I've made several codes seperatly and now trying to combine them. The LCD I can manage, this works 'combined'. But now when I add the stepper to the IRremote/LCD code it's acting strange.
It seems as if my IR is recieving 'another button' while it's at actionstate0 executing a stepper command.
Could there be a conflit in my libraries or something?
Wiring etc is good. It works with the same pin locations when I run the seperate codes to test.
Code pasted below, feel free to have a look.
Work in progress so a bit messy perhaps...
Thank you

Edit : I'm powering the stepper seperatly using the tiny power board. Ground is shared.
Edit2 : When I run just the stepper code, it works as stated above.
What I notice when I run the 'combined' code :
The mini power board flashes very gently even when powered off. Yet the Arduino has no 5V+ connection going anywhere.
Also, the C&D led's are constant on the stepper board but A&B flash and go off. Instead of keeping on and turning the stepper...
I find your code difficult to read. Please use the Auto-format tool to indent it consistently and please add a little white-space between sections
An explanation of how the code is intended to work would also be a big help. Comments like " // ### Button 1 -> Max weight" don't mean anything to me.
Also, I don't understand this and I don't have your hardware so I can't try your program
It seems as if my IR is recieving 'another button' while it's at actionstate0 executing a stepper command.
Could there be a conflit in my libraries or something?
What exactly are you seeing that makes you think that?
So the big picture is a 'remote control' button is detected and code is executed. I added a few comments and spaces as requested. The goal is to make a control to simulate a scale.
For now, I want to be able to set the stepper to go from 0% to 100% and in between. 0% would be 0 steps, 100% would be for example 5000 steps. So if I want to load my scale to 50% it would go to 2500 steps later on. The stepper is connected to a potentio meter, which is then connected to a weighing terminal.
As you can see on the video I've made, the remote reciever and the stepper motor print is blinking when the code is supposed to be executed and something beeps shortly. No idea whats going on...
Video : video 1550676315 - YouTube
Same hardware works if I run a stepper motor 'example sweep' code.
Thank for your efforts.

You have still not described the system in a way that means anything to me. Your video is commendably short, but, again I cannot understand it.
As far as I can see you have only one line in your program (line 153) where the stepper motor is intended to move and that line is within an IF statement that is only true when ActionState == 0) && (Seconds >= 1. However I have no idea whether you are creating the conditions for that to be true.
A couple of other things ...
The standard Stepper library uses blocking code so it will do all the steps before allowing the Arduino to do anything else.
The same is true of the delay() function
Taking those together I would not expect your program to be responsive to incoming IR data.
I suggest you make a copy of your program and strip out everything except the minimum needed to receive an IR command that causes the motor to move. That will make debugging very much easier.
I've found a bug. This part "myStepper.setSpeed(rolePerMinute);" was not in the setup void.
Its all working now. Still rather strange how this was affecting the whole thing in the way it did.
Been noticing you're a friendly helpfull person, so I did upload a longer video (and it's darker now) that shows what was going on. The remote reciever keeps flickering like someone would push a button.
If you're really interested I'd try and explain the whole concept I'm building.
