  @felt342 It seams they have modified the newer ones. The picture of the set screw isn't included in the manual anymore. I have also found a video for the pin replacement on youtube . So I think yes it is locked.

  That's a bug, I have already reported. Let it set to the e1heat. You have to adjust that later on in the config.g The probe section then should look like that ; Z-Probe M558 P9 C"zprobe.in" H5 F120 T3000 ; BLTouch connected to Z probe IN pin, free up MOD pin M950 S0 C"zprobe.mod" ; servo/gpio 0 is Z probe MOD pin Configuration for Ender3 config.json

  @Danal I appreciate the information, thank you! That last question is kind of hard to explain, especially without pictures. The hotend accepts 5 bowden style connections, since these connections are under the effector I need to make sure that the distance from the connectors to the underside of the effector is far enough that I can physically connect the bowden tubes and keep the filament from binding due to an extreme bend radius. I also hope that there is enough room to install at least two Zesty Nimbles. I spoke to Duet, I'll be doing a mock up to see if it will work and report my findings here. Thanks again!

  Second thermocouple daughterboard not recognized

  @atmark Can you check which version of the thermocouple daughter boards you have? The older boards are MAX31855-based, the newer ones are MAX31856-based. This will change the M305 assignment. As it says https://duet3d.dozuki.com/Wiki/Connecting_thermocouples#Section_Duet_2_WiFi_Ethernet_and_Maestro If your daughter board uses MAX31855 chips then the terminal blocks labelled 1 and 2 on the lower daughter board will be temperature measurement channels 100 and 101 respectively. If you stack two daughter boards, the terminal blocks on the upper board will be channels 102 and 103. If your daughter board has two LEDs labelled FAULT then it uses MAX31856 chips. In this case the terminal blocks labelled 1 and 2 on the lower daughter board will be temperature measurement channels 150 and 151 respectively. If you stack two daughter boards, the terminal blocks on the upper board will be channels 152 and 153. If you've got newer boards, and your config.g should be set up as: M305 P1 X150 M305 P2 X151 M305 P3 X152 Though I did test this (I only have a PT100 daughterboard and a newer thermocouple board stacked on top), using X101 did report 2000C temps. So I'm not quite sure what's going on with your setup. Lastly, make sure there is a comment mark ; before "Super Volcano 80W 24V" in your config.g. This should be ignored, but just in case it's causing problems, put it in. Ian

  @chrishamm I went the scale factor route, and that works quite well. I ended up at 2.

  Before upgrading to Duet 3 I had a raspberry pi 3 running motioneyeos which is rock solid stable. On my new Duet 3 setup I have a Raspberry pi 4 running the Duet software on top of Raspbian Buster (not the DuetPi.img). This is so that I can run the full blown Raspbian Buster and give me 100% flexibility. I have customised Buster i.e removed all games and unwanted programs and utilities to make it look more professional. I have a touchscreen connected to RPI4 but also have the option to use Bluetooth mouse and keyboard if I want to. I have created a script and a taskbar Icon that automates the shutdown of both the RPI's. This setup is ideal for me and even though the RPI4 is likely capable of streaming video to the DWC, it is relieved of the resources.

  Glad it's working out now. I should have taken a closer look at your homing files sooner. That was definitely part of the confusion.

  To aid the setting up of the Precision Piezo(s), I replaced the single turn potentiometer, with a multi turn type. This gives far greater control of sweet-spot settings, and ensure I get consistent repeatable reading across a 300x300 mm bed.

  @Veti Thank you for the tip!!! Will do this in the future to try and solve it myself. I started from the BLV-Cube pre configured files. For some reason the x & y endstop work without the suggested modification. (will modify and test this anyway) Also thank you for pointing out to the heater & fan setting. Those are the next things I need to find out if it works as intended.

  Found out my problem. I noticed one side of my printer was always sagging towards end of print, ran motor unlock and i could rotate left z and feel steps, but right z just spun - i guess my right z motor had failed. Replaced my right z motor, and now bltouch is happy and i don't have to run g29 between each print... kind of surprised i got the quality i did with that motor having been bad or faulty for so long... but, i'm back in business... no more crazy drift, nice level bed and great prints again. took the time to move to reprap3 firmware and enjoy it too!

  I don't use any special cable, the typical servo cable. and does not pass near any 230V cable. It is located about 30cm from the Duet3D

  @Deltasquare said in Did I kill my DuetWiFi?: So I have a new board now. Just to make sure this time: If I run a 24V System, I can only set the voltage to 12V on the DueX. By "I can only set the voltage to 12V on the DueX", do you mean you can set the Fan voltage to 12V on the DueX but not on the Duet? If so, that is correct. For this purpose we have the jumper on the Duex. If I set it I can power Fans as well as LEDs from Duex Correct, if you connect the LEDs to spare fan outputs. however, the Duex does not act as a constant power source for the LEDs. Do you mean that you want some "Always-on" LEDs? The most recent DueX5 revision has a 12V always-on output (when the 12V Enable jumper is in place). For other DueX5 revisions, with the fan voltage selection jumper set to 12V you can connect a 12V always-on fan or LED between the VFAN pin of any fan output and the ground VIN connection.

  @zecchi yes and its not prone to interference like the bltouch. it is not as compact
