@zov the only direct contact detection that it wouldn’t work for is electrical since the nozzle tip is a ruby. Piezo based and strain-gauge (smart effector) will work. I think starting with hardened steel is a great choice.
Apparently, I did fry my smart effector.
I remembered I had a spare smart effector stashed away, swapped all the effector parts onto the other PCB, and everything seems to be working fine.
Now on to figure out why my print failed and jammed the hot end in the first place....
You may have a bad crimp connection in the signal cable, or the effector may be faulty. Does the green led flash when you tap the tip of the nozzle upwards? Are you using the recommended probing speed in the M558 command?
Hi @MSquared and @klcjr89,
I was just wondering how your guys brushless pumps are going? I am looking at using either one of them or the berd air pumps. Since it looks like from the age of the posts that they have been running for a while, what are your preferences as to which is better? Have the brushless ones lasted being driven by pwm?
Yup... Strong magnets will do that. Wait till you troubleshoot a BL touch and it turns out the problems were due to magnets affecting the sensor. That was a painful lesson for me. Unfortunately, I can't just flip the rods. All my magnets are orientated same direction when I put the rods together to make sure they were all consistent.
