Outputting from Affinity Design to K40 Whisperer for laser cutting

[McClary_Design]

I love working with Affinity, but I have been unable to get Affinity to export a SVG file with the proper scale.  The files will open in K40 Whisperer but the scale is always off.  I have done a google search and its not bringing up any useful answers.  Besides the scale, I am also noticing that the colors are not coming in correctly as well.  255,0,0 red for cut, 0,0,255 blue for engrave.  

Does anyone have the settings they use for outputting accurate data to K40 Whisperer?

Hi McClary_Design

Sorry to hear you're having trouble!

In regards to the sizing, please open the Export dialog and then select More. Now, make sure that Set View Box is Unticked and Flatten Transforms & Use Relative Coordinates, then try exporting your SVG again. Is the scale now retained when importing the document into Whisperer?

With the colours, could you please provide a sample of your Affinity document so I can look into this further for you? Do you know what colour space your software requires the SVG in?

Thanks in advance!

Ok, I have figured out the scale issue.  But not the color.   The color still comes into the program as black and not red.

If you want to test it,  the K40 Whisperer software  is free.

Thanks for your screenshots and a link to the application

I've been able to export an SVG from Affinity and have K40 detect the shapes and the colours used, using the following export settings -

Please note, I had to convert all objects to curves before exporting, as K40 did not like reading 'quick shapes' in the SVG file.

I hope this helps!
