Progress! That is a sign that the machine still doesn’t quite know exactly where it’s anchor points are and it thinks that it needs to extend that extra belt out to have enough to reach that anchor point.
Really the only solution is to find the correct anchor point locations. All of the math depends on those being correct.
Do you noticed anything being weird during the process? Does that belt get fully tight with each measurement? Could it be catching on something during the process?
Can you post a picture of your setup? I usually cut bigger things. But 1/2” is a lot more than I have experienced. Size of bit, run rates, depth all matter. There is an art to this. What type of wood were you cutting.
So I recalibrated a few times.It seemed that the belt was behaving. Then i ran a file, got part of the way through, and the belt slack increased significantly then went into alarm flashing red lights on the unit and communication dropped. I can’t be sure of the order but it could lose communication first, then belt slaken or vice versa. I just retried again with a new G-code and same thing happens. I have to restart, retract belts and tension belts before i can clear. Heres the log from the last attempt

error:152 - Configuration is invalid. Maslow.yaml file may be corrupt. Turning off and back on again can often fix this issue
Bar, I’ve hit the wall. I updated to version 1.14. Looked promising, got most of the way through a longer test, then the same problem with one motor kicking out excess built, except it went into alarm, then disconnected. Unfortunately, I didn’t keep the serial file. Tried it again, and it wouldn’t even run before it went into error. I guess I am done unless you know the specific fix.
I built a standard CNC machine years ago running Mach 3; it’s made skis, foils, boats, furniture, etc. It’s had its share of frustrations, but nothing compared to the Maslow, which has yet to complete a simple g file. I was hoping that the Maslow would take up less space in my tight shop and allow me to do full 4x8 sheets.
I totally agree that it is frustrating. The standard XYZ type CNCs have about 70 years of a lot of really smart people working to figure out what the best way to do this is, Maslow is still very much in its infancy and it’s just us here in the forums trying to figure out what the right way for things to work is. We’re making progress, but we still have so so so much to figure out and learn
