Selling my control board. Comes with software CD, USB dongle and the M2 nano control board.
I’m sorry to hear it didn’t work out for you.
@raykholo ya right. Considering I used your board to replace this :-). Hehehehe
You think there is a market for them? I just happen to have one also! Grin… I’m watching your e-bay but I wouldn’t put mine up for sale until yours sells as a courtesy.
I saw on ebay - people are selling them for $99+, not sure if anyone has bought them.
I might be in the wrong business…
Is there a way to adjust the steps per mm on thsese boards?
Not that I know of.
@Steve_Clark thanks 
I think lots of people have these boards laying around. I even offered it for free to someone
Sold. 
@Dushyant_Ahuja great business model. Sell your useless stock controller and replace it with a proper one! Maybe you can end up with a positive cash flow
@Paul_de_Groot hardly. Took the first offer I got. Sold it for $60
@Dushyant_Ahuja Ahh I assumed you sold it for the full listing price
I’m amazed.
There’s a market for these, not a big one but people do buy them.
@Madyn3D_CNC_LLC to tell you the truth - I wouldn’t have bought it for $60 when you can get the @Cohesion3D mini for about a $100
@Dushyant_Ahuja No, definitely not a wise move lol, the Smoothie upgrade is well worth the extra 40 bucks.
I think some of the people buying the Lihuiyu control PCB’s are hacking them or whatever to drive plotters or animatronics, or maybe just experimenting with them. I don’t think the laser folks are buying them, unless they are unaware of Smoothie/Cohesion.
Or maybe some people are nervous about stepping outside of what they’re comfortable with. I can be like that sometimes when it comes to CAD software.
I see them sell pretty fast at a decent price most of the time.

I have to disagree here. For someone who solely does engravings I loved this board. It was so quick and easy to just save a regular Illustrator file, open it up in corel laser, hit the engrave button and It’s on it’s way.
I just recently upgraded to to the coehesion3d because I couldn’t figure out how to adjust the steps/mm on the Nano board. Mine was off about 2% for some reason.
With the cohesion I have to use the god awful laserweb app now. It isn’t really user friendly and takes forever to set up a job. If you have to generate slightly complex g-code it takes SEVERAL minutes. I could go on and on… I also miss how as soon as I turned on the nano it would home and then go to where I had it set on the x and y for my custom zero automatically.
@laurence_champagne you don’t need to use laserweb. You can use any GCode generator. That’s the beauty of open source.
Also, you can setup a startup GCode for the cohesion3d board so that it homes and goes to your custom zero automatically. It’s pretty simple.
Worst case - I’m sure there are many people on this group who would gladly sell you their boards.
