I installed piezo probe second time, and I was having a lot of trouble getting it to trigger consistently at all (first install had no problems, and it was ultra sensitive). I took everything apart and found the solder joint on inner side of the disc had broke free. So the disc had no continuity unless there was pressure on the broken solder point. I resoldered it, reassmbled, and it's workingby jonathank - General
If someone made a multi material remote direct drive similar to Prometheus or Prusa multi-material, I would be all over it.by jonathank - Delta Machines
I installed on my Smoothie delta. Wow it's a huge upgrade from my old FSR print bed. Way higher repeatability, and a solid print bed that cannot move around. My $15 E3D clone didn't work with it's screw in Bowden coupler, so I ordered another knock off that has a proper pressed in coupler. Could small stiff springs be used to hold pretension on the piezo? Use one on each of the four cornerby jonathank - General
Since piezos detect changes in pressure, the piezo controller would need to track the min/median/max pressure change since the last time the printer board checked with it. Then it would work and not matter how slow or bogged down the printer board is with it's duties. This requires serial communication between the print and piezo controllers. Analog input could still work, but the signal wouby jonathank - General
It would be trivial to implement a crude system for this. Ideally the piezo controller would communicate not just yes/no if the endstop is triggered, but also serial communication of the magnitude of force on the print head at all times. This could also give a failsafe against printers physically falling apart mid print (the z-stop triggered, was it a small force? Or did the effector smash intby jonathank - General
It doesn't fit because the collar is too narrow and it physically cannot slide in. This is a problem with the Prometheus hot end itself, as it does not fit any of the effectors I have. I'll take some measurements after I get my cheapo E3D clone working.by jonathank - General
Received mine a few days ago. I was going to install it and a Prometheus hotend, but sure enough the Prometheus doesn't fit. The Prometheus bills itself as a drop in solution, but it has a different sized mount than E3D making it very difficult to install. So instead I'll give this a go with my existing $15 E3D cloneby jonathank - General
Sweet, just ordered one. Looking forward to removing my FSR bed that moves around too muchby jonathank - General
