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.

i put the back feet entirely in and raise the front to get it pretty close to level again. its just slightly off but i wanted to see if it impacted the back corner at all, which it didnt seem to
since the full adjustment didnt move that corner im wondering if its actually a gantry squareness issue
Let me help you 😄
Can you redo the bed mesh and send me the image, and please do not rotate the screen
I did notice my x gantry was off again right before heading to bed so I'm betting that's going to improve it a lot
i did some small adjustments to the gantries. here's before calibration
looks like that made it slightly worse at .528 now
Lets go out of the lates one.
In this case let first fix the back.
Your rear left corner is going downwards, which means you need to push the back corner slightly down, or rise your front left upwards.
In case of the V core 4, it is recommended to only touch the back, so I suggest lowering your BACK LEFT Corner, down.
Don't mind the x that is bent
You just want the back 2 corners to be at the same levle.
This has to be flat
Left corner and back, no matter if it goes sloped.
We'll figure that once you solve this.
Wait that's my back left corner??
My basement is slightly sloped from back to front.
Doesn't matter really as this is all in reference to you printer.
Just got home from a quick playground trip so I'm raising and recalibrating now
.297 now which is halfway better than it was before. i thought i was supposed to be lining the mesh up with the opaque plate though. am i wrong in that interpretation?
maybe too much now given its .432. Edit: after posting the ss i went and measured my gantry a couple times and found it a couple mm off from each other. ive corrected it to be within 1mm on each side.
Only fix the back first
So left and right
Ignore the variance
You want to align first the back cornere.
Corners*
After left and right back is the same
Send it again here.
getting there
Yeah but you are back in this image where you were. It doesn't matter that the back is not on the white board atm you first want to alight the back corners so if both is for instance - 0.2 that is fine if they are the same. Because then we can fix the x and you are done.
ahh i still was thinking about this wrong clearly
so i need to raise the back left up a good bit then, correct?
After each adjustment are you releveling the bed and redoing z?
yeah ive been doing a home all each time. maybe thats not doing what im thinking though as it already knows where home is on all 3 axis?
@chicken
carrying over the short convo from #v-core-4
I don’t know if homing z-tilts. Not at home currently so I cannot test. Make sure to z-tilt after each adjustment you make. If adjusting the feet, make sure the nut on the feet is tight against the frame as that can cause some rattles later on during shaper tuning
yeah i tilt every time as well. will double check the nuts
This one does not look like z tilt was done
Those three points should be level and they don’t look like it
Front right looks near 0, back middle looks a little down then front left is further down
Z tilt makes sure those are level
nuts were definitely in the wrong position. hmm i promise ive been hitting the z-tilt button every foot adjustment made based on the comment you mentioned last week
since i just adjusted the back left and tightened all the nuts im running homing and tilt again
Be back in a few. Packing for a trip
purposefully moved the bed down to force a rehome. it stopped at 15 during the homing but tilt has it at 20. recalibrating
wow literally no change even though i raised the back left up a lot
wouldnt you wanna push the back left down?
Ratos is fully patches?
since its further away
yep. im a cyber security engineer so im a heavy advocate of patch quickly lol
oh did i do the direction wrong? lol
i believ so. Since the bed is the one that moves its counterintuitive
ok just inverted that. running the whole gambit of homing again
ok now thats more wacked out lol
the back at least went in the right direction though!
left front view
yeah now the back right is too far
so you can move the left one a tad bit further then the back right one closer
so that guy needs to go up then to balance it out
cause thats inversed of what the graph shows
this one just finished after trying to dial that in before. maybe i didnt go far enough on the back right
back right needs to go closer to bed not further
right so that means put the foot higher in, towards the frame, correct? idk why its hard for me to grasp simpler concepts like this lol
youre good it took me a while for it to click lol
wait so did you make sure the frame was level by moving the feet before messing with the gantry?
the frame used to be level based on a 1m long spirit level i had used to ensure it was based on the feet adjustments. im on a slightly declining slope though due to an older house that used grading to run water towards the sump pump
Y is way out of level now though. X is almost perfectly in the middle
thats after you adjusted the feet to try and fix the bed mesh right?
