Upgrading ramps to supply > 5A to motors I’m using 5 DRV8825 Drivers on my ramps 1.4 to drive 5 Nema 17 motors. My motors are capable of drawing up to 1.5A and my drivers are set to accommodate Assuming I had all 5 steppers running at full power, this is a total draw of 7.5A Is there a way to upgrade my ramps board to allow for this? I’m thinking of upgrading the 5A pollyfuse & maybe one of the mosfets. Any suggestions? https://reprap.org/forum/read.php?219,890646,890646#msg-890646 Fri, 07 Aug 2026 23:48:17 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?219,890646,890647#msg-890647 Re: Upgrading ramps to supply > 5A to motors https://reprap.org/forum/read.php?219,890646,890647#msg-890647 VDX RAMPS Electronics Thu, 29 Sep 2022 01:17:48 -0400 https://reprap.org/forum/read.php?219,890646,890646#msg-890646 Upgrading ramps to supply > 5A to motors https://reprap.org/forum/read.php?219,890646,890646#msg-890646 My motors are capable of drawing up to 1.5A and my drivers are set to accommodate
