Scratch Build – In Progress My Now finished mean Computer Numerical Control machine build

Dodgy mug of Ovaltine again, Tel?

 

Love to know what stuff caused that damn dream

 

O.O Get me some o' dem 'shrooms! I need some "inspiration" too!

 

I had one of those once, but it was because of a refrigerator breakdown. No dreams, only puking.
Please avoid Nexxo's switch ideas. I can confirm how easy it is to make the control unit flip it's lid.

 

Damn, now I regret I never tried good shrooms in my younger years. Did some acid, but we never had access to decent shrooms. #firstworldproblems.

 

Wow. Same here. Only managed to find a good batch but once.

 

Fly-Agaric
If you don't know what you're doing leave these alone highly poisonous



Psilocybin

Let them dry and make wine with or add to an omelette

 

Right a proper update lol

Started getting the lathe work done, there's 4 of these to do machined down to 10mm from 16mm



next the end of the 10mm section has to have a M10 thread on it and the end to be machined to 8mm



This shows all the parts in the motor end, spacer, bearing, spacer, lock nut, coupler, and the motor and of course the motor mount



All assembled in the motor mount.

 

This really is turning in to a monster machine

 

I like those all-in-one bearing/motor mount blocks. I didn't even know they made those.

 

Literally!! Lol - Get it?

Ballscrews came out great man nice work!

 

Was in the dream as well

I was going to make my own but these was perfect for the job so had to buy them

lol yeah just one more to do.

 

Those aren't ballscrews!

/pedant

Sorry.

By the way, what are you going to do about backlash? Those brass nuts don't seem to be of the anti-backlash variety. I've always preferred teflon infused delrin for lower speed hobbyist applications, it'll be interesting to see how you keep friction down with the brass nuts.

 

Yeah I know they are Leadscrews not Ballscrews although I've never referred to then as Ballscrews, as for backlash not sure as yet, oh well oiled

Tbh I may upgrade to Ballscrews later on

 

NO! No more upgrades. Build something with it!

 

SECONDED

Hell, build another CNC with it and ship it to yours truly

 

Depending on what software you use backlash can be compensated for but your leadscrews will eventually wear down a little with brass nuts. The wear can be uneven which makes compensating for backlash harder. Hopefully your nuts have minimal backlash to start with and I hope I'm not being too negative. Everything you've done so far has been great!

If you spend any more money on this we will be forced to stage an intervention.

 

I've not had a chance to get into the software so couldn't say re the backlash. Edit re backlash apparently with these lead screws and nuts I can expect 100 micron the software adjustment method is in mach3 and not very good

The nuts are actually made of Bronze not brass so should be better

Yeah definitely a little over budget now lol in for a penny in for a pound as they say I'm going to finish it even if it the last thing I'll ever do

 

A question of colour

A poll has been added to choose the colour it will be painted please vote
