3ntr A4 V2 Quick Start Manual - page 17
Be sure you are running the latest firmware release
It is always better to have your machine running with
latest firmware: you get better performances and better
prints!
To assess wich firmware is loaded on your printer, use
Repetier Host (or any other printer management app,
that can show printer return codes) :
1. Connect printer to your
PC, turn both ON, then
start Repetier Host.
2. Be sure to have your
log ON (Fig.9), to show
printer return codes on
the lower screen area
3. Use the “manual
control” tab to send the
M505 command to the
printer
4. The printer should
return the current
loaded version (in Fig
11, is is 18.08.14)
5. If the firmware in your
machine is older than
the one currently available on your website, you should seriously consider
upgrading. It'FREE and it will surely improve your product usage. On first batch
machines, this command doesn't work: therefore it's one more reason to
upgrade!
