What is the layer height that you are printing with.. it can so happen that the extruder is pushing more that what is coming out and pressure is building up in the extruder.
Also check your layer change and retraction settings in the slicer. probably layer height change is taking a long time.
you can also read through the gcode that is generated and check for unwanted codes or change in feedrate.
I read a few posts that talk about peltier heating OR cooling and also found one post that talks about both together but I believe it is still incomplete.
i know i need to use a relay to switch on and OFF the peltier and a DPDT/H-bridge to switch polarity on the peltier.
But on the firmware side, i am new with 0% programming knowledge so i need some help there. I read on one post, where David said its not in Heat.cpp but in pid.cpp
https://forum.duet3d.com/topic/5057/reverse-polarity-of-heater-peltier-heating-cooling/31
But what next.???
i am just making sure i don't fry the board by doing something wrong
my doubt is whether this can be done;
and if i wanted to connect two probes can one more be connected in the E0 endstop STP pin for the U axis?
Then i tried using theProbe for the U axis and i made this tiny change in the config.g file;
; Endstops
M574 X1 Y1 Z1 S0 ; Set active low and disabled endstops
M574 U1 S2
And that too worked fine
Ok so i did connect a Zprobe and got it working. I made the following changes and it worked for the NPN inductive sensor that I scavenged.
I made the following wiring. I used the IN4007 because i dint have anything else on me.
The following config changes were done;
**; Endstops
M574 X1 Y1 U1 S0 ; Set active low and disabled endstops
M574 Z1 S2
; Z-Probe
M558 P1 I1 H5 F120 T6000
M557 X25:0 Y25:0 S20 ; Define mesh grid**
and it worked fine.
ok then im safe... my hardware says Duet2 V1.04... yippie
mine says;
M115
FIRMWARE_NAME: RepRapFirmware for Duet 2 WiFi/Ethernet FIRMWARE_VERSION: 2.0(RTOS) ELECTRONICS: Duet WiFi 1.02 or later + DueX5 FIRMWARE_DATE: 2018-06-05b3
so I guess it's not compatible!
so even a capacitive probe, working on 12V will not harm the Duet if the signal pin of probe is connected to any endstop STP pin.
what about on the hardware side... where can i put the additional probe pins?
yes i too feel it is a hardware issue.
yes i downloaded the one from the link David sent in his replies.
@dc42 since the extruders are independent, and z axis and x axis will also be independent. we will need two probes right?!
@Veti i had the same 2.03.
i was using this in my printer for3 months now suddenly, the wifi module dint flash its blue LED so i thought its time for an update and tried updating the DuetWiFiServer.bin. So i am not sure if its a hardware or firmware issue.
I followed the steps and this is the same message that came up;

@dc42 what about putting two probes for each Z?? is that possible??
Have you guys checked out the ZideX 3D printer.
Its awesome.
I thought i would build a similar one but with two probes to home each independent Z axis.
This calls for two probe pins that I believe the DuetWifi doesn't have. Does anyone know a hack around it? I am thinking of two inductive sensors for the two Z axis.
yes i too got it working on separate USB.. works well... i was wondering why i am not getting 5V at the pin next to the PS-ON pin.
