I received my Snapmaker 2.0 A350 early this week. I started with 3D printing an all went fine (mostly). I decided to test out the laser function. Installed the laser toolhead and bed, and as soon as I turned on the power, the laser head went BANG and smoke shot out of the laser hood and cable con…

I see what you mean about the cable ends. It was a poor design choice to make the connectors so symmetrical. But I’m absolutely sure that the head was not plugged in backwards. I distinctly paid attention to having the locking tab facing the right side of the machine when I plugged in the laser h…

Depending on how tech savy and willing to void your warranty, have a look inside the Controller/ Module? There are level shifters on the Enable, Step and Dir lines inside the controller. The CNC module is controlled over CANbus which looks like its intact, Heating and Probing on the 3D Head is also …

Streupfeffer, THANK YOU for this information about the CAN bus and the controller. This supports my (unfortunate) suspicions that the controller has been damaged. Indeed, the CNC head functions, but I still can’t get filament to feed in the 3D head. And thank you too for the link to the level shi…

If your lucky only the levershifter in the Controller is dead. I wouldnt be sure what happend in teh Laser though. I can get you pics of a functioning one, if you have clearly burnt parts, doing board level repair, not so sure if possible. The Module Sourcecode isnt available so if the Module MCU is…

[image] robinweb: I can get Snapmaker to offer me an alternative (like honoring the warranty, or at least being willing to sell me replacements at a reasonable cost). Snapmaker should warranty the issue, but if it boils down to it, i can tell you that the laser module is priced at $154, 3dp m…

May this helps you further: [image] Printing at 951C fire Snapmaker 2.0 Hi Edwin, I swapped it out and the box went up in smoke. [IMG_2260]

Thanks Moose, those prices are not ruinous, and I would definitely rather buy replacements than spend my time on board-level repairs. I’d prefer though that SM honor their warranty, and I’m working on them. They are now directing me to diagnostics for the print head stepper motor problem. Does any…

I am away from my machine, but am pretty sure the ports do have labels on them (they may be just hard to read in some light)

There are labels engraved or silk screened on the face with the ports, look a little closer maybe. move the rubber cover maybe

You can also find an overview on GitHub: Controller Hardware Link Following that depiction the second port from the top is the Add-on port 1

Laser toolhead went BANG!
