Warco Wm14 Thread

Oh cool, everything came from eBay, all of the electronics including the stepper motors came from the same seller, longs motors: I bought the kit shown below:

I got the three ball screws from a different seller ckswin, they can well packaged and look to be in good condition. I cant comment on accuracy until they are installed. £75 for all three. I couldn't find a 12mm ball screw in the length I wanted on eBay so used aliexpress that was £50 including bearing blocks and ball nut holder.

Couplings eBay from China.

Everything had a sort of 2-3 week turn around which gave me time to plan and think about what I needed to do.

The only thing yet to arrive is the bearing blocks for the 12mm ball screws which apparently shipped from holland (I choose them based on location) they were ordered from this guy and still haven't arrived 805841b13065cbe65d0e57ffec70051a.jpg

Thanks very much for the info, much appreciated! Hope the bearing blocks turn up soon, it's going to be fun seeing this come together.
 
Thanks Matabele The bearing blocks turned up on Thursday butI haven't had a chance to get in the garage yet apart from to size them up quickly, need to sit down and plan out the next bits to make and then get the x and y axis done. I'm a bit nervous about the z axis as I haven't even had a look inside the support yet so not sure what sort of challenges I might face!

Spent the day in the garage yesterday getting some more work done. I decided to mount the ball nut on the outside of the saddle as I have a bit of extra length in the ball screw. Another factor is that I want to avoid as much as possible altering the original parts. Here's a few images sizing things up and trial mounting. (Btw please let me know if these images come it ok, either too small or too large as I do this all from my phone)

Y axis mounts complete

And mounted on the mill

Mount for x axis ballnut

Again for the x axis I used the bandsaw to chop the ballnut mount down to fix in place, put two m4 bolts in there, cut them down to size and countersunk them in the mount

These still protruded enough to get in the way of the table so I have marked them where I will machine them down further once the mill is back together!

I plan on doing some more tomorrow hopefully enough to get both x and y axis complete

X and y connected and tested, I've not put a video up before so hopefully it works, just returning the table to zero after playing around...

Things still to do:

Take a look inside z column to see what pleasure await

Make a proper y axis ball nut mount

Reload the x and y axis ball nuts with any bearings that I didn't find earlier

Learn how to use Mach3 properly and buy a licence, I'm on the demo version at the moment.

I will probably end up remaking all of the mounting plates as a first project

It's been a while since I updated this thread but with a newborn and a cnc machine to finish I've been a bit busy!

Needless to say I managed to use some time whilst baby was napping to finish off (the basics) for my cnc machine, the z axis is complete and working as expected! I'll take some photos of the finished item but unfortunately didn't have my phone to hand whilst completing the build.

So I completed tuning the motors according to a post on cnczone forums, (also proving to be a valuable resource) I've just measured the total work area I have and its roughly 110mm x 330mm (which is a bit less than I would like) and have designed a fixture plate that's now all ready to be loaded into Mach 3 and cut out.

Then the fun begins and I can hopefully start churning out the items I designed in my spare time! I'm excited to see the first two items and see how closely they match one another, if all is well they should be pretty close to identical but I might be being optimistic!

In terms of next steps I have the following in mind:

Expand and strengthen worktop

Complete enclosure

Fit limit switches (already delivered and waiting to go)

Upgrade the 4core cable going from the drivers to the motors as its getting quite warm

And then I can think about my next project which is to build a slightly less rigid cnc router/mill but with a much larger work area

Hi AdyNI, Sorry to drag you back to this topic after a couple of years of absence.
I have a WM14 and am planning a CNC conversion.
I saw that you used 12mm lead screws and that you had to heavily modify the nut. I am wondering if you think, with hindsight, that you might have managed to use 14 or even 16mm leads screws? or any of the axis?

Also, how is it going - are you happy with the conversion?

Thanks for your help, in anticipation
