Getting A Good Print What do you control?
• A Valid Model
• A Working Machine
• Calibration

Calibration Getting the First Layer Right
• Absolutely the most important part of your print
• 99% of all problems happen on the first layer
• If the first layer is good the rest probably will be

What to do? Level The Bed
• Nothing is more important
• Nothing will help if this is not right
• More tips - after we level…

How to Measure Level Use a Drop Indicator
Advantages
• Very accurate
Disadvantages
• May be un-mountable
• Cumbersome to use

How to Measure Level The paper method
Advantages
• Works on all printers
Disadvantages
• What is correct paper
• What is correct preasure
![Page 6: Troubleshooting common challenges with 3d printers](https://reader034.vdocuments.net/reader034/viewer/2022051513/547c64a8b4af9fc9158b5116/html5/thumbnails/6.jpg)
How to Measure Level Just eyeball it!
Advantages
• We all have the equipment
• Easy to use
Disadvantages
• Some printers not visible
• Takes some finesse

X-Axis Leveling If 2 lead screws (x-axis)
• Move carriage to left
• Move extruder to bed
• Move carriage to right
• Adjust screws to fix height
• Repeat until level on x

Bed Plate Leveling With adjustable sprung bed
• Loosen back right screw
• Move extruder to corners
• Adjust other 3 screws
• Repeat until level
• Tighten back right o Just touching plate only
![Page 9: Troubleshooting common challenges with 3d printers](https://reader034.vdocuments.net/reader034/viewer/2022051513/547c64a8b4af9fc9158b5116/html5/thumbnails/9.jpg)
Bed Plate Leveling If bed has under adjustment screws
• Same procedure as last
• Some printers can be
adjusted while printing.

Software Leveling MatterControl
• Included Software Print Leveling
• Wizard samples bed at 3 points
• Corrected while printing

LEVELED! Your printer should now be level! What’s next?
• Z-Height
• Filament Settings
• First Layer Speed
![Page 12: Troubleshooting common challenges with 3d printers](https://reader034.vdocuments.net/reader034/viewer/2022051513/547c64a8b4af9fc9158b5116/html5/thumbnails/12.jpg)
Z-Height • Depends on the printer
• Most are z-min
• Common procedure 1. Tighten z-pin
2. Home z axis
3. Adjust z-pin as needed
4. Back to step 2 until just on bed
![Page 13: Troubleshooting common challenges with 3d printers](https://reader034.vdocuments.net/reader034/viewer/2022051513/547c64a8b4af9fc9158b5116/html5/thumbnails/13.jpg)
Filament Settings Common Settings That Will Help You
• First Layer Temp o Just Hot Enough to Stick Well
o Raise the temperature 5°c until sticking well
o Approximately 10-15° hotter than the rest of the print
• Extrusion width of 200% is good
• Make Sure First Layer Height is Tall Enough o Good setting is ½ Extruder Diameter
o .4mm nozzle = .2mm first layer height
![Page 14: Troubleshooting common challenges with 3d printers](https://reader034.vdocuments.net/reader034/viewer/2022051513/547c64a8b4af9fc9158b5116/html5/thumbnails/14.jpg)
First Layer Speed It is Very Simple - Go Slow
• 20 mm/s is a good start
• Make sure moves are also slow
• We set a fixed number rather than a percent
