New enclosure and sensors for sand drawing robot.

Outstanding.

[@PiefacePete46]

Excellent! I couldn't figure out the need for the felt?

[@tjhowse]

Thanks! The ball makes a quiet crunching sound as it rolls around. The felt was an attempt to make it a bit quieter.

I am looking forward to the most complete detailed assembly video. and software to create different pictures using the phone

[@MineOrebaker]

I want to make this can you help me in the software part?

[@tjhowse]

The software is more or less done. You can just grab all the python files from github.com/tjhowse/sand_drawing, copy secrets_example.py to secrets_real.py and update your info within, then ampy to dump them onto the esp32. You'll need a PCB to drive the steppers though. I'm nearly finished designing v1.1 of the board with improved stepper driver control pins and voltage regulation circuit. Stay tuned.

I would like to make one of these. Are the stl files for the 3d prints available, and do you have any instructions on how the mechanism is assembled and how to set up the software? I have checked your website and can’t find these. You have done an amazing job designing this and I would love to build one.

[@tjhowse]

I do need to update the docs to reflect the new lasercut design. I'm not sure if I'm going to go back and update the 3d printed version. I'm running long-term durability tests now to make sure nothing wears out too quickly. Once I'm done with that I'll put together some updated docs and make a build video.

[@nicksantitoro]

@@tjhowsea build video would be excellent. Thank you so much I can’t wait for it.

[@tjhowse]

@@nicksantitoro Hey! I've just pushed up DXFs for all the lasercut parts here: github.com/tjhowse/sand_drawing/tree/master/scad/lasercut_v2_dxfs . I don't yet have any updated documentation to show how these parts go together. I hope the videos will be sufficient documentation until I can put together something better.
