Calibration log… look normal? Last attempt took all night and never finished. Thanks for any ideas.

CLBM:[{bl:3026.88, br:3021.21, tr:3077.07, tl:3060.21},{bl:3128.42, br:2932.01, tr:2978.06, tl:3149.27},{bl:3232.73, br:3021.03, tr:2869.75, tl:3069.88},{bl:3127.59, br:3124.11, tr:2981.28, tl:2959.85},{bl:3026.49, br:3227.11, tr:3089.49, tl:2852.77},{bl:2915.74, br:3146.04, tr:3189.84, tl:2938.95},]

These seem to be poor numbers, when I run them through an alternate calibration
method, I get:

1 (B): 4867.1 ± 125.3 mm
x2 (C): 4857.3 ± 129.7 mm, y2 (C): 3657.8 ± 172.2 mm
x3 (E): -4.6 ± 7.7 mm, y3 (E): 3677.1 ± 169.8 mm

those ± error ranges look really bad.

when the fitness is this bad, it’s common that the current algorithm is never
going to converge.

when you were doing the calibration, were the belts pulling tight at each
measurement point?

are the Z offset values correct for your frame? (be default, they assume that
the anchors are at the same height as the bottom of the sled) any chance the
arms are in the wrong order?

any chance the router wasn’t all the way down at the bottom?

Thank you again for the quick reply. I already had the bit… I guess I forgot to do that part when I changed my frame size. I’ll try again with the bit out and all he way down.

I removed the bit and restarted the calibration… how do things look so far? Thank you!

Forgot to add that my anchors are 1/2” lower than my sled bottom (1/2” spoilboard)

My frame is 11x14 feet.

I removed the bit and restarted the calibration… how do things look so far? Thank you!

not looking good

Forgot to add that my anchors are 1/2” lower than my sled bottom (1/2” spoilboard)

I would go in and increase all the Z values by 13mm

what are your calibration and retraction settings? if you went through and
cleaned up your spools, reduce the tension until it doesn’t reliably retract and
then increase it one step.

David Lang

Sorry; what z values are you referring to?

If you are referring to my belt spools; they are brand new; nothing ever cut. With regards to “tension” ; do you mean my retraction force settings? Thanks for clarifying.

in the maslow.yaml there are x y and z values for each anchor

ahh, so many conversations I don’t always remember who did what in what thread.
make sure the spools turn easily on the arms. The initial 4.1 kits had them
really tight, but then new spools were ordered that fit better.

David Lang

I was able to get it calibrated 2 days ago with the smaller frame… would tight spools have more effect with the bigger frame?

Thanks again for your help on this.

I had spools go from tight to super tight (900 current limits to 1800 current
limits) in two days.

when the belt is slack, try wiggling the spools on the arm, they should move
easily (not far, but easily)

image
image707×374 10.6 KB

add 13 to all 4 Z values, tlz, trz, blz, brz

in the future, you would be able to set the spoilboard to 13, but there was a
bug found that the spoilboard value isn’t included during the calibration, so
for the moment, you have to set all 4 values. (this bug will be fixed in 1.16)

yeah, when you get a fitness beclow ~0.2 to start with, it’s unlikely to recover.

12

When you Extend and connect the belts, do you have a lot of slack? If so, try reducing the Extend Distance so you only have 50-100mm (2-4in) of loose belt on your longest diagonal.

I took those numbers and rand them through the calibration process and I got:

Fitness: 1.6158592056630048
Maslow_tlX: 216.5
Maslow_tlY: 3122.3
Maslow_trX: 5435.6
Maslow_trY: 3101.5
Maslow_blX: 181.0
Maslow_blY: 0.0
Maslow_brX: 5429.0
Maslow_brY: 0.0

Which looks perfect.

It seems like there is some bug which is leading to it searching way to small of a radius for some reason. I will look into that and see what I can figure out.

The next thing that I think that you should try is putting the values that I computed into your settings file and then running the process again. If it’s starting with a decent first guess it might have more luck. You can do that here:

Ok; I updated my values… saved to maslow.yaml… and restarted… Now it won’t retract… it says failed to initialize… I’m attaching my current maslow file.

Thanks for any ideas.

You can update your maslow.yaml file manually with these values.
Over 5 metres is outside the limits, isn’t it?
and blX should always be 0 Reference Point

That is a good point, this might be too big for the belts to fully reach

I tried updating blX to 181 as in Bar’s post… but it always resets back to zero.

Currently still failing to initialize.

Ok; these are working to get maslow initializing… attempting calibration now.

11:50am update… fitness numbers are 1.4ish… 3x3 calibration seems to be working… if this works; should I do a bigger calibration like 5x5 or 9x9?
