@Brook_Drumm it is definitely the entire fan mount and shroud assembly that is making contact. The mount assembly does not clear the body on its own. It does not clear by about 1mm. I can flex the Y Axis arm and force it past. This means that the shroud has no chance of having clearance even if the mount assembly did not make contact.
There is always a chance that I assembled something incorrectly. When I installed mine the instructions for installing on the simple had yet to be posted. I used the pictures of the 2014 simple as a reference. But looking back @ your site I see that there are now instructions and I think I have done it correctly.
Just take off that extra little wood piece and fasten with screws? Looks as if the wood is actually being used as the screw, so find some shorter screws, grab some nuts, and you should be good.
@ThantiK in this picture I have removed the shroud that comes with the kit in order to get a better view of things and to take the picture. Without the wood there is nothing to mount the shroud to. The M3 bolts are actually being threaded through both the first and second piece of wood so the fan would still hold without the second smaller piece I would just lose the benefit of the shroud and the precise airflow it brings.
Maybe I will open up @FreeCAD and give a combined shroud and fan mount a crack.
Well from the pictures and video I would agree with you. It is certainly the fan assembly. Is it possible the wood the extruder motor is sitting on is tweaked or bowed a little? Doesn’t look like there is much tolerance there where the fan is hitting. So if anything is off by a little it will show. Maybe use a straight edge and see if it is flat?
He is right. We confirmed it ourselves. We have incorporated a couple changed to fix it and will gladly ship free to anyone who wants the bed improved parts. My efforts to help existing printrbot owners upgrade to new equipment have been spotted with occasional difficulty and this is a good example. I will keep plugging and thank you all off your patience with me. All current shipments include these changes, eliminating the problem moving forward. With the Simple, every last millimeter is precious and we want to be sure you get everything you deserve - a fully functional 100mm cubed (even more in the Z btw)!
Thanks @Brook_Drumm for looking into this. Can I just email support to request the new parts? Will the CAD files be available so I can attempt to print my own replacement parts? Sure wish you guys had a will call counter ;-).
Yeah, that 10mm is crucial. It is the only axis that was not improved with the build volume upgrade and I noticed it when trying to print a case for my Raspberry Pi with a skirt. The skirt was causing he bed to make contact.
I was curious to know if there is anything different about the 2014 model that ships with the Alu Extruder that would prevent this from happening? The pictures on your site appear to be using he same kt that I purchased. You can even still see the square holes in part # 14 where part # E6 used to go. I was trying to determine if this issue was isolated to the upgrade kit that I purchased.
Here is a PDF of the parts. It should explain the difference. The 2014 included Alu extruder and metal
We moved the fan forward, the integrated part moves the fan right 6mm too. The extruder mount moves down 6mm, the wooden extruder comes up a few mm to bring the height on both hotends to parity. All the adjustments make good sense when you see them side by side. Lastly, the wooden extruder is modified to allow removing it without taking the y assembly apart. Kinda nice. It mounts to the same plate as the Alu now. Design tweets may frustrate past customers but will totally help future customers who end up upgrading later .
@Brook_Drumm It is a 2013 Simple and I purchased the Alu Upgrade. Did you rework the upgrade parts for the 2013 simple Alu upgrade? If so would it be possible to get the cad files so that I can print my own? Or should I just submit a request for replacement parts?
