Homemade linear delta-robot, really tripod cnc robot, another rep-rap. Experimental construction driven stepper motors.

Linear sliders PTFE self-adhesive foil lined, this is very good. RC modell joints. Workspace d 120x160mm. EMC2 is working very well! I have edited new kinematic file in "c". Machine have x, y, z axis and A axis for extruder of RepRap application. Max feed-rate

2400mm/min, this larger motors can be more. Joystick control configured in EMC2.

  • The sliders are minimal backlash. However, the threaded nut and screw threads between backlash. This eliminates most of the weight of the structure.

    Could do with teflon threaded nut.

    greeting

  • Thank you for your interest. This project is now

    suspended. If you have a question I will try to answer.

    I will soon upload the kinematic file. Greeting

  • I used a version of your test pattern in my latest robot. Thank you for being such an awesome inspiration!

  • @hg5bsd very interesting project, i want to start with building up a similar maschine like yours, but software issues are difficult to me, my question: could you send me the kinematic file and an instruction how to implement it in emc2

  • mi potresti mandare anche lo schema di collegamento per favore?

  • Not a good idea to apply stepper motors when payloads can change unless you have sensors on each axis.

  • I like the drive mechanism that you're using. It seems like it would be immune to backlash issues as long as the vertical sliders (I don't know what else to call them) are heavy enough.

    Was backlash a problem?

  • Top stuff! Very Impressive! Keep up the good work!

  • This thing is so boss,  I gotta make one.
