A few things scratched the surface...
Your firmware is quite outdated: 1 see version 1.15.1.20 on your display... now we're on 1.15.8.15.L1.. You can download it here:

Then I see quite low acceleration speeds.. a cut accelleration of 10mm/s^2? it will take 30 seconds to reach a lousy 300mm/sec!! Your machine is not that big..
Start with 1000 for all engraving and cutting... If it stalls, you can lower it a bit (or crank the motor-current)
Set speedfactor to something bigger like 1.0
The Jerkfactors can be set to numbers like 150000 or something
this is what is in my machine, and I didn't even had time to tune it..
Also check your manufacturers setting . To enter that menu: Press and hold STOP and then press SHIFT
