Roughly translated: I bleed, pololu. [b]Current revision: 0.7[/b] Updated March 3, 2011Attached to this post are board and schematic images, or go to http://imgur.com/a/6IjD8 Here is a project I've been working on. I would like a nice clean board to control my currently un-born Reprap, and due to its cost and simplicity I've chosen to use the [url=http://sanguino.cc]Sanguino[/url] Arduino compatible board paired with a set of [url=http://www.pololu.com/catalog/product/1201]Pololu Allegro A4983 Stepper Motor Driver Carrier[/url] boards. In order to keep things tidy, I've mushed all this into one board. [b]Update![/b]The revision 0.6 PCBs have been shipped! Now for their trek across the Pacific.... In order to keep prices cheap, there will be a surplus of these boards. hit me up in #reprap if you want a sample. And to source the parts I've created a parts list on http://www.mouser.com/ProjectManager/ProjectDetail.aspx?AccessID=23049dc03a - please note that the 0.6 revision does not have pads for the voltage regulator, and in order to be powered by USB bus, a greenwire must be soldered. Oh, here's a pic of the 0.1 board assembled, the first prototype (they grow up so quickly...): [img]http://i.imgur.com/NZ0se.jpg[/img]Two more pics at http://imgur.com/a/gq4rt [b]Features:[/b][list]*Small design - board is 100mm x 50mm (4" x 2"), 2 sided, a bunch of vias (DIY routed 1 sided design in the works) *Sanguino clone, Atmel's ATMEGA644 *Up to 4 Pololu (or Pololu compatible) on-board (X,Y,Z,Extruder) (A4983 without voltage regulator) *Supports multiple power configurations:---Logic & Motors supplied by ATX power supply (needs molex harddrive connector, and optional 4pin atx connector for additional 12v)---Motors supplied by 5mm screw terminal (7v-35v)---Logic supplied by USB bus (if connector is installed)---Logic supplied by optional on-board voltage regulator (molex harddrive connector cannot be installed at the same time) *Supports multiple communication configurations:---FT232RL on-board for USB connectivity---USB2TTL header is available for FTDI cable, or BlueSMIRF bluetooth module *Edge connectors for all wire connections, for vertical jumpers or right-angle tidyness, with or without polarizing tab *Silkscreen for connectors on both sides of the board, facilitating bottom cable connections for even more tidyness *Sanguino extra pin header for expansion (6 analog IO and 4 digital IO - two for uart2, and two PWM pins) *All through-hole components (except FTDI chip) for easy DIY soldering *2 thermistor connectors with circuitry *2 N-MOSFETs for extruder/bed, or whatever *Selectable 12v/5v endstop voltage[/list] Please let me know what you think, or if you have any feature ideas, or see any mistakes, or if you're interested in contributing. [b]Revision history:[/b] [B]Rev 0.7[/B]Added footprints for voltage regulator for those wanting to use laptop power brick, etc. The vreg component footprints are hidden under the ATX power supply for space saving and to prevent both from being in use. Enabled USB bus power for logic side. Connected the 5v pin on the USB2TTL header so that either a: ftdi cable can power the board, or b: The board can power a bluetooth serial module (bluesmirf). [B]Rev 0.6[/B] Made changes suggested regarding putting power pin in the middle of endstop sense connector. Shrunk board to metric specifications for boardhouse - board size now 100mm x 50mm - just a tad smaller than 4"x2" Increased spacing between connectors to facilitate polarized or locking connector types / wire headers Changed orientation of MS1/2/3 jumpers to (hopefully) make it easier to remove / put on, and give more room to the pololu decoup caps Sent design to boardhouse for prototypes [B]Rev 0.3[/B]MS1/2/3 for each motor separated. Unfortunately the best place for this to go is under the pololus, needing you to remove the pololu to change it's microstepping settings. Oh well, I'm hoping this is a set-it-and-forget-it type of thing. Added optional 4-pin atx 12v connector to support large hotbed or extruder loads, up to 20A. 3A if just using the hdd connector Adjusted schematic to put MOSFETs gates on PWM pins for less software intense temp control. Moved endstop connectors to other side of board. Added 12V power connectors in their place, for always on fan, or whatever. Watch out for current rating. Maybe a couple of fuses is in order.... [B]Rev 0.1[/B]First prototype, first design, first PCB ordered, first assembled, etc. Pics: http://imgur.com/a/gq4rt</description> <link>https://reprap.org/forum/read.php?158,73456,73456#msg-73456</link> <lastBuildDate>Wed, 08 May 2024 22:09:28 -0400</lastBuildDate> <generator>Phorum 5.2.23</generator> <item> <guid>https://reprap.org/forum/read.php?158,73456,243320#msg-243320</guid> <title>Re: Sanguinololu: Sanguino + Pololus - Rev 0.7 X(</title> <link>https://reprap.org/forum/read.php?158,73456,243320#msg-243320</link> <description><![CDATA[ Hi all, I am a complete newby I bought my red self assembly kit from Ebay scitechsupplies made it up as per wiki all seems fine, when i plug in to usb the led lights, I installed the FTDI driver but I canot connect to the board with either ardurino 0023 or pronterface, the bootloader is supposed to be pre-installed but my doubts are growing so I tried to burn the bootloader again useing ardurino 0023 with the result of an error message to the tone of cant find atmega1284p. in ardurino my board is set to sanguino with atmega 1284P com port 8 and th burn process errors out as said.<br />Any suggestions please.]]></description> <dc:creator>papakel</dc:creator> <category>Sanguino(lolu)</category> <pubDate>Sat, 07 Sep 2013 04:56:12 -0400</pubDate> </item> <item> <guid>https://reprap.org/forum/read.php?158,73456,171610#msg-171610</guid> <title>Re: Sanguinololu: Sanguino + Pololus - Rev 0.7 X(</title> <link>https://reprap.org/forum/read.php?158,73456,171610#msg-171610</link> <description><![CDATA[ Hi i bougt a "make it red" kit with sanguino 1.3a, atmega 644a, poloulos and nema 17.from xyzprinters last spring and soldered it. but havent got time to assemble my repstrap unitll now. <br />but i wonder if there are some software kit to download prepared for my stuf?

