Calibration failure. Can't get fitness above like 0.2

Troubleshooting
,
1

Hi, friends.

I got my 4.1 built (all parts out of the box) and a wooden frame done today but my calibration attempts keep failing – fitness too low. I’ve left it for 30 min and still never got more than just over 0.2.
Both version numbers are the latest (1.7) and I updated it today with a hard reset (button holding) and USB cable.
I’m on Mac OS Sequoia 15.5 (24F74), connecting over the maslow wifi.
I’ve got a reasonably solid horizontal wooden frame, 2476 x 3170 mm, measured center of bolt to center of bolt, see picture (3mm off in length comparing the two long sides but that’s acceptable I believe).
The floor is definitely not level though, but shouldn’t matter, right?
My anchors are 10mm bolts through the frame, fastened solid with a nut/washer and a wing nut.
Arms are mounted in the correct order.
My piece of spoil 18mm plywood wasn’t big enough to fit over three cross beams so I added a bunch of scrap OSB to get a level surface, and add rigidity.

I read about people defining frame size and z axis offsets?? I’m a newbie so I haven’t attempted any editing of the .yaml file.

What ought to be my first measures in attempting to improve the fitness to make it pass calibration?

Thanks a million.

Some folks have reported that the little tug that I give it in this video makes a big difference, that’s where I would start:

Thanks Bar. I did move it so that the TL and TR belts are tensioned before calibration, but do you mean an additional tug after the process starts?
(Also, PS, thanks for all your amazing work on Maslow.)

It looks to me like maybe there is something funky going on with the process because for some reason it seems to be starting at point 15 :confused:

Can you try turning it off and back on before starting the calibration process?

Thanks, I’ll do that tomorrow and check back in.

@bar - is there a telltale for when someone is using your interstitial FW release (seems like the kind of big changes that could throw up issues)?

This almost looks like there could be an existing running calibration being interrupted by booting the device or something odd?

There isn’t but generally the folks who have gone to the trouble to install the experimental firmware will call that out as a likely culprit.

Just checking the belts are free to rotate around the bolts, not locked down with the wing nut? Must be able to rotate at each anchor point.

Success! First try!

@RandomDave Thanks for your answer. I’m not using any experimental builds.
@ian_ab Thanks for your answer. That was indeed the case. I’ve now loosened them and it worked. I don’t think I’ve seen that information anywhere so if that’s critical, maybe it should be stressed in the calibration tutorial somewhere.
And Bar, thanks for your assistance. I did the extra tug after the top belts relaxed some, right at the calibration startup. Also the loosened wing nuts now allow the belts to rotate freely. One or both of those measure seem to have done the trick. Fantastic. I’m over the moon that this was such a (almost) trouble free setup. I’ve never built anything this mechanically complex before but with careful attention to guides and tuts this has really been such a joy to build. Now to put in a bit and get started on my first test cut. Thank you.

Here’s my log from the successful calibration if that’s of any interest:

Hi, @bar and @ian_ab it’s me again.
I came back today to try my first cut (had to wait for a 1/4’’ collet to arrive since the 240v router comes with one for 8mm, and I ordered bits from the Maslow store.). Immediately one of the motors wouldn’t retract and it suggested I recalibrate. I restarted the calibration and I’m back to the same problem as before: can’t get fitness above 0.2ish. I did the tugs and everything. This time the numbers seem different to me though. They start computing fitness but immediately (or almost) don’t get any improvements so it fails after like Fitness: 0.1848074 in 1000 (ten times trying to improve). I also notice that one of the arms hit the vertical support and stays there after measuring waypoints, during fitness, which means the machine is not sitting with the dust port pointing at six o’clock, more like five. Not sure if that matters. Anyway, here’s my log. (Had to copy and paste it because I can’t interrupt the calibration process and save the file).

Much grateful for all help, Olof.

(Oh and also, @bar, is there no way to retry calibration without having to undo my wing nuts for the retract and extend every time?)

12

I don’ think that you actually need to do calibration again.

Just to make sure that I understand correctly, we’re talking about pressing the “Apply Tension” button and one of the belts didn’t fully pull tight and so the machine suggested re-calibrating?

I think you should be good to just increase the calibration force setting a little bit and be good to go

13

Well no, not exactly. I pressed Apply Tension and one motor didn’t budge. Tried several times. Eventually I got it to go with some yanking. Then I tried jogging it around and it seemed to work. However, a new problem arose, when I went to try a cut the z-motors went all the way to the top, snapped a few times there, and now one of the motors won’t move upward. I can’t get the bit out now because it’s stuck at the bottom z and I can’t reach the release button on the router. I guess now I’ll have to disassemble anyway, and that’ll call for a recalibration I suppose? Also, I’ve seen you’ve had z-motor issues on this batch – is that what I’m experiencing? Will I need a replacement part?

14

You shouldn’t need to run calibration unless the locations of your anchor points move. Taking the machine apart shouldn’t change anything.

This sounds pretty different to me. That issue is with the boards is with the chip not being fully soldered so one motor doesn’t move, this to me sounds like both of the zaxis motors moved but not when you expected them to

15

The Z motor problem could be an alignment problem, try loosening the screws holding it to the sled on each of the motors, then running it up and down. If that works take it right down and tighten the screws again. At worst you can remove screws which will allow you to lift the Z motor out and unwind it when its free.
