Recommendations to Improve Printer Stability

These recommendations apply to both stock firmware and ZMOD.

---

Install the Latest Stock Firmware and ZMOD Updates

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.

---

Replace Spiral/Auto Z-Hop

The printer does not support this feature.

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

---

Disable "Arc Move" Approximation

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

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

---

Disable the Built-in Camera on the Printer Screen

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 ZCAMERA_ON macro.

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

---

Disable Chinese Cloud Services

Only FF5M/FF5MPro

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, use the Telegram Bot.

More about Chinese cloud services.

Avoid Using Russian Characters in Filenames

If you use object exclusion and filenames contain non-English characters, the printer may fail to resume prints correctly. Rename files using English characters.

Filenames should not start with numbers, as this breaks print recovery.

---

Enable [MD5] Checksum Control

1. Add CHECK_MD5 to your workflow.
2. Modify post-processing scripts to include addMD5.bat (Windows) or addMD5.sh (Linux).

In Orca:
Process Profile -> Advanced -> Post-Processing Scripts -> Add:

C:\path\to\addMD5.bat;

Send Files via "Octo/Klipper" for Printing

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

---

Enable Fix for E0017 Error

E0017 Fix

Enabled by default.

---

Enable Fix for E0011 Error

Resolves E0011 and Communication timeout during homing errors.

E0011 Fix

Experimental feature — disabled by default.

---

Verify Stock OS File Integrity

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.

---

Enable Nozzle Collision Detection

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.
