Would be nice to see a video on how to setup a manual, end stop on these M2 Nanos. I have the ribbon cable and I am not finding any videos on how to set up a manual end stop conversion...
There are some facebook groups with some helpful info on setting up hardware. facebook.com/groups/1594446007532785 This video tends to just be the chip reverse engineering and explanations for the actual work on the board, since that wasn't well understood or documented basically anywhere.
As the results of a couple years (on and off) of work, it kinda needed to be. I'm also planning on updating it if some parts don't make sense, or if some implications aren't clear.
can you make a vid on how to bypass the steeper driver chip just get the pins for direction and drive but going to a separate stepper driver hacks.. that would be really cool!
That's entirely doable and I know folks who have done it. The best method is to drill the board and add new ends there. Then ignore the chips on the board and use a step-stick. You can simply replace the chips with ones that match the same form factor but that's a little bit harder and you must use the a few chips that fit the right factor. But, drilling and soldering the wires in is your best bet. You can do this especially if you blow off your y-chip as people are apt to do if they hook up a rotary wrong.
Hi David, great video & explanation, I would like to know if is possible to change the A4988 for TMC2209 in order to control one nema 23 for Y axis, because I want to make bigger my K40 omtech 2030 machine
Yes. Actually the form factors are the same which you may have already looked up and checked. Also, there are now M3 Nano Plus devices which are an M3 Nano but with the TMC steppers instead of the others. A friend of mine made exactly that sort of Frakenboard you're describing. www.reddit.com/r/ChineseLaserCutters/comments/f9hw79/tmc2208_silent_stepper_driver_chips_in_stock_k40/ You can find the M3 Nano Plus devices on Alibaba now, and I actually use one as my main card.
Also, another person I know exposed the leads on the board and wired in a couple step sticks. Doing that you don't even need something that fits the same form factor like the TMC2208s used in the above conversion and in the M3 Nano Plus.
Hey man nice vid! I've an issue with my laser cutter. It has the same board M2NANO. The problem is, the machine only cut well at the left side of the machine. When it comes to the right side, the display DIES, the motors keep working, but the laser does't come out. The led of the power suply doesn't light up either. Have a clue whats going on? Thank you very much!!
Pretty cool design if you ask me. It was much better to live with shittier hardware and optimize everything to the max, than to expect everyone to have powerful hardware and make bloat software as nowadays.
thank you for the video

Great, detailing and informing. Thanks.
Good job, very professional.

@@davidolsen1222 cool stuff. I've been studying Python lately. I just wrote my first program that I actually understood the whole way through.
This was very interesting, thanks :)

I found the problem... a short circuit caused by the laser pointer.
