operation cnc

[kingcreaky]

ok taking on board jonathons comments; ive redesigned Y gantry to bring Z closer. feelings on this?

ive also taken the sound advice of a very nice chap; who pointed out I should add some extra bracing at the top to reduce resonance; At present I can only guarentee space for the yellow peace... I need to think of a cunning place to put one at the other end. the obvious place would be between the two 60x100's however that is going to be RIGHT in the way

Ive also added the red-blocks... the idea of this is to support the bed bolts further. Its suspected the bolts will move and the bed will constantly go out of true. Therefore the idea of these is to re-inforce.

however, ive since had a brain wave.. stand back. the idea of the multiple holes on each leg is so the bed can be lifted and dropped. well... how about instead of the small red peaces; I have 6 metal peaces pre-cut same length per height adjustment... so imagine the red bit going all the way down to the horizontal cross bracing.. only drawback to this idea is that I need 6 bits per desired hieght; but the advatage is the plunge force onto the bed is directed down onto the horizontal beams (which in the drawing are represented as 30x30; when infact they are 60x60x4's


eagle eyes amongst you will also notice ive switched the Z screws round (so the belt and stepper is at the other end).

anyway; been building cnc all day yesterday and new shed all day today (long story) in the freezing cold; Time for a beer and to fall asleep in front of the telle

work tomorrow.. dredd.

Who can I Pay to supply cut and machine all ali plate bits for the Z and Y this side of xmas? none of them are complicated no pocketing. just straight cutting (well straighter than me and my angle grinder can do!)
