Frankenbot/Repstrap update
I got the y and z axis together, very hacky, but it should work.
To power the printrboard, I will use a PC power supply, but some of the ones I have as soon as you turn them on, they shut off, ( green and black wires are shorted to turn it on) any ideas on how to get them to stay on?
Picture’s are attached
Oh lordie, the crookedness of that X belt run. Please tell me it looks better in person?
@Ryan_Carlyle it’s better in person, but I need to get it tighter for it to work properly.
To keep an ATX PSU running, there must be a load on the 5V bus. Anything that draws at least a few hundred mA should work (will need to deal with the heat) - such as a small incandescant lamp.
You don’t state in your post, but are you shorting and then opening the green and black wires? If not, it’s the equivalent of holding the power button on a computer, it turns on, then shuts off. If you have the aforementioned load to keep the power supply operational, the shorting should be momentary, not permanent.
Hmm, I have an old ATX PSU as a bench supply that I keep green and black shorted with a rocker switch to keep it on.
I think I might be wrong.
@Fred_U I have done it both ways and they both don’t work
@Ryan_Carlyle Yeah I have one that works like that, but it is being used for a different project.
@Alexander_Pritchard
I don’t think my brain cells were firing on all synapses when I wrote that. I realize now that it should be shorted on to keep running.
Correct. Green and black wire need a jumper or twist & tape… Or solder together
