Re: [Emc-users] Semi OT: Chinese servo motors Yifeng branded

Thank you guys. I asked to the seller for manuals or any kind of documentation to start. Then may be I give it a try and purchase a little one to test it out and see how it works. I'll let you know whatever happens. 2017-06-01 4:50 GMT-03:00 theman whosoldtheworld : >

Re: [Emc-users] Simulations In Master?

Perhaps a spoke too soon about it all working. Linuxcnc started with my config using the new sim_parport but I'm running into a few bugs. I don't know if the problem is my config, or a bug in Master. The config is a 4 axis XYZW config, with only XYZW and joints 0,1,2,3 defined. (I really like

Re: [Emc-users] Simulations In Master?

I'm not sure that there are any. I'll have to check what does and doesn't show. I do know that the normal example configs with 1 port run fine in the VM (VirtualBox). - Original Message - From: "Sebastian Kuzminsky" To: "Enhanced Machine Controller (EMC)"

Re: [Emc-users] Simulations In Master?

Thanks Andy, I made a new component (sim_parport2) and that seemed to work. Perhaps someone should put a revised version of sim_parport in the main release. - Original Message - From: "andy pugh" To: "Enhanced Machine Controller (EMC)"

[Emc-users] Simulations In Master?

I was trying to convert one of my machine configs to test with Master. Testing in a VM. I've ran into a couple of snags though. The machine uses 3 parallel ports, two of them in X-mode, and one as Out. When I try to run the config I get: Error: could not insert module

Right now I design away from Ethernet within machine because with my computer and switches and it does not work perfect. Whatever the reason is I simply can't do anything about it. On Thu, 1 Jun 2017 10:32:27 -0700 Chris Albertson wrote: > Modern Ethernet does not

Re: [Emc-users] emc2 openProfibus

Modern Ethernet does not have a collision problem. It uses a switched topology. All of the cables are point to point. One end is on your device the other is on a switch. The switch has enough performance and bandwidth to drive all cables at full wire speed. The switch adds very little

Re: [Emc-users] emc2 openProfibus --> openPowerlink

Yes openPowerlink might be a really good choice. I implemented CANopen over UDP for configuration a few weeks ago and openPowerlink is adapted from CANopen. The SDO communication from CANopen work really well for configuration and I guess it should also work well for between machine

Re: [Emc-users] emc2 openProfibus

If Ethernet is "complex" then PowerLink is "very complex" as it is a few layers over top of Ethernet. Is there a list of requirements some place? What are the end points, processes that run on a CPU of some kind. I've been doing this kind of work for ages but you can't select anything without
