On new (clean) installs, you MUST run Slic3r.exe BEFORE launching Repetrel. Configure it to run in expert mode, then exit.

Flashing Firmware

New software will often require new firmware. The latest firmware as of 1 Mar 2017 is part of the Repetrel download, above. However, if you only need to upgrade your firmware, download from: http://hyrel3d.net/downloads/firmware/Firmware_2017.05.10.rar

Video instructions for flashing the 103 (HH/HB) Controllers: https://youtu.be/yM8QMZBTb4o

Video instructions for flashing the 407 Motion Controller: https://youtu.be/cFAFRkpLmww

Clench Valves require the primary head to have firmware 49V installed, so that the clench valve is activated (instead of primes/unprimes). Download and flash per instructions above.

Installing Drivers

If, for some reason, you re-OSed or re-imaged your PC, or are installing on a new PC (or your local IT people made some changes preventing you from connecting to the printer), you will need to ensure that the proper drivers are in place. AFTER you have done the install above:

1. Run: C:\repetrel\ST-LINK Utility\Windows 8 Compatibility Resolver.bat

2. Right-Click and RUN AS ADMINISTRATOR: C:\repetrel\DfuSe\Driver\dpinst_x86.exe (or other appropriate file if on another architecture); Click to ALLOW this program to run.

Now, in Devices and Printers, you should see the FT232R USB UART without any alert icon. Congratulations!
