Step 02.10 — Optional: fit the LDO rail stops at the top of each Z rail¶

z_rail_stop_x4×4 · bin 02-Z0, 02-Z1, 02-Z2, 02-Z3
Do: Fit a stop to the top of each Z rail now, while the rails are accessible. Skip them and the tape from Step 02.08 covers you until Ch 06.
Check
A stop on each of the four rails, or a decision to skip them with the tape left in place.
What you're looking at
The grey render is the LDO rail stop, a printed clip that caps a rail's top end so a carriage cannot run off during the gantry install in Ch 06. It clips to the free top length above the carriage.
Tip
LDO also uses a rubber rail stopper under the Z joints as a gantry rest at manual p.114–116. That is Chapter 06 — do not confuse the two. src
Tip
The CAD rail is MGN9 300 mm on a 430 mm vertical, leaving ~107 mm bare above it. The stop clips to the rail end, not to a dimension.
Good stopping point · ~35 min since the last one
all four Z rails are on, facing each other, sharing the same ~3 mm bottom gap and hole pattern, every carriage taped or stoppered. The frame is still the right way up. Do not turn it over until the carriages are secured.
