Re: Stepper motor assistance
To spin the wheel faster, you would need to increase stepper current if possible. Or adding some kind of acceleration control would help. Don't know, if your hardware offers such options? Both would...

The K179 is an old constant-voltage design for driving unipolar stepper motors, and its step pulse generation is fixed frequency. The first step to getting higher speeds is to ramp up the speed...

Thank you for that information. Do you know which model of Arduino would best suit this?
View ArticleRe: Stepper motor assistance
If you have no experience of Arduino, then I suggest the Leonardo or the Uno.

Hello Olaf, You mentioned the k179 driver has a step-generator chip and to remove it. Can you tell me where it's located in the attached pic? Thank you.
View ArticleRe: Stepper motor assistance
According to this schematics you can't remove the chip because it also takes care of stepper-direction. But as dc42 suggested, you can use the external step input. If I were in your shoes, I would use...

I ordered the arudino uno. Can you recommend a different stepper motor driver instead of the K179?
View ArticleRe: Stepper motor assistance
Olaf suggested a different stepper motor driver, but I didn't yet for two reasons: 1. Without knowing the specifications of your stepper motor, I can't say whether or not you can use one of the...

The pinouts on the motors are different between the extruder and all the other axes. Try this: Swap the center pins on the black connectors for both motors. Should clear it up. Another fix for...

Hey Mike, Thanks for your reply. I followed your directions, and it solved my problem (I did have to flip the black connector 180 degrees to correct the travel direction). Now, being the engineer that...

I'm sure you meant 0.2 and 0.1 ohm. :) But anyway the 0.1ohm variant allows to set a higher current value than the others. That doesn't mean the driver can stand this current, so be careful not to...
