so ..... again :set R12 to minimumleave R35 as isif setting R25 to max can't bring you from negative offset -to 0 offset , then :turn back R25 to zero , increase value of R26 for max 220R ( from 390 to ,say, 610-620 (whatever you have in drawer) ) ;turn R25 up , to have 0 offsetset both Iq and offset - fiddling iteratively with R12 and R25Tea - these are simple thingsif you can't do it easily on Sunday afternoon - leave it for tomorrow
