I have some spare parts that might potentially be able to be used to make a light duty 4th axis. I have an R8 spindle shaft and could fabricate a housing and probably find an adapter for a 3-4"...

Sorry, being lazy but I didn’t want to read through all 29 pages of this thread. Is there a website where this is sold?
Thanks!

I know this is an old thread but wondering how you were able to adjust out all the backlash? And, the method you used, is it applicable to all/most rotary tables?

Thanks for posting your procedure. I’ll have to give this a try soon.

Has anyone given any thought to using a TesaStar-MP touch probe? They’re all over eBay and supposedly are compatible with the Renishaw TP20 and also made in the UK. I’d like to try what you guys...

That’s what I was thinking. Bummer and they sure want enough for it. How long ago did you order your enclosure?

I thought about making my own but didn’t want to invest the time. I made my current...

Anyone have a 440 with an enclosure? Thinking about ordering a 440 but after watching vids on YouTube, I’m thinking the enclosure leaks at the bottom of the doors. I emailed Tormach and they said...

I don’t know what that is...got a link?

I’m trying to figure out a way to put some doors on my mini mill “enclosure.” It’s basically an open top, 3 sided box around the mill and is only just a little wider than the machine. Doors that...

Very cool...I like it!

I'm looking for wire management ideas for the x-axis motor wiring on a mini mill. Drag chain is obviously not an option because of motion in 2 axis. I've searched around and haven't found much for...

Thanks, Kenny, for the encouraging words. I know Clearpath motors on a mini mill is like putting lipstick on a pig. But it's what I wanted to do, just to be able to see what they're all about. Due to...

Okay, so now that I'm thoroughly discouraged, please tell me what mill in a similar size would be a good choice. I'm assuming there is no such thing, so rephrase the question to what is the smallest...

Thanks Ray, understood. But what if I one day modify the mini mill to use linear rails or something like that (very possible)...will it then be advantageous to have the high res motors?

I just...

Well, for the time being, let's forget this is for an X2. You never know what I may end up doing with it.

So Jumper says smoothness will be improved. That makes sense to me. I would think this...

Okay, there has to be some reason why a higher count servo is advantageous. I'm using an Centroid Acorn board for this setup. Centroid seems like a pretty serious industrial type company and they...

Thanks for the reply, guys. That's about what I figured but then there are those guys with the high res motors, I thought maybe I was overlooking something.

I hear what you're saying, Ray, but...

Hi again Jim,
Well, I went ahead and ordered the Clearpath motors...went with the ones that produce about 600 oz. of peak torque. Anyway, I went with the "regular" version with 800 steps/rev. I'm...

Thanks, Jim. Would you have any recommendation for a BOB and motion controller? I have an ESS and a cheap Chinese BOB for the mini lathe and that works fine. Wouldn't mind trying something else, if...

Hi Jim,
Thanks for the reply. I believe the mini mill conversions usually use a stepper rated around 350-400 oz/in. I think this is the stall or holding torque rating. When you say to use the same...

I'm on the fence here and am hoping for some advice. I'm very new to CNC and recently finished a Sieg mini lathe conversion using an inexpensive Longs Motor package purchased off ebay. It uses...

That's a pretty amazing transformation! Looking forward to seeing it all finished up. Curious...what Clearpath motors are you using?

If the ballscrew were a bit longer and the motor mount were a bit deeper, perhaps there would be options. The way it's designed, the coupling is, for the most part, within the bored hole in the motor...

Just a very small job...

I need a few ~1" OD acetal Oldham coupling disks made up. This is the stock part here:
OD16/25-AT, Oldham Coupling Disk, Acetal | Ruland

I need the disk modified to...

Thanks, yes, the coupling is sort of holding up the motor end of the screw, but I think because it's such a small mill and relatively short screw, the ballnut is also doing it's share supporting it. ...

Well, a quick initial test of the Oldham couplings is promising. The ballscrew seems to be supported enough so that the coupling stays engaged enough and, so far, it seems to be quite usable. The...

This is what I ordered:

Just to clarify, the Oldham couplings I ordered are the kind with the delrin coupler thing...not exactly sure what it's called. These are not the spider type of coupling. With the spider type, the...

I have no idea why there's no bearing on the motor side. I honestly didn't study their website too much prior to purchase as there are not very many options for ready made kits. The machining looks...

Unfortunately, I don't have the resources to modify the CNC Fusion kit at this time. I actually don't think a bearing can be added without sourcing a longer ballscrew or sacrificing x-axis travel.
