Note: This is only an issue with the Pro machines, due to the heat sink at the back on the left.
It can be caused by a cable with too much slack in it under the gantry getting hung up on the fins of the heat sink when it homes.
To check for it, you need to turn the machine off, drop the front door, grab a flashlight and get down so that you can see underneath the gantry on the left side. There is a red cable that runs the length of the gantry, you can see it through the tube if it’s clean…locate that cable, keep your eyes on and slowly push the gantry back to the rear. If you see the cable catch on the fins of the heat sink or feel any resistance, stop.
Instructions to fix it:

(edited slightly for clarity)Thanks for posting. I’m sorry about the trouble here.
I have a fix you can try that should stop the tube from getting caught.
- Unplug the machine. Using two hands, gently roll the laser arm to the front of the bed
- Look under the right end of the laser arm to locate the red wire cable.
- Slide the wire gently towards the right and back of the unit to shift more of it from the left side of the laser arm to the right side. (You can straighten it out and feed from the left side as well. Do not pull hard on it.)
- Plug the machine back in, return the head to the Home position, (upper left corner of grid). Turn on the machine, and let it run through the Startup Calibration sequence.
Once you’ve finished, the wire should stay in place. If that doesn’t work or if you encounter any issues contact Support and tell them what you did.
