Can't start second print without power cycling (SKR 1.4 Marlin)
February 05, 2021 04:34AM
Hi everyone,

Just registered because I'm having a problem with My Ender 3.

I upgraded the board to an SKR 1.4 a while ago and installed Marlin 2.0. From the beginning I've had the issue that my prints would finish perfectly, the display would go back to it's idle state, but when selecting a new print from the SD card it simply wouldn't do anything.
Power cycling the Ender would solve this issue.
It's not a very big deal, but I started using Octoprint this week and decided to try a find a solution to this problem as well.

I've searched the internet but haven't been able to find anything describing my issue.

The end G-code in cura looks like this:
; Ender 3 Custom End G-code
G4 ; Wait
M220 S100 ; Reset Speed factor override percentage to default (100%)
M221 S100 ; Reset Extrude factor override percentage to default (100%)
G91 ; Set coordinates to relative
G1 F1800 E-3 ; Retract filament 3 mm to prevent oozing
G1 F3000 Z20 ; Move Z Axis up 20 mm to allow filament ooze freely
G90 ; Set coordinates to absolute
G1 X0 Y{machine_depth} F1000 ; Move Heat Bed to the front for easy print removal
M106 S0 ; Turn off cooling fan
M104 S0 ; Turn off extruder
M140 S0 ; Turn off bed
M107 ; Turn off Fan
M84 ; Disable stepper motors
M117 That's All Folks!
; End of custom end GCode

Please let me know if you have any ideas on how to solve this.
All help much appreciated!

When you installed this new Version of Marlin 2.x.x did you restore defaults.

Using Marlin 2.x.x
Click the encoder > select Configuration > select Reset Defaults.
Save Results.

Hi Roberts-Cliff,
thanks for your reply!
Do you mean on the printer? I have a 'restore failsafe' option in the configuration menu, but no 'Reset Defaults'.

On the LCD Yes.

Normally I send a M502 Factory Reset followed by a M500 Save Settings using terminal mode.

Exactly same issue here. After printing, the only solution to print again is to reset sad smiley
