If your motor spec call for 5.5 amps, it is best to set the driver for the setting that matches that spec, or the next lowest value. This will allow the motor to run within its designed characteristics.

For a stepper motor that requires 5.5 amps, would you recommend setting the stepper driver to 5.43 or 6 amps? Better to go lower or higher?

The NEMA 11 16.7 oz-in motor is a dual shaft motor and the rear shaft extend 15mm or .59 inches.

Is the NEMA 11 Stepper Motor (16.7 oz-in .185" dual shaft) 0.67 Amps actually a dual shaft stepper motor? The drawings only show the shaft coming out one side.

The NENA 14 motor is paired with this driver and will work very well: https://buildyourcnc.com/item/motion%20electronics-steppermotordriver-newbiehack-Motor_Drivers-2!5_Amp_modular

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)

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.

[810] Is this a closed loop motor? What is the recommended driver and power supply for this stepper? Would you recommend using one power supply per motor pair or one power supply per motor?

Yes, we offer a CNC electronics assembled package called the redFly, redLead and redSprout. If you already have a computer, I would recommend the redFly. You would still need to add connectors to the ends of your motor cable.

Yes, we have the NEMA 11 16.7 oz-in stepper motor with dual shaft in stock.

Do you have it in stock? (NEMA 11 Stepper Motor (16.7 oz-in .185" dual shaft) 0.67 Amps)

Yes, the 651 oz/in motor requires a driver that is compatible to the motors (the motor will draw 6 amps max and the driver paired with this motor will be able to allow for a 6 amp draw). I would also recommend a 36 volt power supply for better high velocity performance.

will the 651 oz. stepper motor you offer require a different power supply then for the original stepper motor I perched from you a few years back? I think it was a 24 V. unit????

We just received our new inventory of motors and that specific stepper motor ski came back with only one shaft. I’m not at the office to look at this inventory, so if that is true, they will all be single shaft. We may have other stepper motors with included rear shafts, but I will have to see on Monday.

If I don’t have the double shaft, we will provide a refund upon receipt of the motors. My apologies for this error.

Additional Information:
Hi, I'm sending these motors back today. As I understand you, you might have some motors from the previous lot still in stock, and these would be double shaft but otherwise you don't have any and won't be getting any. If you do have two double shaft versions of this motor please send them; if you don't have two of them please let me know--today if possible--so I can start looking elsewhere. Thanks, Ted Armen

we just received two nema 11 stepper motors per our order--USR2-2, however they are single shaft, we need double shaft, I thought that's what we ordered. We're sending them back, let me know if you do have the double shaft version and I'll try again to order them. I notice the model number on the motor ends in "A", where the packing slip shows "B".

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

Any of the following power supplies will be fine for powering the Mach3 USB controller:

however, the limit switches do not need high current, so the following power supply is sufficient for the task of connecting limit switches:

Consider the loads on each axis when choosing appropriate stepper motors. If your holding torque is maxed out at roughly 16oz/in (1lb/in), then you could use the NEMA 11 or 14. Also consider the shaft sizes and current ratings when choosing drivers that pair with the motors.

I am planning to build a scratch CNC machine to do rotary engraving on writing pens. Can you recommend the parts I would need? I'm thinking NEMA 14 (11?) and 3/8" acme rod. Not sure which linear motion to use. I have an old lathe to use for the 4th axis.

Are you able to install a newer version of Mach3? If you are worried that your configuration will be lost, you can save the configuration by copying all of the XML files from the Mach folder. The XML files contain all of the settings that you applied in Mach3. Just in case the XML files are not compatible with the new version, make sure not to erase the current Mach3 that you have on the machine.

What material is the 0.1mm and 0.2mm board?

Additional Information:
Steel sheet


Additional Information:
Steel Sheet

Additional Information:
Thanks for the response. CO2 lasers unfortunately cannot cut metallic materials. Metals are best cut with other types of lasers, or by using oxygen assist. The oxygen assist method is not encourages as the combination or CO2 laser and oxygen is very volatile.

Additional Information:
and I can not do this laser to cut the steel plate, but instead of the CO2 tube I put the oxygen tube, or do not I know ?! Do I have a chance in the products on the site to create a laser for 0.1mm and 0.2mm steel sheets?

It is usually best to mount the motor in a way so it is spinning clockwise to avoid confusion.

Additional Information:
ok, but lets say the motors turn clockwise. if you mount it to ether side of the y axis it will pull to that side so what are the correct positions of the stepper motors. is it the left side or the right side of the y axis and also is it the front or back of the x axis?
