Thanks for the info . it would be prudent to refit the sem dc motor and try it for a while . the original sprint 1200 board may be toast if i still have it . i had a quick look around the net . does anyone know if this is suitable ? as dc motor control is above my paygrade

if not can anyone recommend a suitable control which is not £1000 .


any help greatly appreciated
