Re: Adding another stepper motor
RAMPS has a huge number of spare pins to work with, its ideal for this kind of further development.

Hi, I did try to recycle used motors not taking too seriously the resistance (4.7 ohms per coil) and just connected them to my 4988 drivers using 12V. The result is burning hot motors that after a few...

no the inductance is too high they may be torquey but they wont be able to spin very fast. look for something with less than 10mh of inductance.

I am having trouble getting my stepper motors to move, they simply hum when pots on driver is turned towards the minimum and click and lock when the current is turned up. I am using ramps 1.4 (reprap...

... re-check correct pin assignment and clock speeds - 'humming' is either not enough current or too high stepping rates ...

Problem solved!! Seems like both the firmwares i tried were sending the motor a signal they didn't like, i tried the ramps14 test code and it worked so i tried the official version of marlin and they...

those have too many amps, they should be between 0.5 and 1.5, sorry for the delayed response. although qu-bd cannot make a decent hot end, they do have very good motors, [store.qu-bd.com]. they are...
View ArticleLower Voltage But Louder Motors?
I've been using a set of Shinano Kenshi STP-42D3018 stepper motors for the X, Y, and E motors in my RepStrap that are 8.8V 0.64A 11.6Ω bipolar and 5.2V 0.9A 5.8Ω unipolar. I've been using them as...
View ArticleRe: Lower Voltage But Louder Motors?
The loudness of the motor mainly comes from the fact that current through coil is turned on and off in frequencies bellow 30 kiloHertz. The sound mainly goes away when microstepping as this frequency...

It's possible I haven't been getting great micro-stepping and this is adding to the vibration. The G3D stepper drivers that I use include a voltage pot and also a separate 30K trimpot, described this...
