Welcome @SteveT!
Yes, as @Aiph5u mentioned, the 611 physically won’t work on the 1F (possibly, if you were to get an 80mm spindle holder & make a reducer bushing).
I’ve had both the DeWalt 611 (on my previous X-Carve) and currently use the Makita on my 1F. I couldn’t stand the DeWalt just from the pure noise factor. That thing screamed like a banshee. By comparison, the Makita is nearly whisper quiet.
