@infiniteloop @droftarts It was the fan miniblade fuse! Should've checked this sooner but haven't blown many fuses yet, lesson learned. I had even swapped my Duet 2 wifi with another at a point so I thought no way both have a blown fuse....sure enough they both did. I think it was long before I was setting up this machine as the electromagnet has less than 1A draw on 12V, but I'll be double checking

Trying to use the fan ports on a Duet 2 wifi to control a 12V electromagnet. I have the fan jumper on the VIN selection and the board is powered at 12V. However, my always-on fans (just as a check) never turn on and I can't turn on the fan0 with M42 either. I checked both sets of pins with a multimeter and didn't get much of a reading, but unsure if you can given the PWM signal (though I thought I had before). M98 on my config yields no issues either. Any help is appreciated

@droftarts this was what I needed! I had been using the table above that, that says PCB Pinout, but I'm now realizing it's for the BL Touch's pins not the boards. Thanks!

@mikeabuilder it did live in a cable chain for a while but since troubleshooting and the rewire its been removed and still seems to have the issue

@Phaedrux yes the self test upon startup is working fine, which is the first time I've seen that working but holding a triggered state in DWC. It is wired like so to my MB6HC:

By servo commands do you mean just sending M42 or M280 commands to try and get it to go manually? If so I haven't tried those yet and will give that a go next

@zBeeble Unfortunately I tried a full rewire and different set of pins before posting this

My BL Touch deploys correctly upon turning on my machine but doesn't respond to M401 or M402. The Z-Probe signal in my DWC seems to always show it as triggered so when I try to test dynamically it ofc triggers immediately. I seem to have it wired correctly so I believe something in my config.g is wrong. Just looking for a second set of eyes to see if anything sticks out in my config.g or where else to look. Thanks in advance!

@dc42 appreciate the clarification. I assume polling is the only way with ethernet boards then?

@oliof I had never heard of this but just did some reading. How cool! Thanks for your quick response

I read a few posts from 2017 and 2018 talking push notifications and webhooks. However, it seems like RepRap Notify was the most cohesive project to tackle that problem and is no longer maintained with newer versions of Reprap. I'm wondering if any other developments have been made on this topic? Is polling rr_model the best way to get notifications when jobs are complete or other events happen?

@dc42 The first half of that makes sense. I'll play around with some other potentiometers, revert back to P1, and take the ! character out.

However, I'm uncertain about the series resistor you mention. Are you recommending adding another resistor in series with my pot in order to find the resistance that gets it triggering? or how do you mean?

@chrishamm Thank you! I didn't realize you could literally use an asterisk. I thought it was a placeholder

@chrishamm I'm sorry I'm not much of a software engineer so pardon my ignorance, I'll need some additional clarification. Would the C"site" be the site requesting the HTTP post like the backend of my app, like a localhost:3000? Or whats a correct "site" if not?

@Phaedrux Yes I'm using these DF9-40 FSR's all wired in parallel with no board. Switching to mode 8 didn't have any effect

Hello,

I'm continuing to work on a web app that can upload .gcode files to my machine. However, I've been unable to connect with my machine through HTTP requests. What is the correct formatting for an endpoint for this API? I currently have it like so:

http://xxx.xxx.x.xx/api/files/gcodes but didn't have too much confidence in that.

Additionally, I noticed M586 has a C variable for setting the site of cross-origin HTTP requests. Can I use this to set it to that exact same endpoint or how is the C variable effectively used in this case?

@Phaedrux That helped me clean up a few things but now it's just not triggering at all. Here are my new files

Hello,

I'm trying to use FSRs as a z probe and have them mounted on my bed. However, I get the error "G28 Z Error: Probe already triggered at start of probing move" immediately upon trying to home my Z. I'm using a 10k potentiometer, but tuning the resistance on it seems to have no effect. Here is how I have it wired and my config. g.

Hello, while reading through the test and calibrate a Z probe page I noticed that you cannot statically test FSRs as the pulse may be too short to notice on DWC.

I want to setup a test bench of just my bed and the FSRs to see if the sensors I choose work and if the arrangement is effective. Will the pulse be observable from the DWC if I continue to keep a force down on my bed such that it's longer than the nozzle briefing touching? or will it still only pulse once quickly right when the force is detected? Is there a better way to test the effectiveness of my FSR setup without a whole extruder?

Hello, I'm working on a web application to do some batch slicing, then automatically send the files to the machine to start printing. I noticed M32 is used to select and initiate the file from the SD card at .../gcodes.

I'm here to ask the best way to upload a .gcode file to the /gcode folder on the SD card using Java/HTML. Is there a way to use SSH/SFTP for File Transfer or HTTP POST? I'm only a novice when it comes to development so a little unsure how to approach this one.
