I purchased this unit used and I am new to CNC. I have IT tech experience and can generally figure IT stuff out. After acquiring the unit I was able to download firmware 1.21 and basically reset it to mfg defaults on firmware 1.21 via the USB-c port and a windows surface pro.
Testing and trying to figure it out is part of the fun/challenge. Nominal progress in my learning. I saw that 1.23 firmware was released and followed the update process. It seemed to go well and FluidNC reflects the correct version.
I however have a persistent Error 503 : Server not responding. message.
I am leaning towards the manual(USBc) update process using the 1.23 and if that does not help going back to 1.21 via the USB connection.
Thoughts?
