Prusa Mendel Power supply for Sanguinololu Hi Guys, I have so far assembled together all of my hardware and basically need to install the electronics. I have a sanguinololu board and everything except for a power supply. Can some one please tell me what would be acceptable to use and what I need to know whe choosing one? I have an old Vaccum Cleaner Charger here that says output 12v 300mA. Would this be ok? Sorry I am a retard when it comes to electronics. https://reprap.org/forum/read.php?41,127681,127681#msg-127681 Wed, 14 Oct 2026 06:54:28 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?41,127681,505247#msg-505247 Re: Prusa Mendel Power supply for Sanguinololu https://reprap.org/forum/read.php?41,127681,505247#msg-505247

I have my power supply up and running now. I have my software installed and can move my motors!!! If anyone needs any help feel free to contact me as I would love to help with what I do know. I am obviously still a newbie with repraps and the electronics but can help with most other things. I have experience with commercial prototypers so I do know where most problems would occur.

Thanks for the help again everyone. Great to see a positive attitude.]]> owbridmark New Zealand RepRap User Group Sat, 14 Apr 2012 04:00:10 -0400 https://reprap.org/forum/read.php?41,127681,128653#msg-128653 Re: Prusa Mendel Power supply for Sanguinololu https://reprap.org/forum/read.php?41,127681,128653#msg-128653 Dust New Zealand RepRap User Group Sat, 14 Apr 2012 03:29:20 -0400 https://reprap.org/forum/read.php?41,127681,128651#msg-128651 Re: Prusa Mendel Power supply for Sanguinololu https://reprap.org/forum/read.php?41,127681,128651#msg-128651 NelsonRap New Zealand RepRap User Group Sat, 14 Apr 2012 03:06:38 -0400 https://reprap.org/forum/read.php?41,127681,128648#msg-128648 Re: Prusa Mendel Power supply for Sanguinololu https://reprap.org/forum/read.php?41,127681,128648#msg-128648


The red power cable in a perfect world should really be yellow (for 12 volts)

The red and black power cables lead back to a screw terminal and then to the Plug I mentioned. The plug also has the green and black shorted out. (the power on switch)



NB there are two yellow and two black going from the plug to the screw terminal, needed for the current required.
(there should probably be a third from one of the 4 pin connectors, but it has worked fine for well over a year)

The cable red and black cables to the SL are quite thick, as they have to handle 17A (if you have a heated build platform)

This sounds like a simple way of connecting my power supply. I am a little confused however (mainly because I am a retard when it comes to electronics).

Allow me to attempt to clarify a few points:

I have a screw terminal (see attached). This screw terminal is currently connected to my Sanguinololu board. It has two holes. One positive the other negative. Which two wires do I put in this screw terminal once I cut the end off I don't need? And more importantly what colour goes in what hole! I don't want to fry my board having the polarity round the wrong way.

Also once I have cut the end off I don't need, what do i do with the other loose wires that have been cut?? Surely I need to cover them somehow.

Your help is most appreciated!]]> owbridmark New Zealand RepRap User Group Fri, 13 Apr 2012 23:05:23 -0400 https://reprap.org/forum/read.php?41,127681,128631#msg-128631 Re: Prusa Mendel Power supply for Sanguinololu https://reprap.org/forum/read.php?41,127681,128631#msg-128631
All I did was get a converter plug from my local pc shop to plug into the large connector, cut off the end you dont need and use the wires from that to a screw terminal and from there to the Prusa

Then you just connect the power button line to ground and your done.

I have read the wiki page:
[reprap.org]

And am still a little bit worried. The electronics scare me a little as I don't know what I am doing. I have had complete confidence in what I have been doing up until now. Does any one have/ know of a tutorial or video I can watch to help me wire my PSU to my Sanguinololu? I am more of a visual learner so I feel a video would be best.

Any help would be appreciated as I am almost there and getting excited but still very nervous!
Thanks.]]> owbridmark New Zealand RepRap User Group Fri, 13 Apr 2012 06:29:27 -0400 https://reprap.org/forum/read.php?41,127681,128199#msg-128199 Re: Prusa Mendel Power supply for Sanguinololu https://reprap.org/forum/read.php?41,127681,128199#msg-128199 NelsonRap New Zealand RepRap User Group Tue, 10 Apr 2012 16:24:25 -0400 https://reprap.org/forum/read.php?41,127681,128097#msg-128097 Re: Prusa Mendel Power supply for Sanguinololu https://reprap.org/forum/read.php?41,127681,128097#msg-128097
I ended up getting one of these from the supplier you recommended:
