RepRapPro Huxley (Sanguinololu) + LCD SainSmart Problem
Hi, I wanted to connect the SainSmart 2004 Smart LCD Controller to my RepRapPro Huxley. My problem is, that one pin is used. It´s the bed heater control. (This pin is labelled D10: it has a 5V signal...

OK..weird design... It looks like they have opted not to use the heated bed mosfet but instead use D10 to control a separate heated bed mosfet on its own board.. (probably to avoid issue with low...

Because RepRap Pro already closed their shops, I want to buy Melzi v 2.0 here:[www.amazon.com]. Can I use it to Huxley?

Probably; but have you considered upgrading to Duet electronics instead, as RepRapPro did for their Huxley kits?
View ArticleRe: Does this also Melzi v2.0 for Huxley?
Any standard controller will work. You just need to configure the firmware appropriately for the machine. The only gotcha I know of is some have a external heated bed board, which need a 5v logic signal
View ArticleRe: Does this also Melzi v2.0 for Huxley?
Right now I still want to try Melzi because I'm used to this, for example, when the wiring, but if I have a new printer so I could try Duet or other boards. I've bought it, but in a different place,...

The sanguinololu is exactly same with this. Because i am a noob with electronics, is it worthy to replace the chip, to buy a new one or replace with arduino ?

Have you verified the voltage on the 5V pin? How exactly did you connect the extruder fan? Any chance that you caused some short between 5V and 12V or 5V and GND? For solving the USB 5V/7805 issues,...

You could also try to connect a cheap USB-to-TTL converter directly to the TTL pins (RX0/TX0/DTR) that are underneath the USB plug. But first you should try to see if you can program the...

As long as you just the bootloader via serial over usb you cannot brick it. If you start playing with avrisp's then you can brick it, but even then you would really have to try! So basically just use...
