110mm calibration piece

thingiverse

To make calibration easy, use this large easy to print piece. 110mm for x and y, 4mm height. All squares are 10mm x 10mm. The difference to smaller calibration pieces is that you can find really tiny errors with this. I found a 2% error in my print, 3 mm at this size. A standard 20mm calibration cube would have given you a .4mm difference. Still measurable but a lot more difficult. Instructions Print, cool, measure, calibrate, print again, measure, calibrate again :) Calibration is done like this Get your X or Y calibration value from Slicer. Measure the X or Y length of the piece Use following formula (110 x OldCalib) / Measurement = NewCalib So my old value was 61.2555 for X and I measured 107.50mm. 110 x 61.2555 = 6738.105 6738.105 / 107.5 = 62.6800 So i now have a better calibrated bot!
