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?...
fixing a twisted frame that doesn't budge - Vcore 3.1 300

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...

Anyone have any ideas? Please note that the magnetic plate is installed.
V-Core 1.3 500
Should I just live with this or can anything be done? I think a little bit of this is the gantry sagging:
Max [168.3, 20.0] 0.229 mm
Min [465.0, 240.0] -0.454 mm
Range 0.683 mm...
VC4 500 IDEX
I am trying to get my bed as flat as possible. After working on both corners this is my best try at this moment. Is this ok for a 500 IDEX or does anyone have tips to achieve a better result? Heightmap is generated with a cold bed, probe is a beacon.
Bed bowed along Y axis
I followed the general advice to adjust the gantry and achieved a consistent level at the corners of the bed mesh. However, the Y axis looks very bowed. I have not yet put the PEI sheet onto the bed, so the meshes seen are of just the bare metal bed. Heat pad is not installed.
* I tried loosening the Y axis rails and re-tightening them from the middles outwards.
* I tried the same thing, but with 15 lb weights on top of the Y-axis extrusions as I re-tightened the rails; no discernable change at all.

vc 3.1 500 mesh is a hell
hi guys, i'm still having problems with my mesh, i'm using a superpinda, can anyone help me?
it's a cold bed...
VC500Idex bad mesh
Hi folks. First of all I have to say, that I was not able to do the initial bed mesh without the heater and magnetic tape, because I bought the bed plate used allready with heater and magnetic sheet attached.
So I assembled the whole printer and did the mesh leveling with heater and sheet allready attached, but the result is pretty bad, as you can see in the screenshot.
I tried to optimize, but I am struggeling a bit with that. For example, I lowered the back left joint of the frame nearly 3mm, but the result of the bed mesh was decreasing just by 0,15mm or so....
