And I might be able to make it run the result on the 6040, albeit slower because of the gantry weight. if I replace the spindle with an extruder assembly addressed as drive whatever. I'd have to rig a flat, levelable build platform and heat it too, but its doable, or I could probably drive the Ender-3 Pro with linucnc running on a pi4, its working really well on the Sheldon lathe. But that would be a hell of a lot of work I may not have heart enough to complete, they had to replace a 5 month old stent the last of May.
But before I can do that, slic3r needs to run on this machine and apt-get is refusing to install its gui's libwx-perl dependencies. Frustrated is not an adequate description. Complaining about broken dependencies but refusing to name the package thats breaking it. > On 7/19/20 5:19 PM, Gene Heskett wrote: > > On Saturday 18 July 2020 22:21:20 Gregg Eshelman via Emc-users wrote: > >> Circa 1990: Have you heard of the new Hubble Cocktail?
