I'm taking the Flsun S1 with failed stepper board apart. I had prepared for some creative gymnastics as the steppers are at the top of the case, but then I discoverd the motherboard and the stepper boards are visible if I remove the top.

The motherboard here is semi-intelligent, as in that it doesn't try to do anything smart on its own, it's being spoon fed by the ARM Linux box behind the display.

Looking at the boards closer I instantly discover something deeply worrying: they obviously knew they had issues with the connectors, as they're hosed with silicone and then plugged them.

As any even barely sanely built printer is made with servicing in mind, here's an example of one where they just wanted to speed run the design and nevermind the poor sap who gets to service it.

After having this thing for less than a month, my strongest recommendation is for anyone to never touch the Flsun brand stuff.
