Using the Duet3 WiFi 6HC board, can I connect to my diode laser
(on cnc) directly with USB and control it using LIghtburn functions instead of DWC?
If so, is there anything I need to configure to do so?
I've tried to search here, and Lightburn, and YouTube but haven't found how.
I would like to thank all for this question - as I was just setting up and connecting my filament out sensors using a mini-micro switch (tyipical endstop switch).
I didn't read anywhere about just using 2 wires - and having all three just wasn't working.
for polbofree … if it makes any difference for you - I had to disconnect (not use) my voltage-in wire (the middle one on the DuetWifi endstop) .. and just used the two outside signal and ground.
... anyway I hope you get your's working ... but - again thank you for the question and Dc42's response!
Dc42 - will your new optical/laser sensor use all 3 wires?
Thank you very much .. that will help a lot .. hopefully someday we'll be able to use the DueX5 endstops as well.
This will give me enough as I've read the GCodes on the wiki several times to at least give some points to experiment with.
Hi All ..
I know you're working on the new filament monitor - which I'm really excited to see come out.
In the meantime I'd like to add my own micro-switch filament out sensor to allow me to pause the print when the filament is out.
I have been able to look up on the Wiki and here in the forum info on how to do that .. for 1 sensor.
However, I'm doing an IDEX set up and have a U Axis.
I'm currently using the enstop headers on the DuetWifi … X, Y, E0(U) (My Z 'endstop' is a BLTouch)
For the sensor I'll need two headers. I know I can use the E1 endstop, but can I use/re-map the Z enstop to do the same?
And/Or .. is there a way to use the DueX5 endstops for this purpose. - Somewhere in everything I've read, it sounded like I couldn't us the DueX5 enstops for this.
Any direction - Gcode, etc would really help.
I'm not sure if this thread should be here in this Filament area - or in Hardware and Wiring....
Thanks!
So … trying to wrap my head around this ...
I would set up the Tool2 as described in the above link.
(I'm assuming I can have that configuration for Tool2 in my config.h file and just leave it there all the time)??
In my slicer (which is S3D) .. I would add a profile/printer that has a 3rd Extruder (Tool2).
Then place a single model on my platform in a position that allows for my X offset
Slice it normally (as a single model) - which would show up only once in the slice preview
Send it to the printer and it will print the 2up duplicate.
Is there anything else I'm missing on the setup?
Thank you so much … that will be a big help!
David - thank you, this looks to be exactly what I needed.
I don't currently have any M584 commands in my config file - I guess I didn't need them because I was just using the 'normal' drivers for each motor and didn't need to 'remap' them.
Since I will need to use a Duet expansion board - this will accomplish what I need.
… oh - are there any examples of tool change code / parking / etc for IDEX set up? (being lazy here I guess)
Thanks
Hi - I've tried to search the forum as much as possilbe for my answer - but haven't found it yet.
I'm wanting to had two Y-Axis motors for my set up. Motor will be mounted on the front of the printer.
As I see it (in my set up) - to move the carriage/axis forward, the right motor must turn counter-clockwise, while the left motor will have to turn clockwise.
Can someone help me know how to map the motors, and set the different rotation for each to sync?
I am using a DuetWifi, and will be adding a Duet5 Expansion board.
Full set up:
2 Z motors Leadscrews for Dual Z-Axis
2 Y motors for Y-Axis
2 X motors (1 each for IDEX) Dual X-Axis
2 Extruder motors (1 for each hotend)
Thanks!
thank you for that clairification.
While doing a calibration test - I found that if I tried to push the filament anything over 5mm/s from the Duet Web Interface - it was like the filament just couldn't push through the nozzles.
The extruder wasn't really skipping - more like the it was pushing hard, but just would grind on the filament.
Once I turned it down to 5mm/s - it was just fine and I could calibrate. I don't know at what speed between 5mm/s & 10mm/s is the limit but I know 10mm/s didn't work.
I ended up with:
M92 E430:412
Unless there is something else I can do - I suppose my speed is really limited to how fast the nozzles will allow filament through.
This is on E3D Chimeras with Titan Extruders with ~50mm of bowden tube from the bottom of the extruder to the Chimeras. Both nozzles are .6
I do have the extruder steps/mm set lower in my config as:
M92 E400:400
However - that was based on a 'cold' calibration - just pushing 100mm of filament before I added the nozzles .. so that really could be off. I'll do another calibration actually pushing hot filament.
