Re: Filament Stops Flowing

Well, a month later, I'm back.  I bought a board, been sitting on the desk for 3 weeks.  It uses different connectors than the SD board - JST vs JST XH.  So I bought a kit, hafta rewire the connectors.  Now comes the problem.  The  pin outs on the new board are labeled 1B 1A 2A 2B (in that order)with the common (square solder pad) under the 1B.  The SD has no labels, but the common lug is in position 4.  I have attached a couple of pics in the hopes that someone can identify the pin outs and/or wire colors.

Re: Filament Stops Flowing

As mentioned the square pad designates pin 1   on the board
