Hi fellows! I was printing in a graber in PETG in 240º / 90º, but I had not installed an external mosfet. Because of this, my ramps burned one of their pins, user to receive the 12V from the PS to the hot bed. Then, I decided to change my ramps shield, and remade all the wiring. After this, the motors stopped to move. I have already checked the reference tension (Vref) at the drivers, and they are all ok. Does anyone have any hint? Thanks. https://reprap.org/forum/read.php?4,897436,897436#msg-897436 Tue, 16 Jun 2026 07:46:33 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?4,897436,897437#msg-897437 https://reprap.org/forum/read.php?4,897436,897437#msg-897437 VDX Reprappers Thu, 22 Jan 2026 10:34:01 -0500 https://reprap.org/forum/read.php?4,897436,897436#msg-897436 https://reprap.org/forum/read.php?4,897436,897436#msg-897436 I was printing in a graber in PETG in 240º / 90º, but I had not installed an external mosfet.
