Congratulations good work, but me is concerned it's the 3.3 V, the controller is physical or by means of code? also I have 6560 and pulley of 20 teeth

Good job, it work great

did you try with biderection way?

It's not working properly with bidirectional. It is shaking too much and the image gets doubled. It looks like the elasticity of the belt may be the cause. I would need a system to adjust the belt tension. For now I'm happy with it, it's working perfectly with unidirectional. I'm planing to build a better base, from metal sheets and I'll try then to make it work with bidirectional too.

I just used a 3.3V regulator on the PE wire.

Nema 17 - 2.5 A motor
Driver TB6560 - set the microsteping to 1/8 - 1600 steps (this driver doesn’t have 1/4).
20 teeth pulley

I didn't use the shield (ordered one but didn't got it yet, I'm in Europe), I wired directly,

In the video I'm printing from AcroRIP, 1440x1440, white 100%, color 20%, unidirectional, 0.3s pause, with DuPont inks.


How you add 0,3 pause in acrorip?

In print dialog there is an option at bottom-left (at least in version 8.2.6). Now I'm not using that pause anymore, it was not necessary.

not understood well excuse my English, you add a controller physical of 3.3 v to the pin 10 of the code? or are the 3.3V from the code of andy

that difference is when you write LOW and HIGH, in the indent of
#define pePaperOut 165

#define pePaperIn 0

Yes, I added a 3.3V voltage regulator and changed analogWrite (from Andy's code) to digitalWrite.

This is a good idea to implement for the safety of your epson printer. All of our shields and AIO boards have a voltage regulator for the PE signal.

Could we not just use a 3.3v zener diode with respect to ground?

Yes, that's exactly what I use along with a 100 ohm resistor.
