    • RE: Fried a driver circuit, now all drivers aren’t working?

      @dc42 I used a hot air station we have at work to remove the chip and the board works great now, thanks for all your help!

    • RE: Heightmap, fill in missing data and interpolation

      @fcwilt thanks, the issue come from the position of the probe relative to the nozzle (about -35X 25Y) and the travel limits of the gantry. The probe can’t physically get to those regions.

    • RE: Overloading the Duet 3 Mini 5+ with commands, causing stuttering

      Thanks everyone for your help, it looks like a new SD card has fixed the problem, which is great!

    • RE: Overloading the Duet 3 Mini 5+ with commands, causing stuttering

      @droftarts Interesting, so the SD card is the original that came with the board and the interface speed looks as expected: 22.5 MB/s

      But the read write test is very slow:
      SD write speed for 10.0MByte file was 0.43MBytes/sec
      Testing SD card read speed...

      Doesn't seem to ever finish the read test.

      Not much free space either:
      SD card in slot 0: capacity 7.95GB, partition size 0.26GB, free space 0.06GB, speed 22.50MBytes/sec, cluster size 512 bytes

      I'm not sure where its all gone, I regularly delete all the jobs.

      Could be a nice fix as I have another 32 GB SD card, once I format it as FAT 32 do I just copy all the files over? Can I reformat it using Mac OS?

    • RE: Overloading the Duet 3 Mini 5+ with commands, causing stuttering

      @Phaedrux Yes always on curves, and only with many parts on the bed and later in the print, like there's a cashe of memory that's getting filled.

      Its difficult to replicate as it requires the need to print quite a few curved parts (ovals or cylinders are the main culprits)...

      I can try with the deamon off, or is there a way to decrease the frequency which it runs?

    • RE: Overloading the Duet 3 Mini 5+ with commands, causing stuttering

      @droftarts Hi, yeah so the printer is a Zortrax M200 I've converted, I added a Duet 3 Mini 5+. I think its got Nema 16s and mechanically runs very smoothly. I took the diagnostics this morning after printing some parts that have a few stutter artefacts overnight:

    • RE: Overloading the Duet 3 Mini 5+ with commands, causing stuttering

      @cosmowave Yes so changing the resolution from 0.012 to 0.05, making it coarser.

      Interesting, I hadn't considered the daemon file. There isn't too much in there, just some code to control the LEDs based on printer status. Do you think this could cause a problem?

    • Overloading the Duet 3 Mini 5+ with commands, causing stuttering

      I've had a long standing issue where if I fill the bed with multiple round parts the printer seems to struggle to keep up and stutters causing blobs on the print surface. I don't have the problem if I print one single part, but multiple of that same part causes the issue.

      The other thing I notice it it gets worse later in the print, the first 30 mm is usually ok, then pauses start to happen over the next 40 mm getting worst near the end.

      My question is; am I really reaching the limits of the board's processor? I thought it was quite powerful.

      I can mitigate it by decreasing the slicer resolution (0.05 from 0.012), and arc fitting post processing also helps, but then I start to notice the curves becoming faceted and am still limited on how many copies I can print at once.

      Is there a solution such as using a SBC to process the commands, or is there anything else I can try?

      Some extra info: printing from the SD card, micro stepping 16x with interpolation, debug mode turned off for everything, jerk is relatively high at 600 mm/min, slicer is OrcaSlicer but happened previously on PS and SS

    • RE: Fried a driver circuit, now all drivers aren’t working?

      @dc42 that’s a good option, thanks! Do you think it’s possible to remove the driver chip with just a soldering iron (I have chip quick flux and some low melt solder)? I think the big ground pad could be a challenge.

      And would it be advisable to remove any of the other components in that damaged area or could that potentially cause more problems?

    • RE: Fried a driver circuit, now all drivers aren’t working?

      @oliof thanks for your help, yeah that’s what I was afraid of. No errors on startup, just seems like there’s no power to any of the driver circuits, as I can move the print head freely which I usually can’t when the printer is powered up.

      Here’s a photo of the back of the board showing some more damage:

    • Fried a driver circuit, now all drivers aren’t working?

      This is a Duet 3 Mini 5+. I was trouble shooting getting some LEDs to work on the tool head when a screwdriver bit made contact with the board on the Driver 1 circuit. Looks pretty fried but I was hoping I could use the spare driver as a replacement, however none seem to be communicating anymore.

      I've updated the config to represent the new mapping but any attempt to home the axis results in the an error with no movement. Is there a fuse perhaps that could have gone too? I can't see any other damage to the board other than the driver circuits the rest of the board seems to be working fine.
