Hi all

I decided to cnc my warco wm14 mill and went from no cnc knowledge to having a pretty good understanding, all from this forum and your cnc builds!

This is still in progress and I'm just waiting for arrival of a 12 mm ball screw for the x axis

Dual boot old Mac with Windows xp - no parallel port so I needed to buy a uc100

Recycled an old speaker panel for electronics, just using an mdf box until I buy a computer enclosure.

Started milling the mounts and I know this will need to be modified before I'm done!

Added a cheap and cheerful enclosure to save me spending too long collecting swarf:

And I got myself a portable vacuum from gumtree to help [emoji5]

Looks like a great project. Keep us posted on your progress. Lot's of knowledge on this forum if you get in a bind and need help. Good luck with your build!

Thanks Tom, I'll add more details in the next few posts.

Add the moment the only wait is on delivery of bearing blocks and ball screw.

I ordered a 16mm screw for the x axis but there's no way enough clearance for it so waiting on a 12mm.

I went with 425oz/in motors, I'm a bit worried the z axis will struggle but I haven't sat down and done any research to find out how powerful these motors need to be.

Looks great so far! Im also in the UK, would you mind posting where you sourced your "bits" from...Im thinking of doing a Warco WM18 conversion in the near future? Many thanks, and keep up the good work.

Hi Matabele

Did you mean all of the mounting plates and motor mounts? Or the other bits and pieces (ball screws, couplings, stepper motors etc)?

I've now reached the point where I have to mount my ballnut to the saddle and not sure of the best way to do this! I've seen lots of examples of people grinding the saddle away to make clearance for the ballnut and am thinking of going his way myself, otherwise the ballnut will have to be mounted on the left hand side of the saddle, I may have enough room for this!

Sorry, my question was a bit vague. I was interested in where you sourced your ball screws, couplings, stepper motors, electronics etc? Thanks!

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:

4b11fcf5a5ee96c38d04f1171fa69fce.jpg

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 [emoji19] 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

99d72795b46a71ac670435f3b5814468.jpg

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 [emoji48]

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 [emoji849]

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! [emoji48] 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 [emoji48]
