    • RE: DotStar on Duet Wifi 2

      @dc42 Thanks for the reply - Dotstars have a pleasing non-flickering warm glow that is easy on my eyes 😅. I have wired my printer with these for the last 2 years & they're awesome.

      Looks like SUPPORT_BITBANG_NEOPIXEL is the only path for DUET_NG which I'm guessing aliases duet wifi based on other usages. The rest are SUPPORT_DMA_* (exception being PCCB_10 which I'm not sure I know what it is). I guess the Wifi only supports bitbang? These preprocessor definitions are dense & I'm not quite sure yet what needs to happen to add neopixel bitbang for DUET_NG!

    • DotStar on Duet Wifi 2
      FIRMWARE_NAME: RepRapFirmware for Duet 2 WiFi/Ethernet FIRMWARE_VERSION: 3.4.0 ELECTRONICS: Duet WiFi 1.02 or later + DueX2 FIRMWARE_DATE: 2022-03-15 18:58:33
      

      I'm trying to connect a DotStar strip to a Duet2 as documented here for neopixels: https://docs.duet3d.com/en/User_manual/Connecting_hardware/IO_Neopixel_DotStar

      When sending M150 X0 P255 S20 I receive Error: M150: Unsupported LED strip type.

      I have an external 5v PSU and have been historically driving these LEDs via a CircuitPython m4 but I'm trying to simplify the wiring and maintenance burden of my printer. Is there any way we can get DotStar allowed on Duet2?

    • RE: Duet 2 Wifi: RRF3 + Raspberri Pi

      Ah I was trying to access DWC on the pi from my pc (or phone or laptop). I guess I could set up a reverse proxy to localhost to trick DWC into thinking the request came in locally and offer up a connect dialog..

    • RE: Duet 2 Wifi: RRF3 + Raspberri Pi

      How do I set the connection string for my printer when running DWC remotely?

      30d534e9-ef2f-4224-9a75-bbd8620f6511-image.png

      It spins connecting on my raspberry pi, trying to GET /rr_connect?password=reprap&time=2020-5-30T22%3A11%3A30 which results in 404 because how should it know where my printer is! I'm reading the code for dwc but I haven't found any printer connection query parameters or anything like I'd naively expect to see (or a machine connection selection box on dwc in the Machine Specific submenu)

    • RE: Duet 2 Wifi: RRF3 + Raspberri Pi

      Removing the WiFi module looks doable. I'm using multiple Z probes with 3.1.1 though, which I think is not as well supported on 3.02 (K parameter on homing probe command).

      Running DWC on the pi might be enough for now, and when I finally burn up my Duet I'll reach for a 3 and direct-wire to an SBC. Thanks!

    • Duet 2 Wifi: RRF3 + Raspberri Pi

      I have a Duet 2 Wifi + Duex and would like to use a Raspberry Pi to host DWC and other external printer functions. Is there a pin breakout of what to connect where between a 2 and a Pi, and what to do to safely remove the web code from the Duet?

    • RE: Bed-heated chamber PID temperature control

      @TLAS Thanks for the ideas! I'm not sure this will do what I'm after - for now I will just use 20% pwm while printing and hope temperatures stay relatively steady then amp up to 100% for a few minutes after printing to evacuate fumes through the charcoal. Might be a neat new gcode, I'll keep it in mind in case I get the urge to contribute to rrf.

    • Bed-heated chamber PID temperature control

      I have an enclosed chamber with a large bed. There is a filtered vent on the back and I'd like to modulate the speed of the extraction fan to hold a target temperature (e.g., 50c) in the chamber. On a previous printer I made a microcontroller, display and rotary encoder to set it by hand. With a Duet 2 Wifi I'd expect to be able to set this up via gcode.
      Reading the GCode page I don't see an affordance for it, but I'm new to RRF. How do people configure this kind of behavior?

    • RE: Wifi 2 SPI Timeout

      @dc42 said in Wifi 2 SPI Timeout:

      Leaving your network password on the SD card is a security risk. Don't do it.

      In fact this is the only reason it occurred to me to remove from config.g. If that data were not somewhat sensitive I would have left it and never found the solution.

      A oneshot.g or something could work though - read once and deleted by the firmware. Or just decline to provide the m587 at all and let users find the command. 🤷 I'm sure you're more than capable of doing the right thing for rrf on this minor issue. Thanks for looking into it!

    • RE: Wifi 2 SPI Timeout

      The firmware configuration tool spat out m587 into config.g yes. Through trial and much error I took it out and ran that via serial. The m587 seems to have been somehow poisoning the startup of the wifi chip.
