looking to build a machine

[AutoWiz]

For strength and holding torque and the promise of no skipped steps, you will want taller stepper motors that will have multiple rows of steps for the coils to hold in place. Also the drv8825 stepper drivers are the most robust and can handle the most amperage. This is how you should be looking for strength in your stepper motors. Also 24v vs. 12v. will give you a lot more holding torque.

And of course once everything is together fine tuning your stepper drivers with a dvom and the pot on each driver will always bring you to the results you are looking for.

I don't just build engines. I take whole cars, strip them down to their last bolts and build back a whole new car, and after I'm done building, I get to tune it by way of re-writing the pcm, and then strap it down to the dyno I installed and find out what it is worth. With 15 current a.s.e. certifications, Here on the internet I am the AUTOmotive WIZzard. But in the real world during business hours, I am the corvette expert. Website:

And here are some tools I own for the auto industry that get to help me here but none of you will get the joys of experiencing:

That verus edge costs as much as a new car. IT requires $1,000 updates 2x a year. And I own it personally. It is the peak of my career. I bought and traded in 4 different generations of scantools and paid heavily over the last 15 years of my career to bring me to be able to own such a tool. But just think for a minute, if you will, about the possibilities of a 4 channel lab scope tied to windows. The norm for the auto industry is 2 channels. But I can look at all 4 stepper motors on a 3d printer simultaneously and watch a printer work through its pwm commands or step counts. A resolution much of the rest of the world doesn't even know about.

At the end of the last link there is also another tool that I have that I get to use on the 3d printers. My snap-on thermal imager. How do YOU measure stepper motor temps? 1 at a time? with your finger? like mom checking her child's forehead? Or do you require precision in your knowledge like the AutoWiz?
