Junk driven by emc2/axis does the plotter dance!
Junk driven by emc2/axis does the plotter dance! Tube. Duration : 2.40 Mins.
IT IS ALIVE! x axis: epson scanner carriage and bipolar stepper, driven by A4983 y axis: star micronics matrix printer carriage, bipolar stepper, driven by A4983 z axis: sony cd-rom mechanism, cable and stepper motor, driven by L293D and an Arduino duemilanove. Home made breakout, Computer: salvaged P4 Compaq with 1 gig RAM that was being thrown out to the garbage Software: (No stinkin' windoze!) Ubuntu 8.04 RTAI from linuxcnc.org EMC2/axis runs as silk. Issues and lessons learned: the y/z carriage is a bit too heavy (iron construction angle) for the y stepper. The y stepper is too weak, lacks resolution and does not take up microstepping.The X axis for this one (the gantry) Built to learn about CNC and to explain geometry to da kid. @alteragnostik Still need to do the full writeup. Depends a lot on what you have at hand (or found in the garbage). I have posted some writeup and code for the pen holder, re-using old HP optodetectors her: korovievskitchen.blogspot.com The control software is EMC www.linuxcnc.org.
