We currently have the following 3D printers:
- Type A machines Series 1. Read that page for more instructions too
Status: Slowly piecing together documentation so that new people can get going. There are several key insruction pieces, but there is nothing that starts from the beginning and takes you to the end of turning on the 3D Printing desktop, clicking on the right software, calibrating the printer, and debugging. The status now is incomplete!
There are several steps in the 3D Printing process.
- Hooking up the 3D Printer to a desktop or laptop computer. Unclear, needs to be written down
- 3D Modelling + 3D Printed Model Software (Google Sketchup, etc) - What we cover in our Today I Learned Workshops
- Repetier-Host - open-source driver software connecting our computer with the 3D Printer
- Printer Calibration (see comics) Only place where we have any documentation
- Act of Printing
- Caring of 3D Printed Objects + More How we remove the 3D Printed object from the printer bed, decorating the 3D Printed object, etc.
Background: Original handwritten piece by Jae. This was the primary documentation for most of the early SudoRoom days and was writen down on a piece of paper. It's quite excellent.
Printer Calibration: Comics
A comic book interpretation of the Printer Calibration instructions from Jae.
Adjusting the Print Beds
- Do not put multiple layers of tape on the glass print-bed: this makes the print-bed less "sticky"
Use the "manual control" in Repetier-Host to
- "Home" the Z (height) by clicking on the Home-Z
- This will move the bed up until ?? switch cliks
- the Z-Switch is pushed by a knob attached to the print bed. If you rotate the knob, it will adjust the global z-height of the print-bed
- Ensure the print nozzle is not touching the tape by pressing Z+ (move the bed down)
- "Home" the X & Y by clicking on HomeX and Home?
- Move the print head around, especially near the [holy scriptures erased] corners of the bed
- Turn the paper over
- Use the allen key on the 4 corner screws to ensure that all four corners are equally far away from the print Nozzle.
- Tip 1: Adjust the Z manually until a piece of paper barely fits under the nozzle. Friction will tell you how big the gap is...
- Tip 2: don't scratch the tape on the print bed!
- Tip 3: There are 4 screws, but only 3 free degrees of motion since the bed is FLAT. So this part is TRICKY. Be patient!
- When satisfied, consider adjusting that global Z-height by turning the knob.
- Tip 1 - the knob is not tight, so secure it with the tape so it doesn't accidentally rotate.
- Tip 2- You want the gap to be exactly 0 zero after "homing" the Zaxis
- Tip 3 - After "homing" z, manually adjusting z by 0.1 mm should cause a visible gap between the nozzle & print bed.
