Looking for a simple few things

[MartinM-dev]

Hi

I'm a newbe in Python and i have lot things to learn.

I'm trying to move a trolley on rail.

When i start, i need to drive the trolley to the "Zero Position" and set this position to 0.
I don't know how to set current position to zero.

I also want to change the speed of my trolley or better, set a time to go reach the target position.

i hope someone will help me.

Thank you

You should probably start with a much more basic driver than this one. try a google search like

Hi, I too would love to be able to use your library, but am having a little trouble getting off the ground.

I'm looking to control a few steppers via artnet, so I need to work without the webserver part, but I can't seem to follow the program flow enough to instantiate the multimotor class without it. If I can get this and also instantiate a couple of stepper objects based on a json definition (e.g. motorpair8825.json) then I should be all set.

Any help would be much appreciated, otherwise I'm going to have to start from scratch.

Thanks

unless you need the ultimate performance that this library provides, you are probably better sticking with one of the standard adafruit or similar libraries as I don't have the kit anymore to check or update this library to support it.

Hi @pootle, thanks for such a quick reply, I have one more question. You haven't put any license up, if I do succed in getting this up and running would you mind me rehashing it into a library for others to use? Obviously with full attribution.

Your code appears well commented and it's a very elegant solutiion so it would seem a shame not to as there really doesn't seem to be anything even close that's out there.

oh! early days when I did this one. Absolutely free to do with as you will, attribution not necessary, but would be nice. At the time I did this, loads of people were claiming good stepper driving from a pi / python was impossible, so of course I had to do it!
