Just found this sensor to adjust extrusion rate real time, so it should allow better prints.

Perhaps this should be added to spiderbot as incremental update?

      I'm not in favor, but when you make your own filament it could be useful.

      Everyone can benefit, but It seems mechanical is the way to go. If you search on ebay for "digital depth gauge" you will find many different digital depth gauges.

      Most of them have a port for digital signal readout, so that means measurement can be used in micro controller that controls spiderbot.

      For 25$ one can get some decent tool that reads up to 0.02mm accuracy, 0.01mm resolution.

      By the way, it seems I could get 1KG of ABS pellets for 2Eur, and PET for 1.15Eur so buying plastic for 30Eur ABS, 50Eur PET is not an option for me.

      I found a more recent version by another designer that scans filament in both directions

      Also this uses arduino so programming the thing is more easy.
