Ramps 1.4 z axis is just buzzing : Not moving
April 15, 2018 03:27AM
I have made a printer using nema 17 and a4988 motor drivers in which x and y are working fine but z motor is just humming
I have changed the firmware,wiring,voltage and motor driver but nothing worked.

Reduce you max feedrate in configuration.h

The max feedrate of z was 5 default.
I've reduced it to 2 still nothing happed.
Is there any problem in the ramps shield???
Plz help me

A max feed rate of 2 should work for z.

do you have micro stepping jumpers installed under the pololus?

have you enabled eeprom? (if so you need to reload eeprom from firmware)

Don't just tell sh**t. I am just asking for help. If you think you know about this then please tell me or just GTFOH.

Only three possibilities left.

1) the load is to great for the steppers
2) you have miss wired Z (or a wire is broken)
3) dead stepper drivers.

You have X and Y working, so unplug X stepper motor and plug in each Z stepper in turn and tell the machine to move X, to test out each Z stepper

NB do not unplug steppers while the machine is on, that will kill the stepper drivers

The stepper drivers are working fine in x and y and I have used all combinations of wirings but nothing helped.

try the ramps test firmware

[reprap.org]

this will move all axis back and forth. no configuration needed, this will eliminate any potential firmware related configuration isues

NB will also turn on MOSFETS, so make sure anything that will heat up is disconnected

I ve also tested with test firmware but still nothing.
But one more thing there is a short in the pins of z slot.
Is that could be problem.

Yes that would be an issue...

There is a special thread for this controller. Why people can't post at the right place ???? Do they really do a search ?

Take a chill pill, in fact I suspect you need half a dozen in suppository form.
