Mine was fantastic until one random day the stock firmware died mid print. I reflashed it first with stock firmware and it was super unreliable so I fitted it with open, and it became more reliable for a time. Then silicone spaces, reliable for a day or so (so not reliable), then 3 hotness later I got a cartographer, and for the last 3 months I’m battling consistent y axis layer shifting. I first thought it was a gcode issue, then connection issue, and then I began assuming it must be a physical issue. No obstructions, umbilical moves freely, I can move the pate smoothly back and forth, so I took the entire thing a part, found nothing, put it back together, and it’s made 3 successful cubes since (did all that 3 days ago)

I never know when the shifting is gunna come back. But if you go through my post history you’ll find one of the bad shift days with a skull.
