Help identify this printer  

RE: Help identify this printer

It looks like it might be a Chinese clone of the Original Prusa i3 (MK1, circa 2015) with some mods added.  You'd probably have a lot better luck posting on a general 3D printing forum on the likes of Reddit or Facebook.

Thanks for your advice, I did suspect this printer was a clone. I'll give the Reddit/Facebook forums a try. The AVM20 Lite board is made in Spain (where I am living) so it makes sense the printer having mods made here.

I would try to connect to it using Pronterface (any serial terminal will do) and do an M503 to dump the settings to the terminal.
M503 is the G-CODE for Report Settings.

Then use those settings to install a fresh Marlin 2. (2.0.9.3 is the current stable version).
From there you can fine-tune and mod it any way you like.

I used this frame upgrade when upgrading my MK2 to MK2.5s and can recommend it if your clone has the same frame dimensions.

Can anyone identify this printer for me? It requires a new LCD unit that I have located but from what I have been told  it was running Marlin  with Spanish as the selected language. I would like to change the configuration to English but without knowing make or model I am reluctant to to mess with it. It has an AVM20 Lite that is a combined driver board/drivers/ AT Mega that is compatible with the  Arduino Mega 2560 plus 1.4 RAMPS board so should be easy enough to install Marlin but which flavor?

 

There are plenty of inexpensive upgrades you can make to quickly enhance it also, for instance that the threaded z axis rods are held in place by a thick adhesive tape you could replace it by using flexible couplings (even 3D printed ones can be a big improvement) and even replace the threaded rods using better quality leadscrews.

However, I would not spend excessively on it. It's a good project for those who want to start up the printer yourself, but when you're not seeking an idea and simply require a printer you could make use of, it's better off buying something similar to an ender 3.
