I just got the quote for extruded MegaRail.
Based on that, it seems the retail price of MegaRail 80 will be £40 for a 1 m length, and MegaRail Z will be £4.50 for a 250 mm length, or £12 for 1 m.
To compare, this is how much the rail for a 1 m × 1 m gantry-style CNC router table or milling machine would be:
- 4 × 1 m MakerSlide (for a dual-rail gantry) + 1 × 250 mm MakerSlide: £52
- 3 × 1 m MegaRail 80 + 2 × 250 mm MegaRail Z: £129
I would say that’s not a bad price for the huge increase in rigidity.
MegaRail Z will be available in 250 mm (to be determined: could be 275 mm), 600 mm, and 1000 mm.
MegaRail 80 will be available in 600 mm, 1000 mm, 1500 mm, and 2000 mm lengths. I’ll try to get 2700 mm lengths too, but those would ship only within the UK.
Assuming reasonable carriage widths:
- A machine with a 1500 mm gantry can cut the entire width of a full sheet of plywood, MDF, or chipboard (2440 mm × 1220 mm). With indexing, it can cut a whole sheet in several operations:
- a 1500 mm × 1500 mm machine can cut half a sheet without resorting to indexing, or an entire sheet in two operations;
- a 1500 mm × 1000 mm machine can cut a third of a sheet in one go, and it can still fit a whole sheet through and cut it in three operations, with indexing;
- a 1500 mm × 2700 mm machine, if it ever became available, could cut a full sheet in one go.
- A 1000 mm × 1500 mm machine can cut a third of a sheet of plywood, or an area the size of an A0 sheet of paper (but a slightly longer and narrower shape than A0).
