You gave me a good idea！Yes，first of all， check whether it is a raft issue.

If you imported a config from an old version of slicer, it may be defaulting to use a 1 layer raft. I don't remember when raft got added to slicer but I am pretty sure it wasn't included with version that solidoodle supplied.

This is my previous setting. If I change the first layer to 0.53, the same as solid layer, it works.
Thank you all for your patience. Have a good day!

I finally figure it out. It is not a raft. That's because I set the extrusion width of first layer to 1, but the solid layer extrusion width to 0.53. In Solic3r, the thickness of trace is dependent on extrusion width.

Just to be sure, can you post a shot of the RH slicer settings tab? Just want to make sure that Ian's suggestion is not correct. Just because it says it in Slic3r, doesn't mean that is what you are using in RH.

I am sure it is not a raft now, because the first layer is included in the 3D model. If it is a raft, it should not be part of the model.

God, no change. So it's not a raft?

below is my setting, and I am sure the profile I am editing to turn off the raft is the one that is selected in Repetier.
I doubt maybe it is the problem of Solic3r

Raft layer is set to zero, so there is no raft layer , I think.

That looks to me like it may be a raft thats being put down. You should see a setting in slicer for disabling the raft, I think its under support

I want all layers to be solid, including the first layer. But the first layer automatically becomes very thin. Just as shown in the below attachments:
I use Solic3r as a tool to generate gcode.
Anybody knows how to set the Solic3r to get rid of the first layer or make the first layer thicker?
