Option A: Modify the Generic Siemens 3/4 Axis Post (Free, but Risky)
Mastercam installs a generic "Siemens 840D" post by default. You can tweak this for the 828D. Pros: Free
- Pros: Free.
- Cons: The 840D is a higher-end control (multi-channel, complex kinematics). The 828D is a compact control. Direct copying leads to "Channel not available" alarms. You will need to edit the
.pstand.psbfiles using a text editor—advanced skill required.
5. Subprogram Support (EXT and CALL)
Siemens uses EXT to call external subprograms. Your post should be able to output operations as separate .SPF files or use CALL "PART_OP" for modular programming.
2. Plane Switching (G17/G18/G19) with Traori
If you have a 5-axis or 3+2 machine with the 828D, the post must manage TRAORI (tool orientation management). Without it, rotary moves are dangerous. The post must insert TRAORI at the start of multi-axis paths and TRAFOOF at the end, then manage the kinematic chain.
Common configuration choices and trade-offs
- Pre- vs post-programmed tool offsets: embedding H numbers in T commands vs separate tool table usage—choose based on shop workflow.
- Use of subprograms vs long single programs: subprograms reduce repetition but require consistent call/return syntax for 828D.
- Whether to output Siemens macro calls for complex operations (probing, toolbreak) or use plain G-code — macros add power but must match control macros.
- Format for spindle speed and feed units: forcing mm/min avoids feed-per-rev confusion on milling ops that might switch spindle on/off.
