FAQ

B51 — Questions to Check Before Ordering.

Why do B51 specifications differ between documents?

B5X information varies by hardware revision and document version for memory, communication and pulse frequency. CINKR treats those fields as requiring verification and confirms against the actual controller label.

Does B51 support a handwheel?

The expanded B51 board configuration supports handwheel operation; confirm the board variant with CINKR.

Can B51 replace a monochrome A1X controller?

It is a platform upgrade requiring interface-board and wiring review. B51 is 3-axis, so it fits parallel machines but is not a drop-in swap.

Which files does B51 process?

Standard G-code with simulation preview; confirm CAM output with the manual.
