Hey are we talking about the spindle or Motor tuning here.? They should have no affect on each other.
Jog should not affect the spindle in anyway what so ever. Similiar in MDI only commands that should affect Spindle is M3/M4/M5 and S (speed).
Asked before can you post picks or show drawing of exactly how you connected because something is very wrong.
Also Either show how you have Mach3 setup or Zip up your XML file so can take look.

The Bob needs a 5v connection from the PC. There are terminals to take the PC side of the power and a USB connector also. If you do not connect up 5v from the PC the opto couplers will not work properly.
I can't see that connection on your photos.
Here's a link to the Bob manual in my dropbox https://www.dropbox.com/s/v1fha65o2p...rd-EN.pdf?dl=0 Just in case you haven't got the document.
Cheers !

I had similar problems/ still have/ due to bad earth link between my equipment, whatever that means. A direct wire that connects the VFD drive Earth to the PSU Earth that powers the BOB solved problem. Have seen reports that same wire to PC Earth/PC body/ could cure the problem also.
Switch spindle on, set to 16000rpm and do try that.
