Shoot. Firmware restart turns off debug. Let me run this again....
Console for this log
this error is coming from the new sanity check that makes sure not to kill your build plate
this error happens when you try to make any VAOC calibration but the toolhead is not on the correct VAOC y coordinate
its a safety measurement
i think there was a bug in the VAOC code. IF you have changed the nozzle alignment and run z calibration without prior changing the nttols it can lead to this messsage
just pushged a bugfix for that usecase
That would still fail in this case. I believe the mismatch is because of things like skew_correction.
they won't be equal in that case as you're checking for now
VAOC is calibrated without skew calibration loaded
well, there was really a bug that i have fixed as i described
So the coordinates are different
yes i saw that, but it introduced another one š
if you start the z calibraiton without tany potential new control point coordinates have been saved it threw that error
how?
skew
so you mean i need to check the gcode coordinates?
or better said check the offsets
Yeah or allow a tolerance like it did before (just maybe not 5mm).
well before id didnt allowed any tolerance
š
If you check the requested gcode position instead of actual position it should be equal
there is still a issue with thsi approach
It did, just only in one direction š
we need to work with a tolerance, we cant use exact coordinates since we cant be sure if any new coordinates have been tuned but not saved
and we cant save them in this situation
i almost pushed a wrong update which could have lead to a catastrophy
thats the result of removing the save button from the UI :kekw:
all good to keep waiting
or try the new fix?
Your issue seems to stem from skew correction, if you load your skew profile before calibrating VAOC, then clear it when you're done, your problem should be gone. The current code should work without it though (if you haven't updated since your last message, do it now)
there doesn't seem to be an update pushed. version is still the same as when this was happening RC3-65
I dont have a skew profile....so.....not sure how to load tht.
or you mean input shaper?
should i set that to 0?
Huh... Then i'm not sure how you're getting the error you're getting. There's some kind of x/y compensation going on.
You're right, i forgot we didn't publish it yet, it still needs testing
any progress on this?
or ideas for a fix?
we have already a fix but it isnt merged yet
there are other things that we need to test first, we are making some changes to the post processor as well
sorry to be a hassle. no rush. just was wondering.
but if you want you can test it by switching to the development branch
all good, i'll wait for the update. working on CAD in the meantime, was multi-tasking before. Pretty sure the printer is almost ready for game-time. just need this done, and then enclosure, replacement parts from rat rig that were damaged
great

tune your endstop positions according to the commissioning guide
hmm, this is new
ok
ill ahve to go through it
so, doing the commissioning guide leads to my "max endstop" being lower than it's actual physical value.
"tuning" them leads to this error upon homing:

because the new values recommended by the calculator are lower than that
before doing a new endstop calibration you need to reset the current toolhead offsets with
_VAOC_RESETah, ok. that's probably it. i did see that there was an x offset being applied
wait, so start over that section from scratch now after doing the reset then?
when doing the endstop calibration you need to make sure that the system hasnt applied any toolhead offsets
1.
_VAOC_RESET
2. endstop calibraiotn
3. VAOC calibrationSo, i did the endstop tuning, and still ended up with this
idex_xoffset = -3.634339009393699
both my nozzles are at the edge of the bed when set to x 15 and x -15 for t0 and t1, respectively
at Y = 250, though the guide doesnt specify which Y the tuning should be done at.
If i move to Y= 10, they are off, and if I move to Y=500, they are off again, almost as if my bed is not square
This shows going from 500 to 0 and then back to 250
hmm.
this means my z-rear extrusion is not in the right place, doesn't it. fuck me.
how could it be off by so much? z rear motor works fine and is lined up
Looks centered
Looks angled when viewing vaoc
there is a slight rotation on the rear z extrusion...maybe 2-3 degrees at most.....skewing the whole bed slightly on Y and due to the size of the bed...means there's about 6-7mm of variance on x when moving from front to back.....ha....im going to have to take off the entire electronics enclosure and back panel......doing idex was a mistake........sigh.....
can't access the quick connects because of the panel and enclosure....
So I fixed that issue. The X offset ends up being still -2.5686790298390463, but my endstops seem good. It seems that -2 is probably because of this:

They are off by 497 instead of 500. But they are over the edges of the bed, as far as I can tell.
š¤ š¤ š¤ š¤ when you do the 515, is the nozzle suppose to be on the left or right side of the "edge of the bed"
This is wrong, it basically says your bed is 3mm offset from the middle, that's quite a bit of build error.
you're also missing the bed_margin_x variable.
Wow that's a lot.
there are 2 common issues for that:
1. you calibrated the endstops with an active toolhead offset, before donig a new endstop calibration run
_VAOC_RESET
2. your front z rail extrusions need to be aligned/twisted. Check if the leadscrews are centered over the oldham coupler hole, if not twist the extrusions until they areI fixed that by rotating the front left extrusion. The rear one didn't fix it. The bed is now straight with the gantry on x, and there is minute deviation along a Y movement.
I got the x offset now down to .96 something. I measured the -15 and 515 on the LEFT side of the nozzle, though this is not pointed out in the guide, I had assumed we were supposed to have the nozzle on the inside of the bed when doing the measurement, so I had lined up the left side of the nozzle when doing the -15, and lined up the right side of the nozzle when doing the 515.
and i just redid it and it's off again. which side of the bed am i supposed to set the 515 on t1?
Which side is correct?
There are no "sides", it should be centered on the edge of the bed.
That's not what the guide says...and Cruz said this as well....
Very confusing. So center the nozzle where the metal ends.
I'm talking about the nozzle being centered over the bed edge
you're saying "left side of the nozzle" and "right side of the nozzle", that doesn't make any sense.
idex_xoffset = -1.0305952544778165
Good toolhead z-offset of 0.028750mm!
Your toolhead z-offset is good!
So, i think there is something else going on here with VAOC.
I'm in VAOC right now, i align the nozzles, i click back to t0, its misaligned, then back to t1, its misaligned as well, but if i click back and forth between them, its misaligned in the same spot every time
the reason for that is what i just told you
no no
yes yes
so like, if i reset, it happens in the same spot
reliably
trust me, its your gantry and/or the belts
why then, is the motor tone different
1. skewed gantry
2. a gantry that isnt skewed but forced with belt tension into alignment
3. too loose belts
4. unequal belt length
5. unequal belt tension
its one of these or multiple of these
there is a tone coming from the motors while re-positioning, but if go to t0, and then back to t1, the motor tone is different
thats normal
ok
it's not off on y, just x
sigh
So I loosened all the screws on the x Gantry and it's tilted by this much
Takes less than a pound of force to straighten it I mean I can push on it with my pinky lightly and straighten it
All the belts are off right now
