losing my mind rn i try using a new cable and dint work ,i hope i just need to replace the connector on the black box and not a new mobo ,the power saving mode wasnt making any trouble ,i really hope ist something on the software i would love suggestions .
What kind of plasma? If it a HF Start type, probably killed the BlackBox. If its a blowback, could still be damage, but only if plasma wiring was wrong. Double check wiring, didn't use THC pins instead of Trigger on plasma side maybe? Did use Relay (not tool enable, or PWM on BlackBox side?) docs:blackbox-x32:faq-usb-connection-failed [OpenBuilds Documentation] As you mention problems started after first use, my guess is plasma caused something
the miller 375x doesnt operate at high frequenzy but i disconnected everything and the black box did connect but when i tried to setup all the cables wit psu i get closing port COM3 now it dosent dosent connect even when everything its disconnected aside from the black box ,**** it sucks and my black box model got discontinued i dont think the connection y have on the plasma to the relay could make any damage. would you happen to know if i can connect my machine using a different controlller?.
So it wasn't the plasma, but some other wiring that caused a short or some other mistake. Problems as soon as you added that wiring. BlackBox X32 is fully backwards compatible. Restore your Grbl Settings backup from the old one, using latest version of CONTROL and it will adapt settings to grblHAL for you. Wiring mostly plug straight in, just toolhead wiring that has slight differences Do find the wiring that killed the old one first though, or it might take out the new one the same way (and that sorts of damage is not covered under warranty)
