Déconnexion en pleine gravure

Here is a post from last November having similar issue:

Try running the job at a lower power setting and see if it makes it all the way through. We’ve seen a lot of disconnection issues with Ortur machines and I’m not sure why they are so much more sensitive than anything else we support. Use a good quality, shielded USB cable, preferably with a ferrite ring at one end at least Make sure the USB connection is secure on both ends, not loose Make sure the power supply is sufficient to supply the laser. Ground the frame of the machine - one…

And then an updated post from last December

In the preview, scrub the slider to the point where it stopped and click ‘Start here’ on the bottom. That will run the job starting from that place. The Ortur disconnection seems to be a grounding issue - IE, the laser has rubber belts moving over plastic wheels which causes static build up. When it discharges through the USB port, it kills the connection. If you ground the frame to something it seems to help.

And January of this year confirms the solution:

Problem solved !! Thanks to Ortur Support who did really great. My problem was due to my grounding, which was not properly done. Static electricity bursts from the X belt’s movements was causing the disconnections/error:8. We attached a copper wire on one of the 4 screws of the laser module’s top plate. Wire then connects to a X-axis’ gantry screw. From that screw, another wire goes and connects to the Y-axis’ gantry screw. Wires go through cable looms to keep everything neat. Since then, …
