Cura 4.3.0 Windows - No play button on layer view

[jakthree 0]

Hi,

Cura 4.3.0

Windows 7 Home 64bit

ATI Radeon HD 4650

OpenGL version: 6.14.10.11672

Preferences - General - Force layer view compatibility mode: unchecked

After slicing, in Preview

View type: Layer view

Color scheme: Line type

Click pencil (edit)

Color scheme dialog box shows

Compatibility Mode

Travels: unchecked

Helpers: checked

Shell: checked

Infill: checked

Only Show Top Layers: unchecked

Show 5 Detailed Layers O...: checked

Top/Bottom: yellow

Inner Wall: green

There is no play button shown.

 

The vertical slider (layer select) is shown. The horizontal slider (playback) is not shown. I want to be able to playback the tool path.  I understand that minimum OpenGL is 2.0. I have 6.14. I believe my computer and video card meets/exceeds system requirements. I have rebooted computer and tried restart Cura after making any Cura settings changes with no effect to play button.

 

Why does Color scheme dialog show 'Compatibility Mode' when Preferences - Force layer view... is unchecked?

Why is there no play button?

Why is there no horizontal slider shown?

 

Any suggestions would be appreciated.

Thank you,

That isn't the OpenGL version but, rather, the OpenGL driver version. Please find the cura.log file and check in there for the lines where it reports the detected OpenGL version.

According to this page, your GPU only supports up to OpenGL 3.3:

The features you miss in the layer view require OpenGL 4.1 or newer.

I understand now that the OpenGL Driver software (6.14 in my case) is not the same as OpenGL API 4.1 hardware. My Radeon HD 4650 graphics card chipset can only support OpenGL API 3.3 and earlier.

Thank you for your detailed answers.
