  • Page 2 Something You Need to Know Before Getting Too Excited…...
  • Page 3 Something You Need to Know Please note that SecKit tries to be helpful and provides as clear instructions as we can, but we will not be responsible for any of your loss caused during assembly process.
  • Page 4 Something You Need to Know Linear Blocks Every linear block comes with a plastic rail. NEVER leave the block along. ALWAYS keep a rail under the block. Those tiny steel balls will fall out and you will cry.
  • Page 5 Something You Need to Know How to move linear Linear block blocks onto linear rails? Plastic rail Linear rail Connect plastic rail and linear rail Linear block Plastic rail Linear rail Carefully move linear block across the rails Linear block Plastic rail Linear rail Remove plastic rail...
  • Page 6 Something You Need to Know Clean linear rails • Lubricating oil • Tissue or cotton swobs Action After the rails being cut, some dirt and particles will stay on the surface, so linear block won’t move smoothly. Wipe those dirt out with lubricating oil and tissue before assembly, and always keep the rail oily to prevent from rusting.
  • Page 7 Something You Need to Know Make sure you build it right in each step Parts to be prepared Errors will accumulate along with each step in your assembly progress. To get a solid machine you must build it correctly. Each page in this manual is written in a similar structure.
  • Page 8 Something You Need to Know Assemble on a flat & solid surface (O) Stiff and heavy table, large tile, granite table, etc. (X) Carpet, thin and unstable desk, etc.
  • Page 9 Something You Need to Know Fasten bolts diagonally If there are multiple bolts, fasten them in a diagonal sequence. Also tighten screws with proper force to prevent from damaging threads .

You can connect to Servo42 with the attached micro USB cable and these free software tools: SerialTools (Mac) or Serial Port Utility (Windows).
  • Page 108 Part-Cooling Fan Configure Step Motor Driving Current Lower current can be silent but more likely to loose step at high speed. According to experience, 500mA for XY steppers is a good point to begin with. If you’re using Servo42s, you’ll print silently if setting max current to 300mA and hold current to 100mA.
