motors just clicking

I have and arduino with gen 2 electronics, and when I run the firmware test the motors will move on the reprap. However, on the host software they just click back and forth, thoughts?

Did you check what the feedrate and steps per mm are set to? If they are set too high the motor won't run.

They are at the default

feedrate x,y 3000
z, 50

the steps per mm are about 8 for x,y

320 for the z


What should they be?

Those values should be fine, though you can try turning them down some. Anyone else have any ideas?

There are quite big diffrences between machine types and the host software settings.

The default settings are set up asuming you have a Darwin with the belt drive.

The settings required for a threaded drive need to be set based on the threads per inch / mm and the number of steps per mm or inch.

Using the settings for a belt driven darwin on a MCwire set up will give this effect. Step pulses too fast for the stepper to move.

So for any mechanical configuration other than a that of the standard Darwin.

You must provide your own details of the drive parameters.

The maximum accelaration parameter will also need adjusting to a slower acceleration rate as the clicking you are heaing will be missed steps.. Ie too fast for the stepper motor to respond/work

I have a darwin with belts, but I took my motor off of it completely and it's just clicking.

Sorry I'm new at this, but which specific thing in the preferences should I change?

Your problem could be a diffrent problem altogether the example/stepper test sketch uses diffrent controll pins to test the stepers.

So you should check the Pins.h file and make sure you have the correct pins used for step and direction if these are ok then.

You will need to slow the step rate in the parameters.h file.

To slow the step pulses down you need to adjust the feed rate for X Y and Z by making the numbers smaller in an erlier post you you indicated it was 3000 was this a typo?

#define FAST_XY_FEEDRATE 300.0
#define FAST_Z_FEEDRATE 50.0

If its 3000 set it to 300 if its 300 make it 150

You can half the feed rate untill they work then slowly increas to get the best feed rate.

If your motors are clicking back and forth it means you dnt have ur sequence right..standard sequence is ABCD from the software but I guess your motor should be an ACBD which is why its clicking back and forth.

It could also be the timing/length of the step and direction pulses sent to controll the motors.
