Could you please expand the question, possibly with images, what is meant by previewing G-code while printing?

What Firmware are you using? Because you need to modify the firmware.

If this is related to print preview image, the MKS has a dedicated software/firmware release showing a preview of the model (probably generated from G-code). It might be the case that the Bigtreetech is an older fork of that branch, you could look into that.

I'm using version x.x.25 and I've made the changes in the firmware that I've found that relate to g-code preview, but I just get a blank icon displaying and now there is a long filename error when using the SD on the main board. I suspect there are other places to make changes in the firmware, but I am not finding them - I was hoping somebody else had experience with this.
