Too true

looking at this on alixpress when I build another one (I want 8*4 capability) I think I should just use these all round at this sort of price unless I'm particularly lucky with the next machine that comes in.

I was thinking the best thing to do with the supported rail is to use it until it becomes an issue then keep the rail and bearings for a table saw slide to make cutting 8*4 a joy.

Although I want at least one axis to have 3m rails.

So going to cost a £1000 by the time the import tax man has his fingers in the tills lol.1

Exactly these ones i had problem with. I had just one sample though. Check Robodig ones, they seem better to me

So I wish to upgrade from my Kress motor and I'm wondering if the spindle that started this thread is the way to go?

Advice please.

That's the one if your machine can carry it. https://www.ebay.co.uk/itm/2-2KW-WAT...c=1&rmvSB=true

OK, rightly or wrongly I've just ordered one of these spindles from Germany.

So now I need to:

• Source a bracket - recommendations please -?
• Learn how to configure and operate the spindle - I'm sure there's an article or 2 on this site somewhere - ?
• Absorb recommendations etc from folks who have such a device - ?

Hoping folks can point me in the right direction.

That's the one I have

Something like this is good
https://www.ebay.co.uk/itm/80-100mm-...QXW0C2j_rVrnVg

Mine took about 10 working days to arrive.

If you wire it to the BOB to control speed and turn on/off then there's not a lot to setup on the VFD I haven't done this yet so control the speed from the VFD but it makes more sense to wire it to the BOB.

The manual is confusing but there's a great thread on cnczone about how to use the vfd and all the info you need is in the manual just in Chinglish.

Thanks - bracket ordered from ebay (There's many sources of 80mm bracket on ebay I now realise)

This is the in-forum set-up article I was originally looking for.

Just need the spindle to arrive now.

Now onto appropriate collet sets ...

Could someone recommend a cost-effective ER20 collect set appropriate for a Chinese spindle.

Had a look on the Internet but I'm confused about the vast range in prices and therefore don't know how to choose an appropriate set. In shorty, I don't know how to grade/judge ER collects.

Thanks.

You can also fit a pot on the front panel to control the speed http://www.mycncuk.com/threads/7388-...se-Spindle-VFD

I can't recommand any specific seller but eBay is full of ER20.

BTW, I bought my spindle from the same seller as you did. After about two years it is still working well. Just make sure you connect the earth because the spindle is not earthed. Mine is just a 1.5kW air cooled, but I am still happy with it.
