]]>my personal experience with the SD Printrboard include a failed USB connection on one, and on another, a failed stepper driver - and with no way of replacing the stepper driver, that means the entire board is no longer any good.

the Rev E board began being used on some SD3s in 2013 and was used on all SD4s when they came out in November of that same year, so no, you will not see it on an SD2 unless someone else put it there after the fact.
ah was wondering that. so the guy just stuck his old SD3 brd in the box with parts printer after upgrade likely. so do those brds over heat easy with no heat sinks on brd mounted motor controllers? and do they have the pins for part cooling fan? maybe it would be a good upgrade for my Original SD2 if printer type was changed in firmware.
The board is a heatsink. It has a thermal plane that connects to a thermal slug in the middle of the driver to pull heat away from the driver. It works but can lead to board heating and a fan on the board would be highly advised.

]]>thought Id post pics of the parts SD2 units MB as its the rare original SD Rev-E for ref photos.
note the micro SD slot and power input socket later brds didnt have
Wrong on so many levels.
Absolutely nothing different or rare about a post July 2013 SD running that board. It is indeed a standard PrintrBoard as shown in the WIKI and commonly referenced throughout the forum.

purchase some new belt material, it is worth the cost. Belts do wear out, it is always nice to have extra on hand. just use an old one to get the length you need.

cant say I have ever had a carriage break in the spot you say this one broke.. perhaps it had been over tightened? or possibly not well printed.
but yeah a new carriage would be in order if it has cracked..
you could possibly try fixing it with a little acetone if it is printed in ABS.. I have done that before, and it works pretty well. just a cheap artist brush (the 10 in a pack for a $1 type) to brush a little acetone across the cracked area, then clamp it tight and let it sit for about a half hour or so
it broke the U shaped thin part off that holds top end of bolt the belt/fishing line pulley is on. found a post by Ward saying fishing line is hard on the carriages due to how tight they have to be to not slip.
thought GT2 belts were what to use now instead of the old MXL type? will GT2 work with same pulleys?
