Titl bed -issue with z-tilt
Hi guys,
I just finished building my VCore4 500 and I'm currently commissioning it, but I'm running into a lot of trouble. I was able to play around a bit, move the print head, and melt some PLA to test the extrusion and the filament sensor. However, since I tried the Z-tilt function, I've been having issues. It stopped during the first attempts, saying that the value was increasing instead of decreasing. Now, whenever I try to home the Z-axis, it tilts like crazy and makes a lot of noise on the affected stepper motor.
Where is the Z-tilt data stored? How can I reset it? Even if I relaunch the process, it always starts with a HOME XY and then tilts again. I tried removing the Z-tilt section from the printer.cfg, but the issue persists. It was working fine before I attempted the Z-tilt function.
Another question: Does the BEACON_INITIAL_CALIBRATION require physical contact with the Beacon probe for the Z-offset? I ask because I lost the extended UHF screw (stupid mistake), so I used the nozzle to trigger the contact. I know this setup won't allow proper printing since the nozzle ends up too far from the bed.(I wait an extension replacment and a new full hotend to be sure)

This sounds like a loose coupler or bad z stepper cable. There is no "z-tilt data". It's just measuring z distance and doing runtime adjustment of stepper positions.
for the cable vs config it seem fine to me because I've done some stepper buz test and the number are what is expected to be
so how does it keep that data from restart of on the go ? supposed there are some place where it stored it for the pritn job or you run a z tilti at each start of print?
You won't be able to hear cable problems with stepper buzz, if one of your pins are loose etc.
so how does it keep that data from restart of on the goWhat data?
supposed there are some place where it stored it for the pritn job or you run a z tilti at each start of print?Ah. That's internal klipper state, it's just a flag wether z_tilt as completed or not, you can't change that.
so z=0 is the front left stepper?
it is easy to get them mixed up, so the software thinks it is adjusting one, but actually adjusting a different stepper and thus never levels the bed
yes I tested agianst this like ont he doc comment, and I used the busy stepper command individually to test this and verify this
Z0 is the front left stepper, when looking at the machine from the front.
Z1 is the rear stepper, when looking at the machine from the front.
Z2 is the front right stepper, when looking at the machine from the front.
then what Mikel said, either something is loose with one of the couplers or other physical setup, or the driver/wiring is causing an issue
yop , I've resinatll form scratch without any update and reset the htree coupler to be sure there is a small gap and well tighten, BEACON_INITIAL_CALIBRATION done, let go further thank you for pointing me to this diretcion , and for extra note it doesn't require bacoon conatct for the BEACON_INITIAL_CALIBRATION so even with my shorter noozle it's ok
great
i v'e touche a bit at the arm part that ges into the extrusion i saw on one of them it bump when z0
