As I was going through the TAZ 6 auto bed leveling, the firmware returned this data
< Bed x: -9.00 y: -9.00 z: 1.469375
< Bed x: 288.00 y: -9.00 z: 1.519375
< Bed x: 288.00 y: 289.00 z: 0.850625
< Bed x: -9.00 y: 289.00 z: 1.685000
< Eqn coefficients: a: -0.001320 b: -0.000760 d: 1.671742
< planeNormal x: 0.001320 y: 0.000760 z: 1.000000
Based on the 4 “z-axis” values in the above, it looks like the measurement seems to be in 1/8 of a .001 millimeter jumps, in other words, accuracy of .000125 mm. The values vary as much as .83 mm from each other.
So I was wondering whether leveling the bed on the TAZ 6 manually made any sense.
- What is considered a good bed leveling accuracy for a manual bed leveling system?
- Is the TAZ 6 capable of being manually leveled? If it could, I suspect it would either just be a little more or less tight on the appropriate leveling washer, or else some small “shims” in that corner that needed it. Perhaps the metal plate holder for the bed should have some metal angle brackets or similar on it to keep it from flexing (which it clearly does).
- Would it produce a better print than just doing an auto-leveling?
