I didn't change wiring. No need to.

Can you show/explain how you changed hot end wiring? Opened the printer but the wiring is confusing.

Can you release a version that uses the stock hotend?

The one with the hotend is the one you want. I have no idea if that's a pancake stepper (to save weight). I had to switch wires around on my A5 to the stepper to get it to work. That's up to you to check the voltages/coils. Beware that the quality of the clone E3D really sucks! The feed from the feed roller to the black inlet tube doesn't line up on most of them.

What are the benefits?

And can you provide a link to the direct drive?

Benefits? There are many but I leave that up to you to research and weigh all the comments for and against direct drive vs Bowden. It's very controversial since many people 'grew up' with ready-made machines like the JGaurora and CR-10's, where Bowden was a cheap alternative. They are happy with stringing and other problems. So to each his own. :)

Link to the direct drive? I don't know what you mean. Sorry.

I mean which hotend you used. The original Motor?

I used the E3D hot end that mounts to the Titan extruder. Then you use the pancake stepper motor that E3D sells, or in the case of the U.S. where I am, filastruder.com. The original motor is MUCH, MUCH too heavy and unnecessary and would only cause problems.

So it seems that you bought original E3D material instead of china clones?

Thanks for the information. Here it seems to work with the originial motor.

I got huge problems with the extruder motor, it always went to hot, even with the tmc2130 and current max 800.

Thats why I looking for an alternative the default system...

Yes, I'm familiar with that solution. You need the big, heavy stepper motor because you don't have the 3:1 reduction gearing that the Titan provides. With the Titan, you can use a much smaller motor BUT you must be aware that the Titan, whether it is the real thing or a Chinese POS clone is that you must not tighten the upper right hand screw that holds the face plate on. It binds the mechanism. It is a design flaw that, for some reason, E3D never fixed. That would be why the motor got hot. You manually turn the feed gear while tightening that screw and as soon as you feel any binding, STOP! You can use Locktite to hold it in place.

I did buy a Chinese clone of the Titan but the engineering sucks. The feed tube that runs up to the small feed gear is out of position, which makes the hot end out of position. It is a waste of money.

Thanks again,

which E3D hotend you are using? there are more then one ^^
