OK, thanks.

Hi there,

Got a nice Hemera and tried to get the retract settings for TPU right.

Made some test, but no matter what, it´s stringing and blobbing.

i created a retract test part, sliced it with prusaslicer and added after 10mm commands like M207 S or F

I didn´t noticed any difference, so i searched the problem and found it.

In prusaslicer, retract is set to 40mm/s and 0.5mm retract.

When i do a single "M207" before starting a print, i get the following:

M207
Retraction/un-retraction settings: length 2.00/2.00mm, speed 1000/1000mm/min, Z hop 0.00mm

Then i start the print and typing again M207, the console answers this:

M207
Retraction/un-retraction settings: length 2.00/2.00mm, speed 1000/1000mm/min, Z hop 0.00mm

Where gets the duet2 these settings for retract?!?

Any error messages?

My Problem was a missing "t0" in the Start Code

i got it.
I just added "M109 S[first_layer_temperature]" to the start code.

I couldn't imagine doing it like that.

i think i got the problem.

M190 S120 ; set bed temperature and wait for it to be reached
M104 S255 ; set temperature
;TYPE:Custom
T0 ; Sets Tool0 as default
M106 P0 S0 ; Stop Part Cooling Fan
G28 ; home all axes
G91 ; relative mode
G1 E52 F300 ; Fill Nozzle
G90 ; absolute Mode
M109 S255 ; set temperature and wait for it to be reached
G21 ; set units to millimeters

with that gcode, the error message is gone, but there is an advice. "tried to extrude, but the extruder is not at temperature"

it wants to prime the nozzle BEFORE M109 S255.
This command appears after the start code and seems to be written by prusaslicer. Now, i don´t know how to change the order.

@Torro said in Problems with prusaslicer 2.3:

Error: Attempting to extrude with no tool selected

No, i didn´t. but it´s a good idea

I added "T0 ; Sets Tool0 as default" to the start code in the slicer. the last lines in my config.g are here:
; Tools
M563 P0 D0 H1 ; Define tool 0
G10 P0 X0 Y0 Z0 ; Set tool 0 axis offsets
G10 P0 R0 S0 ; Set initial tool 0 active and standby temperatures to 0C

I still get this error message. With gcodes created by S3D, there are no error messages, so i think, that config.g should be ok.

Thanks!!

OK, thanks. i try it.

Hi there,

I´m playing with the prusslicer 2.3

when i start a gcode, the heaters heat up and the printer homes. than there is this error:

"Error: Attempting to extrude with no tool selected."

The printer starts printing anyway.

I changed the "gcode flavour" from reprapfirmware to reprap/sprinter. with reprapfirmware, the hotend didn´t heat up.

Here are the first lines of the gcode:

M107
M190 S120 ; set bed temperature and wait for it to be reached
M104 S255 ; set temperature
;TYPE:Custom
M106 P0 S0 ; Stop Part Cooling Fan
G28 ; home all axes
G91 ; relative mode
G1 E52 F300 ; Fill Nozzle
G90 ; absolute Mode
M109 S255 ; set temperature and wait for it to be reached
G21 ; set units to millimeters
G90 ; use absolute coordinates
M82 ; use absolute distances for extrusion
G92 E0

Has anyone an idea, how i get rid of this error message?

Thanks!

I did that with a ssr relay. Connected to the ps_on Pins from duet and a push Button.

Ps_on pin from duet is Connected to the ssr minus.

In the end Script from the slicer, i added
M81 S1.

I tried bed leveling with different probes, ir probe and bltouch.

My Problem was different trigger heights at different locations on the bed with both probes.

Check that. Trigger height should be the same, no matter where you probe on the bed.

I think the printhead is somehow twisting.

Good luck!

i rewired the printhead. the printer was on, because i needed the light.
so i cut the complete cable with 24V/5V. fortunately, i just needed a new fuse for the fans...

i don´t know what i was thinking...

I did exact this using stall detection for Z max.
It's a bit tricky to get the detection working, but it works for me.

The key was to Reduce motor current and increase the Speed.

@dc42 said in Duet Wifi upload speed question:

M122 P104 S200

SD write speed for 200.0Mbyte file was 1.77MBytes/sec

nearly 2 minutes

Hi there,

i have a small issue and don´t know what to try next.

the problem is, the bigger the file, the slower the upload.

gcode about 200MB, upload speed starts at 40KiB/s and ends at about 400KiB/s
a small file with 2-3MB is done in a heart beat. and DWC shows something between 960KiB/s and 1.3MB/s

M122 shows WiFi signal strength -42dBm, reconnections 0, sleep mode modem

i´m using a USB3.0 external HDD, connected to the router.
when i upload from the computer directly, the upload speed for bigger files is about 500KiB/s.

M122 P104: SD write speed for 10.0Mbyte file was 1.89MBytes/sec

is the microSD the bottleneck? it´s a sandisk class 10.

Thanks!

got it working. getting connected guide helped.

...get the duet wifi connected again?

I took the sd card, changed the SSID and password in config.g and put it back to the duet. unfortunately, it won´t connect.

what am i missing?

thanks!

I tried it with driver 2 and 4. Didn't work.
There is a guide in dozuki, he uses driver 2 and 3. I changed it and it worked immediately. The extruder is connected to drive 4.
Only issue is, that you have to home Z first.

It's not transparent and not shiny.
the probe measures different trigger heights at different positions.

no, the probe seems to have problems with my bed surface.
i gave up the leveling.

Try changing M98 Phomez.g to G28 Z

Same behaviour. I just put the m98 phomez. G in the first line of homeall.g

Now it works as expected
