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. Motor torque converter N·m, kg·cm, oz·in and lb·in, converted both ways. Max feedrate checker Steps/mm times the controller's max step rate, converted to mm/min — flags anything past 100 kHz. 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.
Tiny-DRAW The CNC drawing and CAM tool. Planned
Stepper power-supply sizing Motor count, current and voltage, converted to an SMPS or transformer rating.
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. RS-485 bus planner Cable length, baud rate, stub length, termination and biasing, checked against the RS-485 spec. Driver DIP-switch selector Motor rated current, converted to the exact Tstep DIP switch pattern. 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.
