I acquired a robo 3d r1+.. for free from a friend that was hardly used. I've used these forums extensively to troubleshoot the printer and I got it printing.. for a while. Now it'll stop extruding properly mid way through a print, could be 5 minutes, could be an hour. It'll just stop extruding and sometimes I will find a zig-zag like jam where the hex bolt feeds the filament into the extruder. I honestly think my issue is being ignorant and using matter control. I have been watching NoviceExpert's videos on youtube and other's along with reading other's issues on this forum(s). I honestly think I should switch to Cura but the version that is available is 2.5 and there aren't really any settings besides the older post from 2015. Which I think still translates the same. All in all I wanted to post and see if anyone has any references or direction to steer me to appropriately get my printer running. Thank you in advance.
