Re: [Emc-users] CoreXY Kins and the BeagleBoneBlack with MachineKit
I actually did try that, but with no luck. I tried a couple other kinemtatic models. Gantrykins and delta, with similar results. The net Pin assignments are all the same as they are in the example K9 PRU config.

If your motors turn properly, but kinematics isn't doing it's thing, it sounds like it's time to post your configuration to the list. What sort of machine is this anyway?

Re: [Emc-users] CoreXY Kins and the BeagleBoneBlack with MachineKit
Here is my config. At this point its still the same config that Probotix supplys with the exception of changing to from trivkins to core_xy_kins. A CoreXY or Hbot machine works on the same principle, driving the X and Y axis from the same belt that is routed along the lengths of the axes. Its all explained here, http://corexy.com/theory.html. In this setup to move in say X both Motors will have to move together, in the same direction. If you are driving to a 45deg angle, one motor moves. So somehow I have to connect the xy motors to deal with this. I imagine it would work similarly to how a delta bot is configured. I just attached the config. If I need to post it in plain text just let me know.

Re: [Emc-users] CoreXY Kins and the BeagleBoneBlack with MachineKit
Thanks, that's pretty much what I thought the machine was like, but I wasn't sure. Can you also provide the actual kinematics file you're using? I'll compile it and see if I can and get it to work or fail with the same issues you're seeing. On 1/24/2014 2:09 PM, Joe Spanier wrote: Here is my config.

[Emc-users] CoreXY Kins and the BeagleBoneBlack with MachineKit
Hey Guys, Im working on building a 3D printer using a CoreXY kinematic setup and was wanting to use the BeagleBoneBlack and the PBX-BB Cape to control it and using the latest version of MachineKit that was released at the end of Dec. In my Google searching I've found support is slim, and most of the posts point me back to this http://www.linuxcnc.org/index.php/english/forum/38-general-linuxcnc-questions/26302-cnc-avec-systeme-h-bot-ou-corexy discussion on the community forum. When I try to follow Andy's instructions inputting the instructions to activate it I get the following: sudo comp --install core_xy_kins.c - sudo comp command not found sudo apt-get install linuxcnc-dev - linuxcnc-dev not found (I also found that google translate ruins code haha) So where I'm at now, is I cant seem to install linuxcnc-dev, and there is nothing in my sources for linuxcnc. I dont want to add anything and break MachineKit either. I haven't dove in super deep into how its built so Im not sure what all I can mess with.-- Thanks, Joe Spanier No Trees were harmed in the sending of this email, but a great number or electrons were terribly inconvenienced -- CenturyLink Cloud: The Leader in Enterprise Cloud Services.
