All software and configuration files for the PikkoBot Vertex 4, built on the open-source LumenPnP platform.

PikkoBot Configuration Files

Pre-tuned configs with JUKI nozzle calibration. Hosted directly on this site.

Version	Notes
Vertex 4.1.0 (JUKI)	Recommended — pre-calibrated, solenoid fix included
Vertex 4.1.0 (stock)	Official defaults, uncalibrated
Vertex 4.0.1 (JUKI)	Recommended for 4.0.1
Vertex 4.0.1 (stock)	Official defaults, uncalibrated

Which Configuration to Load

The four options are two versions × two nozzle variants. Pick in this order:

1. Match your firmware version first. If your mainboard is running 4.0.1, load a 4.0.1 config. Loading 4.1.0 onto 4.0.1 firmware gives you actuator definitions the firmware doesn't have.
2. Then pick the nozzle variant. The JUKI configs ship with nozzle tip calibration data and the S255 solenoid fix already applied. Take a JUKI config if you're using the nozzles the machine shipped with. The stock variants are uncalibrated official defaults — useful as a reference or a clean starting point, but you'll redo the calibration steps yourself.
3. If you've swapped nozzles, start from stock and calibrate — nozzle tip calibration is specific to the tip geometry.

Switching configs later is fine, but export your current one first. Calibration data you've captured is stored in the config file, and loading over it discards it.

Back up before you load. Machine Setup → File → Export Configuration writes the current config to a file. Do this before loading any config from this page.

Firmware

• Mainboard firmware (Marlin-based)
• Photon feeder controller firmware

Only reflash firmware if instructed. The firmware is pre-loaded — flashing incorrectly may require USB recovery.

OpenPnP Software

OpenPnP v2.6 installers are self-hosted on the PikkoBot CDN for reliable access.

Platform	File	Size
Windows 64-bit	OpenPnP-windows-x64-main.exe	238 MB
Windows 32-bit	OpenPnP-windows-x32-main.exe	193 MB
macOS (Universal)	OpenPnP-macos-main.dmg	243 MB
Linux (Debian/Ubuntu)	OpenPnP-linux-main.deb	188 MB
Linux (tar.gz)	OpenPnP-unix-main.tar.gz	187 MB

Source: OpenPnP v2.6 (2026-03-01). These files mirror the official release from openpnp.org.

Before You Install OpenPnP

OpenPnP needs Java 11 or newer. Check first:

java -version

If that reports 1.8 or fails, install a current JDK before running the installer. The Windows installer bundles a JRE; the macOS and Linux builds do not, and a Java 8 runtime produces a startup error that looks like a corrupt download but isn't.

If the Download Stalls

The installers are 200 MB+. If a download stops partway through:

• Try a different browser — some corporate proxies truncate large binary downloads without reporting an error
• Verify the file size matches the table above before running it. A truncated installer usually fails with a generic "this file is damaged" message
• If you're behind a proxy, the OpenPnP project hosts the same release at openpnp.org as an alternative source

Remote Support

If a setup problem needs hands-on help, we can run a remote session. Any of these work — pick whichever you already have installed:

Tool	Platform
TeamViewer	Windows, macOS, Linux
AnyDesk	Windows, macOS, Linux
Google Meet screen share	Any browser

Email [email protected] with your machine version, what you've tried, and a photo of the machine state. A screenshot of the OpenPnP error dialog saves a round trip.
