Alfawise U20 Firmware Download UPD

I found answer of my problem! Many thanks in this post ( _and_u8glib/)

In firmware were 2 files from U8glib. I just need to find where firmware sketch directory is and delete those U8glib files from it.

Hi everyone. So recentely we got a 3d printer Alfawise U30 Pro, and we immediately began printing and learning how to use it. We came out with some really great results, but the firmware gives us some issues time to time . The version of the mainboard firmware is the Marlin1.1.9 LGT0.3.1 In a couple of times, the printed just stopped printing and asked if we wanted to continue, since the print wasn't finished. When it restarts printing, the temperatures of the nozzle and of the bed get resetted back to 0 c. Yesterday the printer just increased the temperature of the bed up to 143 c without any command. We tried updating the firmware but it seems as if the printer doesn't respond to the update, no interaction whatsoever. Can someone gives us some hints on how to solve the issue? Thanks in advance! Print speed is 100 mm/s. Bed temperature is 50 c and nozzle temperature is 200 c. We use Cura to set the printer.

My Alfawise EX8 (Anet A8 Clone) had an issue, so I flashed the firmware provided on the GearBest page. After the flash the LCD is no longer doing anything and I can't really identify the LCD to confirm whether the correct one is selected in configuration.h

I know this is a closed and already answered question, but for anybody having an Alfawise EX8 and wanting to update the firmware, I've changed some things in the Marlin bugfix-1.1.x version, so that it now works perfectly with this printer. You can find it here. The issue with the display is in the file ultralcd_st7565_u8glib_VIKI.h. The Alfawise EX8 version contains added functions like contrast adjustments and addressing offset, which is not present in the Marlin vanilla version. Also, the original Alfawise firmware grabbed 93% of RAM for global variables, which lead to unstability and in my case to spliting screen and other issues. Now there are only 46% allocated. I suspect the SD alpha sorting of this, as you can clearly see in the advanced config, that it creates an array of more than 200 instances. 37B each. Sooo since I don't usually hoard gcode files on my SD card, I disabled the sorting completelly. Feel free to make adjustments to your own taste!Wish you luck and many successful prints! :)

EDIT: If you are still experiencing glithes with the LCD, try separating the LCD data cable from the extruder cables. I didn't. My bad. Also, don't add capacitors between power inputs. Caused more problems than it solved and yes, I know how to connect an electrolytic capacitor. The firmware is fully functional, working with a MightyCore bootloader inside. There was an issue with the SD print abort function. In the bugfix version, there is a gcode function added to abort SD print and it somehow doesn't work too well with the LCD option. So I removed the gcode from Marlin_main.cpp and brought some things from the original firmware to get it working. Also since the SD was really slow, I had to re-enable the alpha sorting using RAM, but decreased the array size to 30 instances. For the memory it means, that right now it is at 89% Flash and 39% RAM usage. Enjoy! :)

To be able to print objects with the Alfawise U30 you need special slicer software, in this case a program called Cura. After installing this software I updated the firmware of the printer and after that I was ready to print. There is a version of Cura shipped with the printer on the SD card, but this version is outdated. Therefore you should always download the latest version. It can be downloaded for free over here. In Cura version 4.0 and above the Alfawise U20 profile is included. To make it compatible with the U30 you only have to change the bed dimensions, because the bed of the U30 is smaller. Change the settings to 220x220x250.

Before you start you should update the firmware of your printer. These printers have a lot of firmware updates already, which is a good sign. It seems like Alfawise is very keen on supporting this device.

A group of french guys doing some great work! They made a marlin firmware, attached a bl-touch sensor, made some great mods and have several fan ducts to print so you can improve your printer a lot, for free!

Check out their forum: -alfawise/

Yes! A number of French guys are working on a Marlin 2.0 firmware for this printer (and I believe the whole Alfawise range). That means that you can leave the closed software and take the open-source and very popular marlin software!

p.s. I still can not fix the damn power off/on, so annoying but I have to live with that. Wonder if we cannot extract the dtb.img from the crappy original Android firmware that comes with those boxes. For H96+ pro there is a stock 7.1 Android. Anybody let me know if I can do something.

I have years of experience on 3D printers and a printer is basically a CNC that builds up instead of down. They both use G-Code as instructions for the firmware to interpret. With 3D printing there are 3 main steps:

The CD comes with an older version of GRBL Controller which now called Candle. I gave it a try and couldn't get the spindle to turn. After updating to the newest version I had issues with it returning to home. Not sure if it was the config of the firmware but I eventually added physical endstops.

(WARNING above command flash eMMC, You Lost ANDROID, dont do that if you dont know how to recovery android firmware, or dont want to use eMMC, SKIP to step 14 for the setup with SdCard/Usb Only)

Alfawise is the in-house brand for Gearbest.com Gearbest is well known in the community for their low prices shipping 3D Printers from China. These are clone printers, or copies of other 3D Printers. They are iterative designs that learn from the predecessors. Right now, they have 3 printers in the line. The U10 is equivalent to an Anycubic Chiron or Creality 3D CR10-S4. The U20 is a Creality CR-10 equivalent. Finally, the U30 is equivalent to the Ender 3. These equivalnices are all based on build volume. One thing I like about these 3D Printers, is the update schedules. They actually releaes regular firmware updates. That is a bit of a double-edged sword since some releases introduce bugs.
