Intamsys askelmoottorin ohjain Y/Z/E-akselille INTAMSYS 3D-LISÄVARUSTEET

When a stepper driver on your INTAMSYS 3D printer starts to fail, you need a reliable replacement to keep production running. This INTAMSYS stepper drive (part 803-0503-P02) is built for the Y, Z, and E (extruder) axes, delivering precise motion control with the advanced TMC2209 chipset. It supports 2-phase stepper motors with an input voltage range of 5.5V to 28V DC and a peak output current of 2.8A, ensuring compatibility with a wide range of printer configurations.

Key specifications

• Driver chipset: TMC2209 (high-performance, silent operation)
• Compatible motor type: 2-phase stepper motors
• Input voltage: 5.5V – 28V DC
• Logic voltage: 3.3V / 5V
• Peak output current: 2.8A (RMS: 2.0A)
• Microstepping: up to 256 (interpolated)
• Operating modes: STEP/DIR, UART, SPI
• Silent operation: StealthChop2 technology
• Sensorless homing: StallGuard4
• Dynamic current control: CoolStep
• Protection: overcurrent, overtemperature, undervoltage lockout
• Thermal management: integrated heatsink
• Axis application: Y, Z, E (extruder)
• Communication interface: standard 3D printer pin headers
• Motor current adjustment: digital via UART/SPI
• Compatibility: INTAMSYS 3D printers (replacement/upgrade part)

Why choose it

This stepper drive is engineered for silent, precise operation. StealthChop2 minimizes motor noise, while StallGuard4 enables sensorless homing for cleaner builds. CoolStep dynamically adjusts current to reduce heat and energy consumption, extending motor life. The integrated heatsink ensures reliable thermal performance during long prints.

Ideal use cases

• Replacing a faulty stepper driver on INTAMSYS printers
• Upgrading to quieter, more efficient motor control
• Maintaining consistent extrusion and axis movement in production environments

Good to know

Installation is straightforward with standard pin headers, and digital current adjustment via UART/SPI allows fine-tuning without manual potentiometers. Always verify compatibility with your specific INTAMSYS model before purchase.
