I started off with a £6 router from the car boot sale. Didn't last long ... then I was persuaded to get the water cooled spindle. Couldn't really afford it at the time (Mum and Dad took quite a bit of persuading!) but I'm glad I didn't get the Kress as after having read more about both of them the water cooled spindle is clearly worth the extra.
Okay good question.


Super will cost me $181.00 (£118 as of this posting)plus incoming VAT (I get that back as a business) plus the processing fee of max £10 by the courier. Which as I said in the post you quote has very good performance record in not only speed control but in maintaining torque via maintaining rpm. Then setting it up with the System 4 break out board and Mach3 (about two days worth of work including testing)

1.5KW water cooled spindle ~£140 delivered +/- £15. Then a quality VFD 1.5KW VFD that I can get serviced?warranty in the UK will cost between £120 and £180 depending on type and a few other options. Add on to that a coolant pump and Radiator with fans and thermometer for fan control (£150 max). Plus the aluminium for the mounting brackets to be cut as well.

That is why the wait and going with the SuperPID and double brackets on the Kress until I build up enough cash reserves from product sales to buy the materials to go the liquid cooled route.

It is a matter of economics and what I can do at this time to improve control and repeatability of the work I am doing. The SuperPID will be a massive step up in control and safety.

I am looking at the 1.5Kw as that is 2HP and more then enough power for the cutting that I will be doing for a good while. I might at the time of buying the water cooled decide to upgrade to a 2.2KW unit, but will have to see at that point.

I hope that explains my reasoning and in a clear fashion. My only request is that this is taken as ONLY simple explanation and nothing more.

On the machine build side of things the testing of the break out board went well after setting up Mach and doing a few other items. Also found a Parallel port card that has two ports on one card and need to find out if that would cause a problem with information out bound or not. As it looks like a rather nice option for my PCI slot challenged mother board (when I start pulling the rest together for the fourth axis).

Hope every one is doing well and having fun making chips.
