Strange Peaks in Mesh
I just got back home from a vacation and now my bed meshes are looking strange not sure what happened but there are now 'peaks' in the mesh that when trying to print are causing the nozzle to be to high off the bed.
Solution:
Figured out some parts I printed with embedded magnets caused this issue, currently working on demagnetizing the bed
bedmesh not applying at all for first layer?
My company bought the idex vcore 4 500 to prototype large parts, but suddenly it does not want to use the mesh when doing first layers.
it probes before ach print but no matter if i do small or large prints that spann the entire bed. when i did a 400x400 1 layer test i had to turn flowrate down to 80%, it unmderextruded where my blue sides are on the bed and overextruded in the middle. were having huge problems with general bad extrusion as well..
Any insight would be extremely valueable. its all stock ratrig, using newest prusaslicer profiles for 0.6mm. The printed worked fine in the beginning but now almost all aspects of quality seem to degrade....
Help with initial mesh setup
hey folks
i´m building a vcore 4 500 with idex. tried to tab down the back corners which helped a little. the warping along x axis did not dissapear. saved the config, homed the machine and did a z-tilt routine. after that the mesh scan looks like in the beginning.
i have a machine with a back plate mounted already. should i unbolt that to get to the screws on the back of the frame? however, there is a middle post holding the whole back secion up. in order to lower the frame it would be necessary to cut this one shorter....
Strange Looking Mesh (brand new V-Core 4 400 build)
Does anyone know what could be causing this strange "S" curve in my mesh? I have tried adjusting the screws at the back corners of my frame, and I have closed the gap a bit, but the entire mesh seems to be maintaining this shape and moving upwards into the red direction at this point.
Trying to sort out taco bed on 400mm VC4
I am trying to figure out where to start on this one. First I thought it might be an Y axis issue but honestly I am getting a bit stumped.
Using a Ti gantry...
Solution:
I went ahead and shimmed the y rails as in the end it was them or the y gantry dipping downwards.
VC4 beginners mesh
Hello, I’ve just got a new V-Core. I did a mesh and got this result — I need to raise the back left corner. I tried loosening the screws as shown in the photo and lifting it, but it doesn’t work. The mesh still looks the same. Are these the correct screws? Thanks for the advice.
Solution:
What i found useful was using a straight edge and make a mark with a pencil across the gantry and corner post so i could "see" how much i adjusted it. Remove the enclosure side completely then make that mark, loosen the screws and lower that corner slightly. If nothing is changing you aren't moving it
VC3.1 heightmap inverted?
Whenever I look at my height map and the print itself, it seems like the height map is inverted.. (or atleast the Z axis is). In this example, the heightmap shows the highest point at the left side [175.6, 304.9] and the lowest on the right. But when I'm printing it seems that the lowest spot is on the left and the highest on the right. Is there any way to fix this or am I just misinterpreting it all?
VC4 500 IDEX - Need help for bed mesh during commissioning
Hey guys,
I have finished the mechanical and electronics build of my VC4 500mm IXED machine recently and started to get into commissioning in order to start printing asap.
Unfortunately, I've been dealing with some struggle with bed mesh and I can't get better results than this. My C and D points are as low as they can be without forcing too much on machine's structure. I did my best to make put them at the same level watching at the mesh. I still have this kind of taco shape that makes me think that my X and Y got some bending issues.
At the end of the day, this still represents a .4mm difference within 500x500, but I really don't know if this can be handled easily or not with klipper + beacon later on, knowing that this is based on the aluminum plate and not PEI plate which can also lead to some deviations probably.

VC4 500 IDEX weird wavy bed mesh
Hi there! I just finished assembly of my new printer and it puzzles me. Here's the bed mesh I'm getting. This mesh has min of -0.365 mm and max of 0.076 mm (0.441 mm range), which I consider to be pretty good for a 500x500 bed.
