TOS-KURIM CNC Upgrade

Steppers, on the other hand, are much simpler to set up with hardly any learning curve involved and quite a bit cheaper. They can be run on a lower level of controller.
The downside is they are limited to roughly 1200 to 1500Rpm so feeds are lower. Resolution is lower compared to servo's but still more than enough for milling at this level.

Choosing the correct drives and size is critical with large steppers because you don't have lots of spare power as you do with servos. So if you take this route then look for 220V Mains powered Drives rather than lower AC/DC drives running say 80Vac or 100Vdc.

I've used these many times and they are a great set up with lots of power and provide reasonable torque even at high feeds. More than enough for your machine.

Hope this helps, got any questions just ask.

Crikey these are hard to come by in the UK! plenty of 80V and 100V ones around but no luck on any mains powered ones!

is that link you posted somewhere you've bought stuff from before?

Yes I buy from them all the time. Don't worry about buying from China as they are trustworthy and well proven with many users in UK.

Also if you buy them thru the Aliexpress link I gave you then your protected by Aliexpress guarantee, they basically don't pay the seller until you have received them and say you are happy. They still charge you upfront but do not pass the money on until you are happy.

Edit: You will get charged VAT and Admin fee of around £15-20 on top of that price when they enter this country. You don't get charged Import duty.
