What makes you think the MT3 is at fault? The biggest issue I've ever experienced with the MT3 is collets locking in due to the self-locking taper effect.Don't see how changing to R8 will help - can...

Hi Folks,

I've just started using my 0704 in anger and it's made some nice parts (so far managing to hold +/- 0.05mm with no major problems. I've made a few entertaining mistakes with EMC2 - X/Y...

No we are fairly aware that without international trade in both directions our economy would fall apart. We couldn't come within twice the price of these and we have sod all manufacturing left. We...

Half the price and, if careful, perfectly good quality. It's a common misconception that it's all junk, because largely the same componentry is used in "quality" western products too. I've bought...

I've just bought a 110st with driver. 1.5kw/3000. I've only run it in the box and not in a machine yet but the motor seems very high quality, the driver is lower quality in feel but functions...

Oh that looks like a lovely solution, might look at copying that! I believe the spindle is only capable of ~4krpm in stock form but maybe more for short periods?

After cooking the brush springs on my stock motor, then blowing the control board I decided to just stop faffing and buy a new motor and controller. Ended up with a 110st-5030 ac servo motor and...

Dunno about Mach3 but you may be able to get it working with Linuxcnc if not. I suspect you will though, Mach is pretty flexible from what I see. Good luck on the build!

Has anyone got a cnc4you hg08 and a cnc4pc c6 to talk to each other? I'm seeing a variable frequency input to the c6 but it's apparently not listening. It will switch relays but the frequency control...

Well that was an odd evening, measured the motor resistance and got 104KOhms, assumed I'd blown either the motor or lost the brushes, Span the spindle a few times - nothing. Turned on the controller...

Mine only seems to have one fuse on the rear and that's fine, can't seem to see any more fusible items on the internal boards so I'm guessing it's either a motor or a solid state part fault :(...

So while making brackets to support my home and limit switches I forgot I'd started the machine in the config I was using to test the homing. I was manually feeding to take the corner off a bracket...

This is interesting to me as i stuck my meter on my speed control pot (ama25lv) which looks to be remotely similar and the pot has a full live (220v) across it.

It was going to be a slide-in rotary (I will only have 5 or 6 tool holders, I'm not looking at mega production work and don't care if the process is 2 seconds or 20 - I'm more bothered about it being...

Hi Folks,

Looking to build myself an ATC for my TTS style setup but I'm curious as to the dynamics of the tool change. Could anyone enlighten me?

It looks to me as though as the tool holder is...

Nah, even simpler - they're just threaded caps:

Hmmm FS wizard suggests 378mm/min with a 5mm cutter in 6061 (similar IIRC) which seems much more sane.

I'm not sure exactly how they do it, but I think I prefer a smarter way of doing it:
243380

Why make your life more difficult than it has to be?

Isolation is a tricky subject. Isolating the machine from the stand will reduce noise and vibration in the stand but could INCREASE vibration in the machine (and at some frequencies could reduce it...

Hi all,

I've converted a G0704 clone (AMA25LV) to CNC using some 4nm steppers, chinese ballscrews, homemade bearing supports and nut adapters and a BOB/linuxcnc. It's all working pretty well - I...

Lol I should never have started this thread, I still have conflicting opinions and no deal breakers!

Aye this is a hobby size mill, not professional (albeit at the larger end of the scale) but I am on my way to a cnc conversion and don't want my tooling to become a pain further down the road. Plenty...

Very much a European thing I think!

Oh that's interesting, I would have thought the taper insertion depth was more variable than that. You learn something new every day!

Pretty reasonable selection of sizes available in mt3?
http://www.arceurotrade.co.uk/Catalogue/Collets/Morse-Taper-Collets/Morse-Taper-Collets---METRIC including 8, unless I'm missing a point?...

Is that purely because the bits bottom out in the collet? Does wear not affect this and need calibrating?

Note taken, thanks! I will see how I get on, of its a problem I may consider a change. I have a self ejecting drawbar on the mill so I'm hoping I only have to do minimal beating to remove them!

...

Don't R8 use drawbars too? Making it a moot point?

And unless you can find a replacement spindle for your machine, there's absolutely no point using an mt3>er type converter as all of the issues...

Don't have much choice, I have what I have but I've never had (and my father has never had) an mt3 come loose with the drawbar done up reasonably?

That's not really helpful unless you explain why. It's very common, cheap and there's loads of mill compatible tools sold in mt3 and other than slow tool changes I can't see a reason against it.
