It’s quite likely that you need to increase the current on your motor drivers. 75mm/sec^2 is not fast for acceleration, so either your motors are very weak, or the current isn’t high enough to give you the torque you need to move your gantry.
Your profile says “Homemade diode grbl arduino”. I would look for mechanical issues - loose belts, pinions, or set screws, binding on the rails or bearings, as well as looking at how strong your motors are. Are they easily moved when the controller is powered up? If so, that’s not ideal.
I would also set $1 to 255 - That leaves the motors engaged at all times, instead of turning them off after a moment. That all by itself can cause missed steps and problems.
$30 should be either 255 or 1000, and make sure the “S value Max” setting in the Device Settings in LightBurn is set to the same value. $31 should be 0, not 1.
And finally, your steps per mm counts are quite high. Do you have high gearing, or just really high micro-stepping? If you’re running an Arduino, having a high microstep setting makes the controller do more work for very little gain - It’s worth lowering that if it’s not a mechanical limit.
