Re: [Emc-users] off topic opinions

All these all in one machines have the problem of unproductive times. I own a small table top machine (google for Hommel UWG2) which is capable of 1/100 mm precision easiliy, maybe better, but it takes hours (literally!) to convert it from turning to milling, tapping etc. and vice versa, so I d

Re: [Emc-users] LinuxCNC would be very nice on the UDOO board.

The Beagle Bones are so cheap, that we shouldn't be worrying about how many pins we can drive. Just connect a few together using etherCAT or real time ethernet, or whatever the thing supported by the hardware is called. As far as I'm concerned, the problem of no parallel port has been solved

Re: [Emc-users] "Black BeagleBoard: available at $45" (was LinuxCNC would be very nice on the UDOO board.)

You might look at changing your distribution if a shutdown on the pi is taking that long. I'm using archlinux in a mobile application and it will fsck and unmount the filesystems, and complete the halt, in ~2-3 seconds. On Wed, Apr 24, 2013 at 12:20 PM, Ralph Stirling < ralph.stirl...@wallawalla

I think when I pick up a couple of these this summer, I will try incorporating an ultracapacitor-based "UPS" that can hold up power for the ten seconds required for a true shutdown, along with powerfail detection to initiate the shutdown. The Raspberry Pi took well over 30 seconds for a shutdown,

Re: [Emc-users] off topic opinions

I think the distance from the milling head to the lathe chuck is too short. You're going to run into trouble the first time you try to machine a part of any size, and taking the lathe chuck off is an option but it's a pain in the a$$. Then I looked at the Midas http://www.smithy.com/midas which

I looked into Smithy machines a couple of years ago, and decided that there was not enough rigidity in the machine for what I wanted to do. If you want to do very light, hobby work, the Smithy might be good enough. I mentor a high school robotics team, so I wanted machines big & heavy enough to st
