Gaps on Pause Resume
You can find the macros in the RatOS folder, I think they are in the macros.cfg (off the top of my head) and some of the other unload/loading macros in the macros folder under loading_macros.cfg and unloading_macros.cfg (or something like that). Copy the relevant blocks into your printer.cfg and change values there.

Gaps on Pause Resume
Yes, that makes sense. My solution right now doesn't fix the issue entirely, but it helps a bit. I changed the resume macro so that it does a few quick slamming extrusions at the end to help try to build pressure, and then once i resume i go at 50% seed for two or three layers. I wish I knew a better fix to this, as it's not perfect, but its slightly better.

Gaps on Pause Resume
I just started to encounter a similar issue and was going to post about it. If this doesn't sound like your issue, let me know and I'll move the conversation elsewhere.
For the past few days I've been troubleshooting under extrusion on a resume after a filament change. I found that if you just do a pause/resume without a filament change, there is no issue, however, if you use a filament change, i experienced extreme underextrustion in the following layers. I narrowed it down (after a lot of testing) to the inability of the nozzle to re-gain nozzle pressure after the change. Even with extended purging after the change, I could never get it right. I fixed this by making the printer do a prime blob after the filament change, which builds more nozzle pressure and hence the problem was gone. Unfortunately this is obviously not a permanent solution, but it might give some insight into maybe a similar problem.

Z shift - gap on layers after M600 filament color change (VC4 500)
Anyone ever find the root cause of this?

Good mesh, bad first layer.
So just in case anyone else is having this problem. Even though it said i didn't need the scan compensation, I found a thread that lead me to believe that because of a certain setting I had on, I needed it to determine the thermal offset compensation. So I ran BEACON_CREATE_SCAN_COMPENSATION_MESH BED_TEMP=85 PROFILE=Contact , and it fixed the first layer, now it's printing perfectly. Interestingly enough, the contact mesh is a near inverse of the normal scanning mesh. I'm not sure what that says about anything, but it was just an observation.
