Step 05.48 — Log the measurements¶
Step 48 of 48 with a helper · Chapter 05 — Gantry: X and Y axes, XY joints, X carriage, titanium backers
(no image — see text)
Parts:
- pen · tool
Do: Record the rail overhangs you measured, Y and X at both ends, the two Y-to-Y spacings, which face each backer is on, and anything you left deliberately loose.
Check
Numbers written down, not "looked fine". You will want the Y-to-Y spacings when the gantry is squared in Ch 06.
Helper Writes each gantry measurement into the log as you call it out.
What you're looking at
The paperwork you will want in Ch 06. The rail overhangs are the evidence that each rail is centred; the two Y-to-Y spacings are the baseline you measure against once the gantry has been squared in the frame.
| Measurement | Target | Yours | Notes |
|---|---|---|---|
| Y rail overhang, extrusion 1 — end A / end B | 25 / 25 mm | ||
| Y rail overhang, extrusion 2 — end A / end B | 25 / 25 mm | ||
| X rail overhang — end A / end B | 15 / 15 mm | ||
| Inside Y-to-Y spacing at the bridge | — | ||
| Inside Y-to-Y spacing at the idlers | = at bridge | ||
| Backer face — Y1 / Y2 / X | top / top / rear | ||

Good stopping point · ~25 min since the last one
gantry complete and still upside down (motors up), measurements written down, Ch 06/07 parts bagged and labelled. Do not tension belts and do not square the gantry: both are Ch 06/07 and both would be undone.
