big budget cnc

[pet30]

i made some modifications

the profiles are 80x80x 5 mm think,my metal shop not far from here has got a lot of them.

for the gantry:

a beam of 80x80 then 80 mm high pieces on the beam and again 80x80 beam
on the back of the gantry 80x80x160 mm pieces welded against de total gantry to make it more stronger and less abel to flex.

because i will use r&p i was thinking mouting it on the gantry on top.
then on the sides 1 stepper motor in the steel beam 80x80( to save more space) and 1 just hanging on the bottom against the rack ,
thats mounted against the 80x80 3 meter steel beam.




What do i need to change
the router i will be using in the beginning a bosch router but in the future probably a spindle.
the bosch router ways about 5 kg.

You could do with modifying the rack mounting arrangement on the the high X axis, it's going to get clogged with debris if you have it as shown.

Also make the point where the gantry supports join the rails wider and get the spindle centre central to the bed-rail bearing blocks.

I'd consider buying this and importing it I think it'd cost ~€1200 to Germany but it might be too big for you. I know someone who would moves this no probs if you'd be interested have to get a quote.

Needs work but seems a cheap way to get a decent 8*4 router

No its to big ,

i have max 3000x1800 mm if i go 2000 mm then the car can't go in the garage.

should i make a metal frame for the cnc or can i make a wooden frame and bolt everything ?

Metal frame, really wants to be steel at that size but if you do use T slot aluminium you need chunky profile and I would have it predrilled so it bolts together rather than T nuts. I'm certain you can make it fold to the wall for extra space (Although not the machine I linked to lol) It will cost a lot more to make it from aluminium rather than steel, I lack the confidence to weld a steel frame for a cnc so i would use a coach builders to make my frame.

Or maybe it's time for your mum to take up motorcycle riding ;)

That used machine looks very promising.
