To determine if you require firmware for legacy 103 boards, consult these images:

Please note that the legacy boards with jumpers have not shipped since mid 2014, so most people will never encounter them.

EcoSystem Apps

EcoSystem Apps is a suite of publicly available programs which add many features at no cost. Some of them you might use individually to create or modify models. Others might be called from Repetrel to manipulate a file. This install should all be carried out per the instructions below, so that Repetrel will find them in the expected locations.

Installing EcoSystem Apps

1. Download http://www.hyrel3d.net/downloads/updater/EcosystemApps.exe - see table below for the list of programs and their proper locations.
2. Run the executable, with the location pointed to C:
3. Launch Repetrel, go to the Programs tab, and double click in each text field, pointing the applications to their respective executable files under C:/EcosystemApps. See the table below for the proper locations. Note the new location for the Slic3r install; Slic3r Recipes (or Slic3r CFG files) should still be under C:\Users\Hyrel\AppData\Roaming\Slic3r.
