Hi! I'm new here and I would like share with you my 3rd, but 1st, designed and builded from beginning to the end by my 3d printer.
Shaping from marlin to reprap was nightmare for me (I was writing some codes for Arduino so C was closer then gcode) but now I need to say - it's the best ecosystem ever made!!!

Some about printer - cartesian style, 2 Y motors, temporary 2 Z Motors. When was designing it main point was to have solid mounted bed (with springs of course). So I have 2x 0,72Nm Z Motors (ordered 2 more for independent screw leveling), 2x 0,45Nm Y motor and 1x 0,45Nm X motor. Extruder is direct drive Mellow wind with pancake motor and volcano hotend.

I'm adding also my config.g file and would like to ask you - do you have any advice what to change?

How find maximum accelerations and jerk values for X Y and E Motors? Do you have any way to do that?

Did homing separate - working great. THX

Hi!
Is there any paypal/patreon etc. Where people could send cash to help developing duet ecosystem?

Funding Marlin is easy - there is something about on the main page but it's hard to find any info for Duet and reprap firmware

@button
Ok, I enabled support for paneuldue in config.g and comunication via bossa works over paneldue uart

I'm using OrcaSlicer for 3 months and pirint looks briliant. Same settings, copied from SuperSlicer and quality is flawless

@droftarts
I'm using usb to uart converter connected with jumper wires to paneldue connector on duet2wifi.

Ps. Yes, sorry, i meant YAT

Hi guys.
Finaly have some time to fix some things in my Voron v0.1.
I have 12864 display connected to Duet3Mini.
I'm using Ultimate Duet Menu System and wanted to change some behaviors but discovered that is duet limitation, not menu system:

; Bed Temp
image R14 C25 L"imgs/bed.img"
alter R14 C40 N180 W20 H2
text T" / "
value N80 W20
text T"°C"

; Hotend Temp
image R26 C25 L"imgs/temp.img"
alter C40 N100 W20 H2
text T" / "
value N0 W20
text T"°C"

When setting up bed heater active temp, bed getting active (from standby) When setting temp to 0 in web interface is showing -272 (and somehow i can set temp to -xxx value).

When setting nozzle/tool active temperature tool not getting active (i must add extra button to make this took active). When i set temp to 0, took getting OFF. Why?

Is there an option to:

• use conditional Gcode in menu files?
• adding extra behaviors to "alter" component? (If temp is lower then eg 20 put tool to standby, not off)

@Phaedrux yes, was also and option for us, but when i told to my friend "remember to enable paneldue in config" i discovered that this was the thing we missed to comunnicate via usb to uart converter

Hi.
Friend of mine destroyed USB socket on his Duet WiFi board. We must connect the printer to another network - how to send proper comands?
We were trying to do that via PanelDue port, but board is not responding. Also adding M552 etc comand at the end of config.g doing nothing. Do You have any ideas how to do that?

@deckingman
I was thinking about loosing sync between both motors and eg. building pressure in bowden tube because one motor will be going faster (steps set correctly)

@wwak84
But problem is that my main question was about 2 extruders pushins same filament to 1 nozzle

Oh, and i cant tell machine where it should start prinitng because eg tool 0 was printing object 1, and tool 1 starting printing from object 3.

@wwak84
From the begining:
You're printing with tool0, then coming T1 command from slicer - and tfree0 macro is called and tpost1. In macro tfree0 you gave eg G1 Z2 line. In tpost1 you cant gave G1 Z-2 because you'll move head down before it reach printing position in XY. Machine to move T1 head to the printing coordinates in X and Y and then lower gantry in Z. Not before. After XY movement. SuperSlicer not sending Z when you're not using wipe tower (it won't use it)

@wwak84 duet with duex has 10 steppers, all in use right now.
All of tutorials from duet wiki I've done. Its slicer, not duet problem - how RRF could know when lower Z after 1st xy move after toolchange?

Simulationusly meaning spool->feeding extruder->bowden tube->direct extruder
