  • Also if you’re considering new hardware already I really recommend looking into surplus enterprise gear. I run my whole lab on an R730XD. It holds a ton of drives, has an IDRAC (I can’t live without it now), ECC for extra peace of mind during ZFS scrubs, and they hold an insane amount of inexpensive RAM. They’re fairly cheap on eBay or from refurbishment companies. Bring your own drives with warranties though, used drives are a headache. Servers like this can be really noisy though, I keep mine in the basement.

    I’ve briefly considered it but it is out of the question for me. Not enough space in the house and enterprise gear is way too noisy. This setup will probably sit next to the TV in the living room so it has to be as silent as possible.















  • Hello, I suggested heat creep in your last post, which didn’t end up being the issue. I don’t remember if anyone suggested it, but have you tried checking the bowden assembly, on the motor side? Whether the stepper works, or the gears wore down (I’m pointing towards this), or there are clogs somewhere in the mechanism, even some dust that accumulated where it shouldn’t had. Or did you change settings like the current limit on the steppers? If that’s controlled with a potentiometer on the main board, maybe it got turned down for some reason (if so, I’d try to understand why’s that). I don’t know how Klipper handles motor drivers where current limits are controlled in software, I know that Marlin has a dedicated submenu in the Configuration>Advanced Configuration. If you reflashed the firmware, maybe the settings where in the eeprom and did not get transfered over or got overwritten in the flashing process.

    I remembered that on a couple different printers I had the same problem as you, and it came down to damaged/untightened nozzles (which you excluded already) or wore down gears or, on the printer I’m working on right now, too low current limits which made the stepper skip steps somewhat randomly
