Tronxy $4 Bed Leveling Gauge

Not my original design! VegasGuy is awesome and I just stole his idea and applied it to a couple of other printers. This 2020 model should fit on dozens of models out there. DO NOT LEAVE THE GAUGE ON YOUR PRINTER WHILE PRINTING! YOU WILL DAMAGE YOUR PRINTER. This gauge mount makes it fast and easy for you to level your X-axis gantry with your entire printer bed, corner-to-corner to within +/- 0.01mm of accuracy or better. Your 1st layer will be the most uniform it's ever been regardless of whether you have auto-leveling or not. It is also a great diagnosis tool for bed leveling problems. It allows you to readily see precisely how your bed leveling efforts are affecting your bed. It's much, much faster than printing a calibration grid in order to find low and high spots. In other words, you can see your adjustments "LIVE" as you make them. There are a few different versions of these tire tread depth gauges so make sure you buy the same one. This is the one I bought for $4 and some change: https://www.ebay.com/itm/0-25-4mm-Digital-Car-Tyre-Tread-Depth-Gauge-Tester-Meter-Measurer-Tool-Black-LJ/112664501069?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649 Here is the same gauge on Amazon with much faster delivery: https://www.amazon.com/Audew-Digital-Tread-Depth-Gauge/dp/B076MX7J6X/ Mounting the Gauge Put the extruder in the Home position. Turn printer off and center the extruder in middle of the bed. Leave it there. Attach the gauge so the probe is reading the left edge of the bed. Zero the gauge. Move the gauge to the right side of the bed and take a reading. Example for a negative reading: Right side reading is -0.20. Divide -0.20 by 2 = -0.10. Multiply -0.10 by -1 (negative one) = +0.10. Adjust the right Z-motor until it reads +0.10. Example for a positive reading: Right side reading is +0.20. Divide +0.20 by 2 = +0.10. Multiply +0.10 by -1 (negative one) = -0.10. Adjust the right Z-motor until it reads -0.10. Now let's check if we are level. Zero the gauge while it is still mounted on the right side. Move the gauge back to the left side of the bed and take a reading. You should now be within +/- 0.01mm of level. If not, repeat one more time. If you repeat these steps a second time you can usually achieve 0.00mm to 0.01mm of leveling. Using the Gauge the Easy Way Put the extruder in the Home position.
