      @Phaedrux I have sent off an email, yes.

    • RE: Maestro issues (Firmware not updating and no ethernet)

      @dc42 Is there any way that we can try and debug the SPI connection between the MCU and the PHY through firmware?

    • RE: Maestro issues (Firmware not updating and no ethernet)

      I just received a response from my reseller saying that Duet discontinued the Maestro? Is this true? I haven't been able to find it in stock anywhere in Canada.

      Do you happen to know what the SPI frequency is?

    • RE: Maestro issues (Firmware not updating and no ethernet)

      I assume I would need a logic analyzer or oscilloscope with decoding functionality in order to do that?

      Are the pins exposed on some easily accessible test point? I don't see any traditional SPI pins on the back.

      Would it be possible for back-emf to destroy one of the stepper drivers is such a way that it would be messing up the rest of the SPI bus? I had my cantilevered bed fall a short distance before I noticed the board went bad.

    • RE: Maestro issues (Firmware not updating and no ethernet)

      I see. I'm kind of bummed out here to be honest, as this is the second piece of Duet hardware that has failed on me. The first being the IR sensor, which had a bad solder joint on the IR receiver, and now this. This certainly isn't something I would have expected from a premium product.

    • RE: Maestro issues (Firmware not updating and no ethernet)

      I purchased it from spool3d.ca on October 15th, 2019. It's taken quite a while to get everything set up - it has only done one print so far.

    • RE: Duet wifi Not Starting Print (Help)

      Please post the output of M122 (not M112). That will give us some information regarding the power supply faults.

      Do you happen to know the rated power consumption of the hot-end and heated bed?

    • RE: Did my board jist fry?!!! All lights work...but no movement?

      Yep, so my thought was that if the board was placed on an ESD bag while it was powered, the slight conductivity could have shorted some near-by pins on the back of the board.

      Here you go: https://www.dropbox.com/sh/d23sm2xxk35xh3v/AABKB4PaqMS7xzck2IXK-XPKa?dl=0

      (The little black circle on the bottom left of the Wiznet chip seemed to be a little bit of finger oil, which came off with some isopropyl. IMG_5878.jpg and IMG_5880.jpg were taken after cleaning)

      I don't see any obvious evidence of a damaged component.
