Thank you now i know why my 7 segment doesn't work. i tried the new simvim its working fine. but for me for now its complicated unlike ardsimX :)
one more question if its ok.
i also have laser cutter. like what i said im trying to replicate what you did. what procedure did you do to engrave on 3d printed button/ rotary knob?
i tried to engrave on 1 rotary knob but it was not center unlike yours. thats why im researching youtube and internet some technique to do it. but no luck.
thank you so much.
