Greetings.

I have a Mingda Glitar 3 (china) 3D Printer, it has a large build volume of 300x200x360, however its been underperforming in proper printing. Before I declare it a waste of money, I would like to replace the board with another that are more used in the community. I attach pictures of the printer and board. Any help about the subject will be highly appreciated. Thanks in advance!

Also a link for the board:

Can you tell us in what way the printer is under performing? The performance of your printer might be limited by any of the following:

1. Firmware - in which case, installing more up to date firmware (if available) would help, or replacing the electronics by any electronics for which up to date firmware is available.

2. Electronics - in which case replacing the controller by modern 32-bit electronics and firmware would help. Some of the 32-bit options also provide a web interface and web upload to the SD card.

3. Mechanics - in which case upgrading the electronics and firmware won't help.

Also important:

- does the printer use 12V or 24V power (or another voltage)?
- what model numbers are the stepper motors? They are usually labeled.
- does it have an LCD panel, if so what type is it?
