Re: [Emc-users] usb hi devices

I've been considering one of the flexible keyboards when my current one gives up the ghost.  They're not great for general typing but seem like they'd work fine for a machine control. The ones I've looked at are silicone rubber so they should stand up to coolants.

Have you considered rack and pinion for your machine. CNCrouterparts has a very affordable solution: http://www.cncrouterparts.com/rack-and-pinion-drive-nema-34-p-80.htmlI've not used them but they have gotten good reviews from users at CNCzone and I've been happy with other components of

Wow! That is really cool, Ralph! I would love to hear more details about your project. I have a bunch of questions like: what sort of resolution can you achieve, how much force does it  produce, etc.   +++ We are like

Re: [Emc-users] Using AMC analog amplifiers

Thanks for posting the AMC manual Eric. That's the most concise explanation I've yet seen on servo drives and their  modes of operation. Perhaps it would be a good candidate for the wiki?   +++ We are like tenant

Re: [Emc-users] Intel DN2800MT - possible new LinuxCNC star?

Re: [Emc-users] AC Servo Motor

It looks like 3 hall sensors for commutation on the inside and a magnetic encoder chip on the outside if I'm seeing correctly. The chip in the middle of the board is likely the encoder chip and the wheel below it a multipole magnet ring. I'd bet the datasheet for that chip would unlock the

Re: [Emc-users] hal 'net' command puzzler

Even the cheapie calipers have a serial port like the $16 one I got from Harbor Freight a few weeks ago. The manual doesn't even mention it but you can pop off a little cover opposite the battery compartment and there it is. There are a number of websites that document the protocol that is

That is a great writeup, Scott! It gave me a very solid understanding of what's involved in a complete servo system. Perhaps you could add it to the wiki?   +++ We are like tenant farmers chopping down the fence around
