Re: Driver setup
Thanks Olaf, It's very clear, but just to be sure; The change in resistance just makes the tuning different, but I dont have to change the setup-files? And actually I meant 0.02, but that doesn't mean...

The steppers will always hum when the drivers are active. So a brake on the axis and disabling the stepper drivers is mandatory. A worm gear can also act as a break, when the gear ratio is high...

Re: Stepper motors in sound sensitive enviorment
Thanks for replying. I'm using a linear encoder Link. These encoders working conjunction with this controller Link. This is a digital encoder. It can be controlled via either RS232 or RS485. The end...

I think its in the nature of a worm drive to be 90° angled. I can't recommend a brake, since I don't know the weight of your setup. Anyway it should be spring loaded with a solenoid actuator. A...

Quotethe_digital_dentist If you run the Z axis up and down without the servo plugged in, does the controller still reset itself? No, it only happens when the servo is plugged in.. Just updated marlin,...
View ArticleRe: Restarts when moving steppers
I think your problem is poor power to the servo, or a bad conection to the servo ground wire. How are you powering it: what exactly is the step-down you mentioned?

Reading vref from DRV8825 X axis, originally set to 1V. When activating motors or heating extruder, the vref increases, and stalls the motors. What's wrong? Video showing the problem: [youtu.be]

I've experienced a few freezes when I turned the encoder too fast or too much with 1.0.2 Marlin version. ( some kind of stack overflow? ) Especially worse on Z-axis, because each step is limited to...

View ArticleRe: Nema 23 cant go fast HELP ME!
You can't get a stepper to go that fast, even with no load. You'll need a different type of motor. You can do full steps with that driver, but at 2000 rpm you need 400k steps per second. I don't think...
