Author: i <EFZ-Lohmen@web.de>
Date:   Sat Nov 12 08:43:45 2011 +0100

    added header for extension board

Author: i <EFZ-Lohmen@web.de>
Date:   Fri Nov 11 19:13:13 2011 +0100

    conected x-axis pololu and power on/off to other pins of the ATmega to make space for a header

commit 32d91aad265d11427a5262155a1d01dc73ab2bc1
Author: i <EFZ-Lohmen@web.de>
Date:   Fri Nov 11 18:55:28 2011 +0100

    added SPI header for extension bord

commit 44efed7b90c2b33fafc66730d147233af81d8f39
Author: i <EFZ-Lohmen@web.de>
Date:   Fri Nov 11 18:22:03 2011 +0100

    moved the endstop connectors and cleand up the schematics

commit 2964c946f6c620b781d3a073eef7034eaf626a65
Author: Markus Hitter <mah@jump-ing.de>
Date:   Sun Oct 30 18:43:22 2011 +0100

    Board: replace the big motor connectors with Molex KK 100 ones.
    
    This is pretty much the standard now, as Sanguinololu and
    RAMPS use these for quite some time.

commit f38c83e50278ec1b63a476f14dc7d960a3ddcdaa
Author: Markus Hitter <mah@jump-ing.de>
Date:   Sun Oct 30 18:10:34 2011 +0100

    Add a Molex KK 100 4-pin footprint.

commit b1cbe305029f1574a2602e84bc472e5d30a8cdc5
Author: Markus Hitter <mah@jump-ing.de>
Date:   Sat Oct 29 20:51:04 2011 +0200

    Board: move the ICMP header to the left of the ATmega.
    
    This saves a fantasic 3 wire bridges without drawback or
    functionality loss ! Also, try to leave room in case
    C18 moves into the ATmega socket.

commit 6ae7afdf1537cd1f5b3450777725f3e853191fb9
Author: Markus Hitter <mah@jump-ing.de>
Date:   Sat Oct 29 19:56:15 2011 +0200

    Board: remove tha ability to feed 5 V through the serial connector.
    
    This is not of much use and had the unfortunate side effect of
    destroying the USB-TTL converter while plugging improperly.

commit c46d844f571dd93ca7740391667a4ecc919b6268
Author: Markus Hitter <mah@jump-ing.de>
Date:   Fri Oct 28 20:40:44 2011 +0200

    Board: remove max endstops an rewire the remaining ones.
    
    Maximum endstops will eventually go onto the extension board.
    There is now no longer a conflict between some endstops and
    the ICMP header. Should be simple to kook up an SD Card reader now.

commit 74f6d311092c02b6353720c6c256e27e8a747abe
Author: Markus Hitter <mah@jump-ing.de>
Date:   Fri Oct 28 20:26:05 2011 +0200

    Board: move the crystal inside the ATmega socket.
    
    Obvious advantage: it saves board space.
    Less obvious: it's easy to keep it there while maintaining
    short tracks to the CPU's clock input.

commit c8c5a78d72faea0198a9627b56eebb3fa5b19ac4
Author: Markus Hitter <mah@jump-ing.de>
Date:   Fri Oct 28 20:07:49 2011 +0200

    Add pockets to the DIP40 footprint.
    
    This gives a good hint where we can place components within that
    socket.

commit 876ee67e69196100ab3ccc6b6a7c98e989a47321
Author: Markus Hitter <mah@jump-ing.de>
Date:   Wed Aug 17 00:33:22 2011 +0200

    Add a HowTo for making a release.

commit 9d40962f1e464bd97f07803a62aa520c390d6242
Author: Markus Hitter <mah@jump-ing.de>
Date:   Tue Aug 16 22:41:52 2011 +0200

    tools/make-release.sh: git also requires a plain git push.

commit a9c492d15ee930a92b5fdb0ceec59f3311788237
Author: Markus Hitter <mah@jump-ing.de>
Date:   Tue Aug 16 22:38:10 2011 +0200

    Make Release 1.3.1.

commit 5461712e944de8d992091d75973ca12da74bbda6
Author: Markus Hitter <mah@jump-ing.de>
Date:   Tue Aug 16 22:34:35 2011 +0200

    arduino support: adjust boards.txt to new fuse settings.

commit 912777ffc3439c8246e34a3f2bb70f83c7204c40
Author: Markus Hitter <mah@jump-ing.de>
Date:   Fri Aug 12 15:06:07 2011 +0200

    Add data sheet for the Bootloader protocol.

commit 812252a732310d4d97be5b378ec2bca28bf21bec
Author: Markus Hitter <mah@jump-ing.de>
Date:   Fri Aug 12 14:54:34 2011 +0200

    Bootloader: reconsider the page erase strategy and save 60 bytes.
    
