Thanks everyone for your tips. Using pg 16 of the manual to reprogram the Command reverse unit to restore features fixed the problem with going full speed all of the time and restored the lights. TMCC commands seem to work now.
The ability to change speeds is still hard to control and slow down quickly to avoid a crash is difficult so I will try the stall settings tonight.
It doesn’t move at all in conventional mode but I’m ok if I can improve the TMCC performance.
Thanks again.
