It is the best solution. Or this rotary switch you can set for only 10 positions easily, there is a washer with such jut and move this washer to position for 10 and you have 10-pos rotary switch.



I had forgotten that MMJoy2 only supports a 10x10 Button Matrix , I actually wanted a 1P10T switch to use in CAP2 for the AV8B Nozzle Angles but could not find one, but I was aware of the Nut to allow a change in a Rotary Switch's Throw Number but I don't see something like that on this switch unfortunately ,it didn't even come with a Panel Retaining Nut for mounting. I guess I could just not wire 2 positions , but I am not sure I have 10 input pins left or can the 10 positions be wired together with 1 common to a sigle pin? ie a 1x10 matrix?





I do have some 74HC165 Shift Registers, so I guess it is time to learn how to mount one on some Proto Board and use them in MMJoy2 or do you need a dedicated PCB to mount them and wire them for MMJoy?

Thanks again for you help Erichos , it's been invaluable for me so far in this Mod.
