Luke11CNC Build Log ,I'm so naïve

[Web Goblin]

Looking good so far. I would add some cross supports near the bottom of the legs on all sides to prevent any movement. The natural movement of the drives will cause the frame to sway and you dont want that to happen.

Yes definitely, and some triangulation wouldn't go amiss.

[luke11cnc]

yes that is what the extrusion is for against the wall and Four more 45x45 on the bed

[luke11cnc]

bits have arrived BUT I'm waiting for Luke to come home so HE can open the package

sorry lad's and girls (if any) but this is a Father and son bonding project

I will post images of items when Luke gets home

He is at work with the wife until 2.00 pm

Here's the brackets I've made for you:









Unfortunately it's 4mm aluminium not 5mm. I was told it was 5mm and didn't check ... hope that's ok

[luke11cnc]

they look the dog's b's Jonathan

thank you

well the ball screw ends where a bit tight.
The big bearing end had to go in the oven and be persuaded with a big adjuster (lump hammer and a socket) but now the lock nut at the end will not go on (yes) i must of caught the thread when I had the persuader in action

not to worry I don't think it's going anywhere or should I have it rethreaded :question::question:

James and Luke

we are going to start bolting down the supported rails on Sunday:rofl::rofl:

It varied between 11.992mm and 12.000mm depending on where I measured ... so a slight taper.

Typical, I'd try it and see. If they don't fall off then no problem. On my RM1610 ballscrew (Y-axis) I had the opposite problem yesterday - the bearing was not as tight as yours and I must have not done the nut up tight enough...took me ages to work out what what causing the Y-axis to loose position.

not to worry I don't think it's going anywhere or should I have it rethreaded :question::question:

Bigger spanner!! But first check that the two grubscrews in the edge of the nut which lock it in position are out. Also check the pieces that the grubscrews push onto the thread are not interfering as if they've rotated a little they will stop the nut. I had that problem on one of the nuts that came with the RM2510 ballscrews, so a bit bigger.

I've made the extra 4 brackets - 8mm holes and better finish this time. Couplings almost done too...

[Jonathan]

More brackets, the two couplings and the ballnut mount (finally) done:





(Sorry they're a bit blurred - the camera wont focus for some reason)

[Jonathan]

It's been almost a week... how far have you got?

I've done the rest of the brackets.
