CNC controllers are the brain of a cutting or machining centre. They take G-code from CAM and handle interpolation, cut-speed control, arc voltage height control (THC), pierce sequencing, torch collision handling and I/O interlocks — which together decide dimensional accuracy and edge consistency. The Icyrobot controller range covers laser cutting, lathe and machining centre applications.

Four hard specs for cutting controllers
| Spec | Why it matters | Typical requirement |
|---|---|---|
| THC response | keeps arc length constant over uneven plate; drives squareness and dross | lift speed ≥ 1 500 mm/min, sampling ≤ 5 ms |
| Pierce sequencing | thick plate pierce with early retract blows slag back into the nozzle | programmable pierce height, dwell and ramp-up curve |
| Corner slowdown | high speed through corners over-burns or under-cuts | automatic angle-based deceleration with look-ahead |
| EMC design | plasma HF start is a severe interference source | fully isolated I/O, shielding and grounding rules, watchdog reset |
Product line
- MNC-LB laser cutting CNC — for fibre laser machines: flying-optics compensation, focus following, automatic edge finding, resume from breakpoint;
- 1000TA lathe CNC — economical lathe control with threading, cycles and tool compensation;
- MS-1000TB / 2000TB lathe CNC — expanded dual-channel version for lathes and turning centres;
- 1000M / 2000M machining centre CNC — milling control with multi-axis interpolation and macro programs.
Closing the loop with CAM
A controller can only do as well as the CAM description of the process allows. StarCAM and Icyrobot controllers share one process-parameter model, so cut speed, kerf compensation and pierce data synchronise both ways — avoiding the classic gap where the nesting looks perfect and the cut is a mess.
Five questions to ask before buying
- Is the machine gantry or portable? Portable units demand more from size and vibration tolerance.
- How many interpolated axes, and is there a bevel head? Bevel cutting needs an extra rotary axis with RTCP.
- Which power source? Plasma, flame and laser use completely different interfaces and height sensing.
- Must it talk to MES or scheduling? Confirm the interface and data format.
- Service and spares — availability and lead time for mainboards, pendants and drives.
Frequently asked questions
Can a new controller retrofit an old cutting machine?
Usually yes — it is the most common request. Assess the machine's mechanical condition first: guideway wear and backlash. A worn machine will not gain much accuracy from electronics alone.
My arc voltage height control is unstable. What should I check?
Check that the arc voltage sense cable is independently shielded, that the divider ratio matches the power source, and that torch cables are routed away from power cables. Nine times out of ten the fault is wiring or configuration, not hardware.
Does it support resume from breakpoint?
Yes. The controller records line number and position, so after a power loss or lost arc it can re-start a few segments before the break instead of scrapping the sheet.
Can it run plasma and flame torches together?
Yes, with a dual-torch configuration. The two processes sense height differently — arc voltage versus capacitive — so hardware and parameters must be set up separately.

Frequently Asked Questions
Can an old cutting machine be retrofitted?
Usually yes — it is the most common request. Assess mechanical accuracy, guideway clearance and drive type first; a badly worn machine will not gain much from new electronics.
My THC is unstable — what should I check?
Check that the arc voltage sense cable is independently shielded, that the divider ratio matches the source, and that torch cables are routed away from power cables. Nine times out of ten it is wiring or configuration.
Does it support breakpoint resume and dual torches?
Yes to both. Breakpoint resume restarts a few segments before the stop; dual plasma/flame torches are supported but need separate height-sensing setup.
