PrintNC Pro assembly *timelapse*

Introduction

This tutorial provides a step-by-step guide for assembling the PrintNC Pro, a CNC machine with notable improvements over the standard PrintNC. Inspired by enhancements from Logan Fraser, this guide will walk you through the assembly process, highlighting key components and tips for a successful build.

Step 1: Prepare Your Workspace

• Choose a spacious area to assemble your PrintNC Pro.
• Keep all your tools and parts organized for easy access.
• Ensure you have the following tools ready:
  • Wrenches (various sizes)
  • Screwdrivers (flathead and Phillips)
  • Allen keys
  • Measuring tape

Step 2: Assemble the Frame

• Start with the Y-axis frame:
  • Use 3"x2" steel beams for the vertical supports.
  • Securely attach the beams using appropriate bolts and nuts.
• Move on to the bottom support:
  • Use 3"x1.5" steel beams.
  • Ensure that the frame is level and square.
• Finally, install the X gantry:
  • Use the 4"x3" steel beams.
  • Make sure the gantry can move freely along the Y-axis.

Step 3: Install the Baseboard

• Take the 1/2" aluminum plate as the baseboard.
• Position it securely on the assembled frame.
• Ensure it is aligned with the 999 (37x27) holes:
  • These holes should be tapped with M6 threads for proper installation.

Step 4: Setup the Work Area

• The work area of the PrintNC Pro measures 950mm x 700mm.
• Make sure that any additional components or tools do not obstruct this area.
• Double-check the measurements to confirm they align with your design specifications.

Step 5: Attach the Electronics

• Install the necessary electronic components:
  • Connect the power supply, stepper motors, and control board.
• Ensure all connections are secure and properly insulated to avoid shorts.
• Test each component before proceeding to the next step.

Step 6: Calibration and Testing

• Once assembled, it’s crucial to calibrate your machine:
  • Check the movement of the gantry and ensure it operates smoothly.
  • Adjust the steps per mm settings in your control software.
• Perform a test run to verify that all axes are functioning correctly.

Conclusion

Assembling the PrintNC Pro involves careful planning and execution of each step, from preparing your workspace to final calibration.