    As avrdude always sends complete flash memory pages, there's no point
    in tracking distinct counters for pages to be erased vs. pages to be
    written.

commit 34de8d68a717c4744f40724c8f04b4c4343f7ecb
Author: Markus Hitter <mah@jump-ing.de>
Date:   Fri Aug 12 14:47:28 2011 +0200

    SetupTest: turn the other heater LED off while one is blinking.
    
    Formerly, the status of the second heater was undefined, which sometimes
    led to user confusion.

commit d9061450c527be6287e7ead1ac0cd615b2b0166e
Author: Markus Hitter <mah@jump-ing.de>
Date:   Thu Aug 11 15:20:16 2011 +0200

    Bootloader: take measures to not accidently overwrite it's self.

commit 80f55a0a701a1d6c7a7135cd63920b7eeb8bd399
Author: Markus Hitter <mah@jump-ing.de>
Date:   Thu Aug 11 15:14:02 2011 +0200

    Bootloader: remove support for lock bits.
    
    This is a somewhat questionable feature, as a programmer is required
    to clear these lock bits again.

commit ac9565a39b9a8eef453c5c2d57320dbd61b78b2a
Author: Markus Hitter <mah@jump-ing.de>
Date:   Thu Aug 11 15:12:27 2011 +0200

    Bootloader: replace tabs with spaces, remove spaces at line endings.
    
    This is a purely cosmetical change.

commit 3a4c77621309f5f03ee099df7a81da6eed1dc6ac
Author: Markus Hitter <mah@jump-ing.de>
Date:   Fri Jul 22 00:56:40 2011 +0200

    Make Release 1.3.

commit 95dd0c78ac41dbbe451e6e9db0446ac0e1a7db71
Author: Markus Hitter <mah@jump-ing.de>
Date:   Fri Jul 22 00:16:59 2011 +0200

    tools: refine release making script a bit.
    
    Git apparently deletes emptied directories now, so we have to
    uncommit the old release first, then clean up the file system.
    
    Also, .zip and .png are ignored by git now, so we have to
    force-add them.

commit ca15f8f19c64fbab737a9eae90cf63f90196473c
Author: Markus Hitter <mah@jump-ing.de>
Date:   Thu Jul 7 22:34:10 2011 +0200

    Add a small setup test firmware.
    
    This is for use right after assembly, to make sure basic things work.
    Nothing fancy, but it compiles in the Arduino IDE.

commit 792a5ee05b685a44cab80b078608b2a18848ee42
Author: Markus Hitter <mah@jump-ing.de>
Date:   Wed Jun 29 14:39:52 2011 +0200

    Board: fixed the designator of the Pololus on the silk screen.

commit 2378cb46d4194a733f801355a38173b90568a73c
Author: Markus Hitter <mah@jump-ing.de>
Date:   Wed Jun 29 14:07:29 2011 +0200

    Board: fix a misaligned mounting hole.
    
    The misalignment was probably introduced unintentionally.

commit ffa59d31df1eb93aad79d8be28443c2f9a53348b
Author: Markus Hitter <mah@jump-ing.de>
Date:   Sat Jun 25 21:08:53 2011 +0200

    Endstop: add a 'E' and 'D' sign to the TCST1103/2103 footprint.
    
    The previous one wasn't unambiguous and nobody told me for several
    months ... uäääh!

commit ef706ebaa7dedc025fe000ebbc6d01ff11667b81
Author: Markus Hitter <mah@jump-ing.de>
Date:   Thu Jun 16 00:02:00 2011 +0200

    Board: aligned Temp connectors with the surrounding connectors.
    
    Another cosmetics without functional change.

commit fc7d5cc8552fe49e0e00a98fac628c85bb8b42e0
Author: Markus Hitter <mah@jump-ing.de>
Date:   Wed Jun 15 22:50:11 2011 +0200

    Board: align CONN3 to CONN2.
    
    Also purely cosmetic.

commit 0bad2c43e407760cf363a7bc049bfef7738e5741
Author: Markus Hitter <mah@jump-ing.de>
Date:   Wed Jun 15 22:33:43 2011 +0200

    Board: align C1 with the nearby connector.
    
    Just a cosmetic change.

commit 0b233abc2a3e14407c6c0c81576a4b570cf0c6b6
Author: Markus Hitter <mah@jump-ing.de>
Date:   Tue Jun 14 17:47:10 2011 +0200

    Board: bump printed version number to 1.3, note new licence.

commit 87b6a8a5427ff52b914396f72c9138b3d5e3bb39
Author: Markus Hitter <mah@jump-ing.de>
Date:   Sat Jun 11 11:00:41 2011 +0200

    Removed two footprints which are likely never used.

commit b371fd7b582dd5873ec48a2781ce9a31b77b1684
Author: Markus Hitter <mah@jump-ing.de>
Date:   Sat Jun 11 10:58:28 2011 +0200

    Board: make the MOSFETs upright.
    
