What difference does it make that it is from 2013?

#22This is the principle behind the rapid liquid prototyping process. Positive displacement of a UV cured crosslinking polymer into a self healing substrate allows building at m/sec instead of cm/min.
If we have grant money left over at end of year, I was planning to work on a bench scale unit.

#23Earlier quoted context omitted.
The endstop can be designed with springyness. Then the process is "move towards the endstop", then "switch off the motor current, if we are pushing against the endstop spring, then we'll be pushed back a step". Repeat this process 40 times.
Nice idea. I guess you can also measure from the coil current that the motor is being stopped or pushed back.
Yup, and some modern steppers have this: https://github.com/bdring/Grbl_Esp32/wiki/StallGuard-Setup-a...

#24This is so cool! And it's from 2013, thats amazing. A very similar printing method is being explored by MIT's Self Assembly lab, I think they first published in 2017 - https://selfassemblylab.mit.edu/rapid-liquid-printing https://www.liebertpub.com/doi/full/10.1089/3dp.2017.0037
His whole website is an absolute goldmine of awesome projects and hacks. I thought this was really cool: Optical Mouse Cam: https://spritesmods.com/?art=mouseeye
I'm a big fan of this one too: https://spritesmods.com/?art=veccart&page=5
