I've read alot, and learned alot, here on the forums, so when I finally pulled the trigger on a new system I decided that, I too, would document my experiences as a kind of pay-it-forward for the next guy. So.... Thanks everybody who posted before, and good luck to those still figuring it out.
Note, The events here started on 4/17/2016. If you're reading this much later, then keep in mind that information changes and products get updated.
I'll spare you the months long analysis. I decided to go with a Precision Plasma llc gantry kit. The systems look to be extremely high quality, within an affordable price range, and very very high reputation. In fact, I could not find any bad reviews. After more analysis, I decided to go with a 5x10 table, as it is the largest size of metal sheet which is reasonably available, and anything smaller would some day lead to me whining, "why didn't I just get it 2 feet longer?". I have also decided to go with the Hypertherm 85. Once again it is incredibly well supported and thought of, and (yet again) it is the largest reasonable size.
O.k., So which one? Precision Plasma's website showed 2 models, the Magnum and the 8020 HD. I am a machinist who can weld. I am not a welder. I was planning to go with the 8020 HD, as it is a more bolt together kit, and I never intend to route with it. Just a couple of days before I went to make a purchase, the site was updated to include The Speed Demon HD. The real difference is the LM76 rails. I was sold. I didn't like the idea of trying to fabricate rails from CRS, as I'm just too picky and worried I wouldn't like the result.
A few emails later, and I sent Ron at PPllc a money order. Hoping for parts soon. My parts and choices as follows:
Speed Demon HD 5x10 Gantry Kit 2995
PPllc Z-axis 650
Magnetic Break-away Mount 400
300 oz Z axis motor 50
Shipping 150
Grand total so far.............. 4245
I chose the more expensive PPllc Z-axis over the Velox unit as it uses a ballscrew vs an acme thread. Coupled with the 300 oz motor, this should let my Z feedrates really fly! Ought to make for some spectacular crashes too! Hence the Magnetic mount.
Random Note: If you opt for the 300oz motor (from PPllc), you will still be getting 4 motors in the CandCNC kit (when you order it from them later). Makes for a spare. Also the 300oz motor comes with 15 feet wire leads. The 5x10 needs 25 feet. I'll deal with that later.
