Hi Jorge, your machines is larger than the standard K40 but it does have an M2Nano control board, so installation should be straightforward.
You will need need to do a bit of configuration and tuning to get things working properly (mostly edits to the config file that the firmware uses.)
Things you will probably need to adjust include:
- The motor currents - probably need to be raised
- The max speeds and accelerations - probably need to be lowered
- The bed size for X and Y
- Homing direction - we are expecting the homing switches to be left rear, but yours are right rear
That said, the photo of your M2 Nano board shows two interesting things.
First, the leftmost connector with 5V G L on your board is where a ribbon cable connector is usually located. Can you get a photo of where those wires lead to?
Second, the larger connector on the bottom right has no wire in the LO position. Typically we’d expect the LO along with GND to be used to fire the laser. Not seeing a wire there is a bit odd.
Could you provide a few more photos, showing where those two connectors go to? The larger one should go to the LPSU (laser power supply unit) so photos of where it connects and any labels would be helpful. Photos of any control panel on the machine might also be useful.
One last thing, while a “plug and play” replacement is the goal, we always encourage our customers to have a tinkering and problem solving mindset to be able to work through any unexpected challenges that can come up. We just like to make expectations clear.
