but I don't have a copy of it. Running latest version of firmware (m115 output: FIRMWARE_NAME: RepRapFirmware for Duet 2 Maestro FIRMWARE_VERSION: 3.2 ELECTRONICS: Duet Maestro 1.0 FIRMWARE_DATE: 2021-01-05) but also had the same issues when running RRF2.
I have tried the defaults straight out of the config tool with regards to stealthchop. However its a corexy with linear rails and a V6 on a bowden, its moving very little weight around so there is no reason that it should not be able to cope in stealthchop at the 60mm/s i'm printing at and since the printer is about 1m from my desk it needs be as quiet as possible which is why i bought the duet.
I have had this board on two machines now with no common components across them other than the duet, they both printed fine without it but produce the same artefacts with it, so that rules out any mechanical issues. So that leaves me with electronics, config, or slicing i guess. Starting to pull my hair out now.
-
I have just forced all the motors to spreadcycle and trying a test print now.
-
@jbirley have you checked what the accel/speed/jerk settings were on either of the Marlin boards to compare? Just plug the boards in via USB and use YAT to see what they report to M205 etc. Would at least let you compare apples to apples!
-
@droftarts That is a good shout i will do that
-
Unfortunately forcing the motors to spreadcycle did very little.
The cube on the right was printed with stealthchop, the cube on the left with the motors set to spreadcycle with M569 D2. Both printed at 40mm/s including travels.
-
@droftarts previous settings were:
Accel : 1000mm/s XY 100mm/s Z
Speeds: 200mm/s XY 4mm/s Z
Jerk: 15mm/s XY 0.4mm/s Z and 5mm/s Econverting them into mm/min the values are close enough to what was set already.
