Hello, Do you know of anybody supplying replacement control boards and/or firmware for these machines? The Anet website appears to be dead. when I go to the site it opwns to the main pabe but I cannot log on and if I select another page (shop for instance) I get 404 message. The A2 has developed a fault that, to my mind can only be down to the board/firmware, it will print for about 45-50 minutes and then just switch off completely, 10-15 seconds later it switches back on again, but of course the print is then lost. This happens whether it is printing from the sd card , from Repetier or Pronterface and I have tried 3 different power supplies all with the same results. Any information would be greatly appreciated PS. There is no indication as to the ID of the firmware other than the screen looks very similar to my delta running Marlin. https://reprap.org/forum/read.php?146,873744,873744#msg-873744 Mon, 20 Jul 2026 21:37:00 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?146,873744,873807#msg-873807 https://reprap.org/forum/read.php?146,873744,873807#msg-873807 catmandu Firmware - mainstream and related support Mon, 15 Jun 2020 09:30:08 -0400 https://reprap.org/forum/read.php?146,873744,873801#msg-873801 https://reprap.org/forum/read.php?146,873744,873801#msg-873801
Could be anything causing it to reboot. bad solder, dying cap, fault regulator... really not worth the time it would take to diagnose.]]> Dust Firmware - mainstream and related support Mon, 15 Jun 2020 08:10:25 -0400 https://reprap.org/forum/read.php?146,873744,873798#msg-873798 https://reprap.org/forum/read.php?146,873744,873798#msg-873798 Would you have any idea what could be causing the machine to just shut down completely and after a few seconds switch itself back on again? as I say I have tried printing from the SD card, Repetier and Pronterface with sliced files from Cura and Sli3r and changing power supplies, so the only thing left is the board.]]> catmandu Firmware - mainstream and related support Mon, 15 Jun 2020 07:34:25 -0400 https://reprap.org/forum/read.php?146,873744,873794#msg-873794 https://reprap.org/forum/read.php?146,873744,873794#msg-873794
So you can upgrade your firmware to latest marlin when ever you like.

[github.com]

But this controller is a sanguino1284p based board so it has limited flash ram so you cannot enable all features and you may need to add a bootloader or program it with a AVRISP


I don't know of any drop in motherboard replacements... you might have to add mounting holes.

But the plugs look very close to standard..

If it was mine I would try for a skr 1.4 with tmc2209 stepper drivers.]]> Dust Firmware - mainstream and related support Mon, 15 Jun 2020 06:35:26 -0400 https://reprap.org/forum/read.php?146,873744,873744#msg-873744 https://reprap.org/forum/read.php?146,873744,873744#msg-873744
