I finally got my machine built and was going through the calibration process. I’m running a vertical setup. I retracted belts, extended, then hit calibration. The machine goes through various points in the calibration then stops randomly (it always seems to happen at different points). The fan goes off and the computer displays the the “calculated fitness is too low and will automatically try again”. It keeps doing this over and over again. Not sure what I’m doing wrong here.
I read that someone here was having a similar issue and that it was fixed by updating firmware the other Maslow files. I downloaded the latest firmware (1.7) and that successfully installed. I used the maslow.yaml file from the 1.6 assets as there wasn’t an updated yaml file in the 1.7 asset list. Finally, I downloaded the index.html.gz. My computer seems to change the file to index.html (without the .gz). I changed the name back and installed it. It seemed to upload and replace the file. I restarted the machine. Now I can’t get anything to work. The machine won’t connect through the network and the internal wifi doesn’t show up. What did I do and howe can I fix this?
Ok I was able to re-flash the machine and reinstalled Firmware 1.7 - still no idea what happened other than a corrupted file somewhere. The calibration issues are still happening though. It will run the first few steps where it slacks the bottom lines, moves, then retracts. This time it got through about 4 of these then it started the “calculated fitness is too low and will automatically try again” it keeps running this over and over again until the machine lost connection with the computer.
Just to update, I finally got through calibration. It seems I had some rigidity issues in my frame. Once I fixed that, the calibration worked. I used a smaller grid (3x3 300 x 300) but I might run a larger calibration later. I still had to retract/extend twice to get it to work however. Now that calibration is complete, how do I know how accurate the machine is?
Frame flex can have a significant impact on calibration and accuracy.
But to check accuracy you really need to try cutting something. Note that accuracy will vary across the cutting area. There is a calculator somewhere (an excel spreadsheet I think) that can show you the sweet spot for your setup, and where to avoid.
