Just a heads up for people looking into aftermarket prusa mk2 steppers for replacement or upgrade. They look the same, same wiring, etc but the Z axis really show their weakness.
Stay away from the off brands. I got a replacement set on the way from Prusa direct (from chat convo).
I got mine refunded, but they were super weak torque wise.
Anyone have similar experiences ?
I noticed in my recents prints that the hotend temperature cycle from 212 to 218°C when set to 215°C.
Is that acceptable ?
I feel like it's the case since I change the heater cartridge (for a basic one buyed on amazon). Could the cartridge be the suspect ?
Or is there a calibration needed ?
Thanks for you advices.
Yesterday, late, after cleaning the heatbed, suddenly the usb stopt working.
Tried another usb port, another pc, octoprint, ... no response.
So i think the usb port on the rambo is down.
I've checked prusa shop and did not find any replacement electronics.
Where do i get a replacement electronics for my i3 MK2S (if possible with software loaded)
I can print from the SD card, but on my last print i had a layer shift,
so i think replacing the electronics is the best solution.
