Probably, so I just removed the daemon.g completely and its running fine.
When I get time I'll try to find why the G4 S1 is causing a pause instead of just reloading macro, its also recommended in the documentation to have such a command.

Recent upgrades to my printer, but same board and firmware as previous.

Slicer is Superslicer Version: 2.4.58.5, which I used prior also with no issues.

Doing parts now I get blobs and zits on my part, even in vase mode
I can watch it in vase mode with no layer changes or retractions and it pauses/stutters whenever it's doing arcs or circles.

Issue is very similar to https://youtu.be/Hvw3DrVAeTA

edit :
https://youtu.be/ZM1MYbsC5Aw
this is the same problem, and zits on parts, except I have power recovery off so his solution does not work.
I also reduced resolution to 0.5mm in slicer, so that round egg shape is now low poly looking, but same problem,

Is there a setting with RRF that helps this situation or is this purely slicer based ?

System:
Board: Duet 2 WiFi (2WiFi)
Firmware: RepRapFirmware for Duet 2 WiFi/Ethernet 3.4.3+ (2022-10-06)
Duet WiFi Server Version: 1.27

Edit 2: Turns out to be related to daemon.g
When I did my upgrades I added neopixels to printhead which change based on different input status.
Have not figured out just what in the macros was causing the pauses.
Daemon was only 2 lines G4 1 , and a P98 to run the led macro.

@jay_s_uk

That was it !
Thanks for pointing me to it.

@Phaedrux

M122 shows the firmware is 3.4.3 but does not show the wifi version. I only have paneldue to connect and it doesnt seem to show all the info

Duet 2 wifi
was on 3.3, with wifi server 1.26 and DWC 3.3.0

updated by uploading Duet2and3Firmware-3.4.3.zip in DWC, let it upload, pressed yes to update firmware, and after it uploaded, updated, and rebooted it no longer can connect.

Through paneldue i can see its upgraded to 3.4.3
it connects to wifi and gives me an ip address, i can ping the ip address.
i cannot access DWC via name.local or via IP address.
I have removed SD card, deleted www folder and replaced with the contents of DuetWebControl-SD.zip

Still cannot connect to DWC on multiple bowsers tried.

Any suggestions ?

in the patch notes it states :
"If you configure a Z probe using multiple M558 commands instead of a single one, you must make sure that only the first one has a P parameter. This is because M558 with a P parameter now sets default values before processing the other parameters of the M558 command."

My Config file has the following. :

; Z probes
M558 K0 P8 C"^zprobe.in" T18000 A5 H5 R0.2 S0.01 F600 B1 ;
G31 K0 P500 X0 Y25 Z2.557 ; inductive probe offset,

M558 K1 P8 C"^zstop" T18000 H5 R0.2 S0.005 F120 A10 B0 ;
G31 K1 P500 X0 Y0 Z0.730 ; Z switch offset

If on the second M558 command I remove the P8, when I do a G30 I get an error message of
"Error: in file macro line 47: G30: Z probe 1 not found"

So I do not understand the patch note of only having one with a P parameter, or am I doing something incorrect in my M558 commands ?

Cheers, thanks !
That was it

uploaded dwc3.11 on my duet 2, and now the DWC is a blank white page.
Tried 2 different browsers, nada.

I used the github page, download DWC Zip, it downlaoded as DuetWebControl-master.zip
Used DWC to upload, and now all white, when i connect via name or ip

Im setting up one of my printers with dual extrusion, using 2 separate hot ends.

So I have 2 hot end fans and 2 part cooling fans. Since i can't have 4 PMW type fans with the duetwifi, its 3 x PMW + 2 x Always-on...
What would be the recommended setup?

1. • put both part cooling fans onto one PMW and the 2 hotend fans on the other 2 PMW.
2. • put both hot end fans onto the "always on" fans and control the part cooling fans with 2 PMW fans
3. an option i have not thought of

As an update, I went with a Moons 1.8 stepper, 0.46 Nm.
Works well so far with very smooth looking surfaces so far.

@frank26080115 Very interesting re the changing of the shaft and having the ripples disappear. I really like the flexible shaft direct drive on a delta printer as it removes the Bowden and doesn't add the motor weight. Next time I get motivated to try it again i'll try your suggestion.

Im still quite a newbie in this realm and i guess the amount of variables are getting to me

Backstory is I have a zesty nimble, which worked amazing but had 2 issues I cannot solve

1. Ripples in the surface finish - Company is still working on a fix
2. blobs at the end of a layer creating terrible Z seam scars

Tried all the ideas such as coast and wipe, but they have their own issues such as only available in some slicers, cannot be used with firmware retraction, etc.

