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:
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.
