HAHA guys i found the problem i can't believe: I used the wrong motor directions so nothing worked logical, minus were plus and plus were minus Hääää??? oh my god now it works like it should.

bowden length is about 700mm and i have done the calibration to find the value. With this value i get good results

yes checked that. Here is also a video with cover (second bearing) mounted.

metal gears still slipping

Commando Back, talked with bondtech Support and they told me it is designed for using with Filament loaded. Then they doesn't Slip. Reassemled and If i Turn the White Gear fast Back and forth by hand with Filament loaded There ist absolutely No Bad Sound. So i will try it again. If it is Not better i will do a Print without bondtech Extruder to Gear only Extruder stepper

Because of this abnormal and unexplainable thing i could not sleep anymore. I deassembled my effector and found the reason: when i put the heatsink back into the effector hole i not watched careful enough to my hot end fan wires. Therefore i clamped the black wire between the sink and the effector plate. OMG

Because of the elasticity of the isolation i got a different trigger height. Now i get my old trigger height. Reason found and explained. Now i can sleep like a baby again

@alankilian ok i will remove it. Thank you very much

@alankilian 24V Input to the VIN terminal

Hi there,

i bought a used duet 2 wifi on eBay installed it and used it for some weeks without problems. Today i noticed that there are jumpers on both EXT 5V EN AND INT 5V EN. The documentation says only jumper one at the same time..

Now my question is what will happen if both are jumperd?

Thank you

@dc42 that's exactly what i assumed. So i not checked the height and just started a print. The nozzle scratched the bed
Maybe the full metal heatbreak is more yielding then the ptfe lined one.. That's the only part i switched with the nozzle. But i also can't imagine that this will make such a big difference

Hi there,

I am using a smart effector. Yesterday i had to change my nozzle. I thought: cool no problem because i have the smart effector which probes by nozzle contact... So i will have no problems and no fiddling after the nozzle change. But after the change i noticed that the trigger height changed. Can someone explain why? I can't imagine because the nozzle is the probe... Or does the nut on the heatsink has an influence here?

Thank you guys

no i use the stock smart effector values. I think you forgot the macro or i am blind?

Hi there,

i upgraded my Anycubic Predator (delta printer) with the duet smart effector. I noticed when i calibrate the trigger height the first probe is often much more off than the following probes: (probing at the same XY location!)

As i am using 0.9° steppers the difference should only be 0.006 mm. Whats the problem here?

thank you

@engikeneer thank you that sounds great. I am from germany

@engikeneer ahhh thank you i saw the Duet 3 Mini 5+ has normal connectors except one for the extruder heater. Perfect but sadly not available
