  Hi, do you have schematics and such available for this board? It looks like it could be useful for something I'm doing.

  @Popstar No additional electronics is needed. It works as is - without any problems - just make sure you get the pinout right and put this line to configure the sensor : M591 D0 P7 C"^e0stop" L7 R50:250 E22 S1 ;pulse, disabled, 7 mm/pulse, measure every 22 sec, minimum 50 maximum 250 Also it would be wise to disassemble the sensor and "squeeze" the spring a little bit, to make the filament go through more easily, since by default the spring is too strong and puts a lot of resistance to the filament flow....

  @stuartofmt said in Precisionpiezo Problems: @arhi - Thanks for the clarification. At $35 for a new BLTouch and my currentl hourly rate working on PP (about 35c per hour) .... well - you get my drift yes, that is why I'm not using it for new printers ..it's a great idea but... @stuartofmt said in Precisionpiezo Problems: I'm curious now as to the difference between Zesty Nimble and flex3drive but that's a different thread in 99.9% cases, this question leads to a flame war and lock of a topic so I'll restrain myself from commenting. I heavily tested both and can give you my own opinion (not affiliated with any of them) in private chat if you are interested

  They are fragile. I've lost one in a head crash with the print once. Treat them gently like the precision measuring device they are and you'll be alright. Once installed, make sure the leads are secured for strain relief during operation and it'll be fine.

  Voltages up to 3.3V would be measured. Anything larger wod read the same as 3.3V. You could use a voltage divider to extend the range, but bear in mind that there is a 27K pullup resistor between the input pin and +3.3V. Analog Z probes are not supported on Duet 3 expansion and tool boards.

  @FLY fair enough, but this forum is not advertising space for closed source products our community cannot collaborate with you on. I hope you reconsider your choice about releasing the firmware source.

  @tracar said in BL-Touch and two endstop switches: G1 H1 Z-905 F400 ; home Z axis G1 Z5 F800 ; go back a few mm G1 H1 Z-905 F100 ; move slowly to Z axis endstop (second pass) G90 ; absolute positioning G92 Z0 ; set Z position to axis minimum (you may want to adjust this) G91 ; relative positioning G1 Z10 F800 ; lift Z relative to current position G90 ; absolute positioning You're using the commands to home Z using an endstop here. You should be using G30 to call for a Z probe move. Position the probe with a G1 X Y move first. See the examples here: https://duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwareCartesianPrinter#Section_Homing_Z If you have further questions, please start a new thread.

  I solve by moving with my hand the pin of the BL. I read somewhere that this is because small particles get introduced and make it difficult to move

  You might need to add some foam under the piezo to improve damping. If the wires from the piezo disks to the Universal controller are long or are routed next to heater or stepper cables you may be getting interference. Finally, with the mass of the bed providing inertia, you need to do everything you can to reduce the impulse when you start homing, even though your bed is not moving. Reduce instantaneous speed change for Z to zero, at least during probing. Reducing Z acceleration will also help. This should allow you to set the trigger threshold closer to the resting value without getting spurious triggers, improving accuracy. Idris

  @Phaedrux I actually measured my bed from the gantry and it was quite a bit off. The gantry itself is super square but the bed was slightly tilted. Also after watching some videos from TH3D I wasn’t calibrating the actual sensor properly. The bed needs to be heated when probing and the probing speed lowered to 15mm/s. The sensitivity of the sensor has to be adjusted as well with the nozzle touching the bed and the sensor approximately 2mm off of the bed. Printer is an Ender 3 pro with 1Z motor but dual axis setup and linear rails. There is a lot of weight on the X&Z axis now with the 3Dfused linear rail kit and direct drive setup so I may need an anti backlash nut. After I did the Z calibration my nozzle was slightly going into the bed.

  I think the PETG available today is generally as easy to print as PLA. Hotter temps and less cooling are the big differences. Otherwise most print settings can remain the same.

  Your application requires a very sensitive force measuring device. A load cell sensitive enough for such low amplitude of vibration can work or you could also resort to using other types of sensing techniques but I think they might be costly. You could learn more about the force sensing techniques and related concepts through here: https://tacunasystems.com/knowledge-base/an-overview-of-load-cells/

  For those of you who have a beautiful "Red, Blue, Yellow, Black, White"-cable-BLTouch: Blue goes to expansion pin 1 (+5V) Red goes to expansion pin 2 (GND) Yellow goes to expansion pin HEATERx White goes to Z_PROBE_IN Black goes to GND on ZPROBE port Maybe this can also be added to the documentation.

  Sorry everyone I wasn’t getting email notifications. I have never actually seen a ! In a command but ^ was common. The dozuki has this example M558 P9 C"^zprobe.in" H5 F100 T2000. So ^ is pull-up regardless of value and ! Is invert. Ok. So I’m betting that 3.0 let me use I1 but I have to use ! In 3.11 Thanks.
