Sorry the PSU that I'm using now is 20A. I swapped out the 15A one that didn't work. Also, I'm concerned about the Arduino MEGA I'm reluctant to get a more powerful PSU and completely fry the mega.by MMS - RAMPS Electronics
Hi, Long time lurker first time poster. I'm having some difficulty with powering the heatbed and hot end at the same time. I can power the heat bed up to temperature independently and the hot end independently. However, when I try to power both for a print the RAMPS and Arduino both suddenly turn off. Setup: - Prusa i3 clone - RAMPS 1.4 - Arduino MEGA OEM - A4988 drivers for X,Y, Z - DR8825 for tby MMS - RAMPS Electronics
