We do encourage all users to be on the latest release. You are welcome to remain on older versions, but we will only be able to provide limited support (and no bug fixes) to older versions. Please consider upgrading to the latest version.

NOTE: Our environment is intended to be run by the HYREL user in the operating system, with FULL ADMINISTRATOR rights and privileges, on a windows device running in American English as the native language. If you vary from this, results may be unpredictable.

Please note that version 4 and above require a ($250) license key to operate - see Licensing for details.

Please note that you should ensure that your ST-Link is working before you attempt this upgrade.

Please note that if you cannot perform the upgrade yourself, we charge a $100 service fee to help.

Upgrade Overview

The new Repetrel installer will also install the prerequisites, so the process is:

In brief:
1. Repetrel Installer (you are here now)
2. Firmware
3. Settings
4. Recipes
5. Licensing

Current Version: 4.2.524

There are always minor enhancements and bugfixes, so please use 4.2.524, linked below. Feel free to review the changelog.

Which to use?

1. If this is a computer that hasn't run Repetrel v4 yet, please use the "Repetrel Full Installer".

2. If this is a computer that has run Repetrel v4 before, please rename your C:\Repetrel directory to C:\Repetrel_old (or whatever) and use the "Repetrel Installer"

3. If you just upgraded a few weeks ago, and are upgrading again, please use the "Repetrel Installer Light"

This download has it all - Repetrel, firmware, manuals, recipes, AND the Ecosystem Apps setup to install prerequisites. Use this to install in a fresh environment.

Download the file and run it as Administrator.

This download includes the latest (see above) complete Repetrel install, from C:\Repetrel on down, including software and firmware for your 407 (30M, ESR) or 429 (16A, EHR) Motion Controller, your 103 Print Head and Hot Bed Controllers, and controllers for the CO2 laser, 3-phase spindle tool, and extra axes.

Download the file and run it as Administrator.

As there have been some file location changes recently, we recommend renaming your old repetrel folder (perhaps to repetrel_something) and then doing this complete Repetrel install.

This should only be run as an update to an already functioning Repetrel v4.x install. And even then, you are probably better off running the "normal" installer above. :)


For version 3.083_K, please visit 3_Install.

After Repetrel

Please proceed to steps 5-8 to complete your install or upgrade. `
