Objective

X-SCARA is a project that intends to bring the SCARA mechanical model to the world of open-source 3D printing machines, with the same functionality and ease of use as the other popular mechanical models (e.g.: Cartesian, CoreXY, Delta).

Building, configuring and calibrating the X-SCARA machine must be painless.
That is our goal!

Hardware

Updates: 
- X-SCARA hardware is now at revision 5!
- Added test-part accessory to calibrate your printer before you start printing X-SCARA
- Added heated bed support directly connected to the X-SCARA frame

The hardware section will contain everything you need to build X-SCARA, from the B.O.M. to STL files and detailed assembly instructions.

Check the hardware section here and if you want to check for updates and/or new accessories take a look at the changelog.

Firmware

Updates:
- X-SCARA firmware version is now 0.4 BETA!
- All basic functionality (homing, bed-leveling, tuning segmented movements) implemented & working
- Added coordinate transformation modes to support bed-leveling (`M360 M2` - probe mode)
- Implemented homing sequence `G28` 
- Modified UBL (Unified Bed Leveling) to support **X-SCARA**'s kinematic model
- Integrated bed-leveling support `G29`
- Applying bed leveling for planar moves when bed-leveling is activated
- Modified `M665` for configuring machine's settings
- EEPROM support to save most important configuration options

For firmware build and configuration follow these instructions.

if you are already using it check the changelog for any updates.
