CNC Controllers

Custom G-Code Generation for Different CNC Controllers

Many shops run several controller brands side by side. The same CAM toolpath must become quite different code for each, while the shop's standards stay consistent.

One operation, five dialects

A tool change, work offset and length compensation for tool 5:

ControllerOutput
FANUCT5 M6 / G54 / G43 H5 Z50.
HaasT5 M6 / G54 / G43 H5 Z50. (+ Haas options such as G187)
SINUMERIKT5 M6 or T="NAME" / D1 / G54 / Z50
HeidenhainTOOL CALL 5 Z S8000 / preset or datum cycle / L Z+50 R0 FMAX
Okuma OSPT5 M6 / G15 H1 / G56 H5 Z50.

What differs between controllers

  • Tool call and length offset method.
  • Work offset selection and extended offsets.
  • Canned cycle syntax (G81 vs CYCLE81 vs CYCL DEF 200).
  • Arc format, planes and helical support.
  • High-speed modes, TCP and tilted plane functions.
  • Comments, subprograms, variables and file formats.

Post families

Instead of maintaining unrelated posts per machine, we build a post family: shared logic for shop standards (headers, tool lists, safety blocks), with a controller layer that formats output for each dialect.

post-family/
  common/        header, tool list, safe start, restart logic
  fanuc/         FANUC formatting and options
  sinumerik/     SINUMERIK cycles and frames
  heidenhain/    Klartext output
  machines/      per-machine limits, M-codes, kinematics

Benefits

  • Programmers can post the same job to different machines.
  • Shop standards change once, everywhere.
  • New machines are added faster.
Consistent standards, native dialects: that is the goal of a multi-controller post strategy.
