    Ben,
    I found some thin gauge wire that fitted through the vias on the tinyg board, and soldered them on. Step out was from those, as was direction. I was using the 2-phase drivers myself, no experience with the 5 – good luck!

    Very happy to hear it! I tried pulling the github page, and installing the javafx/java7 bits as indicated but stalled because of some errors.

    My understanding was that I should open the nbproject within netbeans IDE then compile and run from there.

    I get an error in ‘Main.java’ on line 65: import jfxtras.labs.scene.control.BeanPathAdapter;

    and in ‘ResponseParser.java’ on line 13: import jfxtras.labs.dialogs.DialogFX;

    Tried searching for jfextras, but I couldn’t figure out how to install that as a plugin for the IDE (compile using gladew? eh?); stalled at that…any advice appreciated.

    I’ve tried installing on a windows 7 32bit machine from, the linked alpha release marked ‘tgFX_windows_1_0_2’. If I start that up and connect tinyg, it appears as COM9, but when I click connect the status window at the bottom gives me the following:

    [!] Failed to find a field called [“sr”] at [“sr”] while resolving [“sr”] in [{“r”:{“sr”:{“line”:0,”momo”:4,”posa”:0.000,”posx”:0.000,”posy”:0.000,”posz”:0.000,”stat”:1,”vel”:0.000}}}].Line Was: {“r”:{“sr”:{“line”:0,”posx”:0.000,”posy”:0.000,”posz”:0.000,”posa”:0.000,”vel”:0.000,”momo”:4,”stat”:1}}}

     

    at which point I’m out of things to try.  Hope that’s some use to you; looking forward to the mac release.

    best

    Ah, lovely! Much appreciated.

    In case you can cast any light…I’ve replaced the regulator and checked the ftdi chip by desoldering & placing onto a sanguinololu board, from which it showed up in /dev just fine, then returning it to the tinyg.  The vreg is at about .28v-.33v at the 3.3v pins – any idea what might cause that?

    all the best

    Aye, well, it would be a bit above and beyond the call of duty to support boards being messed with in this way, just a spot of moral support here and there is all I’d hope for.  As it is, I’ve blown the regulator U2 and am currently waiting for a replacement whilst hoping that it was only that that blew. Looking forward to more tinyg in use…

    best,

    Amazing what a night’s sleep can do.  I had another crack at this this morning, using a sn54act245 ‘octal bus transceiver’ chip stolen from the parallel port breakout board. This is performing the level conversion and keeping up with the step rate, so I’ve now got the tinyg motion control working with external stepper drivers – my ideal situation!

    Next challenge is getting the spindle control to talk to a Huanyang VFD…

    all the best,

    Andy
