Cannot run calibration until all axis are extended fully

Troubleshooting
1

I have finally built a frame, and I am attempting to run the calibration for the first time.

Steps taken:

  1. lower z to minimum
  2. set the configs as shown below
  3. retract all (wait until all belts are fully retracted)
  4. extend all
  5. pulled all belts out to the frame anchors
  6. click on callibrate

result:
no movement, log shows:
[MSG:ERR: Cannot run calibration until all axis are extended fully]

What am I missing?
I tried pulling all the belts out to 100%, but I’m still getting this error.

Thanks!

Same error:

[MSG:INFO: Extending all belts]
[MSG:ERR: Cannot take slack until all axis are extended fully]

note: I just updated to the latest firmware, and this error still occurs.

output of setup/test:

Hmm… when you extended all the belts is the fan still running on the maslow or did it turn off? If not off, then they are not fully extended and you can try to pull on each again.

thank you!
That was the issue… I thought I extended them enough - the fan is a great signal!

when extending the belts, don’t just run them until they reach, run them until
they stop feeding out.

@bar, why does it complain if the belts aren’t extended enough?

That’s a good question. In theory there is no need to pull the belts ALL the way out, but in practice there are lots of things which can go wrong if the belts aren’t fully extended…mostly way’s that it can end up spooling out the extra really fast causing tangles. I think that making it more tolerant (here and generally) is important to make the user experience better, but having it handle every possible state gracefully takes a lot of careful planning to make sure it works smoothly (ie what happens if we start calibration without the belts extended at all)

I was having the same issue. It seems like pulling the belts one at a time until they stop extending solved the issue. When I tried to do multiple belts at the same time, I ran into issues. If something goes wrong, it seems like you have to take the belts off and fully retract??
