Printer Speed Settings for VCore 3.1 400

In an effort to dial in my print quality, I ended up down a rabbit hole and now believe I may have some of my wires crossed when it comes to various settings. I'm running an enclosed VC 3.1 400 with a BTT Octopus V1.1 w/ F446 chip and TMC2209 V1.3 Drivers. This is what my printer.cfg currently looks like for my stepper/driver/speed includes and what I have set for speeds in the overrides. I think I may have messed up and pulled these values from the performance ratos guide which appears to be for 50v 5160's. I've seen a number of different settings for the printer overrides (z_velocity and z_accel specifically) ranging from 15 and 20 all the way to 80 and 1700. Are those upper limits/performance configs restricted to the 50v drivers or can I run them on my current setup? I don't need insane speed, but would like to have things like the bed_mesh and z_tilt be relatively quick and reliable.

Solution:
yes and no. In reality this varies from printer setup to printer setup, so if in doubt, test and find out. For 24V the performance defaults are: ```json { "performance": { "accel": 10000,...

Please upload your entire printer.cfg

@blacksmithforlife 🇺🇸 Here it is. Fair warning, it is an absolute mess right now while I move various settings around and test different things. It will be cleaned up in the final version 🤣
