I did the autotune but I did not solve the problem … I also narrowed the thread thinking it was the problem. if I connect the pt100 directly to the board I do not have this problem ...

what are the shielded cables you used? because the temperature is not constant but varies eg between 189 and 194 when imposed 190 degrees. will it be because the cables are not shielded?

I solved. the cable was too double. sorry for the post as it is eliminated?

hello I'm having problems with the pt100 sensor. if I connect the sensor directly to the MAX31865-based daughter boards I have no problems and I can have the right temperature the problem is when the wires are firmly in order to arrive with the sensor to the cartridge, it no longer detects the temperature and marks 2000 degrees. how can I fix it? do I need a special cable? thanks

it turned into home, now i have to adjust z axis. when it's in home position i can't move the axis.

hi what are the commands to move the z axis over the 0? thank you

I'm sorry that I have to put in value g31 z ??

It has been set that value
[c] G31 Z-0.02 P50
[/c]

p50 for a npn probe is correct? When I probe with G30 S-1 it works well … with G32 instead of the dish does not rise up to the nozzle ... as I installed firmware 1.18 beta 1 could be the problem?

hi, I have a problem with g32 after running it I will lower the level of 5mm and of the press away from the nozzle … how can I fix this? I not really understand where I'm wrong

I solved it by placing more double wires, now works fine. I only have a problem when I hand printing the extruder is too far from the plate.

after running the g30 it goes down and stays away from the extruder and when printing the non-return to zero … how do I fix?

does anyone have any idea what could be?

yes…

hi I just plugged the PT100 sensor but when I go to extrude me error:
Error: Temperature reading fault on heater 1: sensor hardware error

How can I fix the problem? thanks

Thank you very much… now it works maybe I accidentally pressed erase ... to make the sensor was enough to put the aluminium plan to grounded ... which means?

I managed to run the npn sensor … the problem is that after the homing the duet has disconnected from the Internet and now you do not connect via usb even more I unplugged all the outlets but not goes ... what could this happen ?? It worked great before

is the broken sensor or I do something wrong?

I tried to change the sensitivity but always remains a link light. The positive I take it directly by a 24v is wrong? the negative and the signal on the pins instead dell'e0 stop … could be the sensor ?? thank you

I entered the command M558 P4 X0 Y0 Z1 I1 in the config file but the LED is always on … when I give the g30 s-1 command me error "Z probe Already triggered at the start of probing move" something wrong ?? thank you so much
p.s. i'm used the but85 diode for the signal probe...

I connected npn but the LED on the sensor is always on … in the videos I've seen on youtube, the LED should light up only when you approach the plan?

hi, thanks I will test all the values that you told me. I bought a npn sensor for auto-leveling and reading the wiki is written using a diode .. what type of diode does it take? thank you

NPN output normally-open inductive or capacitive sensor
Connect its output wire to the cathode of a diode, and the anode of the diode to the E0 STP pin. Connect the sensor ground wire to a ground pin on the Duet, and the sensor's + power wire to a suitable voltage (typically to VIN because these sensors usually need between 6 and 30V power).

The diode should preferably be a small-signal Schottky diode such as BAT43 or BAT85, but a small signal silicon diode such as 1N4148 works for some people.

Select mode 4 in the M558 command. If using firmware 1.15e or earlier, include M574 E0 S0 in config.g to select active low logic level for the Z probe. If using firmware 1.16 or later, include parameter I1 in the M558 command instead.
