Endless Calibration, always gets stuck in bottom right corner. Lifting sled, unsure where to go now?

[Benny]

Hi there!

After an initial cut a few months ago, life got in the way and I’ve only now come back to the Maslow.
Around the time of the initial cut, the retraction threshold was getting quite high, so I decided to do some maintenance and see if I could make things a bit better. Unfortunately I made them worse!

Here’s what I did:

• Disassembled arms, applied some grease as the bottom two were binding up
• Reassembled, ran calibration
• machine would always stop at the bottom right and get stuck in endless calculation (left overnight multiple times)
• Found I put too much grease and it was being affected by the cold weather
• disassembled again, cleaned out the grease, applied silicone lubricant
• re-assembled - with the arms from bottom to top: BL, BR, TR, TL
• same issue with the calibration - gets stuck in bottom right
• re-flashed firmware 1.7, uploaded fresh index and Maslow.yaml
• Ran calibration on 500x500 3x3 - successful
• moved machine around the spoil board - when getting to the bottom left, the bottom two belts started to get loose
• Maslow seemed too tight in parts, bottom of sled was lifting, jerky movement
• applied silicone lube to bottom of sled - same issue
• tried re-calibrating on a 5x5 (?) and 1000x1000 grid - again stuck on bottom right.

It seems like these are getting progressively worse over time.

The initial values look quite good:

@Benny

Fitness: 0.7421742 in 2200

And then the next set of points seems to make things worse.

Does it seem like there is anything funky with those measurements? (like to all four belts get fully tight at each measurement?)

[Benny]

Hey @bar

Not 100% sure about belt tightness all the way through that initial calibration, but certainly when jogging later the bottom two became loose.

The bottom two are the arms I’ve been having the most trouble with - this time they’ve been assembled and when assembling then seemed free, but the numbers are getting high again now

The retraction force was sitting quite happily around the 1200-1300 mark, but over a few attempts at calibration that is now starting to creep up. I’ve noticed that sometimes when sending the retract command, one or two of the belts wouldn’t retract until I chose extend, just move them a little, and then retract seems to work.

So this morning I thought I’d try increasing the retraction force - and I’ve reached 1800 before all belts will reliably go in.

The bottom left belt is the most reluctant. At what force are we entering belt snapping too much force

territory?

I tried running calibration at 1800 retraction and calibration force, but then the bottom of the sled lifts so high I stopped it.
Could this be something to do with the sled being lighter because of the spindle instead of a heavier Dewalt router?

As previously mentioned, the first time I managed to get a full, successful calibration the sled was lifting at the bottom when the Maslow was on the left side of the frame. I saw somewhere in the forums people commenting on arm order, and I’ve now got it configured from bottom up, BL, BR, TR, TL. Is this bad?

[N8DGR8]

My experience:

1. Redoing the firmware with the USB C cable solves weird issues.
2. Calibration is optional if you have someone make careful measurements and you are ok at geometry.
3. Sometime the electronics board has gone bad and needs to be replaced.
4. Always keep copy of good yaml files.

[Benny]

Thanks - again still the same issue.
I’ve pulled it apart again, put the arms in the order as per the setup guide.
Reflashed firmware with USB fresh from the internet
setup on our WIFI
Retracted, extended, retracted, extended, calibrate - still gets stuck bottom right in endless loop.
I’m starting to bang my head against the wall - my partner is also fast chalking this up to ‘another adhd purchase that never goes anywhere’ - gah!!
Looks like it’s fixed the massively weird sled angle now though.

@bar any clues on what to do now? please help!

What values are in the yaml file? If you measure by hand to they make sense?

I never got calibration to work either. However, the yaml file was good and the machine cuts great!

[bar]

@Benny

Calibration values:

Fitness: 0.7950505874787801

Maslow_tlX: 10.8

Maslow_tlY: 2071.6

Maslow_trX: 3252.7

Maslow_trY: 2070.3

Maslow_blX: 0.0

Maslow_blY: 0.0

Maslow_brX: 3255.3

Maslow_brY: 0.0

It looks like you are getting good results for your 3x3 and 5x5 grid. You could just change the setting for the calibration grid to be a smaller 3x3 or 5x5 and call it done.

My recommendation is to reduce the size of the area that you are calibrating over to be smaller Like say 1000x500mm or something like that and see if you get good results there. You can always grow it.

[Benny]

Ok, I’ll give it a shot with a smaller calibration grid - but will this affect accuracy cutting larger projects at the extremities of the board?

