      @zakfarias ah ok, in that case you could use a mini 5+ for X,Y, Z Z Z and the toolboards for the tools.

      I already have tool-parked switches on the two Hemera tools on my TC. See https://miscsolutions.wordpress.com/2020/06/06/improvements-to-the-hemera-tools. We're considering adding mounting holes for this switch to the next run of Duet 3 tool boards.

      Started reading over some of the stuff you linked, and I'll have to jump on that discord for fun, but man looks like some major evolutions have taken place. Even more exciting to get back into the swing of things with all these advancements! And oh hey I recognize the Jubilee!!! Although back when I first saw it under development it had no name and was just a motion test system.

      Well guess I need to start reading over all the Duet documentation for the millionth time in my life to see what all is new and improved.

      And then try to scour the forum to glean some ideas from others on how they approached some things.
      Still not entirely sold on independent Z leveling either. The idea is great and really does a bang up good job on helping out on some design archetypes, but if you are running 3 Leads synced to one motor with a Mic6 tooling plate bed with thin glass on top you largely will never come out of alignment once you manually level once [and I don't have to worry about the whole IR misreading old print residue/aquanet and messing up first layer performance when I go into production mode (I make small parts in production batches for a few local mom and pop shops still and would like to try and get my hobby business up and going again now that my health is improving)]

      But I am open to the idea of building to be able to accommodate both my normal z setup as well as being able to freely convert to independent Z leveling just to give it a try as long as it doesn't prove to be a hassle to use efficiently.

      @zakfarias i don't have any experience of the sigmax but if you want to see if you can keep the features tou like then break them down into steps that releate to individual gcode moves and confirm you can write macros for those. Some of those macros will probably be RepRapFirmware system macros in the end - like homing or tool changes, others will be custom user macros (like determining tool offsets).

      I'm curious to know why it seems like these designs use smooth bearings against the toothed side of the belt instead of a toothed pulley as an idler? Preferably the same size as the pulley as on the motor.

      Halogen lights are very effective at heating with the additional benefit of adding light. You can buy the cylindrical type and a dimmer to control/set the intensity at home improvement stores. I solder the wiring directly to the contacts to avoid having to add receptacles.
      There's a link to a NASA project towards the end of this article using halogen lights for heating.

      Wouldn't feed hold be equivalent to using pause/resume with empty pause.g and resume.g files? That wouldn't be desirable when 3D printing because you would get a blob or worse.

      It sounds doable if you can get the mechanics of print removal working reliably. You can configure the arm as another axis. The emergency stop can be implemented by the RPi feeding a signal to a spare endstop input.

      However, I advise against leaving any 3D printer unattended for more than a minute or so without a remote power cutoff mechanism and fire extinguishing system.

      OKAY So I ended up adding the M400 and then for fun said screw it and got rid of all the M300. Works like a charm now! Also dialed back the additional retraction to 2mm. So at least the heater safety issue seems to be resolved

      Firmware is 1.18 release on 04/09/2017. I am upgrading to the new 1.19 release currently.
      ; Heaters
      M143 S290 ; Set maximum heater temperature to 290C
      M301 H0 S1.00 P10 I0.1 D200 T0.4 W180 B30 ; Use PID on bed heater (may require further tuning)
      M305 P0 T100000 B4408 C7.271094e-8 R4700 ; Set thermistor + ADC parameters for heater 0
      M305 P1 T100000 B4725 C7.060000e-8 R4700 ; Set thermistor + ADC parameters for heater 1

      Here is config override:
      ; Heater model parameters
      M307 H0 A101.8 C152.3 D5.0 S1.00 B0
      M307 H1 A271.6 C123.4 D4.0 S1.00 B0

      On the bed parameters I believe it is supposed to be a B value of 3950, I am just inputting the data from Keenovo's R–T spreadsheet for 25, 50, and 100 and that is what it spits out

      Heatbed is a 110v 300mmx300mm keenovo
      hotend is E3D-V6 [note: this is the only hotend I run on all my machines(except Rostock since it hasn't been commissioned to work stock even)] So hotends are identical across all machines.
      I am wondering how there could be a leakage with an all new Board, shielded wiring, and spare hotend that I installed this past weekend? I did do the voltage test as suggested on the old board but forgot to post. Just checked new board (3.9-4.1mV) while at 200C.
