Ok, since movement is only really on one axis at a time and speed is not an issue I think I'll start with 3 stepper motor drivers on a raspberry pi, then I can get by <20€. If that doesn't work out...

image stitching will rely on matching elements in the pirctures.

small Nema17 steppers.

As the steppers only move some specimen around (a few grams to a few hundred grams at most) there will be practicially no load on the steppers. Mevement does not have to be...

Hello,

I am currently building the hardware needed for taking high resolution panoramic microscope pictures.

Due to the very small image sector and the very shallow depth of field I need to...

Hi,

Thanks for your answer, you really helped.

Speed is not an issue, small movement increments is in my application. To keep things simple I just bought a 5:1 geared Nema17 stepper motor, that...

Ok, i was able to open it up. At least parts of it.

Of the 9 Pins 4 go to the imit switches and 5 to the motor.
However on one pin there are two cables going to the motor. So I have 6 cables from...

Ok, now I measured it and it is slightly weird

I just cut apart a DB9-RS232 Cable to test.

So, I took a few pictures.

I took the thing apart as far as I got. Unfortunately the thing connecting the stepper motor to the spindle seems to be stuck (no taking apart even when opening the...

To be honest I am not sure. Their current models are with closed loop steppers, I just assumead that heir former models would be too. But now that you say that that assumption might be wrong.

I am...

Hello,

I bought a used owis precision linear table. It already has a (closed loop?) stepper motor attached.

It has a 9 pin d-sub connector, and I am quite unsure how to use that motor. What...
