I currently have a G540, 4 x #23-305-DS8A (hobbycnc stepper motors), with a 24v DIY power supply from hobbycnc. The problem is I think I am too under powered because I keep receiving an error when doing long gcode programs in Mach 3.

So my question is would a 48v power supply be a good fit for my set-up? And if so what brand will give me the biggest bang for the buck?

Thank you for your time
