About this model

This is YACS. (yet another calibration square) Update 24-04-2019 Added new vertical test piece Update 30-10-2017 Added vertical test piece Update 26-10-2017 Flat corners now stand on the exact square corner. Corners are now named. The main difference from most other calibration tests is that the corners are clipped so that you can easily measure the X-Y skew of you printer. Nothing too fancy. You can fix either try to fix it mechanically or use a gcode compensation tool. GSuite is an example. You can downloaded in this [link]. (
