Re: Should i add additional 12v for each motor
Those are low current 12v plugs for always on fans.

Hi everybody, thought I would share a weird problem that has been happening with my printer. I use the Sanguinololu controller obviously, and all is well - models are being printed as well as they...
View ArticleRe: Printer does not move in Z direction on large prints, suspect motherboard
What does the G-code do? Are there actual Z movements sent? What does the controller think where it is? Sending M114 should report what the G-code commands.
View ArticleRe: Printer does not move in Z direction on large prints, suspect motherboard
Well, what I have checked so far: 1) Z movement codes are present in the file just like in any other files - Z lifts, offsets, Z positionning at start of layer.. 2) Octoprint shows Z layer changes...

OK, so you loose steps. Likely you can hear the motor beeping when it should move. Things to check: - Allowed maximum speed for this axis in your firmware, set it as low as 2 mm/s = 120 mm/min to be...

Marlin and Teacup firmware work on this board, too. Just saying.

Dust, once again thanks a million. I'm more used to working without IDE's so just jumped at the Makefile when I saw it. The project does build fine. Thanks again.

View ArticleRe: Sanguinololu has 2.5v on the 12v side
I don't know how helpful this late reply is but it is much easier to cut the 5v wire on your usb cable and isolating the wire. I am slowly realizing how weirdly designed this board is.

Hey guys new to the forum and amazed by all the help I've gotten So I noticed how dang hot the linear regulator gets on the Sanguinololu and was wondering if anyone has tried a switching regulator?...
View ArticleRe: switching 5v regulator
issue is not the regulator... issue is both the pc and the power supply attempting to supply power.. see [www.reprap.org] for a lot more info and methods to fix it.

Dust thanks for the response. I am aware of the issue and I took care of, at least the shutting down of my computer by clipping and isolating the 5v pos of my usb cord. Yet the linear regulator is...

Unlikely the Sanguinololu developer will notice a posting here. We have a wiki and a Github issue would be even better.
View ArticleRe: My mods for curing 5V USB/7805 problems on Sanguinololu 1.3a
I had done something similar to my Sanguino, but put the diode on the 5V output of the regulator instead of the input. I used these surface mount schottky diodes and soldered them as shown in the...
View ArticleRe: My mods for curing 5V USB/7805 problems on Sanguinololu 1.3a
It's good to see that we both approached the problem in (almost) the same way :) If the diode is on the 5V side of the regulator, it decreases the 5V by the diode's forward voltage, whereas if it's on...