[bar]

I’m not sure. I think that there is some middle ground which is best. Too large of a grid seems to result in poor calibration performance and too small of a grid does too.

Where exactly that sweet spot is is still something that we’re all figuring out.

[Betalombo]

Do you have the anchor points higher than the waste board? My frame is also vertical, but I’ve read that raising the anchor points in this configuration can lift the sled. I ask because TR doesn’t seem to have a steep angle like the other belts.

[Benny]

Do you have the anchor points higher than the waste board?

They’re about level with the baseboard - I’m using the 3d printed anchors from this site, that wrap around the outside of the frame and use a quick release.

Too large of a grid seems to result in poor calibration performance and too small of a grid does too.

OK cool - I managed to get a complete calibration yesterday at 5x5 - so I’ll give it a test today and see if that calibration actually gives me something I can work with. The reason I bought this machine is to be able to cut large sheets, as I’m building a camper van - so some of the pieces are going to be quite large.

Incidentally - when the calibration actually completed on the 5x5 at 1000x500, I thought - oh great, let’s see if I can increase it. So I upped it to 1500x750 and 7x7 - then hit calibrate. Suddenly the machine took off and climbed the board and tried to jump off the top - luckily I managed to grab it and pull the power before it jumped off the edge. Yikes! Any clue what gremlin could have caused that?

[bar]

There was a bug which was causing strange behavior when the calibration process wasn’t started from being powered off, but I thought I fixed that.

I will investigate and see if I can replicate that behavior.

[Benny]

@bar I’m wondering if I have another bung board?
More weirdness is happening. On boot up half the time it won’t give me the full interface or gets locked on connecting to Maslow (see screenshots)

I removed the wifi settings, set it to AP and connected to the Maslow directly, same behaviour, tried different browsers and eventually I’ll get it to give me the full interface. When I do get it, I’ve not been able to successfully retract the belts - it will only retract two of them, and the other two will only retract after I extend them by a few MM, then hit stop, then they’ll retract fine.
Once they’ve been ‘woken up’ they seem to work but for whatever reason it’s like I need to just give it the chance to move a little bit outwards.
This behaviour doesn’t seem related to the tension in the spool either, it seems software driven, as the behaviour returns after a cold boot and then all is fine after giving it a bit of extension before retracting again.

I then tried moving the sled around and around the middle to right hand side of the board it’s okay-ish - but moving to the bottom or left hand side it gets wonky, belts get slack - things wobble, just not accurate behaviour.

Given @N8DGR8 's message around checking that the values in the YAML seem logical, I checked, and they don’t.

These are the values after the only one successful calibration I’ve managed:
Maslow_tlX: -1.400000
Maslow_tlY: 2277.100098
Maslow_trX: 3109.199951
Maslow_trY: 2277.500000
Maslow_blX: 0.000000
Maslow_blY: 0.000000
Maslow_brX: 3104.000000
Maslow_brY: 0.000000
Maslow_tlZ: 100.000000
Maslow_trZ: 56.000000
Maslow_blZ: 34.000000
Maslow_brZ: 78.000000

my frame is the standard 3000x2500 mm

• So I changed them to what the popup says should be (eg. value normally 0, or width in x / y etc, those suggested values seemed in completely different places than here) - and tried a calibration again.

Clean boot, retract, extend, retract, extend, hook it up, calibrate.
Belts then tightened, and then it just slowly wound out the top left hand belt endlessly till it just limped down the board, I gave up and switched it off.

What to try next?

Cheers

[bar]

There’s a lot of things going on here that seem pretty unrelated to each other.

@Benny

full interface or gets locked on connecting to Maslow (see screenshots)

I’ve seen that happen too. Clearing the browser cache seems to fix it for me (On mac that’s apple +shift + r)

@Benny

I’ve not been able to successfully retract the belts - it will only retract two of them, and the other two will only retract after I extend them by a few MM, then hit stop, then they’ll retract fine.

This sounds to me like you might just need to turn up the retraction force in the settings a little bit. I think that whats happening is that extending them a bit just loosens them up a little more and make it easier to retract.

These seem pretty close to 3000x2500 to me.

@Benny

This sounds to me like it could be that the calibration was set for horizontal mode but the frame is vertical?

[Juan_Salgado]

we’re in the same boat. i never got mine to work, not once. i never had a successful calibration. it’s not the board, i had 2 and none ever stayed connected. none were able to fully calibrate the machine. i finally decided to cut my loses and try to sell it and warned others about this products massive shortcomings. Hopefully my efforts will save others money and time.
