-U: Create a user's disk quota database file
-G: Create a disk quota database file for the user group.
-A: create a quota database file for all disks. When this parameter is used, no device is needed.
-M: clears the previous disk quota information. this parameter is required when you create a pair/partition.
Step 3: Enable Disk quota

RP-SLICEModule:
The RP-slice module establishes an slice format interface between mimics and most RP machines. The RP-slice module can automatically generate the supporting structure required for the RP model.
Fast and accurate data conversion for RP machines:
The RP slice technology can be used to process large files and maintain a high resolution. When a sliced file is created, the resolution of the RP model is improved using a cubic Interpolation Algorithm.

, the minimum voltage after use is over 3.7 for a single chip (remember not to put it over), and the retention voltage for long-term use is preferably 3.9.
Motor:
KV value of the motor: motor speed (no-load) = kV value x voltage;
For example, the speed (no-load) of a kv1000 motor at 10 V is 10000 RPM.
The higher the kV value of the motor, the smaller the torque provided. Therefore, the kV value is closely related to the slurry size. The following describes the slurry configuration experience:
