3D Printer - Metric Cerberus Delta Bot
|3D Printer - Metric Cerberus Delta Bot|
|Owned by||So Make It|
This printer was the result of this project. It is a "Delta" style 3D Printer, other oddities are that it uses spectra line to drive the A, B and C carriages, it has a bowden extruder, and it uses Force Sensing Resistors to level the bed in firmware by probing. Cerberus is easy to use, quite tall and by far the fastest printer in the space, however it is limited to printing in PLA only.
How to Use
- Generate a toolpath using one of these configurations in Slic3r
- Fast PLA - Fast printing, coarse quality.
- Fine PLA - Fine quality, longer print time.
- Spiral PLA - Single continuous perimeter with no infill.
(right click -> Save link as...) Once Slic3r is installed load the configuration file with File -> Load config, then add your model in STL format, change any setting you might like to, then click export gcode.
Now sit back and enjoy your print. There is no need to pre-heat, Cerberus starts up very fast. Turn the power supply off when you are done.
If you need to stop Cerberus
- Click -> Stop Print.
- Click -> Prepare -> Cooldown.
- Click -> Prepare -> Auto Home.
If you are unsure, just turn the Power Supply off and look for Mark or Bracken.
The printer uses a fork of marlin by Beanz for the FSRs, currently it is kept, with the config that was used, in this repository: https://github.com/so-make-it/Marlin4Cerberus
The Slic3r configurations above are in this repository: https://github.com/so-make-it/Config4Cerberus
There is a monthly maintenance check-list printed in the space, source is here: https://github.com/somakeit/operations/blob/master/Printer%20Service%20Schedules/Metric%20Cerberus%20Service%20Schedule.ods
