    • RE: What Insulation do you use?

      I extensively use self adhesive foiled rubber foam. Its the stuff that comes sometimes with heated beds for insulation. Its actually manufactured as automotive engine bay sound and heat insulation. In my opinion this knocks the socks off all other options. Easy to install, cheap and very effective. My enclosures are all passively heated and achieve 74degrees consistently. Heres the aliexpress link. https://www.aliexpress.com/item/1005001475455913.html?spm=a2g0o.order_list.0.0.21ef1802dXxfYm

    • RE: Random additional steps - interference?

      @phaedrux The stealth chop point seems potentially likely as the good printer is running RRF3.3 on Duet 2 spreadcycle and bad printer is 3.4 on big dipper TMC2209 defaulting to stealthchop with a weird speed threshold that switches to spreadcycle. This sounds like it can give rise to inconsistencies.

      I'll change the M569 to enforce spreadcycle and report back. Fingers crossed.

    • RE: Tool Length Switch

      @phaedrux said in Tool Length Switch:

      ou should be using the probe to set the Z position

      I'm a little confused. I am trying to achieve a setup that ignores the induction probe z offset entirely and relies only on the tool length switch. Indeed the voron guys don't even bother accurately setting the induction probe trigger height in the config as they don't use it. The probe is just used to create the contour (delta z) map and the switch to set the global height. My goal is to avoid the heat drift problem with probes.

    • RE: Random additional steps - interference?

      BINGO! I turned off the default stealthchop and enabled spreadcycle via M569. Completeley solved the problem.

      Default Stealthchop switches back and forth between spreadcycle and stealthchop when the speed is low. This seems to create a print blemish when this happens. My advice is STICK TO SPREADCYCLE!Main Lathe Clamp-01.jpg

      @oliof That's incredible. I'm more thinking of the engineering applications more than art though!

    • End stop indicators on DWC?

      Is there a live way of showing the end stop status on DWC. I realise there are LEDs on the board but it once installed in a housing at the bottom of your printer they're not much help. I am trying to diagnose a problem whereby the x axis is intermittently not homing. It behaves as is the end stop is already triggered.

    • Stops dead randomly

      My duet 2 mini 5+ controlled printer has recently developed a problem whereby it stops dead randomly. I have yet to catch it when the failure occurs but it appears as though someone just cut the power momentarily. Could it literally be a fault with the power supply? I have attached a shot of the console that may indicate something. Any ideas?screen.jpg

    • RE: RRF on Bambu Labs etc.?

      @oliof Yes, I hear what you are saying with regards merits of semi industrial type machines. Cost is a big factor however. I need maximum user serviceability, ability to print ABS in a 65degree chamber and strong mechanics/motion system for print quality and reliability. Speed is irrelevant.

    • RRF on Bambu Labs etc.?

      I was wondering if it would be possible to run consumer machines such bambu Labs P1P or Creality K1 with RRF. I run a small printer farm based on my own custom printers and prefer the total control of RRF. Of course I would expect you will need to replace the board and screen with say duet 3 mini but can reprap be used to control all the hardware including strain gauges etc?

    • RE: PL-05 Type induction probe with BAT85 diode

      @dc42 Yes that's correct. The PL05 does not work with less than 5v hence using the expansion port. Does it matter where I connect to GND? I was wondering if it made a difference using the GND on the z probe port or the pin2 GND on expansion.
      Although it seems to work ok on the 5v so far, I was thinking of taking 24v directly from the power supply as the probe does indicate 6v - 30v. Are there any issues doing this? Which GND should you use in this setup?

    • RE: PL-05 Type induction probe with BAT85 diode

      @dc42 Hmm. Does that apply if I use the 5v and GND from the expansion but signal goes to z probe in. I have a v1.04 duet 2 wifi.
