LULZBOT TAZ5-6 Z-Axis Calibration tool

thingiverse

We operate a commercial-grade 20+ machine print farm (Taz5,6) that runs 24/7 and requires quick calibration on the fly. Eyeballing the Z-Axis on both sides of the steppers wasn't precise enough to achieve flawless prints. To overcome this challenge, we created a simple jig that attaches to each side of the printer's top for sub-mil accuracy on the Z-Axis. This jig is easy to create and can be secured with zip ties to the top of the printer (see photos). A measuring tape or steel ruler is used to measure the distance from the head bars to the printer's top. We calibrate our machines every weekend, and this jig significantly speeds up the process by 100 times while delivering 100% accuracy. The Taz6 works best with this jig using the inside slot, which almost provides a perpendicular measurement with a ruler. However, we use the outside edge of the steel ruler to achieve a true perpendicular measurement from head rods to top. For the Taz5, the middle slot isn't ideal due to the head rail's position being set back slightly more than on the Taz6. In this case, using the outside edge works best. We hope this jig helps you achieve more accurate prints.
