Marlin 1.1.9 Firmware for gMax 2 with Solid State Relay (SSR) ONLY!


Update 09/29/2020 :
+ Adjusted thermal runaway threshold for heated bed. TR will trigger if bed is 6+ degrees outside target temperature for 30 seconds or more.

Update 09/18/2020 :
+Firmware is for use with new solid state relay. The new relay allows for PID bed tuning which increases stability and eliminates temperature fluctuations on the heated bed. DO NOT USE WITH THE ORIGINAL EXTERNAL IOT RELAY RELAY SHIPPED WITH GMAX 2 PRINTERS.

+After you upload the firmware, you may have to go to "Control > Restore Failsafe" on the LCD screen to properly reset the firmware.

Update 07/29/2020 : Added in new hex files.
+ Adjusted thermal runaway threshold
+ Addition of advanced thermal runaway script. (Triggers Filament runout script in the event of a thermal runaway in order to save the current print.)
+ More probing points for bed leveling
+ Added "Level & Preheat" tool in gMax Tools
- Removed "Clean Nozzle" script from gMax Tools

Used on the gMax 2 3d printer. This firmware ships pre-installed on your gMax 3d printer.

Note
Modifying the firmware is for advanced users and it not recommended. Making changes to the firmware could cause damage to your printer not covered under warranty. We recommend just uploading the .hex file


Installation


The new firmware includes .hex files and you can simply upload using xLoader or Cura slicing software.

We recommend using xLoader to install firmware. Make sure to set baud rate to 115200
https://github.com/xinabox/xLoader/releases/

Refer to this tutorial for a simple walk through on installing firmware with Cura:
http://forum.gcreate.com/index.php?threads/installing-marlin-firmware-using-cura-slicer.1039/

If you are uploading via the Arduino environment, we recommend using version 1.9.0. Also make sure to have the u8glib library installed. We recommend version 2.24.3


Thank You

Note
Do not use the configuration files for the gMax found on the github page. Always download the gMax firmware found on our forum to ensure it works on your printer.


A huge thank you to the entire Marlin Development team. We will be incorporating our changes to the Marlin github and as always our source code is available in the .zip file.
