Step 05.44 — Run the X axis end to end¶
Step 44 of 48 with a helper · Chapter 05 — Gantry: X and Y axes, XY joints, X carriage, titanium backers
Tap to enlarge
Parts: none.
Do: Push the X axis slowly end to end several times, a hand on each XY joint. A tight spot means a rail is not centred; rising stiffness means racking. Do not loosen rails to fix it.
Check
Full travel both directions, no notch, no rising resistance, both Y carriages moving together. Racking is normal and is corrected in Ch 06.
Helper Slides the X carriage slowly end to end and reports any rough spot.
What you're looking at
The first real function test of the gantry as a mechanism. Even, light resistance the whole way means both rails are centred and both carriages sit square. Resistance growing towards one end is racking, a Ch 06 problem, not a rail problem.
Good stopping point · ~30 min since the last one
gantry upside down (motors up), X axis in and bolted to both Y carriages, running end to end without binding. It stays upside down into Ch 06. Belts still bagged, XY joint bolts still only lightly tightened — leave both alone.
