  @arhi said in How to setup the Bigtreetech smart filament sensor?: But in both direction one need to come first they should never turn on in the same time not a problem as long as its different in the other direction. (ofc. if they turn on and off at the same time in one direction it'll make it tricky to distinguish the other direction)

  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.

  Thanks Guyaros, I was able to do the same conversion on my newer FFCP. Installed the Hemera and Duet Wifi and your configs worked very well. I ended up adding a BLTouch as well which has made homing the Z-axis more accurate plus adds all the benefits of bed levelling and mesh. I remixed your Hemera mount to add a mount for the BLTouch and a 5cm post to tie the wiring to. Seems to work very well. I’ll post the remix on Thingiverse. Thanks so much for your efforts. Much appreciated!

  @jens55 yeah it's 34" L x 30"w x 30" T, Double walled Cardboard with inner surfaces tinfoil lined. The top definitely leaks, I need to add some foam adhesive strips to fill gaps. This is my design, ABS plastic fittings hold it together Honestly, I don't need DWC control just want something with temp monitoring and shutoff. For obvious reasons. My Amazon special space ceramic heater must have a temp sensor bc I only runs for like 5mins in there before it shuts off, which is nice but it won't stay running long enough

  This project is currently on hold. I had to go back to work on other things. I have not yet ordered a new revision of the hardware as I need to make sure that the Attiny85 is actually capable of driving the servo and steppers in a robust manner. I worry that the processing rate of the Attiny is not fast enough for the servo motor. Tuning is very difficult. I have some control over the servo in a closed loop, but am worried about lost steps, overshoot and oscillation.

  Forgot one more thing, the top part, make sure you drill those holes so that screws can slide through them easily. The screws need to be biting only the bottom part, they need to be able to slide easily through the top part. Ideally, you should use screws that are threaded only at the bottom

  @Phaedrux said in BLTouch very occasionally not deploying: Also, for the future, it's a good idea to use M913 to drop the motor current during homing just in case there is a crash. That way the motors will stall before causing much damage. Turns out I'm already doing that, I just never added a Z parameter (sensorless homing on X/Y). It's also a good idea to add a alarm release and retract command to the start of homeall and to the end of config.g just to get the BLTouch ready in case it is not. Ask me how I know. No need to ask, I should know myself. In fact, I had assumed I was already doing that, but I was not.

  @Phaedrux got it. I will look for Both in Cura. No big issue except the speed is shaking everything. Still prints well I am guessing due to the box frame of the 5+ but I think I can slow it down a bit. The mesh bed I have set 0-330 for x and y and set it at 30mm increments this past run. Was using 60mm before. It probes a lot and takes quite some time to complete at that rate. But it still had issues printing in a certain area.

  Not directly. Only Duet3 hardware supports direct drive of dotstar or neopixel. With Duet 2, you'd have to drive a pin that switched a controller that, in turn, drove the LEDs.

  Never mind. I just found that polarity in the control wires is irrelevant. Heater works now.

  Hello guys again, i just came back after some further testing of this leveling feature. I thought maybe BLtouch was giving wrong signals. I have replaced probe with E3D smart IR probe. I was able to mount it much closer to nozzle and probe whole bed a little better (offsets 6.2 mm x 17 mm). Also I have anti-backlash nut on Z axis. I was still using the function to probe every single points at least 2 times and with accuracy of 0.01 mm. Smart IR probes much more reliably and gives better repeatability. Also I have been using glass fiber bed (since glass one had strong bowl effect). Bed mesh looks very close to how the actual bed looks like. Attaching bed mesh screenshot. Bed mesh appears to be working much better than it was before, however. Z probe calibrated at Z=0 (touching bed). Tried print object over whole bed and nozzle is way too high everywhere. Lines are not being connected, but it looks like bed mesh is working completely fine and compensating everywhere. Lines were everywhere looking the same width. Just why nozzle was still too high? What I have noticed, that second layer goes perfect. But anyway first layer does not adhere with bed good enough to hold through the print and I still get not nice surface finish.

  Most heaters do fine with slower control loops and zero-crossing switching; lighting and motor control will benefit from phase angle control however.

  @CookieHunter said in BLTouch create weird bumps in mesh: G31 X-21 Y-54 Z1.023 P25 I’d say it was because of the large Y offset of the probe and small rocking of the X carriage is being amplified by the offset. Try to mount the probe closer to the nozzle, preferably in line in X, so the Y offset is 0. Ian

  @Phaedrux I tried it one more time and it works, sort of. Using a z offset of -1.70 it stops quite a ways from the head. I will have to re-calibrate.

  I also did the same, documented the process: https://forum.duet3d.com/topic/14485/rrf3-bltouch-setup?_=1583394715553 I'm now using a duex5 though so no longer use that setup.
