Arduino with r3000

Sat Mar 11, 2017 9:21 am

Hello  guys 
i have converted an epson r3000 with the help of the spectra r3000 guy on youtube..
I have bought an already coded arduino for it but i have a problem.
i will try to explain myself as clearly as possible:

arduino uses:
2 wires paper push button from the printers back lcd
2 wires from pe sensor ( gray-black one, and middle gray one)
3 wires from encoder wheel sensor ( ground , encoder a, encoder b)

and it uses stepper motor for movement and 2 limit switches. one back and one front..one is NO and other is NC


The base without the usb cable plugged on the computer is acting fine..
both limit switches work..table moves and stops ok..

When i plug the usb on computer the back sensor is not working..stepper motor moves backwards for ever..

Now to print i do the following:

1. i remove usb cable of the pc
2. push the back button
3. push the back sensor
4. plug the usb on the computer
5. hit print on acrorip
6. remove my hand from back sensor

and then printer prints


Problem is i can not do this if the usb is plugged all the time on the computer

Please note i do not know programming and that is why i bough this already coded so if anyone can give a hint of what is going on i will really appreciate it.

Thanks

I can not know that...
as i said i do not know much about coding...

My only point that had to find my self other than others that were clear from this guy instructions was the paper push button pins of the r3000..
The guy did not know which are they on the R3000 and i find some info on the net but i can not be sure that they are the correct...
Does anyone knows what pins are they?
A photo would be great..

Thanks

If we don't know what board you have we can't give you an idea of how to set it up

ok this is understood but my question is:

How do i find the paper feed button from the back lcd pins of the R3000?

This is only what i am asking for

Changed laptop and problem solved

now i print and lcd shows :

Paper out.Load paper in the rear sheet feeder and press ok to start

which is normal 

Does anyone knows the two pins of the paper button on the back of the lcd of the r3000

Thanks

When you take the LCD assembly apart it's obvious which pins go to the paper button. I don't know off the top of my head but I looked before in the past.

i hope someone could explain this to me..

arduino uno ( programmed by some one else ) 
tb 6600 driver with nema 23
3 pulleys and two belts all xl

10 tooth in common axis with 18 tooth and 10 tooth on the stepper motor

when the driver is on 1/8 micro stepping the printer prints the image almost in double size..
when the driver is on 1/16 micro stepping the printer prints the image correct

problem is that on 1/16 the load and unload time of the table is very very slow according with the 1/8 micro stepping

the guy that sold me claims that it should be working fine with 1/8 micro stepping but it does not..

what am i missing here?

That would be in the code that the steps need to be changed. If it is preloaded code the person that sold it to you would have to fix their code.
