personally, i would not bother with the Printrboard. There are far better options available out there, Rumba included.

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.

I just edited/added the pic of Printer board on Wiki in my last post above and its NOT whats on any of My SD2 printers never saw it on others but who knows. the 3 pics being referred to are of a brd off an older SD2 than My original which I recieved 6 years & 2 months ago new from Solidoodle and the older printer has a couple other things My original SD2 dont as they were changed, one is a thin Cork lining inside bottom of the SD2 and the other is a thin wood panel on back to mount MB to for some reason. also the Printrbrd pic is rev F so it was a bit after the one I posted which is Rev-E. Solidoodle experimented lots while making their printers and lots of odd parts were used on some units in same month. look at the 24 SD3 factory rack pics elsewhere on this forum there are at least 12 different units with many different parts than others including Hotends and all electronics. they were behind on delivery's and improvised alot lol just sayin

Strictly talking dates the date code on that board is the 31 week of 2013. This is evident by the 1331 near the USB port and is the date code of the board house that made the bare board. Now as to when it was populated and sold to SD that would have even been months later. So best guess is this board was most likely placed on a printer in late 2013. Also this could be a cloned board cloned by the persons name mentioned on it under the open rights that SD allowed on this board. Being all SMD technology it is much newer than the original Printrboard that used through hole technology only. There is no "e" in printr for a true Printrboard.

Let me clarify for others that may read this. The boards you pictured were (not the one directly above this post) installed on all Solidoodle printer models post July of 2013 (approximately). It is commonly referred to as a PrintrBoard. It is (like most 3D printing stuff) Open source. Solidoodle simply had them manufactured with their name on it. It is easy to spot due to the non removable drivers.
Prior to July 2013 Solidoodle utilized the Sanguinololu boards for all models all the way back to serial number 2. It was easy to identify because of its removable drivers.
These are the only 2 boards Solidoodle ever used.
You are correct about one thing. The WIKI pictures that were once there are no longer. I will be sure to repost them showing the 2 different stock boards.

only pic found in wiki shows the one with motor pots etc on separate board atop MB and a printer board that says so on board & an odd partial Orange brd. this is off one of the 1st SD2 and different from the MB on my original SD2 which has the stacked boards but no micro SD and power wire screw terminals instead of socket/jack for PSU also My original dont have the pins installed to connect part cooling fan and its newer serial number than the printer this MB is from, this is the one everybody kept talking about that the motor control chips were soldered onto MB and couldnt be replaced which I thought my original SD2 had till seeing this older one. this explains why RH came with the SD and cooling fan buttons on control panel page. the printer boards I saw pics of say 'printer board' on them not Solidoodle Rev-E. 1st I have seen of this specific board. I also have seen boards with plug in processors on Motor controllers.

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.

no, the stock pulleys are MXL, not GT2, and the two are NOT interchangeable.

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?
