Have gotten the message “cutter stop responding” in the middle or first hour or so of a 6 hour. Then have had to start the v carve over watching it go over what it’s all ready cut to get caught up.
5 pro 4x4
Gotten the message with and with out shop vac hose hooked up.
After the error message i get the connect to cutter box. Click it and start the process over. Or I get “the machine controller did not respond. Please make sure your machine is powered on”
Normally this is due to static electricity build up or a bad usb connection. Especially as the temperature drops outside (not sure where you are) but static seems to build up and causes disconnects. If you are using a trim router as the brushes wear down you will get the EMI disconnects as well. You can look in the vent on the trim router and see “sparks” as an indication. There is lots of documentation on the forum for EMI, USB, and disconnects. Hope this helps.
If you decide to use the 4" system, you can get adaptors and 2.5" hose.
On my system, I have 4" going to a 4" blast gate. From there I use a 4"->2.5" adaptor, and run that to the machine. On the end of the hose is another adaptor for hose to the sweepy. It’s the same size as ‘standard’ larger wet-dry vacs use.
The hose I use is wire-wound for support. To ground it I just connected the wire to a ground, done.
