Hi.
I’m using the TinyG2_Due_rob_usbtest.bin binary from http://synthetos.github.io/g2/ on a Due with a stepper shield using A4988 stepstick clones to drive a large laser cutter mechanism I’ve designed. It works well with a minor problem revolving around homing switches.
Everything seems to be wired and configured correctly, and indeed it drives the motors perfectly, so I can drop a gcode file in and it will execute it quite happily. Issuing a G28 command will make it home to it’s 0,0 origin correctly as well. But if I give the G28.2 X0 command, for example, I get an error:
“*** WARNING *** Homing error: X axis settings misconfigured
The same error occurs for any axis or set of axes. I have gone over every scrap of documentation I can find with no result, I can’t find any setting I have missed. Either I’m still missing something (entirely possible), or there is a real problem, which as far as I can see must be a bug of some sort.
I notice that the $ST command to set switch type as NC or NO gives an unrecognised command error, as does $BSN and $BSN, although all the other switch commands seem to work. Is this binary broken in some subtle manner?
Any help on resolving this would be much appreciated.
My complete configuration is as follows (note that only the X and Y axes are in use):

I don’t have any useful G2 experience yet so can’t really help, but suggest you post what Interface OS (Win, Mac, Linux) and tool (Coolterm, putty, etc) you are using to interface your G2s as suggested next steps may be different for each environment.
Also, GREAT idea to make your configuration info available as pca did, but I suggest to post it to a dropbox(or similar) .txt file and post a link to that file.
As you can see above, the WordPress Forum tool removes whitespace from the parameter listing, making it more difficult to scan for values.
Using the code tags option in WordPress is somewhat better, but the scroll bar is all the way at the bottom on the long listings.
Here is an example (for tinyG ver 1) :When reading forum items, I frequently open the configs in a new browser tab (right click on the link) for easier analysis of the issue and configs with less scrolling of the screen..
Alas, you’ll have to wait for Alden or Rob to stop by for real help with the issue at hand.
Edit: Ha, Alden and I were typing at the same time.
