Thanks for the update. My apology for the late reply. Unfortunately I have been unable to replicate your jogging issue. I'm sure there is a solution, but without the ability to make it happen here, I am stumped at this time. We have had no other users reporting this issue to date, so I am wondering if I am missing something maybe unique in your setup. I will do more testing later today with your grbl settings installed on my working machine to see what I might find. Can you email me some pictures of your machine and its controls/wiring/etc? They might be of some help in my testing. Thank you.
EDIT: Joe, please forget my picture request. I saw enough I think by watching your video again. So far when testing with your settings installed on my test machine, the only thing I find so far is your Z axis works backwards from mine. But that is not an issue, simply a minor difference in settings. I will post more later.
