Re: Help! overheated pad (soldering)
I replaced the cap, and soldered the wire across. I was surprised that this gave me such a problem after managing to solder the USB breakout board! Anyway, thanks for all of your advice, I think it...

I've managed to install the Gen7 components into the Arduino IDE. I can select Gen7 with ATMega1284P and 20Mhz. 2 different serial ports have shown up dev/tty.usbmodem1d11 and dev/cu.usbmodem1d11 I'm...

Timeout means, there's no communications happening at all. Possible reasons: wrong baud rate (should be 115200), no bootloader on the ATmega (if you have a factory fresh one), messed up USB (unplug,...

Shes's alive! It was a hardware problem! I didn't have 5V on pin 9, I corrected a bridged joint and as soon as I applied power the SetupTest ran. The heater LED isn't blinking, but I'm a long way from...

Hey all, Since I've determined I don't have the programming chops to port firmware to the Due, I'm just going to use Smoothie. I happen to have an LPCXpresso 1769 that isn't up to anything, so I've...

I saw his post on the Smoothie forum, but it looks like he actually went with an Arduino Mega. Or, if there is an LPCXpresso version, I couldn't find it in the linked repo or any of his other public...

Just downloaded and took a look, for a quick check. I think this is second board i see with inverting buffer on mosfet gate, i hope you realize that the default state when the pin is undriven, is to...

Btw, the gnd path from mosfets goes through the other side of the board, like through each gnd pin of the stepper module. Because of how 12v line is routed. If you click highlight net and click on the...

Sanguish is in Beta! The initial 20 boards from the board houses have passed the test. I just completed a print that lasted over an hour and had no issues. That was with 2 amp steppers with no cooling...

Wow, thanks NoobMan! Lots of good advice. No, I did not realize that this layout would invert the gates. I took it from the Gen7 development thread. The inversion was mentioned a little later in the...

Gaah, I've given up trying to get that link formatted correctly. Oh well. I was just checking Pololu's site, like you mentioned, and looked at my schematic again. I don't think the 10k pullups are an...

Wow $40. That's impressive. QuoteNote: The enable line is inverted from the way it works on the Pololu drivers so this MUST be changed in firmware before powering on the 12V to the drivers, otherwise...

Hello everyone. So I am new to the rep-rap and 3D printing in general, but have wanted one for a few years now. I have slowly been collecting parts to piece together my own 3D printer. Being limited...

It's just that I'm selling them at about cost to speed the beta test process along. I imagine that a kit would go for $50 to $60 unassembled once the board is out of beta given that the parts cost is...
