Re: Vacuum Table for Shapeoko 2

You'll need a lot of vac to hold pieces down. I use a vac table on my 5x12 industrial router at work with a massive 480v dual impellar vac pump and that smallest piece it can hold and cut is about 1.5'x1.5'.

EBay has all kinds of endmilla that you can use. I personally order from JTS machinery, good prices and good selection. You can get a nice 2 flute coated endmill that'll be deep enough for under $12 iirc. They have an eBay store for quick ordering.

Re: Cutter flute lenght for Aluminum

I'm going to attempt to cut new spindle mounts from 1/2 inch aluminum. I found a nice end mill for aluminum on ebay a while back, but the flutes are only 3/8 long. I'm doing a test to measure my runout in 1/4" and it's working great so far. http://www.ebay.com/itm/380824507246?ssPageName=STRK:MEWNX...

Re: thread milling with shapeoko2?

I favor the single point thread mill. That way one tool will work for multiple threads as opposed to needing a different tool for each thread pitch.

Re: thread milling with shapeoko2?

The big thing you have to worry about is backlash. Odds are you'll at least have to trace the hole with the proper tap upon completion.

Re: I need help with Mach3

id recommend stepping up to a dial gauge as opposed to a ruler, much more accurate. Mach 3 has a step per in calculator for use with a dial gauge.

Re: Pictures of finished machines

Ill post some of mine soon. Almost finished with the tool plate I made for it. 3/8 6061t6 plate with m6 threaded holes to replace the stock mdf board. Gives the machine some weight and more accurate fixturing.

Re: Gecko G540 Upgrade

Youll either need a male to male cable or a gender changer for a standard cable. Avoid cheap cables as they can be more hassle than the money saved.
