Wow, I can’t believe how easy that was. After hacking the transmitter yesterday without testing to make sure it worked first I thought I’d been a little bit silly. Today the motor controller arrived from France and I plugged it in, had to change one setting, and tada, working perfectly! That just never happens! I’m so happy!
Printers are still flat-out with other projects though so haven’t been able to find time to print out the rest of the sprocket mounts and wheel spacers. Some split-links also arrived today so at least I can get on with correcting the slack in the chains and see if I can do something to align the sprockets more consistently.
