Gap to extrude support

[Anthony-MCTM]

Hello Simplify3D's community,

I'm not English I hope you will easily understand me.

I am preparing a Gcode to print a part with PVA support.

My problem is about visualisation in S3D.

If I keep the original setting for my printer (Raise N2+), the visualisation of printing is wrong.
There is a gap between where support will be printed and where support needs to be printed. Look at this photo

The original setting for the tool 0 (left) is 0,0,0 and tool 1 (right) is -25,0,0 whereas in reality the right extruder is +25 than left.

If I change the tool 1 settings to -25 from 25 it keeps the gap but in inverse, not well.

If I change the tool 1 settings to -25 from 0 it is correctly adjusted but I fear that it doesn't considerate the real gap. Look at the photo

How can I know what is the good settings for my Raise N2+ ?

Thanks for your help !

There's lots of posts about this and the Raise3D. If you read about it, the Raise3D is using the Marlin firmware, but apparently they didn't set the toolhead offsets properly in the default firmware and then disabled the ability to set them yourself (for example, using M218). That seems pretty silly, but the result is that you now have to manually shift every XY value in your gcode file that is printed by the second extruder. So what you're seeing in the preview is exactly what you have to send to the printer to work around the wrong firmware.

If you want to fix it, I think you can just download the Raise3D firmware and set the toolhead offsets properly in the Configuration.h file. No idea why it doesn't start that way from the factory though...
