Nozzle detach the part - Chiron Duet 2 wifi

@genioluiz7 It looks like the nozzle may be a bit low on the initial layer height, along with some extrusion issues (possibly retraction) and over-extrusion. It looks like there's something going on at the point where it changes from solid layers to infill layers.

0.1mm layers are about as low as you can go, and causes other problems, especially with overhangs and bridging. It might be worth starting with a higher layer height (eg 0.2 or 0.3) to get things working well, before reducing the layer height.

@genioluiz7 That looks okay. I think it's just tuning your Cura profile, and tuning the printer for speed, acceleration, retraction, pressure advance, etc etc... .

era l'unica cosa che potevo trovare per risolvere il problema

based on what can I understand that the problem is caused by the motors?

Does it have 2 Z motors? Is there a model number on them? Are they connected to the two Z motor outputs of the Duet 2?

Duet 2 has the two Z motor connectors wired in series. That's generally the best arrangement if the Z motors are similar to the XY motors. However, after Duet 2 was released some printer manufacturers started using low current high inductance Z motors that they intended to be connected in parallel. If your machine has that type of motor, then the series connection will reduce the maximum Z speed that can safely be used.

@dc42 this is the actual configuration:

The 2 calbes connected bottom right.

Following the pictures of the z motor

and of the x motor

They seem the same.

Let me know what you think?

@genioluiz7 if you have a multimeter then you could unplug the X and Z motors from the Duet and measure the resistances of one phase of each.

@dc42 Where have I to put the positive and the negative tips? Can you describe it more precisely?

@droftarts

I follow the Teaching Techs guide here:https://teachingtechyt.github.io/calibration.html#intro (This one not jet
https://docs.duet3d.com/en/How_to_guides/Calibration ) and the tests are all good.

Now I'm printing something bigger and this what is happening:

This is the g.code I'm using https://we.tl/t-33Er3mvoe0
What do you think? Is that a problem of speed, temperature, cooling, retraction or adhesion?

To be more coplete I post also the picture of the tests

It still looks like over extrusion to me. Try reducing the extrusion factor to 90 or 95% and see if it helps.

Furthermore I saw that this component (in the following picture) is broke. Where can I buy it?
