Orca setup

We'll be talking Orca Slicer here.

By Sunday, I'll post my Orca files and where to put them in Orca. As of this post, my focus has been on improving the seam. A Bowden tube can be challenging to get the seam working.

Here are my thoughts & approach to how I have been using Orca Slicer over the past month. With about a million combinations of settings, it is a bit daunting to configure or even figure out where to start.

Here's a work in progress guide. I'll update the setup guide as I continue. Here is a public share to the guide.

Here's where the seemecnc github files for Orca will begin appearing

Here's the firmware on the SeeMeCNC github. Any SeeMeCNC Duet2 controlled printer will work with the ARTEMIS firmware files. The Artemis firmware files are the only files I will be updating. BOSSdelta, RostockMAX v4, etc., users need to open the config.g and edit the printer height for their machine.

The following picture shows where to change the height, the printer radius, and other settings that need to match your printer model & arms (molded or carbon fiber).

I'm open to all input and suggestions and shares 3MF Orca project files to try. Be sure to include any notes if you change the acceleration, instantaneous speed change (aka jerk), or other config.g settings in the firmware. I don't feel they need changed because Orca Slicer controls everything, including Pressure Advance.

My approach to Orca Slicer: Get one nozzle size and one filament type working acceptably.

Orca Slicer is very well done in my opinion. It can be used several different ways. Here's some things to know about how I decided to use settings.
There are three main sections for settings in Orca Slicer:
> printer
> filament
> process/object

Once I upload my machine & process settings, you'll be able to get a decent print (I'm still have some error getting "SeeMeCNC Generic" Filaments to show up when selecting our printer).

There's a number of settings dealing with the seam. The accelerations and Instant Speed Change (jerk), as well as wipe, retract before wipe (or not).

Pressure Advance DOES NOT BELONG in the firmware config.g. This is because different filament types & nozzle sizes have different compressibility (hysteresis) and require different values for each combination. We can have the same roll of PETG and change from a 0.4 nozzle having 1.2 pressure advance to a 0.7 nozzle which requires about 0.5 pressure advance. It was just this morning, I decided to zero "printer settings" and stick with all of the setting overrides for the filament and nozzle combination. Please give feedback if you have a different idea, just maintain your sanity when trying different things.

A guide to help you get started. I'll be active on this from time to time this month.

Get Started Testing

Updates to the guide in the previous post work very well. The 04 and 07 project files work good with the exception of short travels moves with small features.

More work is needed to properly combine the inherits into the SeeMeCNC "fdm_xxxxxxx_common.json" files. As the Orca Team advised last year, we start with an existing set of profiles. So we picked a voron 350 model and an flsun model. So looking at the machine, filament, and process files, the "inherits" need to be combined into the common.json files in the SeeMeCNC folder.

Today, we will add a 0.5 nozzle PETG project file to our github seemecnc firmware playground. Then later this week add 04, 05, and 07 PLA project files.

As time permits, I'll continue to work on this. I'm not sure I'll have enough time to finish before next month, we'll see.
