Hi very new here needing snackshop 103 coinco help

[Sikstar]

Hey i got a snackshop 103 about 2 weeks ago. I have programmed all my stuff in the machine about 5 bucks [ its all art not snacks.] Well last night i brought it to the first exhibition ill do with it... someone tried to purchase somwthing and it only would accept 1$ and only 2 of them... i tried changing the number dial. Thought i had changed to accept all the bills but even trying it after setting it.

It seems to only accept 2 dollars. Help. The coinco machine is a ba30l2sa. [Which is writen on top of the actual label..underneath that is ba30b im not sure why its like that as i got the machine for free. Any help would be very much appreciated

 I dont want to stand next to the machine in prder to vend things.

You need to upgrade the logic board to an aftermarket board that can handle higher value currency. Use an InOne board, put a MDB coin mech and bill acceptor in it and add a card reader.  To do the kind of business you want from that machine will set you back about $1000 but then you can sell anything at any price.
