IS THIS MODEL RIGHT FOR YOUR MACHINE?
F731 May Be a Good Fit If You Need:
Good fit for
- You need PC or network control of a CNC machine
- You run production lines or multiple machines from one PC
- You want offline processing to continue if the PC fails
- You need higher-speed motion and expanded communication
Consider another model if you need
- You want a standalone handheld with a fixed display
- You need only a simple 3-axis router
- You prefer a compact monochrome workflow

REPLACEMENT & UPGRADE NOTES
Ordering F731 as a Replacement.
F731 is an installed control architecture rather than a handheld swap. Axis count is 3-5 published (2-6 configurable); confirm configuration, board revision and host-PC software with CINKR.
- F7X pulse spec conflicts across documents (4 vs 10 MHz)
- Axis configuration must be confirmed for 5-6 axis builds

F731 — Questions to Check Before Ordering.
Does F731 work without a PC?
It supports fully offline work: if the computer fails during processing, the system continues and can be re-controlled after recovery.
How many axes can F731 handle?
The controller is published for 3-5 axes (configurable 2-6); confirm the exact machine configuration before ordering.
Can F731 control multiple machines?
Yes, one computer can control multiple machines over the network, which fits production lines.
Which pulse rate does F731 deliver?
The model page states 10 MHz; the F7X series page states 4 MHz. CINKR confirms pulse capability by hardware revision before recommending a specific unit.
