Bloody hell Jo that would have tickled bit if that blade caught collet spun up . .:dejection: . . .
Haha yep just finishing it now and that thought did cross my mind. But the only thing touching the saw blade is the bushing so I figure it's safe enough!?

OK folks, finally finished the NEMA 34 mount tonight. Pleased with it, and quite pleased with the final video I've made about making it! No more routing with the circular saw blade now Jazz, I promise! https://youtu.be/nbmGCuirTy4

Joe nice vid, Are you sure that the motor is seating in the mount properly I am not sure but it looks like there is a gap between the face of the motor and the mount.Quote:

For anyone interested I have uploaded another short video showing some z axis progress to YouTube: https://youtu.be/nBGU28XVHdA

I love your videos, you are a great inspiration
Thanks!Quote:

Hey Joe,
Sorry for hijacking this thread, but how do you print your schematics that you use to centerpunch your drill holes (your youtube video of Z axis plate for example)
When I try it comes out the wrong size. Tried printing from solid works, exporting to pdf then print and exporting to dxf then print.. nothing seems to work perfect :)
Ah, guess it depends on your printer? I use the big HP plotter at work which is accurate to a fraction of a mm...
I found the laser printer to be pretty inaccurate maybe because of the heat? What are you printing with?
I have only tried the laserprinter at work.. might be the problem :) will try a printshop maybe! Thanks!
I take it you are printing the scale as 1:1 and not fit to page!!Quote:

Now I get something like 16.8 :(
Well there is something wrong as even with a bad printer it should only be about .5mm out.Quote:

can you post the dxf up here and I will try and print it for you or adjust it in Acad
Ok edit: I have printed out in SW direct from the part on screen but you have to go into "file/print" and then page setup my printer shows "scale to fit" and "scale "100%" choose 100% It works for me.
Will try with new settings, maybe I have a scale error in the printer setup! If I can't get it to work I will pm you with the dxf Clive :)Quote:

Hello everyone - bit of progress on the z axis... need to revisit the circuit diagram, the mechanical stuff is getting close now [emoji846]

Following on from the pictures in the previous post above, another short video of the dry run assembly of the z axis below: https://youtu.be/_0nJBaUaBBA
I still need to make the bracket which fits between the top bearing mount and the z motor mount, the bottom bearing plate and the front z axis plate where the spindle will be mounted.
I'm going to open up the holes on the plates which pull the z bearings forward to allow better alignment. Align them with one another using the dial indicator... the problem is then I cannot get to the bolts which fix the vertical plate to the bearing plate to get that adjusted - wish I had foreseen these problems when designing the thing! Nothing some shims can't fix?!

As always Joe love the music and the vid. I think this is one of he best router builds on the forum It puts all the wingers to shame. Thanks for the entertainment :congratulatory:
Cheers Clive!Quote:

Joe, that's one mighty fine looking CNC machine, I've enjoyed the build so far and now looking forward to seeing the first chips flying in the not too distant future!!
Thanks guys, getting there!!

Oh shit just realised didn't reply to your message, sorry Jo slipped my mind will do later today.
No worries at all! Whenever you get a minute - no hurry!!Quote:

For a P14-5M-15F, for example, with an 8mm bore, you can get 1 or 2no. M3 or M4... I'm thinking 2no. M4?? But the P28-5M-15F for my NEMA 34 which will have a 12.67mm bore and a 5mm keyway can go all the way up to 2no. M8 grubscrews which sound huge!? Any thought from those who have gone before? Cheers

2 x M4 on the small ones, flats on the shaft and flattened bits of copper (Clive's tip) under the grubscrew tip and a single 8mm over the keyway...

Won't be long then Joe!

Just curious.. what's the copper tape for? :)
Joe Have you decided what drives and controller you will be using? Looking forward to the box build:eagerness:Quote:

Hello!
Time for an update.
So I've done a bit more work on the z axis and you can see progress on this here: https://youtu.be/mWTSq0ZqsLE
But my main focus has been on getting the electrical side started.
Many thanks to Dean and Clive who have both been super helpful and now I think I have a workable circuit diagram which I feel happy to share on here. A word of caution to anyone just getting started, please do not follow this verbatim, there are no-doubt some mistakes / things I will change as I go and as with drawing out the mechanical stuff before you start, you need to do this yourself to get your head around what you are doing. That said, I'm more than happy to receive comments from experienced members, particularly if you spot any dumb mistakes.
I now have, or have on order, all the electrical bits and bobs, cable, ferules etc. apart from the big ticket stuff -the drives and controller which I am leaving as late as possible. I also need to figure out what current rating I will need for the 24V supply.
Really excited to start this part of the build finally!
Cheers everyone.