correct
i also remeasured the x gantry to ensure it was within 1mm of each side. it was 3mm beforehand but that was fixed this morning
tbh i would go put the feet back to make sure the machine is level then mess with the gantry.
the bigger machines are a pain to get a flat mesh i feel like
heh im feeling that lol
i got it close on my 400 and let bed mesh do the rest lol
just wait until you get a ti gantry and want to shim it:kekw:
heh. i said id order that later as i just want a functional printer to start off with and have blown the budget already with all the extra parts and a couple new tools/accesories to put it together
thats also why my electrical isnt looking better lol
ok so to level this off again i have to severly lower the front feet or severly raise the back
Front right*
thats what I did then in about a month I ordered everything you can for it ;-; my wallet hurts lol. Now im messing with getting box turtle set up.
to counteract the gradiant of your floor right?
correct. i leveled all top extrusions off to be as close to center/perfectly level as possible then locked in the nuts. its halfway done with the heightmap now
moved all the axis and rehomed, retilted ofc
sounds good. I just wanted to make sure I was on the same page as you lol
well thats odd
maybe its a gantry issue again?
left front
the one thats super far away is back right>
yeah it always starts off that way for me. idk why
maybe the back right corner of the frame isnt fully square since the rest of the frame is showing pretty close to level
I would push that corner closer to the bed then
This is the back extrusion x axis fwiw
i think i went the wrong way 🤦
almost there now it seems
in the right direction now. .396 but the back needs to come up a little more. its a bit less than the last time
That’s good. Any progress is good progress
I think the rule of them if your machine is X00 then anything under .X00 is fine. Unless you want it better then go for it lol
this back corner has to come up a good bit first
im nearly happy with the front right now too but my range is .479 now so i probably did the wrong way again
i extended the back right to bring the bed up more
last one of the night for me though since the kids have been waking up earlier 😐
yup... .9 🤦
hallelujah
blue == foot up; red == foot down
wait so is that the corner thats far away now?
Folks
Hahaha what is going on I was just away for a short while.
You can't fix anything proper if you do not allign the back furthest point left and right.
Front left and righ twill always have 2 points that are flat due to z tilt.
Ie this bed is great
Like this
Because all he has to do in this case is LIFT with his hand the middle of X upwards.
That is it.
What you have is a severly titled bed.
not sure i follow now that im back and able to work for a bit. what do i need to lift here? also my back left foot is really cranked up in the extrusion so i cant go much farther. as ive said before, the floor is slanted towards te sump pump from the back feet to front on the Y axis with the back being the higher grade so, yes, im starting with a tilted bed which is why its more challenging for me to get right
if i was on a level floor this probably wouldnt be so hard and id be past this already 😭
almost there...
That’s the best you’ve gotten it right?
so far yeah. im out of room on the back left though so i might have to shim it a bit
i do plan on some full bed prints so i want to ensure i have the back corners usable
what do you recommend for the back left since im out of room on the footings? do you think a .2mm printed shim will help?
@chicken would love your thoughts too given you practically know my printer with how much help you've been with the setup 😂
oh here we go! front right first ss and second is back left
How screwed in are the washed the 4 feet? I would normally recommend to follow the commissioning guide and move the extrusions a little to get things close then fine tune with the feet
The back left is all the way screwed in, can't it get it more hand tight. The washer barely moved before having to lock it in
Your less than 0.2mm on a 500mm bed? Not going to get much better than that.
That’s mine after a heat soak. Still prints fine.
Woooow that is a huge bend!
That’s the bimetal effect
I have the titanium gantry just not had time to install it yet.
This is also without the plate on btw since the guide does have the note it shouldn't have the heater or plate yet
Klipper can deal with a lot. Where the issue is that the movement is not stable and keeps moving as it warms up
Good to know
For sure. Make sure everything is good before you install either
Less than 0.2mm is awesome on a 500mm bed. Not going to get any better than that
sweet. i wasnt sure if id ever be satisfied or learn to be cause im ofc going to be OCD on getting it as near perfect as possible. probably going to end up running this calibrations a lot anyway when starting off just out of paranoia
Thanks for the help here everyone!
