Your post must allow you to activate CYCLE832 via Mastercam’s "Text" or "Misc" integers. Without this, your finishing passes will lack the smooth acceleration/deceleration needed for die and mold work.

Most CNC controls read G-code line-by-line in a modal fashion. The Siemens 828D, however, operates heavily on software boundaries and parameterized cycles (CYCLE83, CYCLE84, CYCLE832). It also uses different codes for High-Speed Machining (HSM). Your post must allow you to activate CYCLE832
Even with a good post, you might see errors. Here is a quick troubleshooting guide: (Alarm: Unknown G code) M29 S1000 (Alarm: Siemens
The post should convert Mastercam’s standard drilling and tapping operations into Siemens cycle format, not long-hand G-code. This keeps the program size small and allows the operator to edit peck depths or dwell times easily at the control.
Before running any Mastercam program, ensure your 828D is set to "DIN/ISO" mode, not "ShopMill" mode. Press the "Program" button, then select "New" and choose "DIN/ISO" . Trying to run G-code in ShopMill mode will result in a syntax error.
When purchasing or customizing a post for the 828D, ensure it includes the following:
