I cannot find a driver for the NEMA 14 Stepping Motor (17 oz-in 1/4" dual shaft) on your site, would something like the Pololu DRV8834 be okay? (I note that the stepper requires 2.7v)

We don't offer those drive pullies with a 3/4" bore at the moment. We can supply them if you are willing to wait. If so, what is the pulley pitch, how many teeth and the width of the belt.

Meant to say pulleys, not pullies.

If you are using a spindle with a VFD, there is a 24 volt power supply that will provide the correct power for the V+ and V- on the Mach3 USB. The 12V option is only if you are using the limit switches on that side of the board, but if you are using it to control spindle speed and for the outputs, it's best to use a 24V power supply, or the 24V output on the VFD.

The Mach 3 usb board requires an additional 12V power supply. How many amps would you recommend? Would a 1A wall adapter suffice.

Currently we do not know the values of the electronic components inside our drivers, since these drivers are supplied by our manufacture and replaced by them if a manufacture defect is present.

I recently had a mishap with one of my stepper drivers which resulted in a resistor being burned out. Would you be able to tell me what the resistance is for the R25 resistor inside the 6.0 amp driver?

Are you connecting this spindle and pokeys57cnc controller to a CNC? or are you simply wanting to control a spindle by itself?

Sorry, I thought that my question made it clear that it is for a Chinese 40W laser and I am replacing the original board in it with the 57cnc and I’m told that I need to buy stepper drivers and probably the stepper motors as well and I was asking which drivers and motors would be most suitable for me to buy to go with my already purchased from here 57cnc board

Additional Information:
Ps, I intend to use Auggie from Gearotics to drive the laser

I have a Chinese 40w laser that I was advised to get a pokeys57cnc for which I did. I didn’t realise that I would need stepper drivers for so was wondering which you would recommend as well as which stepper motors as I may as well replace those as well. Any advice is gratefully received, thanks

We typically use a 1/4 microstepping for lead screws, but you want to determine the microstepping only after you determine what resolution you want on that axis of the machine.

The formula:
Resolution is steps per inch or steps per milimeter

I will go over this using steps/inch:
steps = motor steps x driver microstepping
inch = the amount of travel with one full stepper motor rotation

In the case of our 1/2" 5 start 10 TPI lead screw, the axis will travel .5 inches with one stepper motor rotation.

Let's use 1/4 microstepping (4 microsteps for each stepper motor step)

Therefore:
(200 steps x 4) / .5 inches =
800 steps / .5 inches =
1600 steps/inch

Now let's use 1/2 microstepping (2 mistrosteps)

(200 steps x 2) / .5 inches =
400 steps / .5 inches =
800 steps/inch

Remember that increasing microsteps, the torque is also reduced, but the smoothness from the motor is increased.

All of our CNC machines can cut melamine. If your application (kitchen doors) requires large cutting area, then I would recommend the following machines:

- greenBull 4x (4'x8'), 5x (5'x10') or 6x (6'x 12')

- greenLean 4'x8' vertically oriented CNC machine

- Or our Fabricator Pro 4'x8' metal CNC machine

That depends on a few factors. In most cases, three 3.0 amp motors and drivers will not exceed 8.8 amps of available current. All of the motors would need to be at full torque to reach the 9 amps (3x3). This depends on the mechanical method you are using for each motor, and how you are using the machine. In most cases, only two motors are moving at a time (i.e. 3D carving where the X and Z are moving simultaneously and the y only moves to go to the next row). In traditional cutting profiles, only the x and y are moving simultaneously and the z-axis moves at the location it needs to start cutting the next layer.

With that said, it is ok to add an extra power supply if you feel you need more available current.

[51] Would the single 8.8A power supply be undersized for 3 6.0A Drivers? would you recommend getting another PS?

Yes, we can make a redLeaf system that has all 6A drivers for use with the 651 oz-in motors. We can also wire the electronics in a way that two of the drivers will use the pins of the same axis so that axis will drive two drivers and motors.

The 2.5 amp driver can only accept a power supply between 12 volts and 24 volts. If a 36 volt power supply is used for this driver, the main driver chip will exceed its maximum voltage rating and cause failure.

If you need to spin your motor faster, you can either use a more appropriate driver (i.e. 3.0 amp driver) or you can change the mechanical parts so the axis has faster travel.

Can I connect a 36V power supply to 2.5 AMP Stepper Motor Driver. On the actual driver it shows 12V - 24V, but in the description and data sheet it indicates that it can accept 8V - 45V. Will I benefit from more powerful power supply. Thanks

Yes, servo motors can be mounted on this machine. If the mounting dimensions are different than NEMA 23 or NEMA 34, then all you need to do is keep the center of the motorshaft with the center of the bearing location and locate the mounting holes for he servo you wish to use. Most industrial servos used for these machines share the same mounting dimensions and NEMA specifications.
