These recommendations apply to both stock firmware and ZMOD.

Enable object exclusion in Orca:

• Process Profile -> Other -> Custom G-code -> Check Exclude objects
• Process Profile -> Other -> Custom G-code -> Check Label objects

Only the latest version of ZMOD is actively supported.

The developer lacks resources to maintain older versions, so install the latest stock firmware and ZMOD updates.

The printer does not support this feature.

In Orca: Printer Profile -> Extruder 1 -> Z Hop Type -> Set to Normal or Slanted.

While the printer supports arc moves, they reduce print quality and may cause errors.

In Orca: Process Profile -> Quality -> Precision -> Uncheck Arc Move Approximation.

The built-in camera consumes excessive memory and offers poor image quality. Use an alternative camera instead.

On the printer screen: Settings -> Camera Tab -> Disable Camera and Video toggles.

Then, run the CAMERA_ON macro.

• What is an alternative camera?
• I installed ZMOD, and my camera disappeared! It worked in Orca-FF!

These services are unstable and may disconnect intermittently. Reconnection attempts can overload the printer with queued requests, causing errors.

Disabling them also enables faster dialog closure after printing and native bed leveling via the screen.

On the printer screen:

1. Settings -> WiFi Tab -> Network Mode -> Enable Local Network Only.
2. Settings -> Cloud Tab -> Disable FlashCloud and Polar3d.

Instead, you can use:

• zmod.link - cloud, for managing printers via Fluidd/Mainsail.
• Telegram bot.

Add CHECK_MD5 to your workflow.

It is recommended to use the global parameter FORCE_MD5 SAVE_ZMOD_DATA FORCE_MD5=1

Add addMD5.bat or addMD5.sh for Mac/Linux to your post-processing scripts (don't forget to add executable permissions to the file chmod +x addMD5.sh) or addMD5.py it's located in mod. More details*

You can also use Go binaries built for the main architectures from @asd2003ru:

• addmd5-darwin-amd64 (MacOS Intel). Don't forget to run chmod +x addmd5-darwin-amd64
• addmd5-darwin-arm64 (MacOS Silicon). Don't forget to run chmod +x addmd5-darwin-arm64
• addmd5-linux-amd64 (Linux). Don't forget to run chmod +x addmd5-linux-amd64
• addmd5-windows-amd64.exe (Windows)

Download it to your computer and then add it to Orca. Process Profile -> Other -> Post-Processing Scripts.

Here are the options for adding:

• "С:\path_to_file\addMD5.bat";
• "C:\python_folder\python.exe" "C:\Scripts\add_md5.py";
• "/home/user/addmd5-linux-amd64";

The native FF protocol occasionally transfers corrupted files and lacks metadata support for the Telegram bot.

In Orca:

1. Click the WiFi icon next to the printer.
2. Set:
   • Protocol: Octo/Klipper
   • Hostname: Printer_IP:7125
   • Host URL: Printer_IP or Printer_IP:80

If using Mainsail, specify only these thumbnail sizes: 140x110/PNG, 64x64/PNG

In Orca, Printer Profile -> General Information -> Advanced -> G-Code Thumbnails

Note that the native screen will no longer display thumbnails.

E0017 Fix

Enabled by default.

Resolves E0011 and Communication timeout during homing errors.

E0011 Fix

Experimental feature — disabled by default.

Improper printer shutdowns can corrupt the filesystem, leading to minor or major bugs.

The CHECK_SYSTEM macro checks file MD5 hashes and repairs symbolic links if needed.

Disabled by default. Enable using the NOZZLE_CONTROL macro:

NOZZLE_CONTROL WEIGHT=0

This halts Klipper if the nozzle scratches the bed or a part detaches. Highly recommended for users employing nozzle pre-cleaning routines.
