1515 Printer slides

thingiverse

These are printed slides for the mini Kossel printer. The original idea came from Bill Plemmons (http://www.flickr.com/photos/92732833@N04/9940136066/). The scad file uses the fillets openscad library (https://github.com/StephS/i2_xends/blob/master/inc/fillets.scad). I am using them without the nylon screws, but the holes are there for it. Instructions I printed these on a mini Kossel and you need a printer that is well-tuned to print these. As such, the tolerances are very tight. I use a length of extrusion to manually "burn-in" a newly printed slider. the friction softens the plastic a bit and smooths the feel. I then use a gcode program to "burn-in" the slider starting at 50mm/s and working up to 400mm/s. I have to run the printer as a Cartesian to get these speeds. I don't use the 3mm nylon screws Bill uses. I found they add squeak. I have run these at over 600mm/s (https://www.youtube.com/watch?v=DABFczCJ2QI). Time will tell if these are viable, but my accelerated testing says they will be.
