      You can't really check for the existence of a variable.
      The null object in the object model doesn't support that usage.
      You just have to define them once the use SET thereafter to modify them.
      Trying to define them again will give a console error but no other ill effects apart from any value you used in the second attempt (probably) won't be applied.

      I know I read that most pins lead directly to the MPU but others were 30V-tolerant (like the z-probe_in pin or endstop pins?) or somehow protected with diodes. Problem is to find that particular Wiki article. Important informations are very clustered sometimes.
      Maybe that wasn't a description of Duet2, but Duet3?

      @arhi
      It only makes sense to spend more money than a BLTouch would cost, when the result is equal or better.

      To me it would make sense investing time if it would solve a problem that exist and is not solved. TBH I don't see what unsolved problem this could solve except to work as underbed probe. ATTM I don't know of reliable underbed probe. Probing from the top, I doubt it can have smaller footprint than some piezo/bltouch/easytouch/.. sensor .. and as for precission and repeatability a simple microswitch is "good enough" so

      but a real winner would be the heatsink-necklace as it has zero offset and requires less force than piezos.

      I can't visualize how would this work

      Thanks for the warm words.
      The Slider is pretty small and I will mount a hotend with Bowden extruder at most. The hole pattern is 20x20mm.
      But the concept is scalable. You can use bigger Delrin or PTFE rods to beef it up.
      A few years back I tried to build a Delta printer with such sliders, not sure why I stopped.

      I just noticed, I had RRF3.3.b2 running, but DWC is still 3.2.
      Could this lead to unexpected behaviour, like echos of previous reboots popping up
      Will upgrade ASAP.

      I spent the whole day to calibrate the dual extruder setup with tool changes and Slicer settings.
      Tuning the Z- and X-axis was easy, but the Y/V axis puzzles me. I had a very good calibration-grid, then printed a dual color testcube which showed signs of overextrusion, but was 'spot on' otherwise. The next print should've been an appetizer to show off, but there was an offset in Y/V again?

      I'm too tired now, will see how it behaves tomorow.

      I'm glad I started learning IDEX printing on a fun project where it doesn't matter when things go wrong.
      Running a testfile I paused the print and changed tool. The tfree macro worked as expected, but after hitting resume both axes were moving for a moment. I guess the print queue wasn't empty?
      OTOH, when I send T0 or T1 without pausing, everything works. I know there is a M400 wait until printbuffer clear, but where do I put it?

      @dc42
      I used the configurator tool to generate my config.g. When I defined the tools without fan the configurator adds a "F-1" to M563.
      But RRF3.3b2 doesn't accept that and throws an error, when running M98 "Pconfig.g".
      Something like "expecting a numeric expression after 'F' param"

      Maybe I' m the first noticing that, otherwise ignore it...

      I designed a panorama frame and tried transparent PETG. It seems, Velocity painting doesn't like Arc Welder, or pressure advance, so I switched both off and got a pretty good result.

      The frame is on thingiverse

      @vishiano said in Simultaneous printing with collision zones and semaphores:

      Could this be taken one step further and allow for two printers to print simultaneously off a single board + expansions?

      @dc42
      I would also opt for independent controllers, because they would each have their own Z-probe and mesh leveling.
      Right now, there's only one Z-probe allowed AFAIK and independent mesh leveling is important when two tools work at different places.
      My proposal was to use a mini-Z axis on each tool for height adjustment and Z-hop.
      Your new approach has means to implement that, too?

      @fma said in Texture mapping with feltpen carousel?:

      I plan to make tests with pens, as Make Anything did; it is a very easy setup...

      I already figured out, only 'permanent markers' stick to PLA.
      I think, I've seen the video and their process is not able to produce real textures.
      You'd have to dye the filament with a timed process. I'd better like to steal the mapping algorhythm from "velocity printing" and rewrite it to add ink layer by layer.
      I don't expect perfect results, but a powder printer with inkjet is a bit above my budget..Let's see how bad it is..

      Prusa MMU2

      That MMU2 is a funny thing. Reminds me a bit of a photoshopped 5x Wade extruder I published 2015:

      5x-wade_small.jpg

      The interesting part is the ramming and the cooling moves I hope to have the chance to try out without having a MMU2.
      But first off all, I have to disassemble my hotend to remove the Jam and do some failure cause research.

      It's a Conductive probe (NPN & NO) I've used it before with little to no problems (except the temp-related failure in a heated chamber)
      LJC18A3-B-Z/BX also works on wood and other materials.
      Which is the reason, why I had it on my CNC as well.
      (try DC42's mini IR probe on shiny metal, just for fun...)

      Good point, I'll make a testprint with a part placed along the rail in question. It's also a good ringing test.
      The belts are all on one side, I hope that keeps the extruder-mount from twisting, too.

      @Veti said in Dual extruder with ABS and PLA?:

      no necessarily. look at the bmg.

      I'd be tempted to use two orbiters
      AFAIK, the SLA version 1 is avalable in a mirrored housing.
      But I'm afraid that the later versions made by injection molding, won't be availabe in mirrored. At least I haven't seen them yet (V1.5)

      @deckingman said in Dual extruder with ABS and PLA?:

      Why use PLA as a support?

      Because lately I asked abut the chance to mix parts from PLA and ABS. Someone said, they won't bond and actually the materials are often used as part/support combo.
      I wanted to give it a try...

      Not so sure about ABS anymore. My capacitive probe doesn't like either the chamber temp or bed temp, I'd need for ABS.
      So I'd have to home cold which I don't like...
      Are their other probetyps less temp-sensitive?
      I also have dc42's differential IR probe or inductive probes (which I replaced with capacitive for a reason I forgot)

      BTW: your CoreXY has a similar Z-axis than I have

      I recently modified my z axis to make the motor mount more rigid to stop some bouncing I was having with the printed mount.
