Strain Gauge/Load Cell based Endstops

We really do have a chicken and egg problem here.

  1. We don’t yet have any electronics boards that integrate the HX717 (the faster sample rate version of the HX711).
  2. We also don’t have a good mono-block hot end design that incorporates the load cell.
  3. We don’t have 100% fully baked software (this is the bit I’m working on in this thread!)

There is another thread taking about #2 and there are some musing earlier in this thread. We don’t have a good design that integrates the load cell and would prevent the load cell from deforming in a crash. Prusa’s Nextruder block has that feature, but its oriented sideways, doesn’t mount to any extruder we have and uses custom nozzles. We could use a design that is more open source friendly for #2.

My current plan is to focus on completing #3. I’m buying the Nextruder upgrade kit from Prusa and completing my verification and testing with that hardware.
