I'm getting ready to start my 7th or 8th project, but this will be the first real one. My plan is to use a couple of stepper motors to lift some sort of spring pusher and have it hit the project chassis to make a knocking sound. The stepper motor will rotate 180 degrees and have an extension arm that lifts the push rod up for the first part of the motion, then at the end of the motion the push rod will release from the arm and fall back down to the chassis. I will be adjusting the tap tension while in prototype mode. Can anyone recommend a good 5V bipolar stepper motor? I found a site ([url=https://www.oyostepper.es/]servomotor[/url]) that has good bipolar stepper motors, but I don't know how to choose the right motor. Please give me some advice! Thank you!

I have a NEMA 34 stepper motor (https://www.oyostepper.es/category-9-b0-Motor-paso-a-paso-NEMA-34.html) with controller for a machine I am building. The stepper motor does everything I need it to do except for the holding torque I need. I need about 10 inch pounds of force, 24 inches tall, and my current motor can only pull 3 to 5 pounds. The motor needs to be bi-directional, variable speed, and be able to adjust the travel distance 12 to 15 inches on either side of center. Lastly, weight is a factor, and I need it to be as light as possible, preferably under 10 pounds.

Good day! I got the machine assembled and all axes move freely. I'm an old school Mach3 enthusiast. While doing some initial testing tonight with my stepper motors (https://www.oyostepper.es/goods-77-Motor-paso-a-paso-Nema-23-bipolar-18-grados-19-Nm-28-A-32-V-57x57x76mm-4-cables.html) I noticed that the motors get very hot. For other CNC builds I've done using wood or aluminum, stepper motor heat has not been a problem. And for those machines that's normal for the motors to get hot. With the PLA mounts, the heat really bothered me. I put a thermometer on the motors and after about 10 minutes, the temperature was about 110 degrees Fahrenheit. I can imagine that the RAMPS setup would run cooler, but I've never played with that arrangement and I don't know. So how hot do the steppers get in other people's builds? Thanks,

Hello, I have a Nema 23 stepper motor (Bipolar 1.8 deg 2.4Nm (340oz.in) 1.8A 4.95V 57x57x104mm 4 wire) https://www.oyostepper.es/category-7-b0-Motor-paso-a-paso-NEMA-23.html with a tb6600 controlled by an axbb-e. Lately, this driver and motor have been sending steps but the motor just locks up. I checked with a multimeter and it seems like the driver is sending all 24v to the a+ and a- coils of the motor. Any ideas? Please let me know. Thanks!

my motor runs very slow but steady, however, when I increase the speed from 10mm/sec to 11mm/sec it starts to vibrate, or just make a vibrating sound, not moving at all, then it makes a high pitched frequency sound. I tried using the 3 driver boards that came with it, and 3 different motors, cross-wiring them as I went along, so I tried the same method and it worked for all 9 times when switching, I'm not sure if this is due to insufficient "grounding"? Because I'm using the controller board GNDs from USB to PC, and then splicing them to all 3 driver boards I'm not sure if I can send those GNDs from the driver boards into a large piece of metal? Like...the frame of a CNC? Because I'm making them out of metal? Link to my stepper motors: https://www.oyostepper.es/category-7-b0-Motor-paso-a-paso-NEMA-23.html Thanks so much for your help...

Arduino newbie confused I am taking over a project that involves moving an object using a threaded actuator rod. We are currently using a NEMA-17 bipolar stepper motor, but the project requires us to replace the stepper motor with one designed for UHV, and I have at least an AML D42.3, I would like to use an Arduino Mega . 2560 to control a UHV stepper motor. I think this would be a fairly direct replacement for the current Usongshine motor, but I am not sure if I can drive the motor with an Arduino. Any ideas would be greatly appreciated!

Hello, Looking for some help with a rather unusual problem - I'm using fairly large stepper motors, but can't currently get them to work. The motors I'm using are on this page: https://www.oyostepper.es/goods-88-Motor-paso-a-paso-Nema-23-bipolar-18-grados-3-Nm-42A-57x57x114mm-motor-paso-a-paso-CNC-de-4-cables.html I've wired the motors in a bipolar parallel configuration according to the diagram. I'm using A1 as positive, A2 as negative, and B similar. When I start to home the unit, the motors will jerk a bit as if they're about to move, but then stop. I can move them manually afterwards, so I know they're not idling. I plug them into the extruder driver, and I notice the same behavior - but it will just jerk a bit and refuse to move (only on my first try, after that it won't move until I reset the unit).
