Will Check it out, thanks.

Firmware Version: 2.02(RTOS) (2018-12-24b1)
WiFi Server Version: 1.22
Web Interface Version: 1.22.6

Been Running for months, Have not updated anything.
I have switch to firefox recently. Did not have this problem till today.

OK, switch back to chrome just to test and it works there.
I locked a few things down in firefox for a little more security, must have changed something it doesn't like.

Something new happening.
Been trying to set maximum area to run mesh grid, but all of a sudden I am getting the following error when it tries to display the mesh grid :

A JavaScript error has occurred so the web interface has closed the connection to your board. It is recommended to reload the web interface now. If this happens again, please contact the author and share this error message:

It does save the height map in the Heightmap.csv file so I can still print.

It errors when the heightmap is displayed and closes the connection to the duet.
I took the numbers back to the original, but it does it all the time now.

PLA on cold bed. I use blue tape on aluminum. Sticks very well.

Like your tag line. I could duplicate it exactly except I have 4 rails.

I would like to setup the printer so I can hit pause if I needed to leave the printer for an extended amount of time. ie work.
Then resume with I get back, fully automated. I can do it now but have to restart some things manually.

I did not want to shut off the printer completely because of possible registration problems.

Updated attempt
Pause.g:

M83 ; relative extruder moves
G1 E-3 F3600 ; retract 3mm of filament
G91 ; relative positioning
G1 Z5 F360 ; lift Z by 5mm
G90 ; Absolute positioning
G1 X545 Y20 F6000 ; park over prime tank
G1 X545 Y0 F6000 ; finish park over prime tank

M106 P0 S0 ;Part Cooling fan Off
M106 P3 S0 ;XY Motor Cooing fans off
M106 P4 S0 ;Z Cooling fans off

T2 ;switch extruder to 0 shut off hotend.

M906 X100 Y100 Z100100:100 ; set idle motor Currents, they don't seem to be going idle during pause.
M906 E0:0:0 ; Set motor currents (mA)

---

Now the Resume :

T0 ; Active tool, turns back on hotend

;==== reset all motor currents (Because not going idle during pause?.)
M906 X1400 Y1400 Z1300:1300:1300:1300 ; set motor Currents
M906 E900:900:900 ; Set motor currents (mA)

M116 P0 ; Wait for active temps to be reached

M106 P0 S90 ;Part Cooling fan 35% (because resume not working)
M106 P3 S255 ;XY Motor Cooling fan full
M106 P4 S255 ;Z Motor Cooling fan Full

G90 ; Absolute positioning
;already over prime tank on pause.g

M83 ; relative extruder moves
G1 E7 F100 ; prime 7mm of filament

G1 E-3 F3600 ; Retract 3

G1 X535 Y0 F300 ; Wipe Nozzle

G1 R1 X0 Y0 F6000 ; go back to the last print move
G1 E3 F3600 ; UnRetract 3/prime

---

The fan settings in the resume.g are the settings I use during the print.
When I turn fans on in the resume.g the fans will come on, while completing the resume code.
But ALL fans go back off when actual resume take place.

switched to :
M106 R1 ;Resume Cooling Fan Speed

Did not change, the print cooling fan stays off.

I am trying to get the print cooling fan resume after pause.

=== Here is my current pause.g :
M83 ; relative extruder moves
G1 E-5 F3600 ; retract 5mm of filament
G91 ; relative positioning
G1 Z5 F360 ; lift Z by 5mm
G90 ; Absolute positioning
G1 X0 Y0 F6000
M106 S0 ;turn off Part Cooling Fan
T2 ;Used to set extruder to 0.

=== current resume.g :
T0 ; Active tool
M116 P0 ; Wait for active temps to be reached
M83 ; relative extruder moves
G1 E7 F3600 ; prime 7mm of filament
M106 P0 R1 ;Resume Cooling Fan Speed

Have tried may ways but the print fan will not resume.

Duet Firmware 1.21

Alright, my bad. For as much as I had looked at the connection diagram, I never really noticed the Z-probe connection. My brain seems to only see the Z End stop. Sorta working ATM.

Does not seem very linear, or is it even supposed to?
Once it get close it jumps to around 465. Move up in small increments it will jump to 535, its triggered but does not go beyond that.

I have searched for a while but cannot find how to connect the DC42 IR probe when the expansion header is used for the duex5. Anyone point me in the right direction?

Edit :
After more searching I am lead to believe I can just connect to the Z probe input. That is my current setup. With this setup I get 2 flashes on startup, and the Z-probe reading on the web interface is always hovering around 457. It never changes. When I get something close to the sensor, the red led will light but still says around 457. Acting like a trigger.

; Z-Probe
M558 P1 X0 Y0 Z1 H3 F150 T500 R0 ; Set Z probe type to unmodulated and the dive height + speeds
G31 P500 X-22 Y-1.5 Z2.5 ; Set Z probe trigger value, offset and trigger height
M557 X15:570 Y15:570 S100 ; Define mesh grid

(sorry, cannot edit category, should be IR)

Thanks
Ed.
