Re: [Emc-users] Wireless card problems
snip Yabut... How well do those routers play with FIOS? You must retain the router that Verizon gave you as the CE (Customer Edge) device, otherwise you can't stream on demand video and the like. However, you can disable its wireless port and install a WRT54G (about half the cost of an RPi on eBay) with OpenWRT as your AP. You probably want to configure the WRT with a static IP address. Then, running it in AP mode, you simply connect one of its LAN ports via ethernet to the CE router. -K- Mark -- LIMITED TIME SALE - Full Year of Microsoft Training For Just $49.99! 1,500+ hours of tutorials including VisualStudio 2012, Windows 8, SharePoint 2013, SQL 2012, MVC 4, more.

I think that you would have to map the rotary axis position to one of the X Y or Z axis commands. What is the application? I can think of only one reason to synch the spindle to a rotary (gear hobbing) and that is more readily done in other ways. Yes, my client wants to hob worm gears. Now I need to check capability writing G33 together with A.

Re: [Emc-users] I'm going to build something small, need a cheap stepper driver.

Got the motors off, going to put the drawer slides on the yard sale tomorrow. Any reccomends on a really inexpensive way to drive these 6 wire motors? I am *very* happy with my TinyG: https://www.synthetos.com/what-is-tinyg-and-why/ Currently using it to drive a Sherline lathe. I am using 8-wire steppers (Applied Motion HT23-597D) wired as bi-polar parallel (4-wire). I have a bunch of 40/40 T-slot extrusion ($2.49 foot at a surplus company) with connectors that fit into the ends *and* inside corner brackets so it'll make a very rigid frame. I am thinking about a 3D printer, but I'll want the thing built very rigid. I recently saw a Solidoodle 3 in action. Not much impressed! The build platform is only supported on one side and I could see it wiggle, which appeared to harmonically combine with the motor motion to produce a visible waviness to the edges of every layer. The next step up from the TinyG is something like the machinekit that Charles Steinkuehler has built: http://www.youtube.com/watch?v=AK_OYoNOBDQ http://bb-lcnc.blogspot.com/p/machinekit_16.html This provides you with high power FETs to control heaters, etc. but is about double the cost (when you factor in the BBB) and needs two power supplies (assuming you want to drive you motors with something 12V). -K- -- How ServiceNow helps IT people transform IT departments: 1.

[Emc-users] MachineKit wired network disconnected
[cross posted to the BeagleBone Google Group] Greetings, I am a BBB newbie and trying to set it up as linuxcnc per: http://bb-lcnc.blogspot.com/p/machinekit_16.html. Base distro is Debian Wheezy. My host console is ubuntu 12.04 LTS running as a VM in OS X. After booting the BBB from the SD card, connecting it to the VM, and running ifconfig eth1 192.168.7.1 I am able to ping 192.168.7.2 and ssh as either the root or linux user. However, shortly thereafter ubuntu displays Wired network Disconnected, the ssh session is frozen, and eth1 no longer shows inet addr:192.168.7.2. The message keeps appearing periodically. I have added udev rules via mkudevrule.sh but no joy. Any ideas? This behavior does not occur when I boot the default image from eMMC (and I do not have to manually add 192.168.7.1 either).
