CNC & Industrial Controller Repairs, Reconditioning

---

ElecLab delivers elite, engineering-grade component-level repair, rebuilding, and modernization for CNC machine controllers, multi-axis motion electronics, and industrial automation control systems.
Engineered for high-precision manufacturing plants, aerospace production lines, metal-working facilities, and automated fabrication hubs across North America, we restore mission-critical CNC electronics to uncompromising OEM-level accuracy and reliability.

• Metal Cutting & Machining Centers: 3-axis, 4-axis, and 5-axis high-speed vertical and horizontal machining centers, precision turning centers, and multi-tasking lathes.
• Specialized Industrial Cutting Systems: Digital flatbed cutters and automated multi-ply cutting tables (specialized for composite materials, cardboard, technical textiles, leather, and wood routing/engraving systems).
• Additive & Rapid Prototyping Systems: Heavy-industrial grade 3D printing units and large-format automated additive manufacturing controllers.

• Primary CNC & Motion Architecture Brands: Fanuc (Series 0i, 30i/31i/32i, 16/18/21), Siemens Sinumerik (802D, 810D, 840D SL), Heidenhain (iTNC, TNC series), Mazak (Mazatrol matrices), Mitsubishi (M70, M80 series), Allen-Bradley / Rockwell Automation, Fagor, Haas legacy and current-generation controls, Okuma OSP, DMG Mori, Kongsberg, and Gerber multi-axis motion systems.

• Servo & Spindle Drives: High-speed brushless DC (BLDC) spindle motor drives, multi-axis servo amplifiers, PWM power modules, and regenerative braking units.
• Feedback & Precision Resolution Modules: High-resolution optical encoders, magnetic rotary encoders, motor-mounted tachometers, resolver feedback interfaces, and linear scale signal processing boards.
• Axis Motion Electronics: Dedicated drive interface cards, closed-loop position control modules, and current-feedback isolation circuits.

• Industrial Power Regulation: High-power switch-mode power supplies (SMPS), multi-tap step-down transformers, bus-bar distribution assemblies, and line reactors.
• Drive Power Stages: Rectifier modules, dynamic braking transistor assemblies, DC-link capacitor banks, and high-current solid-state power switching boards driving X, Y, Z, and rotary axis motors.

• CNC Motherboards & CPU Units: Central processing units, motion interpolator boards, and RAM/ROM memory storage modules.
• PLC & I/O Interface Cards: Discrete digital/analog I/O expansion boards, safety relay modules, and ladder-logic interface controllers.
• Operator Interface Terminals: Industrial CRT/LCD operator console panels, membrane keyboards, pendant controllers, and touch-screen HMI display units.

• Fault & Error Code Remediation: Expert troubleshooting for common CNC alarm states, including servo lag errors (following error faults), communication timeouts (fiber-optic/serial bus failures), absolute encoder battery/position loss, spindle drive overcurrent/overvoltage faults, and thermal foldback warnings.
• Programming & Parameter Optimization: Parameter backup recovery, CMOS battery replacement, firmware flashing, memory clearing, communication protocol troubleshooting, axis synchronization tuning, and dynamic spindle calibration.
