Re: Using L297/L298 with Sanguino

I couldn't find any setting in configuration.h file. So I went through the software. There are lot of places where they write output to the step pins. If I miss out couple of places or add new bugs,...

Endstops pullup resistors always low

Hello everyone, Am having some problems with my sanguino. The endstops don't seem to work they stay in the low configuration. First I thought I might have blown up the ATmega so I ordered another one....

Re: Endstops pullup resistors always low

The endstop pullups on Sanguinololu aren't on the board. The AVR has switchable pullups on the I/O pins, which is why leaving the pin disconnected doesn't help. In Marlin Configuration.h, you need to...

Re: Using L297/L298 with Sanguino

QuoteI couldn't find any setting in configuration.h file. Use a decent firmware, then. Teacup uses macros (in pinio.h) for such things for cases exactly like yours.

Heatsink shorted pololu, sanguino can no longer connect

So, as i was placing my pololus back onto my sanguino, and I didn't notice until too late that one of the pololu heatsinks was slightly off kilter. As soon as i turned on 12v I heard that signature...

Re: Heatsink shorted pololu, sanguino can no longer connect

Thats bad... Depends on what pins you shorted, but you have probably put 12v threw your 5v 644p/1284p I/O pins... just about guaranteed to fry the MPU. Replace the 644p, and prey the FT232RL didnt get...

Re: Problem with Power Supply

Check Heatbed is about 1.2 ohms and not a short. Check power supply has at least 16 amps on the 12volt line

Re: Hotend Problem

Could be hardware or software.. If you just manually turn on the hot end and leave it does it stay on? (if no, its a hardware problem, probably broken wire, or bad fet) If it was fine make the printer...

Re: Problem with Power Supply

Hey, The resistence of my Heatbed is 0.6 Ohm (the wiki says 0.8 [http://reprap.org/wiki/PCB_Heatbed#Electronics] i think thats ok). My Power Supply supports up to 36 Amperes on the 12V line, i think...

Re: Heatsink shorted pololu, sanguino can no longer connect

Hi Dust, Yeah, the heatsink was definitely over 12v.... dang. Ok, though, a shot MPU isnt the hardest thing to replace. The board does register as a serial device, I assume that means there is hope...

Re: Heatsink shorted pololu, sanguino can no longer connect

Re testing the FT232RL, Since the board still turns up as a serial interface this is a really good sign You can test it, but shorting TX and RX togeather, see the video on soldering and testing...

Re: Problem with Power Supply

Sounds good... Plug your HBP directly into the power supply and turn on. Does that work? if so it could be the driving fet on your reprap controller has a issue. If it still shuts down... I supect...
