I finally got my MPCNC up and running! Only one minor issue… My X2 driver or port does not work! I wired it as shown in the dual end stop tutorial on V1 engineering. I am using the latest rambo bought in November 2019 (yes it took me 2 months to get to this part). Y2 works great. Everything but that port work fine.
Here is what I have tried:
I thought, maybe its just the motor. I switched X1 and X2 at the board, now the other motor won’t move and the original one moves now. Motors are good.
I thought, maybe I got the wrong port? Even though the wiring diagram clearly says that Z has two ports and X2 is right next to Z2, I though what the heck, give it a shot. The wiring diagram was correct, Z2 port is for Z2, not X2.
Maybe the limit switches were wired incorrectly, or maybe they are shorting out at the switch? I checked the wiring at the switches, they are wired as shown in the images on dual end stops page at V1 engineering. Middle pin not used, only first and third pins. No accidental double connect/shortage there either.
At this point, the only thing I can think of is maybe the board is bad? I read a post on here by a guy who spray painted and soldered on his board and got similar issues. I haven’t done any funny business with this board, just took it out of the bag and plugged it all in…
Does anyone have any ideas? Are there other things I should check as far as my setup should go before I try and do a return and get a new board?
Double check the end stop wiring. They should be wired to - and S, which are the middle and side pins. If you use the two outside pins, your wiring + to S which won’t work.
The endstops only stop the movement during homing, so it isn’t that.
Can you post a picture of the board, all wired up?
Are you connected with repetier host? Can you post the console log? It should show the software information. Also, whike your there, check the results on M119.
Z2 shouldn’t be used, it is wried in parallel with Z1.
We’ll try a few things, and if we can’t fix it, I’m sure Ryan would take it back. Just be honest with us. There have been very few cases of a rambo being bad, but it is possible.
I’ve posted pictures of all the wiring. The wires wrapped in green tape marks the bad port. My reasoning in thinking that it would be the board instead of a software issue is that Y2 works fine. I am connected with Repeteir host. Here is the console log (I couldn’t upload a .txt file).
I thought that the board came already with the dual firmware installed. If that’s the case, I just need to go follow the instructions on the dual end stop page?
I wonder if my Y2 really wasn’t working and that the one motor was just dragging it along.
I’ll go figure out how to change the firmware on there. I’ll post an update once complete.
Also, I’m impressed with the quick responses on here, especially during the weekend. Thanks for the support!
The only way it would have dual is if you bought a board (in a kit or sperate) and only included a dual wire set. 95% of boards leave here in series config.
X2 is the extruder port, y2 is always open to be used.
Ok I finally got everything up and running. It was the firmware that was incorrect, now that I have that on there, everything works great and I made a successful crown. Thanks for the help!
Extra points for a picture of the crown, and you’ll be officially official.
