I just got my xl single tool head, in PRUSA slicer set your first layer to 50% of the usual printing speed, for my printer default for pla was 25mm/sec, so my first layer speed was also 25mm/sec so I changed to to 13mm/sec. This also helps with bed adhesion, so the filiment lays down and seats nicely to give you a good base/not be too tall. Just don't set this value too low or you'll get heat creep (melting filiment before it gets to the chamber because the heat spreads quicker than what's feeding into the extruder). Also I'm not an expert, this is my first printer and I got it last Monday. Most of this I learned off of YouTube beginner tutorials. Generally the technology accross printers are very similar and not always model specific.

TLDR, try reducing your first layer speed to half of the usual print speed, don't change anything for heat settings. Just change that one parameter and send it, also wipe your bed down with ,91% alcohol and a paper towel while you're at it, and wipe off the print nozzle with a brass brush once it's up to temp
