What should I pick for my laser controller model in laser drw settings?

What should I pick for my laser controller model in laser drw settings? I have a Nano 2016G Nano or KETAI GOLD 5. That is the only model # I can find. I have been using the B1 selection but it really seems slow. It auto finds the right s/n and the b1 is what it uses. Any help would be great

I would guess M2. The ‘2016’ implies it is relatively recent and M2 is the highest rev and most common.

This is my Board , on the top left Stands m2nano may you can Compare this with yours

Thanks for getting back Ben, your link is bad. Here is mine

I’ll try M2, thanks scorch works

Yeah! Gz!

Cant figure out how to post pic here, did you see the pic I sent you Ben

Sorry to tell but it seems this is not the same board as i have. May some other guy can told you more.

Well tried them all. Only B1 seems to work (sort of) It is very slow though

Wow, I am shocked by that. I was confident M2 would work. Thanks for the update.
