Lulzbot Taz 6 leadscrew indicator

Align your X-Axis with ease using simple indicators that ensure a perfect lineup.\r\n\r\nSecure the indicators[1] in place - verify the one on the leadscrew is high enough to avoid collision with the fixed indicator. Don't tighten the one on the leadscrew yet.\r\n\r\nStraighten out your X-Axis (this handy guide will help: https://www.thingiverse.com/thing:2992448) and adjust each leadscrew indicator so its pointer lines up precisely with the fixed indicator.\r\n\r\nYou can rely on a Mk I Eyeball to check the axis alignment whenever needed, using a useful technique like jogging Z at 0.1mm per click on the control knob (a hint: this method is especially helpful).\r\n\r\n[1] - To fit these indicators, you'll need to partially remove the lead screws; I wouldn't have done it if I hadn't encountered a cracked connector (the giveaway was a ticking sound on Z moves). Lulzbot uses locktite or similar on the connector grub screws, and I had to apply heat to loosen them.\r\n\r\nThe process is straightforward:\r\n\r\n1. Jog the X beam to its middle point within the Z travel range.\r\n2. Release the leadscrew connectors (just from the leadscrew; you can leave them attached to the motors).\r\n3. Remove the printed top Z plates from the frame.\r\n4. Lift the X-Axis so the bottom of the leadscrews is exposed and remove the bottom bearings.\r\n5. Install the leadscrew indicators onto the leadscrews (I'd fit the M2 clamp screws & nuts beforehand).\r\n\r\nAs all good manuals advise, reassembly is simply the reverse of disassembly.
