3D printing calculators

Enter the moving mass, drive geometry, available running torque, and target acceleration to estimate whether a simple printer axis has enough motor torque. The reverse results show the theoretical limit and a lower starting point after your selected torque margin.

Enter a straight feature length, its planned speed, and the speeds at each end to see whether the printer can actually reach that speed. The result also shows the distance and time spent accelerating, cruising, and decelerating.

Enter the belt mass, free span, target tension, and measured pluck frequencies to estimate belt tension and see how far each belt is from the target.

Enter the ripple measurements from a ringing tower to calculate X and Y resonance frequencies, optional fine-tuning values, and firmware-ready input shaper settings.

Enter your Z motor, lead screw, nozzle, and model height to find the nearest full-step-aligned regular layer height. The result also estimates layer count, finished height, and whether the height stays within the common nozzle guideline.

Estimate the first critical speed of a printer Z lead screw, then see the recommended Z speed limit and the longest unsupported length for your configured travel speed.

Enter the three measurements from a skew calibration print to calculate the signed correction factor, angular error, and firmware command for XY, XZ, or YZ skew.

Enter the motor, microstep, gearing, and drive geometry to get theoretical steps/mm. Add a measured extrusion test to convert the current firmware value into corrected Marlin and Klipper settings.

Enter your tested maximum flow, bead geometry, print speed, flow ratio, and filament diameter to see whether the planned extrusion stays inside the hotend limit.

Weigh the spool, subtract the empty spool weight, and see how much filament is left in grams, meters, percent of the spool, and usable copies for your next sliced print.

Enter the motor phase-current rating and your driver RSENSE value to get a standalone VREF setting plus UART IRUN and IHOLD register values. The result also shows the rounded current the driver can actually produce.
