The G540 has a native resolution of 10 micro-step or 2000 pulses per revolution, which means you can make really minute movements.ДЇor controlling the Gecko G540 you can hook it up to a computer by connecting the DB25 port on the Gecko and the 25-pin serial port on the computer using a DB25 connector. This is needed to protect the motor by limiting the current going to the connected stepper motor.ДЇor example, if your motor is rated for 2.8 A, you must connect a 2.8K resistor (2.8 x 1000).Дriver G540 has a trim pot (potentiometer) near each stepper motor port to fine-tune the smoothness of rotation. This means you won't be able to extract the full potential of the stepper motor, however, it will function reasonably.ДЇor stepper motors that require currents less than 3.5 A, you will need to connect an appropriate resistor between pin-1 and pin-5.

#GECKO G540 SETUP DRIVER#

If you are using a stepper motor rated for higher currents than 3.5 A, the driver cannot supply more than 3.5A of current. However, if you are using Gecko G540 you can narrow this margin as it has over current protection and use stepper motors rated for 3.5A or more. The rule of thumb is to select a driver that can supply 1.4 times the current needed by the motors, this is to protect the driver from high currents due to load fluctuation or hard stops. If you want to use a high torque motor you will need a driver that can meet the current demands of the motor. The torque produced by the motor increases with an increase in current. It can supply a maximum current of 3.5 A to each motor that it drives.ДЇor example, a typical NEMA 23 motor with around 180 oz-in of holding torque would require around 2.8 A current. If you keep the current within the rated values, there shouldn't be an issue. The only possible drawback is the heat management, and the G540 is extremely well designed to manage heat. Generally, you want to apply a higher voltage to get high torque even at high RPMs. More voltage to the stepper motors translates to a faster rapid speed of the axes. You can use stepper motors with a maximum voltage rating of 50 V.

#GECKO G540 SETUP DRIVERS#

G540 has four Geckodrive G250X Digital Stepper Drives, one for each stepper motor that it can control.Д«efore you get confused, know that the G540 motor controller is actually four G250X stepper drivers rolled into one board.

In most other stepper drivers, you need to purchase a stepper driver for each motor you need to control. Definitely the lesser of two evils.The Gecko G540 can control up to four stepper motors. It's really worth doing the same way as everyone else, and accept that there will be a short learning curve to climb.

Forget any CAM software, unless you want to draw everything as a mirror of the desired object so that it comes out right on the machine. What you are trying to do is set up a left-handed coord system, and you are going to be out of step with the rest of the world. Everything - and that means everything - assumes a right-handed coordinate system. However, if you think that you might addle your brain to do it the 'conventional' way, then you are going to get double-addled with spots on if you then want to use any CAM software. are you saying this cant be done? or that home wouldn`t be at machine 0,0?You certainly can set up Mach3 to do that - it's just a matter of setting the 'direction' flags appropriately in Mach3. I would like my top left corner to be my 0,0 and bottom right to be +1000,+750 like a sheet of print, I have used coreldraw like this for so long my tired old brain struggles with anything else.
