Release 3.2.7

Version 3.2.7

Upgrade Notes:

• This release is compatible with RepRapFirmware 3.2 or later. It will partially work with RepRapFirmware 3.1.1 but not with any older version.

Limitations

• Due to the lack of RAM this build will not run on version 1 or early version 2 PanelDue boards that use the ATSAM3S2B chip.
  • Version 1.0, 1.1 and earlier v2 PanelDue: ATSAM3S2B processor (64MHz, 32kb RAM, 128kB flash) - these are the ones that the new firmware probably won't run on.
  • Version 2 PanelDue manufactured from August 2016: ATSAM3S4B processor (64MHz, 48kb RAM, 256kb flash). Will run the new firmware, but not as fast as version 3 will.
  • Version 3 PanelDue, including all 5i and 7i: ATSAM4S4B processor, 120MHz, 64kB RAM, 256kb flash. Will run the new firmware.

Changed:

• Fill left screen estate with addtional bed and chamber heaters
• Support tools with multiple heaters
• Reduced flickering while initialization
• Bring minimum and maximum axes count in line with RRF
• Respect spindle minimum RPM

Bug fixes:

• First bed/chamber/tool/axis could not be removed
• On 4.3" macro shortcut buttons would not show up even if there was enough space left
• If more tools or beds that can be displayed were defined this could lead to illegal memory access
• Fix possible memory leaks in object model representation