If I didn't do that, the x or y axis will not move 200 mm when issued the command G1 X200 F6000 or G1 Y200 F6000. As I wrote, the only difference is that at 1/16 steps, it takes about twice as long to get there even though I gave the same feed rate. Increasing F further has no effect at 1/16 steps.]]></description> <dc:creator>brnrd</dc:creator> <category>Sanguino(lolu)</category> <pubDate>Mon, 04 Apr 2011 15:27:45 -0400</pubDate> </item> <item> <guid>https://reprap.org/forum/read.php?158,73456,79482#msg-79482</guid> <title>Re: Sanguinololu: Sanguino + Pololus - Rev 0.7 X(</title> <link>https://reprap.org/forum/read.php?158,73456,79482#msg-79482</link> <description><![CDATA[ No, you are correct. When you go from 1/8 stepping to 1/16 stepping without changing any settings it would take twice as long. You are essentially doubling the steps per mm when you do that so using the same settings for both configurations will indeed cause the time difference. This sounds like a software issue. Try changing F6000 to F12000 and you should see the problem disappear if the motors can keep up. I don't have any experience with MB so I can't confirm whether it will work or where you should fix your settings if it does.]]></description> <dc:creator>fireraisr</dc:creator> <category>Sanguino(lolu)</category> <pubDate>Mon, 04 Apr 2011 14:46:14 -0400</pubDate> </item> <item> <guid>https://reprap.org/forum/read.php?158,73456,79454#msg-79454</guid> <title>Re: Sanguinololu: Sanguino + Pololus - Rev 0.7 X(</title> <link>https://reprap.org/forum/read.php?158,73456,79454#msg-79454</link> <description><![CDATA[ If that was the case, then the axis wouldn't go the exact distance since it would be missing steps. When I issue a G1 X200 F6000 command from the home position, it goes all the way to the end regardless of the speed. With 1/8 steps, it takes 2 seconds with the stop watch. With 1/16 steps, it takes a little less than 4 seconds. The only way to explain this is that the MB is not sending the step pulses fast enough. At 1/16 steps, firmware is set to 80.376 steps/mm. So, this works out to 80.376steps/mm X 52 mm/s = 4180 steps/s as the maximum for the MB/firmware. Is this a firmware or microcontroller issue?]]></description> <dc:creator>brnrd</dc:creator> <category>Sanguino(lolu)</category> <pubDate>Mon, 04 Apr 2011 11:41:13 -0400</pubDate> </item> <item> <guid>https://reprap.org/forum/read.php?158,73456,79451#msg-79451</guid> <title>Re: Sanguinololu: Sanguino + Pololus - Rev 0.7 X(</title> <link>https://reprap.org/forum/read.php?158,73456,79451#msg-79451</link> <description><![CDATA[ It's a limitation of the motors you are using. Your drivers can provide incredibly fast signals, so fast that the motors can't keep up. That's why if you used the default reprap firmware and only changed pin assignments and tried to run the z axis it would ramp up so fast that the motors would stall. This had me confused when I first started too.]]></description> <dc:creator>fireraisr</dc:creator> <category>Sanguino(lolu)</category> <pubDate>Mon, 04 Apr 2011 11:30:55 -0400</pubDate> </item> <item> <guid>https://reprap.org/forum/read.php?158,73456,79439#msg-79439</guid> <title>Re: Sanguinololu: Sanguino + Pololus - Rev 0.7 X(</title> <link>https://reprap.org/forum/read.php?158,73456,79439#msg-79439</link> <description><![CDATA[ Hmm. So, the difference between them are mainly the number of IO lines and packaging?
