Geeetech A20M profile

[Rockel83 0]

Helo all!

 

I've bought myself a Geeetech A20M printer. Had quite some issues with it already. But I guess few of them were also related to somekind of Slicer issues.

 

I used Repetier-Host before. And I was using the Cura slicer "plugin" here. For which Geeetech provides a profile for. But this Cura version of Repetier looks verry basic. And I think I missed some settings here to improve my prints.

 

I had some temperature issues with some filaments. When printing a bit more hot, then prints stuck to the build plate, but caused overheating at corners in the back. When dropping the temperature, trying fix this then first layers became a mess and prints started to fail quickly.

 

I see that I can use a lot of more advanced settings here in the normall Cura. Which looks pretty awsome so far.

 

But there're a lot of settings!

 

So I was wondering if someone has a decent Cura profile for the A20M.

 

Will be much appreciated!

If you have Cura 4.13.1 there is a printer definition file for the A20M.  I don't know how many versions back it was included.

 

As for a Settings Profile I think you will need to build your own.  As I recall that is a 2-in-1-out hot end.  In the Cura Marketplace (button at the top right) there is a plugin "Printer Settings".  Install it and after restarting Cura it will show up at the very bottom of the settings list.  Within Printer Settings are "Extruders Share Heater" and "Extruders Share Nozzle".  You will need to select both of those.

 

Next to the Settings Search box is the Visibility icon.  Click on it and set it to "All".

 

I would practice with Extruder 2 disabled and print a couple of test cubes.  When those start to look good then re-enable extruder 2 and disable extruder 1 and slice and print again.  Get them both dialed in.

 

I don't own a multi-extruder machine but I've played with virtual ones in Cura.  The retraction distances when switching from one extruder to another, the size of the purge tower, how much material you actually need too purge to switch colors (white is tough) need to be practiced.

There are settings within the Dual Extrusion section of Cura you will need to become familiar with.  In addition, each extruder can have separate starting Gcode that would be added at each tool change.

 

You're right - it isn't simple and there is no "Easy" button.  Maybe someone over on Reddit has a profile you can start with.  There haven't been many A20M owners who have shown up here.  Good Luck.
