Restarting print job after cancelling

Recommended Posts

I'm using Cura 3.1 (final, not beta) and saving gcode to micro SD card for an MP Select Mini v2.  When I cancel my print job and then restart it, the print head on my printer travels all the way to right and then starts making a ratcheting sound like it wants to keep going further to the right, past the limits of the arm.  I'm wondering if it's something in my gcode, because I have tried reducing the size of the print bed in Cura to 118mm (from 120mm) but it still does it.  Not sure if this is a Cura issue or not, but the gcode worked in version 15 of Cura.

 

Here's my gcode settings that I got from the MP Mini wiki:

Start GCode:

G28 ;home all axes
G1 Z0.2 F1200 ;raise nozzle
G92 E0 ;reset extrusion distance
G1 X100 Y0 E12 F600 ;purge nozzle
G92 E0 ;reset extrusion distance

 

End GCode: 

M104 S0 ; turn off hotend/extruder heater
M140 S0 ; turn off bed heater
G91 ; set to relative positioning
G1 E-2 F300 ; retract the filament a bit before lifting the nozzle to release some of the pressure
G1 Z1 ; raise Z 1mm from current position
G1 E-2 F300 ; retract filament even more
G90 ; set to absolute positioning
G1 X20 ; move X axis close to tower but hopefully far enough to keep the fan from rattling
G1 Y120 ; move bed forward for easier part removal
M84 ; disable motors
G4 S360 ; keep fan running for 360 seconds to cool hotend and allow the fan to be turned off - adjust to your needs
M107 ; turn off fan. Don't use M106 S1. Some say M107 doesn't work for them but if the hotend is below 70 degrees it should work

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
