Updated to 0.78.1 and ran the calibration. I haven’t seen this error before.

any chance that you had multiple browsers connected to the maslow? that can
confuse it (it doesn’t know which browser to send calibration to)

Nope. I run back and forth from my desktop and just have one tab open in chrome.

That error usually means that the computer fell asleep so when the machine tried to send the data it didn’t respond. I wouldn’t expect it to lead to any issues
I’m getting the same error on version 0.81 (the latest update), I haven’t left my laptop or even change tabs or open a different browser. I noticed the error when it kept coming up over and over again it used to say on previous calibrations (WARNING FITNESS TOO LOW. DO NOT USE THESE CALIBRATION VALUES!) I need help!! don’t know what’s causing the issue.

You are getting the error message “Calibration data not acknowledged by computer” over and over again?
Yes!! here is the log I recently saved 5 min ago

Try refreshing the browser window, that might fix it

Excellent!
There are usually one of two issues when you get a number like that where the fitness is low but not like way too low.
-
The magnet could be slipping in the roller. The way to test that is to do Retract All → Extend All → Retract All and see what the numbers that get printed out for the offset are. We want numbers close to zero
-
The frame could be flexing leading to inaccurate measurements. How rigid does the frame that it is attached to feel?

I checked the magnets and they looked fine and nothing seems loose and checked the frame and I put some extra screws to see if that was one of the problems and it still gets stuck in the same position. here is a picture and a log from this morning. Still not sure what is causing the problem with the FITNESS being low. Can’t get past the calibration. Maslow-serial (4).log (6.1 KB)

Yeah, that is weird. Your frame look super solid so I don’t think flex is likely to be the issue.
Did you give this a go?
yes before I took apart the M4 to check how the magnets are it would give me from single numbers to 3 digit numbers and once I put the M4 back and checked it again it was in the 0s to 10s and that the same results i keep getting so I decided to run the calibration to see what error would give me but it still the same error.

From looking at your log it looks like your calibration values are already reasonably good, but maybe that’s causing some issue. Can we try starting with a slightly different initial guess for width and height? It’s possible that something is tripping up the math and preventing it from finding the correct answer with those initial conditions.

Hi, I’m giving an update on my situation and !'m still getting the same error as last time, I did everything and still having problems with the fitness being to low. I checked the motors and the magnet clean them and everything looks good. My guess causing the problem could be the motor or the magnetic encoder board not responding right. my number go off my 100s even do the belts are the same length after extracting and retracting. Is there any possibility that could be causing the problem?
This is 100% the issue. If you do extend and then retract you should get a number very close to zero.
This is most likely caused by an issue with the magnets in the rollers. The first thing that I would check is to see if they are fully glued into place, if the magent is able to rotate in the roller you can get an issue like what your are seeing.

Yes all 4 magnets are glued fully. I gave it a gentle push with a 1/16 driver thru the bottom hole and didn’t move at all I clean it off and nothing. i check all the screws are tight properly and nothing is loose and can’t seem to find the solution to my problem. The M4 is up to date and my only guess is a faulty Motor or the encoder board not reading the magnet right.

the problem is the magnets rotating in place, not pushing in or out.

If you do Extend All → Retract All what numbers do you see printed out?
Hi David, I understand what you’re saying but this was the only way to check if it was glued in place, that’s why I tried to push it out gently but all 4 are glued and while checking the magnets I clean the encoder board and check if anything was loose but nothing , everything looks good. I put it back together and still have the same problem like I keep mentioning.
