Hey there, i have a strange problem with my MKS board lately. my hardware: MKS Base 1.3 with Marlin 12V Power Supply my problem: i can connect to my mks board when usb only is plugged in, as soon as i plug in my power supply i lose my usb connection to the board. also i printed with my laptop+cura at the beginning. one day the print just stopped every time shortly after the start, so i switched to sd card printing. i already checked if the 5V is clean and if the two GND of 12V and 5V are connected. both is fine iam out of ideas and i cant find a schematic for the board anyone got an idea? :) https://reprap.org/forum/read.php?1,572094,572094#msg-572094 Wed, 22 Jul 2026 07:39:39 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?1,572094,572255#msg-572255 https://reprap.org/forum/read.php?1,572094,572255#msg-572255 There is no potential difference but when i change the chinese ps with my labor supply it does work

i have a strange problem with my MKS board lately.

my hardware:
MKS Base 1.3 with Marlin
12V Power Supply

my problem:

i can connect to my mks board when usb only is plugged in, as soon as i plug in my power supply i lose my usb connection to the board.
also i printed with my laptop+cura at the beginning. one day the print just stopped every time shortly after the start, so i switched to sd card printing.


i already checked if the 5V is clean and if the two GND of 12V and 5V are connected. both is fine

iam out of ideas and i cant find a schematic for the board

anyone got an idea? :)]]> dan_rep General Sun, 18 Oct 2015 09:00:38 -0400
