After a couple months of getting my Merc in working order, I've developed a backlog of improvements. With my BL-Touch probe deciding to suddenly unalive itself, now seems like the perfect time to get it all done at once.

Agenda for this teardown:

  • Install Wagos and 12ga wiring for all 110v and 24v connections and rearrange my electronics.
  • Move my power plug and switch to a more convenient location.
  • Rebuild my toolhead with all new parts in prep for my MMU build, adding pre and post extruder filament sensors and a filament cutter to my E34M1.
  • Crimp a custom USB connector between my Beacon and Nitehawk36.
  • Upgrade to metal stepper towers.

Got the enclosure topper that was hiding my rat nest removed, and got all my 24v wiring redone in 12ga and Wagos. Need to order some spade connectors for the 110v connections. Added a powered USB hub and a USB power isolator so I don't blow out my Beacon by plugging it into the M8P. Just have to get a shorter USB cable for my Wyze webcam, and some 2020 clips printed out to clean it up a bit.

Looking into alternative fan mounts for both the M8P and the RSP-500-24 so I can fit a top on the enclosure.

Did a bit more cleanup with 2020 cable clips, fairly happy with the setup.

Tomorrow I'll start pulling apart the toolhead and the stepper towers.

Reverted back to the stock PSU shroud, just have to figure out a good low-profile fan solution for the Manta, and I should be good.

Got the new filament cutter toolhead prepped and the base body installed. I did a dry fit for the orbiter with the pre and post extruder filament sensors, and with a bit of reaming and a ton of PTFE tube cuts, it feeds all the way down to the hotend smoothly with no catches using multiple cuts of filament.
