At roughly double the price ($7000 vs $3500) and size of the OtherMill - I suspect the small Tormach is a -very- good value for serious CNC.

On the other hand... Kadee has a Haas CNC up in Oregon that is somewhat smaller than my 2-car garage!!!!

That one has fast enough spindle speed to cut metal.

I don't know what SLP is; what do you think of Roland SRM-20. It has somewhat larger working area but still quite compact: https://www.rolanddga.com/products/3d/s ... ifications. Sadly it probably can't be used for cutting metal, so a lot of people wouldn't take it seriously but I'm mainly interested in making low volume resin molds. I wonder what the runout is (apparently unpublished)


Actually you don't want high spindle speeds. High spindle speeds are used with high fate rates for fast milling.

From looking at the specs it's close in size to my Sherline CNC Mill but much fancier looking. From what I read and what the video shows this machine was specifically design for the materials it cuts. It's a machine designed for prototyping ideas. This spec, Mechanical Resolution 0.0000393 inches/step, 0.000998594 mm/step, tells me the spindle runout is probably very high precision. Something I wouldn't worry about in making resin molds.

If I had the bucks I would go for this machine.

I like the idea of having high precision resolution so it's not a constraint if modelling the smallest details such as hinges and door handles. OK I emailed Tormach with a question. It would be nice to be able to actually work with metal.

Woah. Those lucky ducks.

There's a saying in the machine world, especially about a lathe, You can turn small stuff on a big lathe, but you can't turn big stuff on a small lathe.

At times I wish I would have purchased a bigger CNC mill. There are multi gauge projects that sure could use a bigger working envelope.
