Recheck all your endstops connections, something loose Wil make the stock board go nuts

I cant find any loose connections

That’s shows just a slow move. Maybe you need to check in setting that the correct board type it’s selected.

I checked that also. It happens when i turn on the machine, then when I try to cut it thinks that is the top left

The I’ll say it’s one one of the endstop cables. I had the same issue while turning on the head just went elsewhere.

If you have an optical end-stop, clean it. My upper left end-stop gets dirty from all the wood cutting and when it can’t read anymore, the machine does exactly that what you are experiencing. I used compressed air to blow the dust off.

Does the K40 come with optical end-stops?

Both mine are optical. I’m planning to replace them with mechanical ones when I upgrade the controller.

@Ashley_M_Kirchner_No @Ariel_Yahni_UniKpty thank you both for the direction to look in solving my problem. It turned out the optical was dirty, I had a piece of paper catch fire just before it started happening, the soot from that must have been the culprit. Thanks again for the help.
