. then try to calibrate it with this method IDEX endstop calibration 1. run _VAOC_RESET 2. start VAOC - if toolhead cant reach the camera in y position increase the y stepper max position and the variable_bed_margin_y accordingly 3. make a VAOC calibration 4. exit vaoc 5. run CALCULATE_DC_ENDSTOP and copy and paste the result to your printer.cfg 6. run _VAOC_RESET 7. make a new VAOC calibration after that share your ratos-variables.cfg file and the printer.cfg file

It says gcode_macro ratos is not the valid section for bed_margin_x @Helge Keck

show me the screenshot of this error also, when did this error happens after pasting the results to the printer.cfg?

ahh, one sec
anddelbel
anddelbel5d ago
And also, is it fine if I paste the results in a line with a smaller number than the stepper motors?
Helge Keck
Helge KeckOP5d ago
i dont understand?
anddelbel
anddelbel5d ago
In the print.cfg file I’m used to paste my modifications on line 40 On line 150 there are the stepper motor lines Don’t they overwrite what I’m putting in?
Helge Keck
Helge KeckOP5d ago
make it the last text before the green section starts

Helge KeckOP5d ago
before this line

perfect it worked please show me your printer.cfg file

Nice, it gives me no error starting the print I’ll copy and paste the part before save config, fine for you?
Helge Keck
Helge KeckOP5d ago
just drag and drop the file into the chat
Helge Keck
Helge KeckOP5d ago
oh i forgot one thing thank you
anddelbel

Should I redo everything?
Helge Keck
Helge KeckOP5d ago
not needed, jsut control your parking position for T1

the heavy duty bearings are a massive improvement, vaoc was crazy tight dialed in swapping between toolheads

yes, these bearings are pure gold made out of vibranium

noise
Xulkal
Xulkal5d ago
shouldn't the xoffset and yoffset be closer to 0? or are those fine now with the earlier printer.cfg changes?
Helge Keck
Helge KeckOP5d ago
you cant do anything about the y offset and the x offset should just below 1mm
Xulkal
Xulkal5d ago
ok cool
Helge Keck
Helge KeckOP5d ago
technically after this procedure the x offset should be 0 but real life sucks sometimes
Xulkal
Xulkal5d ago
kk, those ratos-variables.cfg are from after step 8 of your instructions, while the printer.cfg data is from step 6. Should I rerun CALCULATE_DC_ENDSTOP again?
Helge Keck
Helge KeckOP5d ago
no, all good thank you
Xulkal
Xulkal5d ago
np, time to go tune up everything else again
archen

@Helge Keck when you say revert to default endstop values, you mean only dc?
Helge Keck
Helge KeckOP5d ago
x and dc

Ok I downloaded the util cfg but seems like I can't upload it due to permissions
Helge Keck
Helge KeckOP5d ago
jsut copy and paste the macro that is in green and paste it into the printer.cfg do not upload a file
archen

Aah

where can I find the default values for restoring?

if you cant find them ignore that point

my values were pretty close to the new test:nod:

Worked great @Helge Keck 🥳 now that I resetted my X endstop, do I need to tune it again to the left side of the bed?
Xulkal

Just checking in after test prints, this approach was much easier for tuning IDEX. Pretty much flawless

no

after doing this system of VAOC calibrations and running the macro and putting them in the printer.cfg.. then restarting .. T0 looks good at -15.. but T1 looks off about 2mm at 515. Here is VAOC results.

Helge KeckOP4d ago
ignore the bed edges you still have a x fofset of over 1mm, did you tuned your belts properly before doing the calirbation?
Jombo
Jombo4d ago
um no because there is no actual walkthrough on what to do and in what order for idex.
Helge Keck
Helge KeckOP4d ago
well, without correct belt tuning the VAOC wont work reliable
Xulkal
Xulkal2d ago
idex_xoffset = 0.007453416149061809 yeah, there we go, redid these steps after getting belts dialed in more
Helge Keck
Helge KeckOP2d ago
excellent, thats how its supposed to look like
ZIMZ
ZIMZ2d ago
Can you please create a guide for your belt journey in the main idex channel? It would help out others. I'm willing to help you organize it.
no_c2h5oh
no_c2h5oh2d ago
Apparently, all my problems (IDEX 500) with the "Move out of range:" were due a faulty back_clamp, that didn't hold the belt properly in combination with the default acceleration been set to 10000mm, which is a bit aggressive for a 500?
Helge Keck
Helge KeckOP2d ago
10k is nothing
no_c2h5oh
no_c2h5oh2d ago
So probably I'm not tuning my belts properly, even with the Hybrid 500 - 10K was unachievable for any meaningful print quality
Helge Keck
Helge KeckOP2d ago
well, slicer profile tuning plays a huge role as well of course and of course input shaper its mandatory to achieve good quality at high speeds
no_c2h5oh
no_c2h5oh2d ago
I tuned my Prusament PC-Blend from ground up, achieving a very good precision even better than my enclosed MK3S+ (all enclosed chambers). Never reached more than 6000 acceleration on the RatRig - above that quality is ridiculous for my needs... How would you advise on tuning belts properly? I'm using the Diyshift GT2 belt tensioner... Currently at 10k, starting the VAOC procedure brings me "moove out of range"
Helge Keck
Helge KeckOP2d ago
this is the wrong channel for it. if you want help to tune your printer for speed create a own thread in #fix-my-print and share your profile and images of the prints also, a belt tension meter is not enough, if it even works.
no_c2h5oh
no_c2h5oh2d ago
Sure, I apologize
Helge Keck
Helge KeckOP2d ago
you need to make sure you dont have any virbations and equal belt length and so on no need to apologize
Xulkal
Xulkal2d ago
Absolutely, I planned on recording a video walking through my tuning steps once my voice is back. Currently sick.
no_c2h5oh
no_c2h5oh16h ago
This procedure definitely works and the official commissioning guide should be changed, as soon as possible, for the others to follow.. Thank you all! idex_xoffset = 0.08171275776905418
