+==== Maintenance ====
+=== Tightening the V-slot wheels ===
+{{:axidraw:axidraw_wobble.jpg|}}\\
+When the Axidraw arm feels wobbly, tighten the eccentric nuts on the carriage to firm up the motion.
+== Locations of the eccentric nuts ==
+{{:axidraw:axidraw_nut_x.jpg|}}\\
+The big wheels on the X-axis can be tightened here. Use a number 10 wrench. Only 2 big wheels need tightening.
+{{:axidraw:axidraw_nut_y.jpg|}}\\
+The smaller wheels on the Y-axis can be tightened here. Use a number 8 wrench. Only 2 small wheels need tightening.
+== Procedure ==
+  * No need to loosen any bolts first.
+  * Turn the eccentric nut one way or another. The direction doesn't matter. One way will be tighter, the other will be looser.
+  * Work in small increments and feel with 1 finger if one of of the V-slot wheels can be rotated so it's slipping. If the wheels rotates, tighten the eccentric nut a little more and test again. When it's snug against the aluminum profile and doesn't slip anymore, it's good to go.
+  * Wait 15 minutes and move the axes back and forth carefully. Feel for little bumps. If the tension was set too high, the wheels could be squished a little, resulting in bumps. If so, release some tension, wait another 15 minutes and feel for bumps again.
