Failing to Connect

[ronald44181000]

Is it a Control Board issue when the machine will connect, but then hang in a Busy State? No matter what I do, as long as I use the NeJe_Updater_v.3.7 my machine will load Lightburn, but it will hang while at 100% and report that the device is busy. I have a replacement board on its way, but I would like to be able to use my machine in the interim to at least be able to recoup some of my investment.
Is there a Newer Updater, even one that is in its Beta Development Stage?

Hello, i bought a Neje S2 Plus motherboard. The problem is this: during engraving it stops. Sometimes I have 30.40.56% of the project. The strange thing is that symbols appear in the layer image. I use the Lightburn program. I changed the usb cable, I grounded the equipment, I replaced the laptop, I tried with all 3 firmware (all baudrate). I mention that I bought the plate separately. I use a 40w Neje engraving head.

I inform the engineer to contact you, please don't worry, if it is a motherboard problem, we will arrange to send you a new motherboard.

Please contact the store where you purchased the device to get a brand new motherboard.

Has this lightburn connection issue been determined to be a motherboard failure issue?
