Took some time to figure out how to use Eagle-3D, but I like it.

Anyone know where to find a 3d file for the 3 pin resonator

If you are using V1 software make sure the enable pins are at 5 volts.
If you are using V2 software make...

Here are the new files with the modifications I mentioned.

I already am using them on my current setup so I just thought I would stick with them as they see to be working OK.

I compared the scematic to the one on the Linistepper site and they look the same, only the parts are in a differnt place, so should work the same as the orignial linistepper v2.




The motors...

The 100nf is a "decoupling capacitor" it helps protect the micro from lockup or glitches and should be placed as close to the vcc and grd pins of the micro as possible. With drawing more current I...

I am going to try and drive some 3 amp/ phase motors.
I made the traces larger so should take the current.
Added a 100nf cap on the pic and split the ground traces.
Changes I am going to try are...

I modified Patricio Oholeguy eagle files to reflect v2 of the linistepper and made some minor changes.

This is for homemade single sided board.

I have not made them yet so there may be...
