Hey folks,

I need help with the alignment of my linear rails.

The planned system is illustrated below.
- 2000mm x 1360mm ( 40x80mm aluminum bars; connected with angles )
- Linear Rails: Two HGR15 linear rails ( yellow ) with two carriages per rail ( dark grey ), connected to 40 x 40 mm aluminum profiles using self-drilled 10mm thick plates
- this setup is for a pick and place robot with minimal operational forces beyond acceleration, utilizing a Core-XY rope drive.



My assembly plan is as follows:
1) Lay aluminum bars on a PVC floor to ensure a level base.
2) Attach the rails loosely.
3) Move the carriage to one end, tighten screws between the carriages slightly. Repeat on the other end.
4) Continue tightening screws in stages, moving back and forth, until all are secure.
5) Repeat 3) and 4) over and over, giving all screws an extra quarter turn, until they are tight.
6) Stand the construction upright.

I will be frequently laying down and standing up the construction after completion. My concerns are:
a) Will this process achieve proper alignment?
b) Can the alignment withstand the frequent repositioning?

Appreciate any advice or insights.

Thanks,
kis-mat
