D3D Lulzbot Cura

Introduction

Lulzbot Cura allows for ready setup of machines other than Lulzbot and Lulzbot Mini. As such, it is useful to use Lulzbot Cura for OSE's D3D 3D Printer.

By going to Expert-> Switch to Full Settings - you can set nozzle size and various parameters. Once all configuration has been input, you can save the profile as a .ini file.

To configure a new machine (bed size) go to the menu - Machine-> Add New Machine - you can add a profile for the D3D Original - 8" print bed.

Configuration Profile - Files

Configuration (.ini) file for D3D Lulzbot Cura:

File:D3DOriginal config.ini - D3D Original, 16" frame, 8" print bed, 0.5 mm nozzle.

Calibration

Motion

From Triffid Hunter's Calibration Guide:

Start with D3D BOM - the pulleys are 20 tooth?

Yes, and the magic number is 80 steps/mm for x, y, and z.

Extruder

Doing a 100 mm extrusion in Pronterface yielded 4.6 times that length! The Extruder steps/mm are 4.6 too high. Reduce them accordingly. Go to D3D Marlin. The April 27, 2017 version has E steps/mm = 500. That number was pulled out of ass. It should be 109, which is consistent with this MK8 extruder discussion.

Override can be done using M92 E109. I can try that in the Startup Gcode within Lulzbot Cura, but first can set M92 E109 temporarily in Pronterface.

Doing the test, I got 109 mm extruded, so it is really M92 E100. Is that by design of the MK8 extruder or coincidence? Exactly 100 steps per 100 mm of filament pushed?

OSE Marlin can remain as is - but the File:D3DOriginal config.ini is changed to override the Extruder Steps/mm that is set in Marlin.
