First Layer has Lots of Gaps?
I've been having problems with my first layer. It sometimes ends up having gaps like in the pic. I've spent hours adjusting pressure advance, flow rate, and the z offset and I can't seem to get rid of it. I find because of this my first layer adhesion tends to be bad and it tends to lift up frequently. I didn't have this problem before.
Z-Banding V Minion
So I guess this is z banding. Anyone got an idea what I could do against it on my v minion.
Issues with “long blobs”
Hello, having some issues regarding what I believe to be extrusion. I’ve checked extruder esteps and everything is flawless. It extruder isn’t skipping. Additionally there appears to be a sort of “drift” along the X axis as the machine’s gantry seems to slightly layer shift to the right, leading to trapezoidal shapes.
V-minion z-wobble or banding
Hi all, I built a v-minion full kit from ratrig, everything was ok but when I tested it I found some z-wobble/banding, artifacts in Z axe (in my opinion). After that I try a lot of things, I try to give my best aligning the leadscrew with the pom nut and motor but the problem was still there, I replaced everything, the leadscrew, the coupler (spider and other types), even the stepper motor and the linear rail. I changed the pillow block printed part for another one...
The last thing I'm thinking about is about a skew error, something that is not 100% squared in the main frame, so I'm thinking about re-done everything again, even print all parts again.
In the other hand I have some mods that I've found here and around. Like double linear rail in Z with a new printed part instead of the one that I have that is metallic. I also saw a mod with a motor with leadscrew integrated like voron or prusa. I also see one that is using an oldham coupler instead of the pom t-nut....
Getting some ringing effect..HELP!
I am not able to get perfectly smooth prints even after input shaping
ASA overhang problems
I'm trying to print the decoupler mod for the motors, but I can't get this overhang right on my vminion. I tried to print it slower at around 50mm/s, but that did only improve it a bit.
Printed parts not aligning properly
Hi there,
I am currently in the process of reprinting all my v2.4 parts on my vcore 3.1
However I am running into this issue where the printed parts don't align properly like in the image

Calibration after upgrade
Hello guys,
I did the 3.1 upgrade and installed a rapido 2 on my v core 500.
However nothing comes out as it should....
Consistent 2mm Z banding. 3.1
I'm struggling to solve this Z banding. This test was with PLA @ .3mm height. Happens with or without infill or Arachne.
ripping/tearing of first few layers in one local spot on large print.
The first few layers ripped and teared in one local spot on a large print.
What might have been the cause and what can be done to fix it?...
Issue with overhang first layer and support bridging
I'm having some issues with overhangs as seen in the xyz cube, the first layer of the overhang for the "X" and "Y". I think it is a similar issue as the first layer that use supports also don't turn out great.
Overextrusion after internal top layers
Good afternoon, there is some serious problem with overextrusion of the upper layers using PrusaSlicer, in fact, as I understand it, the slicer makes a supposedly thick layer of infill, stretches bridges over the infill. With a layer of 0.2mm, the layer of bridges is 0.57mm, but the problem is that my layer is applied perfectly horizontally and without sagging. As a result, the next layer of solid filling is printed with overextrusion and this parameter accumulates.
The extruder is calibrated, the plastic is also normal....
Stringy prints
I have the 500x500 V-Core 3.1 (Enclosed), Bondtech LGX Lite, Rapido 2 UHF, 0.6mm Nozzle. We have been running MatterHackers Build PLA at 205/68. No adjustments to the speed on the SuperSlicer profile. Prints have a lot of stringing, spiderweb-like. We tried 1 mm/40 mm/s stock retraction settings, we are now at 10mm/40 mm/s. Any recommendations?
1st print great, 2nd print cracking/seperation
Any ideas on what might be happening here?
1st print went great.
2nd print there was layer separation ~3/4 through the print.
The separation happened 10 layers after a bridging routine. I have a 4028 fan.
I thought I had it turned down but looks like not. it's running 100%. Does the excessive airflow and small part size cause the separation?...
Strange Artifacts on First layer
Hi guys,
I have these strange artifacts during the First layer.
I clean the bed with isoprophilic alcool a lot and warm the bed at 65 degrees for 10-15 mins before launching the print.

Poor bridging on first solid top layer
I am having problems with poor bridging on the first solid top layer. For some reason the ends of the bridge do not want to attach to the inner perimeters. This poor surface results in getting a poor final top layer unless I add a whole bunch of extra top layers.
The example shown was done with Polyterra PLA printing at 205C. Bridging flow is 0.8 and speed is 70mm/s while most of my solid infill is at 200mm/s. Cooling is set at 100% for bridging and I am using a 4028 fan.
The filament was just received and freshly opened today....
