Mood. I have a dozen stalled projects waiting on me to calibrate my 3D printer after I upgraded it (another project).

One of these days I'll finish my whole home HAL9000 project.

Can you break up the calibrating process into shorter steps? I'm mostly unfamiliar with 3D printing, what's all involved?

Kinda, but they all need to be done before I can start printing again. I replaced the entire hot-end, so I basically have to redo everything:

  • Rotation distance (distance traveled per one rotation of motor)
  • Hot-end PID calibration (controls heating)
  • Z-offset (how far above the bed the nozzle is from when the z-stop triggers)
  • Resonance compensation (printing fast can cause ghosting in the prints from resonance frequency)
  • Pressure advance (reduces nozzle ooze)

And all of that is just so I can print a mount to use a magnetic z-stop (normal is contact probe), then I get to do it all over again.

Then I need to do temperature and acceleration towers for each filament material.

that touch sensor is very good to make sure you don't need to calibrate z offset. saves you from having to fiddle with it, and always makes perfect 1st layers. excellent upgrade.

Must the magnetic z-stop mount be printed on your machine specifically?

If yes; do a calibration step or two each week and you'll be done by xmas

If no; print one at a local makerspace/public library then do a calibration step or two each week and you'll be done by Thanksgiving!
