Have any of you guys encountered an issue where the stepper motors started acting underpowered when you heated the hotend. It seems they don't have enough torque once the hotend starts heating. This is my first printer, so I don't know what skipping steps sounds like, but if it's a pulsing jerky clicky noise coming from the motors when they try to move then that's what my motors are doing. And it's every single one. Also, the fan hooked up to the 5 amp rail also sounds significantly quieter when the hot end is heating. So it seems like everything is being underpowered. Any ideas or possible solutions to what might be going on? Thanks!
