Wow, first post of 2014… 😯
Welcome to the first installment in the modification/alterations to the PrintrBot Simple. The Simple is an upgrade over the Cupcake in many ways, but it does share limitations. These limitations were something that I was going to tackle, before ultimately deciding to switch to a different platform. But, the following limitations still do exist and I bought the Simple knowing this and hoping to improve them:
- Small build area
- Spool holder/container
- Faster printing speed
This was many months ago, and after having used the Simple over the little pockets of free time I have, I have made the following observations:
- Sometimes the firmware gets messed up. I haven’t been able to find an answer from the forum(and trying to describe this makes me sound like a madman), sometimes, when I connect the board to the PC/Mac, it does not get recognized. The only solution is to re-download the PrintrBot Simple firmware.
- I’m getting some banding on my print objects, and I suspect that it’s got to be the tension on the fishing line – either it wasn’t tight enough or the tube+sandpaper is warped(more of an oval shape than a circle).
- the print area is 100mm x 100mm, but it’s more like 95mm or 90mm. On my printer, I get some weird grinding noise when the servos when I get to 100mm.
I got new longer rods to extend X, Y, and Z axis of the printer, but the problem is that it requires modification to the body(X and Y), but the Z axis is pretty much a swapping of the rods.
However, upon finishing the job, I realize that the stepper cables on the Y axis is too short to cover the range of the newer Z axis. So, next time I’ll just get some wires to extend them.
As a bonus, I also decided to build a spool holder from PVC pipes, as that is also a job that does not require modification to the body of the printer.
The Simple is a very bare bones printer, very few places that aren’t in constant movement, and I felt it needed… protection? Later on, I plan on securing the pipes such that this can be an enclosure that can protect the printer during transport.
I’ll look into completing the z axis mod, and looking to tackling the build surface expansion
