Step 13.50 — Bolt both brackets to the bed extrusions¶
Step 50 of 54 with a helper · Chapter 13 — Initial startup
(no image — see text)
Parts:
- the brush bracket with its bucket · already on the bench
- stop bracket ×1 · bin 13-scrubber
- M3 roll-in T-nut ×4 · Fasteners, Tools & Misc box
- M3×8 SHCS ×6 · Fasteners, Tools & Misc box
- 2.5 mm hex key · tool
Do:
- Power on,
G28,G0 X175 Y60 Z150. Roll two T-nuts into each extrusion's top slot behind the plate. - Bolt each bracket with two M3×8, face on the plate edge, snug.
- Fit the upright M3×8s unless the printout said no.
Check
Both brackets sit flat, front faces on the plate edge. With the stop screws fitted, the flex plate stops on both heads.
Helper Holds each bracket against the plate edge while the adult tightens it.
What you're looking at
Both brackets sit on the bed extrusions just behind the plate, their front faces against its rear edge. The brush bracket goes on the left, away from the nozzle-probe pin. One upright M3×8 in each bracket is a sheet stop.
Caution
If the right bracket touches the probe collar or body after all, take it off. A pin that cannot move freely drifts Z zero.
Good stopping point · ~25 min since the last one
the add-on is bolted on, the bucket hangs on its magnets, and Klipper does not know about it yet. Do not run any scrub command before Step 13.52.
