Ultimaker Cura settings for Taz6?

#1

I trying to setup slicing via the Ultimaker Cura and copied the start and end codes from the examples on the lulzbot website. When the printer starts the process of press the buttton, wiping, touching the four corners the temp shows 200. Normally (using Cura LE) it is lower (maybe 170 or less?) I’m nor sure why the temp is so high during the bed leveling. I selected the generic PLA as the material. Here is my start code:

;This G-Code has been generated specifically for the LulzBot TAZ 6 with standard extruder
M75 ; start GLCD timer
G26 ; clear potential ‘probe fail’ condition
G21 ; set units to Millimetres
M107 ; disable fans
M420 S0 ; disable previous leveling matrix
G90 ; absolute positioning
M82 ; set extruder to absolute mode
G92 E0 ; set extruder position to 0
M140 S{60} ; start bed heating up
G28 XY ; home X and Y
G1 X-19 Y258 F1000 ; move to safe homing position
M109 R{170} ; soften filament before homing Z
G28 Z ; home Z
G1 E-30 F100 ; retract filament
M109 R{170} ; wait for extruder to reach wiping temp
G1 X-15 Y100 F3000 ; move above wiper pad
G1 Z1 ; push nozzle into wiper
G1 X-17 Y95 F1000 ; slow wipe
G1 X-17 Y90 F1000 ; slow wipe
G1 X-17 Y85 F1000 ; slow wipe
G1 X-15 Y90 F1000 ; slow wipe
G1 X-17 Y80 F1000 ; slow wipe
G1 X-15 Y95 F1000 ; slow wipe
G1 X-17 Y75 F2000 ; fast wipe
G1 X-15 Y65 F2000 ; fast wipe
G1 X-17 Y70 F2000 ; fast wipe
G1 X-15 Y60 F2000 ; fast wipe
G1 X-17 Y55 F2000 ; fast wipe
G1 X-15 Y50 F2000 ; fast wipe
G1 X-17 Y40 F2000 ; fast wipe

G1 X-15 Y25 Z1.5 F1000 ; slow wipe
G1 X-17 Y23 F1000 ; slow wipe
G1 Z10 ; raise extruder
M109 R{210} ; wait for extruder to reach probe temp
G1 X-9 Y-9 ; move above first probe point
M204 S100 ; set probing acceleration
G29 ; start auto-leveling sequence
M420 S1 ; enable leveling matrix
M425 Z ; use measured Z backlash for compensation
M425 Z F0 ; turn off measured Z backlash compensation. (if activated in the quality settings, this command will automatically be ignored)
M204 S500 ; restore standard acceleration
G1 X0 Y0 Z15 F5000 ; move up off last probe point
G4 S1 ; pause
M400 ; wait for moves to finish
M117 Heating… ; progress indicator message on LCD
M109 R{210} ; wait for extruder to reach printing temp
M190 S{60} ; wait for bed to reach printing temp
G1 Z2 E0 F75 ; prime tiny bit of filament into the nozzle

You probably need to eliminate the curly braces from your start g-code. Curly braces should only be used to surround the names of variables. But the values in your code are actual values… not variables.

In Cura, the curly braces { } represent variables. They support only specific variable names and not the same variable names as Cura LulzBot Edition. I’ve searched to try to find the names of variables they use but haven’t been able to find a reference to them (if anyone knows of one… please let me know).

Anyway…

You’ve got lines that read (for example)

M109 R{170}; wait for extruder to reach wiping temp

That’s just an example row… but what that needs to say is just
M109 R170; wait for extruder… blah blah blah

Note the curly braces aren’t used (because ‘170’ is the actual value you want to use … not the name of a variable.)

Hopefully that helps.

Thanks! I program so I should have realized that.
