    Cool MY T-SLOT MACHINES: CNC ROUTER AND FOAM CUTTER

    I have always liked the practicality of the extruded aluminum. Very easy to build machines from the ground.

    My last router was inspired by the Shopbot Desktop: I wanted something to be sturdy like a tank within a small form factor. It uses Leadshine drivers integrated into the machine body along with all the electronics. The ESS for the train pulse generator and a 1hp spindle form UGRA (first time to use a spindle, I was using a Bosch router and a super PID and i will never come back).

    All the frame was built using extruded aluminum.

    All the ballscrews are from ebay (linearmotionberings)

    Just like the shopbot, the first proyect was to make a spoilboard and a magnetic dust shoe

    So far so good, I been cutting aluminum very easely, just had to add some coolant, a choose the MD-1200 Microdrop.



    Currently im concerned about Mach3, i have read that a lot of people are switching to UCCNC, what do you guys think about it??

    My last build is a foam cutter, and again i built it with 20 mm extruded aluminum, currently im working to improve the cutting speed and the cutting temperature, trying to add a PID controller, I'm looking for the right thermocouple, any suggestions?

    Im using it with Simplify3d to control it, this foam cutter is powered by the smoothieboard.

    What kind of tolerances could you hit with with this machine cutting aluminum?

    Thanks for posting this. I'm designing a similar but smaller machine that is built in similar way with extrusions and linear guides / ball screws. Hoping I can get similar cut rates and quality to yours when cutting aluminum. I found your blog and also thought that was good resource.

    What stepper size / torque did you use?
    Are you using the 800W spindle you showed in the blog in that video?

    Thanks!
    -Todd
