Description

This is a penmount designed for the Bambu Lab A1 mini and A1. It is designed as to not collide with any other printer parts so that it can remain attached when using the printer normally. It can be used for plotting PCB:s or just plotting a picture.

Tip: Check pictures for guidence if the text isn't enough.

BOM:

5x - M3x10 screw

1x - M4x20 screw

5x - M3 nut

1x - M4 nut

2x - linear bearings for 8mm rod. Outer diameter = 15mm and length = 24mm

2x - steel rods, 8x46mm

2x - zipties

1x - pullspring, 5x10mm - if you can't find a spring, use a rubberband instead.

Print BOM:

1x - zipholder

4x - slidermount

1x - screwknob

1x - penholder

1x - penmount

Assembly:

Insert all the nuts in their corresponding holes, force is needed since they are meant to be press fitted.
Insert the bearings into the penholder, also press fitted.
Insert the steel rods in the bearings and attach the slidermounts on the steel rods, also press fitted.
Attach the spring to the penholder with a ziptie.
Attach the penholder to the penmount using 4 M3 screws. Mind the orientation, slot in the middle of the penholder should be facing the m3 hole in the middle of the penmount.
Attach the other part of the spring to the zipholder using a ziptie.
Secure the zipholder to the penmount using the last m3 screw.
Attach the pen to the penholder and tighten it with the m4 screw.
Finally. Mount the entire assembly on the 3d-printer using the 3 screw holes on the machine. Mind that the existing screws on the machine are to short for this, change them to other screws with the same diameter but which are about 5mm longer.
Good luck!

Worked very well ! Made custom bambu studio profile for it Small strength issue on top screw mount tho

Thanks for posting your make. It would be exciting to see a demo too! :) Feel free to post your studio profile to help others with getting started.

Great work Gustav! Thanks for sharing :) Can you please describe how you plot a vector file? (file conversion, software used to control the printer...)

(Edited)

The designer has replied

@gustav.ferdman

Thanks! I would love to help you with that but actually I haven't had the time to try it myself for this printer. However I don't think it would be very different from doing it on other printers. You can for example use an Inskape addon to export your vector files as g-code and then make sure that the syntax matches that of the Bambu machine since there are different "flavors" of G-code. Make sure to disable auto calibration and let the machine find home for only x and y, not z. Put an offset for z as well. When your g-code is ready you put it on the sd-card and run the file on the printer. I don't think Bambu currently supports sending custom g-code through the slicer. However, it might be feasable by creating a new machine profile with custom settings. Good luck! If you have any success, please let us know here so that others in the community can gain from your success as well.

Thank you very much!

@rodrigo.benenso

are the linear bearings not overkill for the application?

The designer has replied

@gustav.ferdman

No. If it's used for making pcb's the traces need to be very precise. I can make a budget version in the future with printed bearings.

@rodrigo.benenso

Replying to @gustav.ferdman :

What is the tolerance for the pressed marker tip? Is that not the weakest link of the chain?

@gustav.ferdman

Replying to @rodrigo.benenso :

That varies from pen to pen and how strong your spring is. But yes, I can see your point. Nonetheless it's good to keep the number of possible sources of inconsistity down by making other parts better. The pen problem is simply a matter of finding a good pen with a short tip. I have tried this before on other machines with and without proper bearings. Anyway I will create a simpler version for with less none-printed hardware when I have some time over. I can make Igus bearings, perfect job for a printer. I am also planning on making a version with 5mm rods instead so that those can be bought pre-cut from Maker's supply.
