Slic3r 1.2.7 seems to slice it fine, maybe you're running on an older version that does it differently? I do notice that it does a thicker inner perimeter for the bridging section though.by blt3dp - Printing

Your corners definitely appear to be bulging. I'd adjust the XY Jerk to 10, that's quite a bit of mass for an instantaneous change. Wonder if those bottom layers are bulging out because they're the base of the object, and those first so many layers the infill is allowed to reach a higher speed, maybe it's pushing the perimeter out? I've made this part, attached below that might test that. Oby blt3dp - Reprappers
Direct Drive 3mm don't really exist cause they can't really handle 3mm filament, it takes alot of torque. You need some gearing to provide enough torque, by means of a geared stepper or the extruder design like the E3D Titan or Wade's Accessible Extruder. Plus, you need to support flexible filament through the entrire path to the nozzle, the MK8 style Direct Drive Extruders usally have a gap beby blt3dp - Prusa i3 and variants

Hrmm, that's an interesting design. There are no vertical supports, looks like they rely on the smooth rod. I wouldn't think that'd be rigid. Either way, things to check: 1. Those vertical rods are 90 degrees to the bed. Center of bed, base of smooth rod, some distance up the smooth rod would be your triangle points 2. Hopefully none of your towers are rotated.

QuoteTrakyan Originally I was planning to use one motor spin a gear and have all the axis and extruder engage and disengage from this gear (with a forward and reverse gearing). This saves on the cost of motors but I'm wondering if its really worth it. If nothing else it'll be interesting. I wouldn't think that'd work cause you need to move individual motors simultaneously different amounts. Nemby blt3dp - Reprappers
Also read that I should remove LED2, LED3, LED4 or replace their resistors to an appropriate value. But it doesn't mention LED1. LED1 looks different, like it's receiving power from the Arduino. Any ideas on that?by blt3dp - RAMPS Electronics
That makes sense, that's why they say 12V-35V output in the documentation. Say what Automotive Fuses though? Looks like exist 32V 10A and 5A fuses. I know for sure there are better things than RAMPS I already have it though. I'm definitely getting a Duet WiFi for my new machine. But for this old Prusa i2, RAMPS should do.

I can't say it was all me. I dunno, SketchUp does some wierd stuff. I'll never understand why I can draw a cube, and then a cylinder intersecting it. Intersect the face of the cube with the cylinder and all of a sudden the top of the cube drops triangles because SketchUp for some reason did it's little snap to thing as it intersected and now stuff's out of plane.

What nozzle size and layer height are you using? Someone double check my math. but: 208mm/sec * .40mm (nozzle size) * .30 (layer height) = 24.96mm^3/sec Which should be close to the theoretical maximum the volcano can do Your Volcano should be able to keep up going at 100 Unless you're going with bigger nozzle sizes and layer heights For example 100mm/sec * 1.00mm (nozzle size) * .80 (layer hby blt3dp - CoreXY Machines
I've designed this part, well modified this part in sketchup cause I didn't wanna redraw it in a cad program. It's got a few legs drawn on it so that it doesn't have to bridge a large distance.

Quotethe_digital_dentist What size nozzle are you using? 0.67 mm line width seems a little too wide for a 0.4 mm nozzle to me. I'm curious about this myself. I've used Slic3r for years with a .4 nozzle. I've never touched extrusion width and it's also .67 for me. It's automatically setting that on it's own so I figure there's some type of math involved based off of some assumption. I seeby blt3dp - Printing
The PTFE tube goes past the coupling into the heatsink a bit and stops far before the transition to the heatbreak. Take a look at the drawing. Looks like the throat screws in 18mm, then there's 12 mm before you see the filament entry from the coupler. E3D v6 3mm Bowden Drawing It's all M6 btw. The reason PTFE can go all the way down in the 1.75mm version is because the M6 stock is able to beby blt3dp - Reprappers

Aside from the one between the pneumatic fitting and the heatsink, I would think that your only transitions would be from the heatsink to the heatbreak and between the heatbreak and the nozzle. Possibly due to poorly drilled heatbreak or nozzle. You may be able to get around one of them by adding a chamfer on the top end of the heatbreak that way there isn't a lip of any type for filament to caby blt3dp - Reprappers
I have a question. You're using an official (not knock off) e3d aluminum heatsink? I ask because their 3mm bowden or direct version doesn't appear to be designed to allow use of a threaded pneumatic fitting. On the direct version, the inlet has a chamfer to guide the filament. On the bowden version they use an embeded pneumatic coupler. They put a chamfer at every transition to guide the filby blt3dp - Reprappers

Send M503 to see if it's actually using the steps per mm you're telling it. It's possible that even though you've flashed 1600, that it's still using 400 from EEPROM. If it's still using 400, send: M502 to load hardcoded defaults (the ones in your configuration file) M500 to save those settings to EEPROM Then do M503 againby blt3dp - CoreXY Machines
I don't believe we do the single wall print+adjust flow rate to get rid of the lobes rather than to make sure they're the right size. I think we're going off of the assumption that the slicer is doing the math properly, displaying what the expected outcome is in the gcode file (Slic3r for example), and then adjusting our machines to achieve that. Again using Slic3r as an example, the developerby blt3dp - General
I get that when my first layer height isn't exactly right. PETG likes to ooze and it seems to deposit a thicker layer than other filaments on the first. My nozzle would slightly drag over it and pick some up and do the same thing you're describing.by blt3dp - Printing
I'm still running with a Prusa Mendel i2 from years ago, the frame rigidity is trash. The triangles are good for direction in the Y direction, but it's rectangular in the X direction and there's no cross bracing so when the carriage moves, it wiggles, even printing slow at 30mm it wiggles enough to cause layer alignment issues.
