X, Z motors not working, Y and E does
Hello everyone, as the title of this topic states I'm having some troubles with getting my stepper motors working. I've wired up everything to RAMPS 1.4 according to [reprap.org], uploaded a test...

Nevermind, found out what was wrong. Very stupid of me, apparently Ramps didn't fit well on Arduino's sockets. Now all of the 5 motors are working! :)

Thank you guys for the link. I have applied the mod and made some videos. All tests were made with 1/8-microstepping and the same program on the Arduino, I just swaped the drivers. Here is the...

So pretty much lets just ignore the frequency from the micro-controller. It sounds like I have the math right for figuring out what torque I need to produce from the load end of things and now I just...

Tried posting a couple days ago but the site told me my post was spam and I forgot to retry.
View ArticleRe: Microstepping not constant
If you are getting noise from your steppers try upping your PS voltage. The switching frequency is dependent on the voltage so 24V should bring the frequency outside of hearing range. This has made a...

@jzatopa: I'am not using my steppers for printers. I´ve build a pan/tilt-head, which can move my camera. Going to 24V is not possible, since it is a portable setup which runs on 12V-batteries. I was...
View ArticleHow do I calculate what size stepper I need
So I am building a larger printer. And I am using 3 long 640 mm 16mm rods for a "Y" axis with 3 long pillow block bearings to go on the shafts. Those blocks will be moved by a motor. That is the "Y"...
View ArticleStepper motor breather hole.
The leads exiting a stepper motor expose the internal copper wires. Is this a breather hole. Can I apply silicone to block the hole to prevent dirt from entering. I suspect it's not recommended, but I...
View ArticleRe: Stepper motor breather hole.
I would specifically use high-temp silicone. Or if wire isolation is the problem, maybe heat shrink tubing.
View ArticleRe: Stepper motor breather hole.
Tks NoobMan, I was going to use automotive red high temperature silicone. So no issues with ozone if it's sealed up. I was thinking of letting the motor run for awhile to evaporate any solvents that...
View ArticleRe: Stepper motor breather hole.
To stop dirt from entering there's no need to make it airtight. Airtight isn't a good idea, because warming and cooling will expand/shrink the air inside and with an airtight venting hole expanding...
View ArticleRe: Stepper motor breather hole.
If there is room between the wires and the opening they come from, i guess that is perhaps because they decided to use lower gauge wires, or a rubber ring there may be missing, but otherwise the gap...

QuoteNoobMan You cant really seal the motor because it still has opening at least near the shaft if not also on the back... Most of mines have opening on the back so i have some small patch of tape...

hi Xiazhou. How did you solve the problem. Even i am facing similar problem. My extruder motor is not working. pls reply.
