Delays

It's been a few days since my last post but I got sidetracked. After making two signs in a row without trouble I've been unable to make anything else without missing steps. So after using most of my wood I decided to try to put my old 12v PSU in series with my new 24-28v PSU. Looks like I may get to increase my feedrate but not before doing one more sign. For anyone interested this is how you hook up two power supplies together without blowing them. My new power supply stayed the same and the second already modified ATX supply had it's ground isolated from its case with some cheap plastic hardware.


Don't forget to test it's independence from ground and hook it up to a cheaper supply first just in case. If you see smoke you screwed up and need two more supplies. Then I just fed the 24-28v to ground of the modified supply yielding 36 -40vdc on it's previously 12v output. Looks like I'll be back to business tomorrow where I promise another post. price of this modification was $2.50 for plastic hardware. Old pc supplies are easily found for free in many unwanted computers.
