Very curious to see how much this impacts print quality!
I have my doubts that it makes a significant difference in actual print quality though. Looking at polymaker for example, they specify a tolerance of ±0.02mm on diameter for 97% of the material, and the article mentions an effective accuracy of this sensor of ±0.015mm.
Maybe the best tuned perfectly calibrated hobbyist printer will see a difference, but for a regular well-tuned printer I think this is is more of a cool novelty mod.
I want to rip off bambu’s eddy current nozzle pressure sensor but measuring eddy currents is confusing
Beacon and cartographer are both Eddy current sensors and both do nozzle contact probing too. E3d has their Revo PZ with does nozzle contact probing with a peizo sensor if you’re in that ecosystem.
