I just think the air cooled spindles are just easier all the way around. And I've run mine as much as 20 hours a day sometimes with no problems.
But ... on another note --- been considering a bigger machine and was leaning towards the Saturn II. But it is quite heavy and bulky the way it comes. Don't know how I'd get it in the basement. Soooooo I thought back on your discussions and CNCrouterparts came up. I can do the 4 x 4 Pro. Just have to put the frame together and hook the boxes up with the right wires. They have it now where you don't have to be a lectrical genius to get one of their's up and running. I would have to learn Mach 4, though.
More food for thought.
I’ve done a lot of research over the past five years, and haven’t heard a bad thing about cncrouterparts. I’ve talked to Cory on occasion, and they are very helpful and available.
You can also deviate from there design ,and request a different size.
In my case I want a 5x5 ,as there’s certain quality of B.B. that only comes in that size .
Dealing with CNCrouterparts would be the closest place possible for me shipping wise also .
I like the Saturn also, and with David’s input I suspect Nates addressed most of the issues .
Although the gantry can be removed, I can hardly imagine trying to get a 4x4 Saturn into a basement lol.
But a CNCrouterparts would be a cake walk .
As I mentioned, I would like to follow in David’s footsteps and build the electronics myself . I want a better understanding of the system,and I would like to have things laid out in a bigger enclosuse to make trouble shooting easier . I love working with electronics anyways, so that helps .
There’s a few good videos on assembly of the CNCrouterparts Pro version