So .. apparently the steps of:
M92 X100 Y100 Z400 ; Set axis steps/mm
in my config is ok .. I've just seen so many others with different or fractional steps - so I didn't know if it should be fine tuned to something else.
Thanks all for your time.
Thank you - that helps with the extruder … I'm using the pancake because of weight - they are on the X axis - but I have some others I can try.
It's not really 'skipping' .. when I push it faster than 70mms - it just seems like not enough filament is getting pushed through. I do have .6 nozzles - but - if 'Tom' can push enough for Volcano nozzles - I figured I could on a .6
What about the X, Y, Z microstepping .. are those correct in my config?
Can I improve those?
So.. I'm a newbie to a lot of this jargon. I've tried to read through as much as I can on the forum and RepRapWiki, etc to figure out what I 'really' should have configured in my DuetWifi - but I'm just not sure. The threads have been great - I'm just not sure I understand it all.
So.. I have a CORE XY printer I've built (D-Bot) .. which seems to be working pretty good - but I'm really wanted to fine tune the accuracy/speed, etc.
Chimera w/2 Titan Extruders
I'm running Nema 17s for the XY and 2 Z motors (https://goo.gl/djfM2Q)
1.8 deg steps / 1.5A current
using 20 tooth pully on XY
driving direct on Z motors
Nema 17 pancake (2) for 2 - Titan Extruders (https://goo.gl/RmaKOs)
1.8 deg step / 1.0 A current
I can push the speed faster .. 60mm to 90mm, but it seems the extruders can't keep up - so, I don't know if that's the microstepping, current or just inherent with the motor/titan setup.
I don't have anything defined for setting microsetting (I don't think) - so I assume it defaults to 16X
I would like to get good accuracy + good speed (the best combination of both)
I'm currently running the 1.17.c Firmware
This is the current config for Machine Movement - any help to improve/fix would ge greatly appreciated!

where is this interface.js file - how do I find it .. that needs to be edited?
It turns out - and hence my OP question - that one of my Titan extruders was in fact skipping. I thought at first the motor wasn't strong enough .. or that there was a clog in the nozzle - or that .. well.. 1/2 a dozen other reasons I was checking.
As it was .. I just didn't have the current set correctly. It was set at 400mA (it probably came from a copy/paste doing the config) .. and it really should have been 850mA
Once I made that adjustment - so far, it's been working great.
Thanks for everyone's input and help.
I'm guessing that you have a long Bowden tube between the extruder drive and the hot end. Try enabling pressure advance.
What is :pressure advance" - and how do you enable it?
I just wanted to confirm I was figuring the current correctly for my extruder stepper motors.
Based on the wiki article: https://duet3d.com/wiki/Choosing_stepper_motors
I figure that my current should be ~ 850ma for this stepper motor: (short body Nema 17) https://goo.gl/Pu8xLX
Rated Current/phase 1.0A
1.0 * 85% = 850ma ??
Am I figuring this correctly?
And since I have 2 extruders/motors my config.g would be like:
M906 X800 Y800 Z800 E850:850 ; Set motor currents (mA)
That makes total sense now where S3D comes up with the .27 - I apologize for my ignorance.
It appears then, that I have some issues I need to re-calabrate for my nozzle and bed leveling to reset my z height in the config file.
Thanks.
I have gone through the process of setting the IR Zprobe and the nozzle leveling to 0 Z point using the paper method - and that all seems to be working fine.
However, when I go to print after slicing in S3D the nozzle never positions to the 0 Z point.
It defaults to Z .27 and when looking in the g-code of the sliced file I see this:
G90
M82
M106 S0
G28 X0 Y0 Z0 ; home all axes
G29 ; probe the bed
G1 Z30 F5000 ; lift nozzle
M109 S235 ; set the extruder temp and wait
G92 E0
G1 E-3.0000 F2400
G1 Z1.050 F1002
; layer 1, Z = 0.27
T0
; tool H0.300 W0.900
; skirt
G1 X72.644 Y79.826 F4800
G1 Z0.270 F1002
I don't see where the .27 is coming from in S3D .. if I set the z-offset in S3D to some negative number (e.g. -.09) then the line in the g-code will change accordingly:
G1 Z0.180 F1002
I guess I was assuming if I left the z-offset in S3D to '0' - then the g-code would set the code to something that would work closer to the 0 Z position.
If anyone with more experience with S3D can help me out here … do I just need to set the z-offset in S3D to -.27? .. which of course I can, I just didn't understand where that is comeing from in S3D.
