ToolHead Front Printing

Hole Tolerance

I've had my v-core 3 for a while now but one issue I've been battling with from day 1 is horrible hole tolerances. Clearance test prints seize up with anything below 0.3mm tolerance and if the holes are very small it gets even worse. Outside dimensions are spot-on on all axes. I understand that XY compensation is a way of addressing this, but a) unfortunately PrusaSlicer doesn't allow setting that separately for holes and b) my Prusa achieves much tighter tolerances without such adjustments, so...

esun epa cf Problem

Hello, I have an issue with my 3D printing. It only occurs with the EPA CF material; all other 3D print results are error-free. I’ve already adjusted the flow rate, but the problem keeps happening at regular intervals. What could I try to resolve it?

Best back_core_xy part orientation and sticking advice? Constant curl upwards on 'top' two corners.

Anyone know if there is a better way to orient the "back_core_xy" EVA3 hotend part other than flat (with the side that ultimately faces the front of the printer facing down)? Try as I might, I absolutely cannot get the two topmost corners of this part to not curl up from my PEI spring steel during the print with this Hatchbox ABS I have. I've tried printing enclosed, tried wider (~.5mm) as well as taller (~.3mm) first layers, tried setting both extremely low as well as more normal z-offsets to really "smush" the filament in, tried an older as well as a brand new PEI spring steel plate (two different manufacturers), tried multiple bed adhesives, tried bed temps of 90, 115, and everywhere in between...and no matter what those two corners just like to pull upwards even though the rest of the part sticks just fine. Anyone have any thoughts here on anything else I can try? The only thing I can think of that I haven't tried yet (will tonight or tomorrow) is printing with a brim...but man this one is kicking me and with every other thing I've tried above having made literally zero difference for better or worse that I'm struggling to believe a brim alone will be the fix. I also am having trouble understanding (from a printing mechanics perspective) what exactly makes these two corners be so evil to me lol. Any insight would be greatly appreciated!...

Switched to 0.6mm nozzle, rough time of calibration

I put in the 0.6mm nozzle that comes with the Rapido 2 and I'm trying to calibrate everything. I'm hitting some problems that I can't seem to figure out, though. Anyone have any thoughts/tips/0.6 profiles? - Red: This is the edge that the z-seam is on. It seems to have a chunk out of it. I have tried to calibrate the Pressure Advance. The other corners seem fine, just the one with the seam. It's currently set at 0.017 (it is 0.025 for my 0.4 mm nozzle). - Yellow: The edges don't appear to be straight. There's a bulge in the middle, most visible on the corners. I've tried messing with the extrusion percentage and the line widths, but it doesn't seem to completely go away. - Green: There are some small gaps between the top infill and the perimeters. If I bump the extrusion up enough, those close up, but then the surface on the top is rough due to being over-extruded....

over extrusion and under extrusion on the same print

Hi all, I have a print that on one side is over extruding almost to the point of failing and on the other side has areas that don't have enough extrusion. Seems like too much plastic on one side of the print and not enough on the other. ...

Inconsistent First Layers vcore 3.1 w .6mm nozzle

I did the first layer test print yesterday after calibrating the probe offset. I eventually adjusted the z offset until the top surface of the first layer test was very smooth, let the print complete, and saved the adjustment to the config. Today I went to print a calibration cube, and the skirt and outer perimeters of the cube's first layer printed horribly. About halfway through the solid infill portion of the first layer it suddenly turned smooth again and the print completed properly. Attach...

Second Hand 3.1 with 0.8mm Nozzle not printing

Hello everyone its me again! I hope this saga has almost come to an end! So after finding out that the printer does not have its standard 0.4mm nozzle but a 0.8mm nozzle instead. The test extrude function works fine but when it comes to printing the gcode the filament just balls up next to the nozzle.

Warping at support interface on large print

Gaps at end of perimeter

My print experiences gaps at the end of external perimeters. It appears to line up with my seams and retractions, however it does not go away if I disable retractions (set retraction_length to 0 in Klipper. I have firmware retraction on). I use Superslicer. I have seam_gap[0] = nil any pointers in the right direction are greatly appreciated....

Nylon cf-15

The filament is being actively dried. Although how dry it currently is. Could be up for question. What would your bear guess be this is? I have not tried anything yet as I’m not much of a print quality person. But I would like this gone.

First Layer defects

Hello all, Could use some advice on my first layer. Getting these "boogers" on top of my first layer and can't figure out what's causing it. It's sticking up high enough the nozzle runs into it and potentially causes a layer shift Printing PETG at 235C with a Mosquito hot end and Orbiter extruder. I have gone through calibrating my motor for the extruder already...