    This should allow better cooling and attaching a heatsink. Effectively,
    it just replaces the silk of the footprint ...
    
    Also made the GND trace there even thicker.

commit 0ebc6ca6a51ef424171d0f222a7873911ea184bb
Author: Markus Hitter <mah@jump-ing.de>
Date:   Sat Jun 11 09:02:48 2011 +0200

    Board: remove the Debug LED again.
    
    This was added too early, as this pin is also used for the X_MIN
    endstop. When introducing SD card support this endstop is expected
    to go elsewhere, though.

commit 944b14ede3cc9d782cc00e328e9197e429942847
Author: Markus Hitter <mah@jump-ing.de>
Date:   Wed Jun 8 23:10:57 2011 +0200

    Both PCBs: raise minimum track width to 30 mil.
    
    Was 20 mil before. According to users of the toner etching method,
    wider tracks are more reliable. So, increasing track width without
    lowering minimum copper track (important for isolation milling)
    is a good thing.

commit 06cefc8fd030718a100382d2d57676fa740e708e
Author: Markus Hitter <mah@jump-ing.de>
Date:   Wed Jun 8 22:16:34 2011 +0200

    Board: same clearance against copper planes for all tracks (32 mil).
    
    The endstop PCB was already fine.

commit 47c3431476001517dd9c3d7af02dc6eef2158a30
Author: Markus Hitter <mah@jump-ing.de>
Date:   Wed Jun 8 21:47:38 2011 +0200

    Board: made traces from the MOSFETs a bit shorter and thicker.
    
    There's a lot of current and this also makes a bit more room.

commit ab146d9e99d91dc51ff96e892f91eeee76b2a7ca
Author: Markus Hitter <mah@jump-ing.de>
Date:   Wed Jun 8 21:21:35 2011 +0200

    Board: made drill holes for the Molex 4 Pin and Molex 156 both 1.6 mm.
    
    This is a bit smaller than recommended by Molex, which takes account
    for the fact Gen7 is single sided. Five drill sizes now, which is about
    as good as we can get.

commit 75c1edd8683a7e3e55efa0049108d81f777c4ca1
Author: Markus Hitter <mah@jump-ing.de>
Date:   Wed Jun 8 20:48:22 2011 +0200

    Board: reduced the ATX24's drill size to 1.3 mm.
    
    This was 1.4 mm and takes account for the fact Gen7 is single sided,
    so no solder can flow into the hole anyways.

commit 10008983f1e746a15a886b646a99265ec089915c
Author: Markus Hitter <mah@jump-ing.de>
Date:   Wed Jun 8 13:40:14 2011 +0200

    Board: reduce the drill size of screw terminals to 40 mil / 1.02 mm.
    
    Both, the screw terminals coming from Reichelt as well as those
    coming with Gen2 electronics have 0.9 mm pins, so 1.0 mm is
    totally sufficient ... and yet another custom drill size less.

commit 51787c5f7846fb890bbee30c45f86af8da98eed2
Author: Markus Hitter <mah@jump-ing.de>
Date:   Tue Jun 7 20:07:59 2011 +0200

    Added data sheet for the Molex KK 156 header.
    
    These are the headers used for the motor and heater connectors.

commit c66f35c3a347c6a42e80a417581bf8312140399d
Author: Markus Hitter <mah@jump-ing.de>
Date:   Tue Jun 7 19:53:12 2011 +0200

    Board: reduced the drill size of the MOSFETs to 40 mil = 1.02 mm.
    
    In the data sheet 0.66 to 0.93 mm are specified, so this is safe.
    Seven drill sizes are left, now.

commit 6ff42288c274dfb2f48522414d08f591d14be5dc
Author: Markus Hitter <mah@jump-ing.de>
Date:   Tue Jun 7 14:43:11 2011 +0200

    Board: made the 20 MHz crystal the default.

commit 99015137dec6540e16e360bc24c051a02b8b8a6c
Author: Markus Hitter <mah@jump-ing.de>
Date:   Tue Jun 7 12:56:08 2011 +0200

    Board: removed a now obsolete wire bridge.

commit 54183e8b45a07bf28b4a2a62536ddd1b00bff8d9
Author: Markus Hitter <mah@jump-ing.de>
Date:   Tue Jun 7 01:12:30 2011 +0200

    Board: add another disk power type connector for supplying heaters.
    
