Hey, I welcome the questions, I get to flex a little bit 
Continuous ramp is essentially a boring operation, and so long as you aren’t cutting more than the maximum step down you set (in my case .01") you should be okay. There might be some strain on the z-stepper, I’m not familiar with NEMA17s or their power, but I don’t think it will be too big of a problem. I have mine set to a 6 degree ramp that slows down to 15"/min or so. The CAM operation can take distance, but I find manufacturers list their ramp in degrees so I always use that.
I think pocketing is a really safe operation in terms of chip evacuation. Granted if the pocket is way too small you can still have problems. The good news is that a .2" pocket is small enough to bore out. I usually do this for holes that are less than 2x the cutting diameter (.25" wide for 1/8" endmill). It’ll go a lot faster and you shouldn’t have too big of an issue with chips.
