its a start (8x4)

[reefy86]

Hope i ain't being a pain to some of you guys as i do tend to ask a lot of question lol. i really hope this goes far and i do have the budget for it but patience is key in this hobby and one i am looking forward to doing.

so machine size in total is 2m wide x 3m
cutting area is 2440mm x 1220mm

frame is made out of 100x100x5mm mild steel with 10mm steel plates for the rails and will be sent off to be machined (quoted £900 for machining and probably an extra couple hundred for transport)

z axis is 560mm long for the front movable plate 30mm and 450mm long for the back plate with fixed bearing blocks both 30mm thick and the bearing plates for the y axis is 20mm thick.
2x 550mm 25mm hiwin rails (was going 15mm but not that much in price difference so why not)
420mm long tbi sfu1605 ballscrew using htd 5m 20t 15mm wide1:1 ratio

y axis is 1820mm in total with 2x 80x120mm aluminium profiles in a L shape with 30mm thick gantry side plates. the aluminium profiles have 2 20mm plates each side 1 that bolts to the x axis bearing blocks and the one that bolts do the aluminium profile (gantry)
1x 1450mm tbi sfu2020 ballscrew with a 2:1 ratio
2x 1450mm hiwin 25mm rails

x axis is 3000mm long in total with 2x 2700mm 2525 ballscrews (bst doesnt seem to show they have these in the tbi range) with rotating ballnuts also using 2:1 ratio
2x 2900mm 25mm hiwin rails


weight of gantry is roughly 95kg (not including ballscrew, rails, motor and motor mounts so probably touching over 100kg )

ive not had a chance to look at the motors yet but looking at the either the closed loop nema 24's 5.5Nm or 10Nm (looking for recommendations with the above spec)

looking forward for the advice..

thanks guys