Pressure advance by the sounds of it should eliminate the blobs at end of layer, but any attempt to use PA with a nimble due to its required low jerk values caused my prints to slow to about 3x the time. Was painful to watch.
Although, with the nimble I was able to get a great calibration part from the above enclosed script.

With the nimble, the calibration part has easily discernible reversing thick areas, and one can find the "best" setting of 0.12, but pressure advance was unusable for me in combination with the nimble.

So I order a Bondtech BMG and use a capricorn bowden tube of about 650mm paired with an E3D 0.9 degree stepper.

Now i get the Esteps all setup at E808, run some retraction calibration parts, and i still get blobs due to pressure at the end of a layer.
Run the above scripts on a Pressure Advance test and..... The results do not make sense to me.

Before the extruded line ever gets to an optimal state, the extrusion is messed up. It gets to the point where nothing is coming out of the nozzle at all. I was at 5-100 print speed so ran again at 20-80 which is the speeds I actually print at (E3D volcano, 0.6mm X nozzle)
And again the part never gets to the optimal PA value without the PA settings making the filament retract so much it doesn't print.

What am i doing wrong? Any suggestions?

Duet Wifi, Smart Effector, newest firmware, Delta printer based smilar to DC42's large kossel

Config is as follows :
M350 X16 Y16 Z16 E16 I1 ; Configure microstepping with interpolation
M92 X200 Y200 Z200 E808; Set steps per mm original
M566 X1200 Y1200 Z1200 E2000 ; Set maximum instantaneous speed changes (mm/min)
M203 X18000 Y18000 Z18000 E3600 ; Set maximum speeds (mm/min)
M201 X1000 Y1000 Z1000 E3000 ; Set accelerations (mm/s^2)
M906 X1000 Y1000 Z1000 E900 I30 ; Set motor currents (mA) and motor idle factor in per cent

I have a delta printer, based off of DC42’s large Kossel build.
Duet Wi-Fi , smart effector, E3D volcano with .8mm nozzle.

I have been using a nimble extruded but am tired of endless calibration and never ending blobs and ripples. I have a titan extruded sitting in a box so I’m looking at going back to that and a Bowden tube.

With the nimble it was recommended to use a 1.8 degree motor due to the gearing. What is recommended for a titan and a volcano setting ? 1.8 or 0.9 ? My power supply is 24v if that matters in the decision.

Maybe a dumb question but...

If i use a PT100 on my duetwifi, do i still do the PID process ?
If so is there any special parameters in the M303 or M307 commands ?

I'm just jumping back into this 3d printer adventure, printer being down the last 6 months.

I have a zesty nimble, and volcano using 0.8 nozzle and am using PETG.

I have yet to find a good combo of settings to get my prints to where I want.
I have also just started playing with Pressure advance. Using the calibration print that is in another thread with the python script to adjust it, It tells me I need 0.17 pressure advance.

This then makes my prints extremely slow, so I have upped the jerk from the recommended 40 to 80 and 100.

I'm no longer sure the correct methodology for calibration with every new variable.
The above mentioned print is great for calibrating Pressure advance, but what is a good methodology/calibration for acceleration, and jerk ?

I have two delta printers, one printer with a titan and one with a Nimble. Both are great, although I prefer the nimble due to ability to use more plastic types (ninja flex) and reduced retraction distance with a direct drive.

I've also now encountered this but only since upgrading to the latest 1.20b8

Cool, if your brother get an iPhone X you can probably unlock it

@dc42:

That does look bad. My guess it that they are triggered by the combination of using pressure advance and a RDD extruder drive.
The other thing you can try is repeating the print with no pressure advance.

The same print with pressure advance off, no other changes.

=== Move ===
MaxReps: 12, StepErrors: 0, FreeDm: 240, MinFreeDm 120, MaxWait: 4200683977ms, Underruns: 0, 0

So it went from StepErrors: 15494, to StepErrors: 0 by turning pressure advance off.

I have recently switched hotends to an E3D volcano and i'm trying to run through some calibration prints.
When I do a M122 diagnostic, I have a high level of steperrors.
I was printing this calibration item https://www.thingiverse.com/thing:33902

=== Move ===
MaxReps: 12, StepErrors: 15494, FreeDm: 240, MinFreeDm 120, MaxWait: 15076805ms, Underruns: 344, 0

What can cause this? And what would be a good course of troubleshooting it?

It is a recent build, based on DC42's large delta. The motors are 0.9 for the XYZ and 1.8 for the extruder. The extruder is a zesty nimble direct drive mounted on a smart effector with a E3D volcano and 0.8mm nozzle. Print speed is 40mm/s with PLA at 220 degree nozzle. The flow seems good, but perhaps the extruder cannot keep up and I need to increase my extruder motor current. Would that account for the errors ? Is there a way to see what stepper is generating the errors?
