Ryan's X & Y Calibration Step Triangle

thingiverse

I designed this model to test the calibration of a new printer. It checks the X and Y resulting accuracy in graduated steps, as well as overall length up to 290mm on X and on Y. NOTE: This is 290 x 290 mm. It is for larger printers. Care should be taken that you do not have binder clips in the nozzle path. This hazard exists on CR-10, but not on CR-10-S4 printers. I build a Shapeoko printer 3 years ago. I needed to double check dimensional accuracy of prints. This has raised blocks which can be measured with smaller or larger calipers, both along the X and Y axis, and diagonal. It can be used to some extent to calibrate the Z axis as well, at least in determining your initial starting layer settings. If there is interest, I will modify with marks for heights at different block sizes. If you are building a new printer, or just checking out the accuracy of a new one. There is often a happy medium you can achieve by tensioning belts. If your printer is coming up short on one axis, and there is safe tension which can be increased, this print will help get you spot on. Trying to help. -Ryan
