Calculators and reference
Free, no account, nothing to install. The ones marked planned are on the way — this list is the roadmap as well as the index.
Steps-per-mm calculator
Leadscrew pitch, microsteps, pulley and gearbox ratio, converted to the controller configuration value.
Planned
Motor torque converter
N·m, kg·cm, oz·in and lb·in, converted both ways.
Planned
Max feedrate checker
Steps/mm times the controller's max step rate, converted to mm/min — flags anything past 100 kHz.
Planned
Modbus RTU frame builder
Builds a Modbus RTU frame with a correct CRC-16, pre-loaded with the Tstep-087 and TIO-0808 register maps.
Planned
Tiny-DRAW
The CNC drawing/CAM tool. Already built elsewhere — mount at /tools/tiny-draw/ once the Google Fonts CDN link and the favicon path are fixed.
Planned
Stepper power-supply sizing
Motor count, current and voltage, converted to an SMPS or transformer rating.
Planned
Stepper torque-speed estimator
Inductance, supply voltage and current, converted to a usable RPM range.
Planned
Feeds and speeds
Chipload, flute count and spindle RPM, converted to a feedrate.
Planned
RS-485 bus planner
Cable length, baud rate, stub length, termination and biasing, checked against the RS-485 spec.
Planned
Driver DIP-switch selector
Motor rated current, converted to the exact Tstep DIP switch pattern.
Planned
G-code quick reference
The G and M codes a controller interprets, what each does, which are modal, and which differ between controllers.
Unit converter
mm/inch, mm/min to IPM, torque and power, all in one place.
