Stepstick trimpot?
August 23, 2011 03:29AM
Hi,
I'm pricing the stepstick right now, and I'm wondering what trimpot I need to use.

I believe it is 3mm, but I don't know the proper resistance.
Thanks!

I think it's shown on the right hand side of the schematic here as 20k [reprap.org]

I just spoke to Joem and it is a 10k trimpot. I am going to put together a Mouser Project BoM for the StepSticks here in the next few days.

Cool, thank you very much!

If you want something to start with, Here is my mouser parts list with no extras.

I'm sure I didn't pick the optimal components, but it's a start.

And mouser doesn't carry the A4983 or A4988

I've amended my earlier, wrong post. So, is the schematic wrong, or did I read it wrong?

I think you read it wrong. The current schematic just has Trimmer labeled for the trimpot.

Ah, yes, I see what I did. I looked at the resistor above it. Doh!

Hi Legot -

Do you happen to know what the following parts are:


J1E CLONOLU CLONOLU CLONOLU pololu-allegro 1
J1X CLONOLU CLONOLU CLONOLU pololu-allegro 1
J1Y CLONOLU CLONOLU CLONOLU pololu-allegro 1
J1Z CLONOLU CLONOLU CLONOLU pololu-allegro 1

Also I assume the S1E and the other S1/S2 parts are 0.2 Ohm correct?

Thanks!
