fb3 scan angle is about 80% size?

[Speculative Lasers - Dan]

I get live q error trying to edit or adjust scanners, also i notice that my scan angle is greatly reduced when using the FB3? as opposed to my other cheap chinese dac

i have checked all zones and master scan in la studio and its set to 100% but it only looks about 80%?

if i need a differential board where do i get one?

any ideas?

they are probably hooked up differential as opposed to single ended.

thats usually the quickest and simplest explanation. i believe that the FB3 wants single ended inputs to scanners. you may not have done that. and if not corrected properly, you will not get full deflection of scanners.

how do i go about changing the wiring to differential?

Mail pangolin to send you the circuit board, or at least the diagram.
You need a simple opamp circuit to make differential signals.

I have all the information, but i don't know if pangolin would allow me to make it public here.

I would like a schematic like that
