Hey everyone. I returned to the hobby last year, building an outdoor oo loop due to lack of indoor space and my enjoymejt of running full length trains.. (so far single loop with a 3 road fiddle yard, yet to add a couple of sidings) The track is all peco code 100, soldered links between track sections, and feed wires to each rail running all around with 'droppers'. The points are all modifed with feeds to the point blades for outdoor use. It runs fine on DC. Obviously, although level as possible, its not perfect due to being outside and on roofing felt covered decking boards.
This year I thought Id give DCC a go. I aquired an arduino based controller to use through phone app 'locomotive wifi 3' app as lazing in the garden controlling trains via phone or tablet seemed fun. So far ive fitted zimo mx638 decoders to 3 Bachmann class 37's.
Problems are constant stalling at random places, not just the 3 points the locos cross. sometimes they'll stop, take off in reverse, then resume. sometimes they'll speed up randomly.
Track is clean despite being outside. I tried the locos after much track cleaning with peco rubber and alchohol as well as wheels and pick ups. The lights remain on when the locos stall.
Tried some cv settings such as disabling dc control.
Phone is close to the wifi controller so no signal problems.
Power to track is through a clean 2 pin plug, the sort for mowers etc.
At this point I feel like just keeping DC, perhaps playing around with dcc with another controller at a later date. Perhaps these controllers that use a phone or tablet app are just not that great? Perhaps its the slight undulations and unlevel track that cant be helped with running outdoors? maybe its loco/ decoder combo? Any help would be appreciated, thanks
