      Project 'Piranha' is a high-end CNC machine meant to serve anyone who has bigger requirements to stiffness than the V-wheel/V-slot linear guide system can deliver. The Piranha will be the ideal machine both for experienced user as well as the inexperienced enthusiasts. Piranha is a convenient tool that can help with small- to medium-sized wood, plastic or aluminum projects in your home or professional workshop. Easy to build and easy to use!

      The Piranha is equipped with strong 15mm linear guide rails and corresponding blocks. Mounted on strong C-Beam it will give the machine extra strength. Gantry plates are made in 6mm solid aluminum. The transmission will be all lead screw driven similar to LEAD 1515 machine.

      We plan to make three models: 1010, 1015 and 1515. The development work is a joint effort between makersupplies.dk and some interns from Copenhagen School of Design and Technology

      We now have a working prototype with all gantry plates milled in aluminum. Say Hello to the Piranha CNC :)



      The prototype is now ready and most/all details developed. One of the challenges has been to make spacers for the ACME Nut Blocks. In order for the lead screw to move freely all the way - it is critical that the spacer that lifts the ACME Nut Block is very accurate. For the prototype we tried 3D printing but it was not optimal, so we ended making them in ply wood. For the final kit we expect POM or aluminum.

      The machine is now ready for its first cut in MDF. We also made a nice spoil board for the machine.



      The digital files are now added to the project. You will find the full assembly in the file Assembly.STEP
      The main plates are made in 6mm aluminum sheet :
      Front and Back Corner Brackes. You need 4 of these. (F-B plate.STEP)
      Left and Right Y Gantry Plate (X-Y plate left.STEP & X-Y plate right.STEP)
      The X and Z Gantry Plate (X-Z plate.STEP)

      We have made two versions of the spacer between Gantry Plates and the ACME Nut. Both can be used but one is simpler to make. Suggested material is aluiminum or POM, alternatively a 3D Print:
      Spacer with two rings that fit into the ACME Nut (Spacer 1.STEP)
      Spacer with flat surface (Spacer 2.STEP)

      The file MiniSLDPRT.STEP is a small bracket to mount the limit switsh to the Z-axis. This part can be laser cut in 6mm acrylic or 3D Printed.

      Two files should be 3D Printed to make some Drac Chain Holders for Y and Z
      (Y drag chain bracket.STEP & Z drag chain bracket.STEP)

      During assembly you nedd to allign the Linear Rail wit hthe C-Beam V-slot. To make that easy to need two pieces of the Rail Spacer made in aluminum (Rail Spacer v1.STEP)



      To be continued …….
