@sebkritikel quello che ho corretto io funziona bene
ho provato e l'estrusore funziona bene

Buona notte a tutti

@sebkritikel thank you so much my friend

no problem, I don't wear it and I'm happy like this

@Phaedrux

ok, I'll call you hawkeye, correct and take the test again

@Phaedrux ok I will try in the meantime I disassembled the x axis turned the bearings
"just to give it a try while I was waiting for some advice from you" and now I've reassembled it and put it back to making a cold mesh to see if anything has changed, then I'll try to print to see if the mesh works or not, tomorrow I will post the results with and without mesh, for the moment thanks @Phaedrux.

@fcwilt ok grazie

@arnold_r_clark said in proximity sensor PNP:

Connect the sensor output wire to one end of a resistor (call this R1), and connect one end of another resistor (call this R2) to GND on the Z-probe connector. Connect the free ends of R1 and R2 together and to the IN pin of the Z-probe connector.

that is, as in the picture?

@fcwilt Forgive me you are right I have described the problem without giving you information.
My card is a duet 2 wifi v1.04 with firmware 3.4.1
the printer is a corexy tronxy
the voltage is 24v except for the bed which is 220v
yes I used them a couple of years ago but I don't remember anything anymore
the problem as I described at the beginning of the post is that the aluminum base of the printer is not made for an inductive sensor, so having the PNP sensor capicitivo and I wanted to exploit it

I accidentally got a PNP capacitive adjustable proximity sensor instead of the usual NPN.
Having mounted a magnetic bed about 4mm high and a 6mm heated plate of non-deformable aluminum at high temperatures milled on both sides and already having an inductive sensor NPN XY-08n "Tronxy" which works quite well "when it comes to normal aluminum or steel "and connected on the fan connector always active as 24v power supply and signal on Z_PROBE_IN, but it measures too little 0.8mm and forces me to remain dangerously low in the printing phase, I had already used the PNP sensor in the past with excellent results, now what I ask you is there a figure that shows the functioning electrical connection of the PNP sensor?, I looked at some post in particular the one who realized after burning the card that patience is the virtue of the strong , can you help me to have a diagram of how it should be connected without damage?

even the temperatures will have to lower by 5 degrees, petg mold at 230 degrees the print bed 75 degrees

@Phaedrux

probable, in fact I put my hand back to the configuration and I lowered the jerk from 1000 to 600, then once another piece is printed if I get improvements I post a photo

and it never happened to me, at least until recently

@Stephen6309

The plate on top helps prevent filament from falling into the hole. I knew this, as far as I know with care there are tricks to avoid the plate, maybe I have the wrong settings I just have to understand where I was wrong, but to make you understand better I designed this to make you understand ..

The piece I did it with fusion 360

@Phaedrux Good afternoon, here are the files you requested!
