Hi Everyone, I am trying to better understand the new rumba board and I had a few questions: [reprap.org] It says that it can take 12-35V and can drive electronics at that same voltage. If I had some 12 V stepper drivers and wanted to drive a heated bed at 24 V, would that work or how exactly do you set what the voltage is for a particular thing? Can you just drive the steppers, hotend and heated bed at 24 V without issue or do I need to buy particular hardware for that? Since I thought the motors at least are constant power, P=IV so I should be able to use a smaller current but everything should be able to handle it, right? Thanks! https://reprap.org/forum/read.php?13,183608,183608#msg-183608 Thu, 12 Mar 2026 16:11:45 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?13,183608,183608#msg-183608 https://reprap.org/forum/read.php?13,183608,183608#msg-183608 I am trying to better understand the new rumba board and I had a few questions: [reprap.org]
