How to change the engraving machine into a laser engraving machine

-
If mach3 is controlled, open the control box and take out the z-axis forward and reverse signals to control the laser.Under the knife to open the laser,Put a knife is closed,
The z-axis depth of the knife path can be changed to 0.1 mm of the lower knife.
I am a 10w laser controlled like this.

What types of grinders are there?

-
The main types of grinders are disc grinders, rotary grinders and various special grinders. 1. Disc grinding machine It is divided into a single disc and double disc. It is the most common application of dual disc grinder. In a dual disc grinder, a plurality of workpieces are simultaneously placed in a cage between the upper and lower grinding discs, and the cage and the workpiece are moved in parallel by an eccentric or planetary mechanism belt action plane. The lower grinding disc rotates, and the upper grinding disc parallel thereto can be rotated or reversely rotated with the lower grinding disc, and can be transferred up and down to press the workpiece (pressure adjustable). In addition, the upper grinding disc can be rotated by an angle with the rocker arm on the column to load and unload the workpiece. The twin disc grinder is mainly used for processing two parallel faces,...

Stepper motor running current and subdivision drive settings

-
The  stepper motor  defaults to one step to 1.8° angle, 360/1.8=200 pulses, so the stepper motor defaults to 200 pulses, but in some mechanisms the precision is high, 1.8° is not suitable, so there is The subdivision settings on the drive, for example, a 1000 (or 5) subdivision on the drive, that is, the angle is reduced by 5 times, that is, 1.8/5 = 0.36, which means that the angle of the motor is 0.36° per step. This precision is increased by a factor of five. The current, the stepper motor has a rated current, for example, the rated current of a click is 4A, if you select 2.25A on the drive, then the motor’s strength can not reach its original torque, but you set it to 5A Although the strength is large, the relative motor heat is also increased. The current setting needs to be set according to the actual situation. Generally, a small load has a low current and a small current, while a high load requires a large current. There are no mathematical formulas, which are al...
