D3D v18.07 Software

Background

There are 3 places where software may be configured when developing new versions of the OSE 3D Printer. The Cura used here is D3D Lulzbot Cura.

1. Marlin - see Github repo - https://github.com/OpenSourceEcology/3D-Printer-OSE-Marlin/tree/master/D3D%201807%20Marlin/OSE_Marlin . Go up 2 directories to enable download of entire contents.
2. Configuration file (.ini) in Cura - File:D3D v1807 Profile.ini. Start and end g-codes in Cura - are contained in configuration file. Print Settings in Cura - are also contained in configuration file
3. Machine Settings in Cura - contains bed size, z offset, number of extruders, presence of heated bed. And E steps per mm of filament. This is the only place to set presence of heated bed. Note that machine settings are saved in Cura, so when you restart Cura, you can use the same machine settings. Note also that upon first run, the nozzle size selection shows up. Point - be careful about where settings are put - as nozzle size can be changed in Machine Settings in Cura and Print Settings in Cura - and in the Cura command line. See Cura Machine Settings Notes

Note also that EEPROM Settings may affect the way that the 3D printer works.

Startup From Scratch

• If you have a different printer that you want to use - load Cura
• Upload OSE Marlin to the new OSE printer
• Then install proper configuration file for that printer
• Then in Cura, go to Machine -> Machine Settings to correct all settings

Notes

1. Machine settings currently on OSE Linux v1.0 - heated bed needs to be turned on:

To Get Proper Prints with a New Extruder

1. Verify e-steps for the extruder - and make sure Cura machine settings are consistent.
2. Test extruder - so it's extruding correctly with Cura interface
