      z axis notes from other builds

      The Z axis is purchased with the control package from each company. Both use a
      16mm ballscrew and linear rail. The Bladerunner uses 20mm chrome hardened
      shafting with recirculating ball sleeve bearing where the Spark Robotic uses 20mm
      profile rail with recirculating ball bearing blocks. The torch mount on the Bladerunner is
      rigid or option magnetic breakaway where the Spark Robotic Z axis uses a collision
      detection torch mount with proximity sensors.

      Tourch height control

      software only THC has advantages and disadvantages. It’s cheap but not as fast and has to share main processor cycles with the OS and CNC control software
