Linear rails are far superior to round supported rails.

Had a productive day or two... apart from some minor things left to do, the Z-axis is now completed.

First up I made the top counter bearing plate. I had planned this to be 10mm but I only had...

Sorted out the ball nut greasing arrangement... So obviously I didn't fancy stripping down the whole thing every time the ball screw needed a bit of grease. I came up with this solution:

Made a...

6.8KW 24K RPM Spindle. Works well, had some issues earlier but sorted now.

Decided to re-vist my original plans for a belt tensioning system.

I whipped up this design

And then set about making it. The idler I made from alu tubing...

More work done today... Didn't have any suitable materials for the counter bearing plate so got cracking with some of the other stuff!

First up, 6mm spacer for the ball nut mount to make it reach...

I know.. I know!
Should finish the machine but playing is sooo fun :D

Made another free vectric project ;)

Turned out real nice!

Skickat...

Oh that's pretty neat! I can add it to the long list of projects lol...

Enough of this manual lathe nonsense, today I fired up the CNC at last and made the top plate for the new Z-axis.

First...

Yes it is!!! I made a dust shoe top! Getting ready to try the bottom here in a few.

Camel toe.......


Sorry couldn't resist ;)

I can't remember of hand what language Mach 4 uses, but it's not the same as Mach 3.

Mach 3 used a form of basic, whereas Mach 4 uses a scripting language of some form.

First cut! The requisite circle :)

Still so much to do, but that is definitely encouraging!

Thanks Dave. Yes, glad I managed to squeeze two steppers on the Z axis. It is too heavy for my scales so I need to find a way to weight it. Certainly picking it up is a challenge (and there is no...

NO 100% NO the sooner you learn the Software side the better, both Cad/Cam and controller. Think of it like giving a Kid toy for Xmas without any batterys.
Nothing worse than having working machine...

First movement!!!

Well he said it had something to do with a bulk order from a client and complaints about resistance from double seals and getting things mixed up.

Anyway i am glad i bought from him instead of...

Actually, I have only experience of PP BOBs.

I bought this beast because it was cheap and I intended to use it for my current machine and/or the next build, but various bits of my life got...

If you are spending all that much on the motors and drivers, then I would go for a proper motion controller not a Parallel port BOB.

Yes exactly that.
There are four main advantages to servo over a Closed-loop stepper. #1 Speed #2 torque #3 Smoothness #4 Resolution
But what you really have to do is examine the differences and...

Glad it's working today - computers eh!?

Glad you are enjoying the videos although I've got a thumbs down on the latest one already. I guess you can't please everyone. It would be good to know...
