I have searched the forum looking for a similar issue but have found nothing.
I am working with a large piece of wood - 2.25" thick. Loaded it today, started the project and started to walk away. Heard some clicking and the carve motor pulled way down. Ran (literally) back to the machine to see what was going on. The machine was still carving, but it was off on the Y axis. It was carving about .25" too far to the left. I stopped the project, inspected the machine and found nothing wrong. Restarted it just to see what happens and it seemed to carve correctly - sorta.
Here is what I know...
1. The Y axis motor makes a loud humming or grinding noise when the truck is at the far left (towards the keypad). Only happens when going through the pre-carving setup. When the truck has moved to the far left and can move no further, the motor seems to be trying to continue to move the truck, and eventually the noise stops. I don't remember my machine NOT making this noise at this position - assumed it was normal, but now I'm wondering why I didn't ask sooner.
2. The project I am working on is supposed to be 7.25" across the Y axis, but it was only carving about 5" before I stopped it. I realize this could be an error on my part, but I have used this project many times and have had no problems size-wise previously. Why it would carve the wood precisely, but smaller is a mystery to me.
3. This should be a no-brainer. When I heard the carve motor pull down, I didn't notice at first, but the 1/8 carving bit had apparently burnt the wood, and the bit! Maybe the maple wood was too hard and the bit too dull and it caused the motor to pull down. But I have only have about 60 hours on the machine and less on the bit.
4. After I completely powered off the machine and inspected it one more time, I found that the truck did not move in a normal manner across the track. As I pushed the truck to the right, it would move slowly like it should when the motor is slowing it down, then it would move fast like it was free. This change between fast and slow happened about 4 or 5 times as I move the truck once, in one direction only. When I began to move it the opposite direction, it felt engaged with the motor and continued to feel that way as I moved it to the left and the right. I checked the teeth on the belt, and the gears and found nothing wrong.
So, those are the facts. I have to believe the noise I hear from the Y motor has something to do with the problem. But the fact that I don't ever remember that noise NOT being there, confuses me.
Do I have more than one problem here?
FYI, using 1.152
