DMG Celos - some small tip

In this topic, will try to give some tips how you can access the Windows 10 part of CELOS user interface used in DMG mori machines along side of Haidenhain NC.
What I mean? If you poke around, probably you already know that there is VNC “remote” access to the Windows 10 computer build in some DMG Mori machines, which control the CELOS side. Yes, but that one has password that they probably didn`t give you.
For me, it was more annoying that the clock on that Windows machine was way off from the TNC640 one. So what now?

mini CNC project[300×300mm] based on 2020 / 4020 - alum. X-profiles

That is my “redesigned” idea of mini CNC router. All parts where ordered from Aliexpress or Ebay and it was not so much as cost actually.
The project took few months to assemble and to get all parts. The result is quite average but not that bad.
Axis movement is smooth with that rollers, but not very strong in that setup. If you wish to have stronger base, then your design must be with only big V-wheels, made from strong ABS plastic and maybe few of them on each side as the developer from OPEN BUILD make.
