    • RE: 3 Bed Scanner Questions

      I use an MRW magbed with Buildtak flexplates, and the szp definitely shows the magnet positions quite prominently. I did see dc42 posts showing the magnets test on his scan with an MRW bed. I can reduce the the effect by scanning further from the bed but its still an issue. I did expect this so I'm not surprised.

      I do know that a lot of spring steel sheets can vary in their magnetic qualities, that some of the previous non branded spring steel sheets that I've used don't hold a candle to the Buildtak ones.... they stick really well. I wonder if lesser plates (magnetically/ferrous wise) would be better. I need to dig out some of my old ones to try.

      I also thought about stacking 2 Buildtak on the bed to see what, if any difference that makes. Need to try that too.

      I also need to try the manual mesh position file to skip around the magnets (assuming that works with the szp)

      Where can I get the scanning probe in the UK at the moment? Looked on E3D & Ooznest can't see it x

    • RE: Toolboard with built in accelometer +SBC - failed promise

      No promises have been broken, v3.4 has not been released yet. The release of all beta software is taken as read that its not the released version and is a work in progress. I think your expectations and understanding is flawed.

      @DIY-O-Sphere I'm ahead of you, it was always running off an external psu, but thanks 🙂

    • RE: Servoless RC undercarriage retracts connecting to Duet 3

      Just as a follow up to this, it is now working.

      This being my first foray into servos through the Duet, I hadn't realised that values with M280 beyond 544 were pulse widths.

      simply ran a loop sending increasing pulse widths every second from 544, broke in down into chunks, so did 300 at a time, until something happened, then narrowed it down from there...

      To extend the leg, the window was 666 to 1200, so 900 works well.

      To retract the leg, the window was 1740 to 2300, so 2000 works well.

      Oh yes before I forget, I'm running this off OUT9, which I understand has 5v pwm, not sure if it works off the other ports as I haven't tried it.

      Happy happy! x

      Thanks @DIY-O-Sphere that does look better, as soon as I get it working I'll order one of those. I don't have a design yet, but I'm going to bolt it to something similar to Gregs Adjustable Cleaning brush. Unfortuately I don't have the space to run Gregs as it is and will need a swing arm. Currently I have a stepper bolted to a mount, which bolts to a piece of extrusion which has a short piece of rail, and a leadscrew on the stepper. Just need to design and print the carriage, which will depend on whether I actually use the RC Retract thingie x

      Thanks @Phaedrux its supposed to accept a servo signal. I can get a normal servo working but when I swap it out with the Retract it doesn't do anything. Its designed to fit onto an RC channel with a 2 position switch, and I expected beyond particular values for it to trigger.... will have to play some more! x

    • Servoless RC undercarriage retracts connecting to Duet 3

      https://www.flyingtech.co.uk//electronics/servoless-retract-metal-trunnion-diy-landing-gear

      I've had the idea to use one of these to flip out a brush to clear nozzles, they can run off 5v and are fairly inexpensive. They run 3 wires, presumably Power,GND & a control signal. I'm hoping I can hook up to an external 5v source with a common ground with the Duet and run the control from an IO pin?

      Does this sound ok?