    Also, the 12 volts stuff was divided into two parts. This allows
    to have different voltages for heaters and motors without making
    things more complex for newbie users.

commit 76bf7046cde4c262e2767ecbf6b4626430d8bab9
Author: Markus Hitter <mah@jump-ing.de>
Date:   Mon Jun 6 22:13:36 2011 +0200

    Board: made Standby and Debug LED yellow.

commit fad314ece216d3f46c343c3f013deda18a11fd57
Author: Markus Hitter <mah@jump-ing.de>
Date:   Mon Jun 6 16:41:44 2011 +0200

    Board: the debug LED is back!

commit 539651d06054fe1308e29ae88ed68191a0c780b5
Author: Markus Hitter <mah@jump-ing.de>
Date:   Mon Jun 6 15:08:05 2011 +0200

    Board: raise power debug LED pre-resistors to 1K.
    
    Formerly this was 180 ohms. With 1K the light is still clearly visible.

commit dae1915684d4715c0b8bd83a102fb1fc6742aae2
Author: Markus Hitter <mah@jump-ing.de>
Date:   Sat Jun 4 01:42:51 2011 +0200

    Board: replaced the footprint for the ATX20 connector.
    
    The footprint has now 24 pins for compatibility with
    ATX24 power supplies.

commit ea55def3a6d89ad1967e2865161f6f5257335409
Author: Markus Hitter <mah@jump-ing.de>
Date:   Sat Jun 4 00:43:53 2011 +0200

    Minor fix on the ATX20 symbol.

commit a803a3a125d3d32285434f55f6f2087e1455ebca
Author: Markus Hitter <mah@jump-ing.de>
Date:   Sat Jun 4 00:19:29 2011 +0200

    Removed the three-jumper, as the plans for this have vanished.

commit 676478d9dd5ae80e03b5b17f600376a1fedd4d4d
Author: Markus Hitter <mah@jump-ing.de>
Date:   Fri May 27 00:18:07 2011 +0200

    Add a few more data sheets regarding power headers.
    
    Also remove ones no longer in use.

commit 7d994eb0f72f23d41326cb84ffede6e9f4801fae
Author: Markus Hitter <mah@jump-ing.de>
Date:   Thu May 26 22:56:34 2011 +0200

    Replace 3 pin thermistor headers with 2 pin ones.
    
    This not only lowers the price by a few cent, it also allows a
    simpler routing, removes a wire bridge and makes it unambiguous
    on where the thermistor should be connected.

commit b1c957244a01351e91988985ad4e8fefc8a18dca
Author: Markus Hitter <mah@jump-ing.de>
Date:   Thu May 26 21:18:25 2011 +0200

    Add a Molex KK100 2-pin header.

commit 077ce0058d9b506651d7d65cf539371710b1d66b
Author: Markus Hitter <mah@jump-ing.de>
Date:   Wed May 25 22:20:37 2011 +0200

    Remove the I2C header.
    
    Apparently, nobody uses this, so save cost and board space.

commit 6caa8a681c04307468441c3a9995abbe9271f059
Author: Markus Hitter <mah@jump-ing.de>
Date:   Wed May 25 21:27:25 2011 +0200

    Replace the heater connectors with that new Combi-2 type.
    
    Several enhancements:
    
    - Only two pins -> less confusion.
    
    - Thicker pins -> more current possible.
    
    - You can use screw terminals.

commit ca9f6d19aeffbf538358526a7508ce3a1500194c
Author: Markus Hitter <mah@jump-ing.de>
Date:   Wed May 25 20:56:02 2011 +0200

    Remove the MOSFET for the fan.
    
    This has three reasons:
    
    1 A questionaire resulted in nobody actually using a fan.
    
    2 If you really want a fan, connect it to the power supply
      directly. Like the PSU, it will switch off at end of printing.
    
    3 Cost and board space, of course. Cost saving is about EUR 1.-.
    
    No worries, the board space will be reused quickly, bigger headers
    are already lurking around the corner.

commit 12f52eddd9a03a3b79b9f80815613f01f5569d20
Author: Markus Hitter <mah@jump-ing.de>
Date:   Wed May 25 19:48:59 2011 +0200

    Add a Combi-2 footprint, derived from the Combi-4 one.
    
    This is to be used for the heater connectors, as these draw even
    more current than the motors.

commit d3ddc97192fedf29aa10be6ce9b34d61bba05b9a
Author: Markus Hitter <mah@jump-ing.de>
Date:   Wed May 25 19:16:12 2011 +0200

    Removed the Molex .156 and the AKL 220 connector.
    
    They're no longer used and were replaced by the Combi-4 footprint.

commit 1dda1e8d53240a2b3997ccdcf999be761e4d97b2
Author: Markus Hitter <mah@jump-ing.de>
Date:   Tue May 24 00:07:30 2011 +0200

    Make use of this new combi footprint ...
    
    ... and allow the GND track near the top border to be wider, as
    there is more space now.

commit dfba
