• Disclaimer for bad boards, wrong screws, etc*
• We need to address the X-endstop problems here, and probably recommend putting it on the left*

1. 1. <a name="marlin"></a>Marlin Firmware Upgrade

The version of Marlin that Folgertech has put together is pretty outdated. It does not include a lot of new features (like autolevel) and bug fixes. It is recommended that you upgrade to this version (the wiki software won't let me make external links because it doesn't trust me), which is the latest release version of Marlin with the Folgertech configuration settings merged in. Please note that you will need to make some changes to your printer to get this working correctly/properly (unless you moved your X-endstop to the left side):

• Move your X-endstop connection on your RAMPS board one set of pins over, to position 6
• In your host software, change X-endstop setting to MAX

1. 1. 1. Raising the Z-axis motors

This is a simple print upgrade that will recover some height lost by the Z-axis motors being mounted directly on the top rail. Print these raisers (the wiki software won't let me make external links because it doesn't trust me) to gain about 40mm of print height.