I'm not new to the 3D printing - my first machine was Reprap Mendel, then a few others, and now I have a Voron 2.4 as a main one. So it's fair to say I have a bit of experience. 🙂 However, I have no idea where this wavy pattern is coming from.
I checked the bed with a straight edge and a feeler gauge - it is fairly flat but is dished in the middle. Not much of a dish though - under 0.05 mm in all directions except the 0,0 to 500,500 diagonal where it is under 0.1 mm. Now given the bed is flat, my thoughts are:
...
Assistance with my bed mesh pls.
Here I thought I would suffer the most on the electronics build of this printer and fortunately nothing got fried 🙂 Now I'm trying to figure out the bedmesh and from what I've been reading, I need to loosen the bolts and either give it a whack up or down to adjust? Do I need to loosen both of these? From what I can tell, I need to lift the right back side and lower the left back side?
Appreciate your expertise 🙂...
Solution:1.5 delta isn't that bad on a 500. I only got my 400 down to 0.100. Adjust your Scale z-max all the way right to make it not look worse than it really is. Looks like you do have room for improvement in the back right corner. Right back tap it down, Left tap it up if the right doesn't level it out. Make small adjustments and re-mesh, one side at a time.
You only need to loosen the bolts for extrusions the motors attach to, each corner has two bolts. Shouldn't need to adjust the top. The commissioning guide gives a decent explanation on it....
Upgraded Vcore 3.1 to Enclosed - Bed is looking... bad!
Hey all
I recently upgraded my RR 3.1 to an enclosed version (without the perspex for now) and the bed mesh looks utterly awful. I'm using a Beacon (latest version)
Any advise where to start with this one? As it's got the enclosed frame now - what's the best method for squaring this up? ...
Can someone help me? How can I improve my mesh in the corner?
I'm callibrating my V-Core 4 500, and I can't make these corners up. Any suggestions about how to improve my mesh? Thank you in advance. The corners looks to be in the back.
Solution:
Problem solved! I redid it after closing the 3D printer. Also I'm doing different meshes for different temperatures.
To recap: pushing gantry helped a lot. Also adjusting the back corners, and playing with the rubber legs too....
strange work of adaptive mesh
ji guys! I have a lot of problems with the first layer. this is my bed mesh with cold plate.
i have have the super panda, I have big problems with the offset calibration because I use the probe_calibrate with a 0,1mm metal sheet (obviously with hot nozzle and plate), so I start the print, it start good but after some lines the nozzle is too close from the plate, so I move mualually the offset and some lines later the nozzle is too close again. if I stop and restart the print the offset is fucked. pleas help me because my brain is exploding...
Front of bed higher then back
I recently noticed the front two z rail extrusions had come a bit loose after around 1700 hrs of print time so I took the side panels off and tightened them. Ever since doing so I noticed my bed meshes are higher in the front of the bed then the rear. Any ideas on what I can do to fix this?
Solution:
This is normal as your X axis goes down with time/temperature. Making this taco shape that goes sloped down.
As when your X is sagging downwards, like in here, the REAR z tilt will go slightly down to compensate so the triangle is flat (the 3 points of z tilt). Making the appearance as if your Y rails are going downwards while, in reality they are not....
Commissioning Guide Help
I cant seem to get this back corner to raise up at all. I suspect it might be a frame issue but can someone confirm? I've confirmed the frame is standing pretty level on the X and Y with a meter long level that I use around the house so I'm a bit confused. Two of the feet are mostly out of the threads at this point though since the floor is sloped towards the sump pump.
Vcore 4 Hybrid 400 Comissioning bed mesh
So, this is my first try after comissioning, the D corner seems to be a lot higher so I am guessing I need to fix this?
I am reading the guide but I cannot wrap my head around how to adjust it, I don't understand what I need to loosen and hit slightly?...

Hi! first of all, I've watched this famous video about the topic: I'm trying to fix a slightly twisted frame on my printer, and considering what's in the video and my current mesh I tried doing the following:
1- tapping on A to push it down
2- trying to push B up...
