Cura 5.7 bugs (start GCode)

[lanman31337 0]

Cura 5.6 has no issues. Installed Cura 5.7, and when I go to print, instead of heating up the bed and nozzle and then once warmed up it homes and starts printing, it'll home, goto 0/0 with the nozzle against the build plate, and then heat up. I thought that would cause more issues with blobbing. This is the Ender 3 V3 SE profile.

You should be more worried about it melting through the top layer of the build plate and exposing the metal sheet underneath (it's happened to me).

 

This is why I use my own custom definition. Still, try changing the startup gcode to:

M220 S100 ;Reset Feedrate
M221 S100 ;Reset Flowrate

G28 ;Home

M420 S1; Use saved mesh leveling data

G92 E0 ;Reset Extruder
G1 Z5 F3000 ;Move nozzle up
G1 X0 Y20 F5000.0 ;Move to start position
M190 S{material_bed_temperature_layer_0 - 20} ; Start heating bed
M104 S{material_print_temperature_layer_0} ; Start heating hot end
M190 S{material_bed_temperature_layer_0} ; Set bed temperature and wait
M109 S{material_print_temperature_layer_0} ; Set hotend temperature and wait
G0 Z0.28 ; Lower nozzle
G1 X0 Y100.0 Z0.28 F1500.0 E15 ;Draw the first line
G1 X0.4 Y100.0 Z0.28 F5000.0 ;Move to side a little
G1 X0.4 Y20 Z0.28 F1500.0 E30 ;Draw the second line
G92 E0 ;Reset Extruder
G1 E-1.0000 F1800 ;Retract a bit
G1 Z2.0 F3000 ;Move Z Axis up
G1 E0.0000 F1800 

That'll keep the nozzle at 5mm off the bed until it's hot, and instead heating the bed all the way THEN heating the hot end because I find the hot end heats up quicker than the bed, it waits until the bed has warmed to 20° below its final temperature, tells the hot end to start heating up, then waits for both the bed and hot end to heat up.

 

Let's just say that whoever is maintaining the definition in Cura... I'm not a fan of their work.
