Still Pluggin away here, Have sensors lighting up on the track plan now, still seem to have a weird irritating problem on the two points servo's. IF I select one of them with the wi-fi throttle I can then switch it with the diagram in JMRI but not the second one. IF I then select the second one I can switch that one but not the first one.Must be finger trouble somewhere. Mounting the sensors in the track today and will then try the routing system, possibly tomorrow. Shake a leg Paul need some moral support here . (Are you using JMRI ?).
