I've been trying to write a script to put in the start up code in Simplify3D to prime the nozzle. I want it to sweep downward to the bed while extruding (had a machine that did that), i tried working with Grok and it tries but doesnt quit get it. Heres the code grok wrote: ; Slicer start G-code with fully dynamic sweep
G28 ; home all axes (ends at G31 Z via IR probe)
M83 ; relative extrusion mode
G1 E5 F600 ; prime 5mm at probed height
G91 ; relative positioning
G1 Z10 F1200 ; lift 10mm above G31 Z
G1 X40 Y5 Z-10 E15 F600 ; sweep down 10mm (to probed Z), across 40mm, Y+5mm, extruding 15mm
G90 ; absolute positioning

Does anyone have such a script that works?

@droftarts Thanks for the advices. While waiting for a usb extension cable, i decided to check the sd card, and found all the files in the sys directory are gone. Fortunately i have an old sd card with working files on it. Inserted it into the duet and wholla, it works! I suppose the config is out dated but i will be able to update it over time. i dont know how the files were deleted, except i did delete gcode file and somehow the sys went too, i guess?

I'm on my 3rd Duet2 wifi, they have all had problems. The wifi suddenly stopped working on this one after a year or so. The wifi lights that normally flicker on at start up no longer come on at all. I've removed the memory card and reinserted it. How can i troubleshoot it? Thx in advance.

Does anyone know how to configure Orca slicer with Duet2 wifi machines? I've used mostly S3D for many years and tried others like Prusa, but now i have a Bambu x1c and it slices way better than S3D and i would like to use it on my old Duet printer. Ive tried many times but cant get it to work. I am able to connect to the duet2 ui but sending to the printer always fails in one way or another. Rlight now after sending print via wifi it uploads and heats the nozzle then always skips to 100% complete and turns off nozzle without printing anything. My machine is custom built reprap, no brand.

@Phaedrux Thank you. Never heard of buck converter, so thanks again.

@deckingman Thank you and the others, you have made my day, saved me a lot of stress and money.

@gtrider Thank you. You have also made my day.

@engikeneer Really? I thought when i bought the board i had a choice 12v or 24v. Wow, that changes everything. So would i just get a 24v power supply and everything would run?

@Phaedrux Well yes, except thats 7 or 8 motors plus a new board and a new extruder, I could use a new board i guess since none of the fan outputs work, its happened on all 3 duets i've bought. I dont know if that has been fixed but i sure dont want another one like that.

I'm finding the 40 w heater is just not enough and want to go to 60w but the heater suppliers only sell a 60w 24v heater (revo). So the 40w cant keep up and i get heater faults when using larger nozzles. I have the mini board attached (dont know what its called) so the power is not coming off the duet board (i think)

@ziggymanpopo I am using the pt100 daughter board, dont recall having to code anything. I am using the hemera revo, thermister/heater combo. And now the revo high flow, they dont make a 60w 12v version, just 24v, so im stuck with 12v 40w, so slower prints eg 40mm/s with 1.0 nozzle.

After doing the PID, after the fourth try, it started to perform correctly. So as of now all is well, no need to persue it further, and the supplier is sending me a replacement heater, so should be ok for a while, a long while i hope.

Thx for your help.

@ziggymanpopo were u able to find the code u mention re Hemera?

@deckingman well noted, and thx for the good advices

@deckingman great! thx so much, just checked and the M501 is the last line in my config.g, not sure if it was always there or not. I've done several small prints now without issue

@brian and then i ran M500 and checked the config.g override file and the info was there.

Does mean its good to go?

@brian OK i ran the PID and these are the results;

@ziggymanpopo In what docs? No instructions or guides of any kind came with the herera.

@deckingman No havent, didnt know there was one. Can u direct me to instructions? thanks

@jay_s_uk No

I just changed to the Hemrra extruder with revo nozzles and heater. And my Duet 2, keeps shutting down prints because of heater faults. Heres my heater code:
; Heaters
M308 S0 P"bedtemp" Y"thermistor" T100000 B4138 ; configure sensor 0 as thermistor on pin bedtemp
M950 H0 C"bedheat" T0 ; create bed heater output on bedheat and map it to sensor 0
M307 H0 B1 S1.00 ; enable bang-bang mode for the bed heater and set PWM limit
M140 H0 ; map heated bed to heater 0
M143 H0 S300 ; set temperature limit for heater 0 to 120C
M308 S1 P"e0temp" Y"thermistor" T100000 B4725 ; configure sensor 1 as thermistor on pin e0temp
M950 H1 C"e0heat" T1 ; create nozzle heater output on e0heat and map it to sensor 1

Could there be something in the code causing errors or that could be changed to allow more flexibly paramenters? Or is it more likely to be a defective heater, only be using about a week. Had about 10 heater faults, the last one said set temp 200 and heater was at 226, most unusual.
