Start gcode for Cura 15.4.4


Recommended Posts

Posted (edited) · Start gcode for Cura 15.4.4

I am printing with a Lulzbot Mini printer that now has Cura 15.4.4 recently installed.

Cura 15 is an unfamiliar change from the earlier versions of Cura that allowed me to manipulate the print head position and bed/head temperatures with a simple interface. So I started to tinker with the gcode in the newer version to try and get what I wanted from the driver.

I'm now running this start gcode:

;Sliced at: {day} {date} {time}

;Basic settings: Layer height: {layer_height} Walls: {wall_thickness} Fill: {fill_density}

;Print time: {print_time}

;Filament used: {filament_amount}m {filament_weight}g

;Filament cost: {filament_cost}

;M190 S{print_bed_temperature} ;Uncomment to add your own bed temperature line

;M109 S{print_temperature} ;Uncomment to add your own temperature line

G21 ;metric values

G90 ;absolute positioning

M82 ;set extruder to absolute mode

M107 ;start with the fan off

M109 S180 B210 F1;activate auto temp min 180 max 210 scaling factor 1 (for PLA)

G28; Home Axis

G29; Z-Probe the bed (requires Z-Probe!)

G1 Z5.0 F9000 ;move the head 5mm up for CYA clearance

G92 E0 ;zero the extruded length

M117 Cleaning...;Put Cleaning message on screen

G1 X100 Y0 F4000 ; move half way along the front edge

G1 Z1 ; move nozzle close to bed

M109 S200 ; heat nozzle to 200 degC and wait until reached

G4 P10000 ; wait 10 seconds for nozzle length to stabilize

G1 E10 ; extrude 10 mm of filament

G1 z15 F12000 E5 ; move 15 mm up, fast, while extruding 5mm

G92 E0 ; reset extruder

M117 Printing...;Put printing message on LCD screen

It begins printing the object 5-10 millimeters off of the print bed, which I think is attributed to the fact that the bed leveling washers in the corners of the bed are approximately that same height (5-10mm) off of the bed. It seems not to recognize that. What is the ideal start gcode for me to run on a Lulzbot Mini with Cura 15.4.4?

    I think your solution, nallath, will work best. For whatever reason I was only perusing the normal versions of Cura, as opposed to the Lulzbot-specific ones.

    This does keep me dumber to the functioning of gcode, but it will be easiest.

    Didier, I think I'll play with some of those commands as well, in order to learn.

    Thank you both!

      • UltiMaker Cura 5.3 stable released
        In this stable release, Cura 5.3 achieves yet another huge leap forward in 3D printing thanks to material interlocking! As well as introducing an expanded recommended print settings menu and lots of print quality improvements. Not to mention, a whole bunch of new printer profiles for non-UltiMaker printers!

      • Here it is. The new UltiMaker S7
        The UltiMaker S7 is built on the success of the UltiMaker S5 and its design decisions were heavily based on feedback from customers.
        So what’s new?
        The obvious change is the S7’s height. It now includes an integrated Air Manager. This filters the exhaust air of every print and also improves build temperature stability. To further enclose the build chamber the S7 only has one magnetically latched door.
        The build stack has also been completely redesigned. A PEI-coated flexible steel build plate makes a big difference to productivity. Not only do you not need tools to pop a printed part off. But we also don’t recommend using or adhesion structures for UltiMaker materials (except PC, because...it’s PC). Along with that, 4 pins and 25 magnets make it easy to replace the flex plate perfectly – even with one hand.
        The re-engineered print head has an inductive sensor which reduces noise when probing the build plate. This effectively makes it much harder to not achieve a perfect first layer, improving overall print success. We also reversed the front fan direction (fewer plastic hairs, less maintenance), made the print core door magnets stronger, and add a sensor that helps avoid flooding.

        The UltiMaker S7 also includes quality of life improvements:
        Reliable bed tilt compensation (no more thumbscrews) 2.4 and 5 GHz Wi-Fi A 1080p camera (mounted higher for a better view) Compatibility with 280+ Marketplace materials Compatibility with S5 project files (no reslicing needed) And a whole lot more  
        Curious to see the S7 in action?
        We’re hosting a free tech demo on February 7.
        It will be live and you can ask any questions to our CTO, Miguel Calvo.

      • UltiMaker Cura Alpha 🎄 Tree Support Spotlight 🎄
        Are you a fan of tree support, but dislike the removal process and the amount of filament it uses? Then we would like to invite you to try this special release of UltiMaker Cura. Brought to you by our special community contributor @thomasrahm
        We generated a special version of Cura 5.2 called 5.3.0 Alpha + Xmas. The only changes we introduced compared to UltiMaker Cura 5.2.1 are those which are needed for the new supports. So keep in mind, this is not a sneak peek for Cura 5.3 (there are some really cool new features coming up) but a spotlight release highlighting this new version of tree supports.
