You might need to increase the recovery time (R parameter) in the M558 command if the flying extruder tends to bounce around after a travel move, but other than that I can't see why it wouldn't work. A steady upwards pull will be ignored by the on board electronics and firmware. What it's looking for is a sudden change in the forces on the PCB.

Thank you - sorry to waste your time
calibration worked well, giving before 0.030 after 0.019 for 10 points 6 factors
the mesh map looks ok, with maximum deviations -0.079/0.082, mean error 0.003 and RMS error 0.036
Wonderful piece of kit and fantastic support

I was thinking that given the large nut under the adaptor is hard to access with the adaptor in place, for example to tighten the hotend if it gets loose, maybe the adaptor could incorporate a nut trap to fit the M12? nut provided by Duet. This way the nut would be captive, the heatsink could be screwed tightly into it easily, and then the hotend position set by tightening the heatbreak into the nozzle at the desired position.

Right, I forgot that e3d released the original Injection molding cad file, so I'll use that. Thanks!

What would be the optimal cable to use to make a wiring harness?
I think I'll try to make it myself 🙂

yes we caught up on shipping today!

David how do I mark it as solved rather than just put Solved in the title

Yes if you want to be able to program the sensitivity.

Ok I must have overlooked the crimp as I though I had checked them all, seems it was a poor crimp on the 3.3 line, all fixed and working perfect

Wish there was a like button on this forum

I have created a new forum to discuss the smart effector here https://www.duet3d.com/forum/viewforum.php?id=13 so I will now close this thread.
