UI remains at layer #2?

deonholt · 2 Jan 2021, 19:01

Hi all and thanks for your help.

I noticed this before.
I am busy with a print of 1089 layers high. It currently sits at 14.84mm and still says layer #2.

The problem is that the tool fan is set to start at layer #3. So it doesn't run. When I drag the slider to 100% is just goes back to 0% after a couple of seconds.

Please advise what to do. I need to fix this urgently.
Thanks.

What firmware version and DWC version?

Usually this is caused by having some Z moves in the start and end gcode which confused the DWC parser. So post a sample gcode file that has the problem.

Thank you for the prompt reply. I'm currently having the issue with the current print.
This is my specs:
Firmware Name: RepRapFirmware for Duet 2 WiFi/Ethernet
Firmware Electronics: Duet WiFi 1.02 or later
Firmware Version: 2.05.1 (2020-02-09b1)
WiFi Server Version: 1.23
Web Interface Version: 1.22.6

This is my default End gcode
G91 ; change to relative positioning
G1 E-90 F1000 ; Retract filament 90mm
G1 Z20 F500 ; lower bed 20mm from current position
G90 ; change to absolute positioning
G1 X200 Y200 ; move tool to back right
M140 S0 ; turn off heatbed
M104 S0 ; turn off temperature
M107 ; turn off fan
M84 X Y E ; disable motors

I forgot to say FW: RepRap

@deonholt can you post your config lines for the fan?

deonholt · 2 Jan 2021, 19:41

@jay_s_uk
Thanks.
; Fans
M106 P0 S0 I0 F500 H-1 ; set fan 0 value, PWM signal inversion and frequency. Thermostatic control is turned off
M106 P1 S1 I0 F500 H1 T45 ; set fan 1 value, PWM signal inversion and frequency. Thermostatic control is turned on

Can you also post the tool config section?

deonholt · 2 Jan 2021, 20:07

@jay_s_uk thanks.

; Tools
M563 P0 S"Right" D0 H1 ; define tool 0

@deonholt said in UI remains at layer #2?:

The problem is that the tool fan is set to start at layer #3. So it doesn't run. When I drag the slider to 100% is just goes back to 0% after a couple of seconds.

These are two separate faults:

The tool fan is controlled by the slicer, so the fact that it doesn't turn on is nothing to do with the display showing layer 2. As you find that it won't stay on, I suspect the slicer is resetting the fan speed to zero at intervals. But please post your entire config.g file in case it is a problem with the configuration.
The display being stuck at layer 2 is a problem I have seen before, and I think it may have been fixed in one of the 3.x releases. If you post the GCode file you are trying to print, I can simulate it and see if it has been fixed.

You should probably also update your DWC to 2.0.7 if you're going to stick with 2.05.1 for a while.

Post a sample gcode file.

@Phaedrux Thank you. This is sliced with PrusaSlicer.
Here is a link to the file.
Thank you once again. I really appreciate your help.

There are some Z moves in your start and end code, try adding ; E to them so that the DWC picks up the E and assumes it's an extrusion move and ignores them as Z moves.

In the start code: G1 Z5 F5000 ; lift nozzle 5mm and G1 Z0.28 F240

In the end code: G1 Z20 F500 ; lower bed 20mm from current position

If that doesn't work, you can try splitting out the Z moves into separate macros at calling them with M98 P
