Re: Confused about 644 vs 644p - 13 years ago
Someone else will have to comment on the fuse settings bricking the chip. It may be fixable with some high voltage programming (google it). I will export the current list and will ask Joem to update the git.by SCphotog - Sanguino(lolu)
Re: Confused about 644 vs 644p - 13 years ago
If you check the wiki there is an up to date parts list on the Sanguino page. It list the correct 644p and everything else. Just pick up another. You can not control a RepRap with an Arduino alone. Nor can you do it with a bare Sanguinololu board. You need to add 4 Pololu or StepStick stepper motor drivers. This adds an additional $45 or so to the cost of the board. This brings the total price toby SCphotog - Sanguino(lolu)

Re: Error burning bootloader atmega1280 & 644P - 13 years ago
The current Sanguino bootloader will not work with an ATmega1280p. We are working on a fresh bootloader for the 1280P that will make it a drop in replacement for the Sanguinololu 1.2-1.3a. It should be in the SL git within a few weeks. That tutorial is mine (both the wiki and TheMakersWorkbench.com (my site)) I have burnt 5 ATmega 644p using that method so it is sound. I will try it with a Ardby SCphotog - Sanguino(lolu)
Re: Getting electronics manufactured/bulk ordering - 13 years ago
And this is my problem with a lot of the current devs. They scream "ITS NOT FULLY OPENSOURCE" when any of us talk of building a RR motherboard based around the chipKIT boards or any other Microchip PIC32 based board. If you mention it in the main RR IRC chat and you get a 15-20 minute lesson / arguement on how RepRap must be 100% OPEN and no single point on any design should be closed. But then wby SCphotog - Controllers

Or one could download a firmware like SJFW and ditch the PC to printer connection all together. The PC is only needed for the design / slicing / gcode generation.by SCphotog - Controllers
Re: What to get for SD capability - 13 years ago
Hey Mike, I am sending you a PM.by SCphotog - Sanguino(lolu)
Re: What to get for SD capability - 13 years ago
$90 + shipping to the US, International shipping fee is based on location.by SCphotog - Sanguino(lolu)
Re: What to get for SD capability - 13 years ago
You will need a sanguinololu 1.3a, and a SDSL board. I have a built and working Sanguinololu 1.3a for sale and Kliment in the IRC has some SDSL addon boards for sale. I could build a SDSL board if you would rather order it all together.by SCphotog - Sanguino(lolu)
Re: Programming Bootloader - 13 years ago
If that is a resonator, those caps are not needed. Resonators have built in .22pf capsby SCphotog - Sanguino(lolu)
Re: Programming Bootloader - 13 years ago
are any of the capacitors backwards? and you do not have an arduino or access to one, correct? post a photo of the boardby SCphotog - Sanguino(lolu)
Re: Programming Bootloader - 13 years ago
No you should not need another as long as the chip is powered up by the USB cable I think.by SCphotog - Sanguino(lolu)
Re: Programming Bootloader - 13 years ago
You still need to use an external oscillator to program the chip. A 16mhz Resonator will work perfect. Follow the schematic in the link I posted for wiring up the resonator.by SCphotog - Sanguino(lolu)
Re: Sanguinololu Hot end problem!! - 13 years ago
No problem. I stayed away from the IRC for years and once I joined things were so much easier.by SCphotog - Sanguino(lolu)
Re: Sanguinololu Hot end problem!! - 13 years ago
You will get a much faster reply if you join the conversation in the RepRap IRCby SCphotog - Sanguino(lolu)

Re: Stepstick trimpot? - 13 years ago
I think you read it wrong. The current schematic just has Trimmer labeled for the trimpot.by SCphotog - Controllers
Re: The world's lightest open-source hot-end for 3mm? - 13 years ago
If you got the Vishay ones from Farnel or Mouser they do seem smaller than the ones that Nophead used. I was surprised how small they were.by SCphotog - Plastic Extruder Working Group
Re: Stepstick trimpot? - 13 years ago
I just spoke to Joem and it is a 10k trimpot. I am going to put together a Mouser Project BoM for the StepSticks here in the next few days.by SCphotog - Controllers

For Sale: Sanguinololu 1.3a fully soldered board. - 13 years ago
I have a fully soldered Sanguinololu 1.3A RepRap motherboard for sale. All you need to add is 4 Pololu or stepstick drivers and you will have a fully functional reprap motherboard. Sanguiniololu 1.3A replaces the 5v connector with a 5v regulator and includes a second header on the Z axis for use in dual Z motor setups. The board includes all connectors needed to connect your motors, end stopsby SCphotog - For Sale
Re: Tutorial: Burning the Sanguino Bootloader to the ATmega 644P using an Arduino. For use in Sanguinololu. - 13 years ago
Thanks Traumflug I have already been asked to write up a similar tutorial re flashing the bootloader to the Arduino Mega's. Apparently a lot of people have been popping up in the IRC with issues with them. So maybe it will encompass all of the AVR Variants. I more or less wrote this one to help out those who are building a SL and had no idea how to burn the bootloader, because all of the info Iby SCphotog - Sanguino(lolu)

Re: Electronics basics? - 13 years ago
A fully built RAMPS 1.4 Board with Arduino Mega, 4 Pololu drivers and Optical Endstops Runs about $226 before shipping from Ultimachine. If you are looking to save money Sanguinololu can be had with Pololus with out endstops for about $160. PM me if you want to go this route I have some for sale.by SCphotog - RAMPS Electronics

Re: howto: gravitech micro SD adapter to Sanguinololu pins - 13 years ago
Yes it may be stepping down the Vss down to 3.3 but not the logic level voltages. That must be done with an IC like You need to using something like a 74HC4050D for that.by SCphotog - Sanguino(lolu)
Re: howto: gravitech micro SD adapter to Sanguinololu pins - 13 years ago
You need to step down the logic level voltage from 5v to 3.3v which the SD card needs.by SCphotog - Sanguino(lolu)
Re: Getting motors to work - 13 years ago
Pronterface runs just fine if you follow the instructions laid out in the read me file. Install Python and then all of the addon packs in the order listed, then double click the pronterface python script and it will run fine.
