globs and bubbles everywhere
Posted: Tue Dec 23, 2014 4:46 pm
So here's my back story. I got the RostockMax V1 almost two years ago and I built it and got it printing really nice. Then I got cocky and starting tweaking left and right, changing settings left and right. then one day it just stopped being able to extrude during a print. It would extrude filament just fine but when I went to print it would stop working. I cleaned and checked everything mechanical. I verified temps, replaced gears, adjusted the extruder steps and no luck. So It sat there collecting dust because I was lazy and I had 4 other printers also in use so I was in no real rush. Well I decided it had collected dust long enough and it deserved to live. So I upgraded the firmware from .80 to .91 and starting going through my EEPROM settings and getting everything back to as close to default as possible and the same problem starting happening again. It took awhile but somewhere along the line I set retraction to 6mm which is way too much. Boom! I changed it to 3mm and what do you know it starts printing again but with globs all over the print. I feel like I've gone through all the EEPROM settings and configured everything back to default. This print is a simple vase using the vase setting in mattercontrol with zero infill. I'm printing at 210c and 80mm. I've lubes the filament with some vegetable oil and replace the PTFE tubing and it doesn't slip at all. I've attached a screenshot of all the settings. I'm running fully stock configuration, extruder,RAMBo. I'm using PLA so I expect some stringing but the globs should not be there. Any thoughts?
