I am just setting up DCC++EX on my 2 year build layout which after building a shed to fit it in I am know moving on to running, I built a DCC++EX Base Station using a Mega and Arduino Motor shield No Wifi shield till all works, but I have an issue with a Lais Decoder I have, after trying to set up in JMRI I may have messed the decoder up as it worked fine on a Hornby Select but motor wont run when added to roster with address 3 on the program track ( I am using a Lais Decoder Tester with decoder connected ) and use throttle, if I put on Main track motor runs at full speed and throttle has no effect, I tried a CV 8 setting to 4 and when I check all CV's they are all correct to Lais sheet except when I select CV33 I get a No responce from Decoder and unless I reset Track power OFF/ON I cant read any other CV's..
If anyone can help I would be most grateful, I have a Class 55 loco with same Decoder but im loathed to put on this setup until I find what ive done wrong..
