[Emc-users] AC servo driver, Recommendations/advice requested

I am looking for recommendations and/or advice for driving a Harmonic-drive-systems FHA-40C-100-E250 Actuator that I will be using as part of the 4th AXIS on my Mill. The motor appears to be about a 1KW unit with max RPM of 3000 and has an encoder that provides 2500 pulses per revolution.

[Emc-users] Documentation Clarification

Hello all, Was reading in the HAL documentation and I found an inconsistency. 2.2 Examining the HAL In the section under Show Pins the following text appears: "... hundreds of pins. But right now there are only nine pins. All eight of these pins are floating point, and carry

Hi, The centroid is a more extravagant version of what I have here: http://xylotex.netfirms.com/OSCommerce/catalog/product_info.php?cPath=27_id=114 which is $39.00 (no BBB included) A BB Black simply plugs on to the Xylotex BBX (upside down) and provides a standard parallel port type

Yes, of course this has been done before. I was pointing out that it is easy to DIY without a PCB. Easier than using flying jumpers Really it is just a way-oversized "cape" that is upside down laying on it's back On Fri, Mar 24, 2017 at 8:43 AM, andy pugh wrote: > On 24

Re: [Emc-users] Centroid is dabbling in the hobby market

Yes a Beagle Board and their mechanical mounting system is worth looking at and emulating. They made a larger PCB with pins that mate withe the BB and then turn the BB upside down and pushed it into their PCB.Kind of like treating the BB has a very large chip placed in a socket. I've

I wonder if they'll answer emails about it. I bought a Centroid control secondhand, they wouldn't even talk to me. No way I'd willingly hand them money. On Fri, Mar 24, 2017 at 3:26 AM, wrote: > People are excited about this. Still need a computer. (Mesa Ethernet >

Re: [Emc-users] More Renishaw questions

Switch on is not a problem for me since the MP7 has an inbuilt centrifugal power switch according to the docs -- spin the probe at 500 rpm for a few seconds to turn on and then spin it again to turn off. I would appreciate any information on your homebrew OMM that you're willing to share. Please

Oh - interesting... Didn't even notice that. It says it is a beaglebone green. Maybe it is running machinekit ;) sam On 3/24/2017 4:15 AM, andy pugh wrote: > On 24 March 2017 at 07:26, wrote: >> http://www.centroidcnc.com/centroid_diy/acorn_cnc_controller.html > It's
