Then plug the new one in its place, the pins are labeled on both boards so just match them up.  Then open EEPROM in RH and double the steps/mm for E:  that's all there is to it other than adjusting VREF on the new driver.

1. Can I install just one for the E axis?
2. Do I have to make any software changes?

any reasons for me to avoid the higher priced but 1/32 operation....that's my inclination right now is to get the Stepper drivers - DRV8825.

Both can be found at http://www.printitindustries.com/

Azerate: thank you for your eeprom settings, this seemed to settle down one of my problems.

I'm still having difficulty with one of my drivers.  as i move it between the E and Z axis this problem follows.  I've tried to adjust the pot, but I'm not getting improvement.  I think I need to purchase a replacement or at least try that low cost option.

how do I look up that item for purchase?
what sites do ya'll recommend to buy from?

Also I would not attempt to plug  in or unplug a driver to a board with power for the same reason.
drivers can ba had for about $ 2.00 each if you buy at the right places but why risk damaging things.

Ward:  both, I switched motors and the little drivers
Tin: yes, I'm being careful when touching the board.  it's humid enough now that I'm unlikely to transmit static.  But I'm being careful and I don't believe that I've shocked my system

I'm ruining this thing as I touch it!!!

Make sure power is  off when swapping motor connections or driver boards

I use a DRV8825 1/32 driver and my numbers are as shown below
http://i.imgur.com/OuxrsWL.jpg

If you have stock A4988 1/16 drivers, then instead of 855.80, try 427.90 for E.
If this doesn't fix it, try a new motor here
If you buy a new motor for testing, I do not recommend the Nema 14 or the Nema 17.9 degree. If you have any questions or confusion, please contact sales@printitindustries.com

Looks like the drivers are removable.

I switched the E driver with the Z driver.  the problem moved to the z motor, but the problem did not go away from the E motor.

I'm ruining this thing as I touch it!!!!

I feel like I need to get a new board, but that may be overkill.

what are your ideas now that I've F'ed this up more?

here are my eeprom settings

You may be able to swap stepper drivers depending, and drivers of poor quality can behave in a very peculiar fashion(s). Tin does have a good theory on traces, but unlikely if everything was working fine before the change. When I upgraded to the Titan, I also had motor problems, but they were for completely other reasons and acting different than your issue. This doesn't help, but I just wanted you to know you aren't completely alone in this.

Also, what are your current EEPROM settings for E and your extrusion speeds? When I retract more than 25mm, I get clicking, but this is due to speed settings. Did you change the firmware recently? Also, what motors are you using? Do you have a link?

I have a bad board or bad program input!?!


if the problem ! is coming from the board you may have a broken trace  a cold loose solder joint or a bad driver.      Can you swap drives between axiz.
