My ATX PSU would not come on that I had planned to use for the power. I have a 12v 4.58A power supply that would like to use until i get a new PSU in to finish the build. I seen that the recommended rating is 5a on 12 volts. Did i miss something or could this smaller PSU work until i get the larger one in? I am not going to be running full time but want to get motors wired and functional.
Any tips would be greatly appreciated.August 16, 2017 at 8:24 am #41467
Are you 3D printing? If not, then that 4.58A PSU would work fine. I’m also assuming you aren’t powering your spindle/router with that same supply. 4.58A is enough for the motors, drivers, and controller.

Last time I checked with all the steppers running and a hot end heating is was pulling [email protected] once the hot end heats up this would be even less. I should run this test again to verify (2 1/2 years later) but you should be fine.August 16, 2017 at 11:00 am #41495
Sweet! I will not be doing 3d printing at this time or on this PSU. the spindle has it own PSU..
thanks for the quick feedback.
