I figured it out. I was poking around and saw that somebody else had an issue with the electrolytic capacitor and how it had lifted off the board. I re-soldered the capacitor down onto the board and thought I fixed it. It seemed to work, but once the board heated up from the residual heat I was still having issues.

I decided to look at the IR LED's through my phone camera, and only one was lighting up. As I pressed on the unlit LED, it lit up. I re-soldered the unlit LED, and now they both light up, and the LED doesn't lift off the broken solder joint as the board heats up.

If anybody else out there has issues with their boards and wants to check that the LED is working, look through your phone camera in the dark. It should show up as a pink/purple light on the screen.

I figured it out. It's crashing the head on the X-axis due to the probe point for the leadscrew being slightly off. I just need to adjust that.

@Phaedrux Added M558 with just the H parameter to my G29 macro and now it works perfectly. Thank you.

@Exerqtor I'm still waiting on more tests. My money is on the stealthchop issue. Apparently around 300rpm is where the problem arises. I'll do some quick math to see if that is around the 8mm/s where he was experiencing drop off.

@wilriker Would help if we knew exactly what was going on.

Also, if all is he looking to do is change power at the heater block he can change the PWM duty cycle and get the same results. If he's looking to increase power draw on a FET or something then he would need some power resistors.

@mrehorstdmd @zapta @mendenmh @mwolter @arhi I just replaced the Igus bushings with the LM16UU I ordered. No more issues. Now I have no idea what to do with all these Igus bushings I have.

@DIY-O-Sphere Okay, this is what ended up working.

The naming conventions for pins and thermistor inputs, as well as having the number offset for them seems like an oversight.

Hi all,

I've been looking at purchasing some shielded cable for certain steppers and components on my machine, but it seems that a lot of the stuff I have come across is garbage. Either CCA wire, or super stiff jackets.

I was digging around on mcmaster and I came across these options:

https://www.mcmaster.com/wire/number-of-wires~4/wire-gauge~20/wire-gauge~22/wire-gauge~24/flexibility~continuous-flex/

I'm specifically looking at these two, in 24 and 20 gauge.
https://www.mcmaster.com/8097T26/
https://www.mcmaster.com/8097T28/

Has anybody tried these? They are the cheapest on there, but look like they are solid wire with actual copper conductors.

@tekkydave Yep, mine is fake as shit. Looks like I need to get some better ones.

Yeah, definitely my Z-axis. I ran some prints and changed my pause and resume to not lift Z and the indentation is gone. Looks like I need to get some pillow block bearings for the leadscrews and new couplers.

@dc42 Yes, I am doing that now. However, I want the prompt to contain options that are dynamically created based on the content of "0:/filaments". I don't want to update the prompt every time I add a filament, or modify the name of a filament. Just like how DWC creates the prompt when pressing the 'Load Filament' button.

@chrishamm So I'm guessing there is no way I can implement a M291 prompt that pulls variables based on filepaths inside a folder?

Hey all,

I'm trying to figure out an issue I am having with filament changes. I'm not sure if this is a new issue, or if I just never noticed this before.

The way I have my duet configured is to use filaments stored on the machine.

I have a load.g, unload.g, and config.g for each filament.

Now, the problems arise when trying to load/unload filament from DWC.

First, if I select the filament from DWC and click 'unload', it heats the bed and waits for the bed to reach temperature first. Is this intended? This is even before it executes M702. This seems counterintuitive. Is this being influenced by tool change macros? When I run T0, it puts the bed into standby mode. However, my toolchange macros don't call for that to happen.

Also, when loading filament, it does not load the selected filament parameters before loading.

For example, if I have PLA loaded, with an active temp of 230, it will unload the PLA, keep the active temp of 230, then when it goes to load PETG it will keep the active temp of 230, even when running M703. I am assuming that this is because the PETG is not 'loaded' yet according to the system. Only AFTER all the macros are done, does running M703 update the temps.

Can anybody explain the logic here and help me figure out a way to get this to work, without needing to manually set temps in a load macro?

Here is load.g

M98 P"0:/macros/Filament/universal_load.g"

and here is the 'universal_load.g' macro

@droftarts If I trigger it using a filament error event, then it's just going to go into the 'filament-error.g' macro, and I end up in the same boat of not being able to get the dialog to pop up on screen with a physical input. It seems like the only way to trigger this dialog is with the button on DWC.

@chrishamm I know I can do it with M291, but that seems pretty clunky, unless there is a way I can extract the filaments by filepath in a subdirectory. I'm not sure of a way to do this.

Hello all,

I am setting up triggers so that I can load/unload filament with physical buttons/filament sensors on my machine. I would like to have it so one of these triggers activates the 'Load Filament' prompt. I have not been able to find anywhere in the documentation if this is possible. Is it only something within DWC?

Picture of the prompt I am talking about:

Can anybody help me with this? I know I could create a message with M291, and then select the filaments from there, but that seems to be a very roundabout way of doing it, and I need to make sure that the filaments in the dialog stay synced with the filaments in my filaments directory.

Thank you

Hi all,

I'm setting up triggers on my duet machine. I have an issue where a trigger may be tripped multiple times, like when inserting filament. This causes messages to be stacked, which is a pain. I am assuming that the way to fix this is to temporarily disable the trigger with the R-1 parameter in M581. The documentation says that "R-1 temporarily disables the trigger". What determines when the trigger is re-enabled? Do I have to recreate the trigger with M581?

Thank you

@droftarts So I got it all set up with triggers and it's working wonderfully. However, I would like to change the way it handles filament loading. Currently, when I put filament into the sensor, it runs my filament load macro. Is there a way I can get it to prompt me which type of filament is loaded, like on the web ui when I select the filament load? I'm not sure how to make that happen.

@droftarts Fantastic. That's exactly what I was thinking of, but I'm not familiar with triggers. I have the pulse sensor already hooked up, and I'm going to tune it now. I will look into the triggers/events afterwards. Thank you.

Hey all,

I just picked up some BTT Smart Filament Sensors V2.0. These sensors have a microswitch for filament detection, and a pulse generating sensor. I want to connect this to a Toolboard 1LC. I'm assuming I can use IO 0, and connect the pulse generating sensor to one of the pins, and then microswitch to the other pin. My question is, how do I setup the firmware to utilize both sensors? I would like to have it so the filament detection switch will run the filament load macro. Has anybody done this before? Can somebody point me in the right direction?

Thank you

Hi all,

I'm still working on the design of my toolchanger. One of my big issues has been finding a good extruder for the system. I was planning on going with the smart orbiter V3.0, but now I am having second thoughts. My initial thought was to go with the hemera xs, but the price point of the hemera xs and revo nozzles is too high, considering I will need to be making multiple toolheads. I was also considering the biqu toolhead, but I'm not sure on quality.

The main issue is that these must print flexibles. This is why I have been looking at hotend/extruder integrated combos pretty much exclusively.

Can anybody give me any input here? Currently I print with 2 hemeras, and they handle flexibles wonderfully.
