Hello ytliu.
I am experiencing some similar problems.
I will try and be a brief and accurate.
Power up, Main screen no problem.
Parameter screen no problem.
File page when entered udisk-sda [DIR]
                                  udisk-sda1[DIR]
                                  mnt [DIR]
                                  linuxrc  98572 bytes.
It makes no difference what ever keystrokes i enter I keep going in a loop with ... [DIR]
Richard sent me the factory instal which I uploaded.
Reset all my parameter variables and currently the machine will work and cut metal.

When I insert a Format 32 USB stick (cleaned) and only the nc file copied onto it, I get the following.
firstly I have to insert the stick after power up, if not it wipes all my parameter settings back to "factory" settings.
So the stick is inserted after powering up.
press the page R and the ... [dir] plus the nc file.
When I enter into the [dir]
I see the following udisk-sda [DIR]
                            udisk-sda1[DIR]
                            mnt [DiR]
When select mnt [DIR] next is nand2 and nand1
finally the uservar, settings , probe etc are listed.
But the uservar and settings are dated back to 1970, although I entered new parameter setting last week.
It seems as though either files are corrupt or duplicated.
I have not entered in copy and paste delete ins etc. as I am not that conversant with the file management.
I repeat i can use the controller and cut metal, but i need to be able to download the cutting uservar and
settings as introducing all the parameters each time inconsistent file operations is a time consuming job.
Sorry to be so long in explanation, just trying to be a precise as possible.
Hope you can help me.
Thanks
