Anet A8 - How Hard is the Hardware Conversion?
-
@nhof I really appreciate that level of detail; very kind of you. Hope that I can contribute back here as well.

@phaedrux Ok. "It’s a UNIX system! I know this!". I mean, ok, between the wiring diagrams and the advice about polarity and the other guides, I think I can do this. Been costing out the AM8 as well. I'm going to take my time here and do this carefully. I'll let you all know how it goes but really blown away by you all!

@wilriker It may sound silly but its the "snipped off all of the original connectors and crimped the ones . ." that worries me. I have taken my Anet through a Bowden conversion and I look forward to the firmware challenges. But, I'm worried I'll get the wires messed up and ruin my board. I am not sure which things are pin-specific and whether the pinouts are different. Again, I know this sounds basic to you all. FWIW, I have a crimper and am finally comfortable with it due to a a super YouTube video (https://www.youtube.com/watch?v=-u1t7Cdf6RE). With that in mind, do you have any recommendations about the wiring? Where can I tell the required pin ordering?
This forum has been so friendly and helpful - I really appreciate it!

What type of connector do the motor leads on the AM8 come with? Some types with 2.5 or 2.54mm spacing can be plugged in to the Molex KK connectors on the Duet, at least as a short-term measure.
-
The Anet A8 Board uses 2.54XH connectors.

Thanks. In that case, it's possible to plug the motor and thermistor connectors directly into the Duet, at least for testing purposes. They only fit one way round, but that doesn't matter - the motors may run backwards, but that can be corrected in the firmware configuration.
The endstops will need to be rewired, because Duets use the two outer pins of the endstop connector for typical microswitch endstops.

@dc42 This is shaping up to be more and more do-able (he says knowing he will regret)

I went to the Duet from AM8 too. For the wiring, I re crimped all the connectors with the supplied crimps but I just sat and took my time and matched all the wires up one connector at a time, was easy to follow the wiring diagram for the Duet maestro with everything seeming easy to work out where it goes.
-
Anet A8 comes with 12v fans and 12 psu configuring this is not easy since board only supply's 5v I haven't found a wiring diagram for this in the forums.
-
Actually, you have an option on supplying the fans with your PSU voltage or with 5V. The jumper for selection is located under the fan connectors (V FAN JUMPER SELECT).

@veti - ok, I have finally completed my AM8 conversion. Yes, it took me this long! But, I double and triple checked everything, printed extra parts, etc. Wow, what a huge difference. It's a different beast now - fast, quiet, stable. I've just ordered my Duet and I'll be trying out all the advice and tips you guys provided . . . hopefully within a couple of weeks (traveling at the moment). Anway, I wanted to post here because others reading may want to know how impactful the AM8 upgrade is.

I got my first print with my Duet AM8 (thats what I call it now that my Anet A8 is an AM8 with a Duet processor). Thanks everyone for your advice and help. Especially, @nhof , your basic guide was so helpful. It may seem simplistic to you but topics of polarity are helpful to the novice.
It took me a loooooooooooonnnnnnnnnnnnnnnnnggggggg time but I took it slow as suggested. Also, I converted over to 24 volts in the process which meant new power supply, hot end, heated bed. Never thought I'd be Googling about Ohm's Law.
Learned a lot of things during the process and I hope to be able to help some others with the same conversion. Mostly, thank you all!

congratulation on building your own printer.
it does not matter that it took long. it matters that you stuck with it and learned new things on the way.

This thread outlines a fascinated journey. A picture will make it even more awesome.

Looks very clean, I mean the printer, not the desk,
and I like your choice of color.It uses a bowden extruder. I switch recently my printer (non Anet) to a direct extruder and got significant improvement in print quality.

So I won't be showing too much of my desks anytime soon if that is messy!
-
@jrwaters2 nice! Thanks for sharing your journey here (and also thanks to those on the forum that helped!).
-
@zapta hahaha - yes, my wife's patience has been amazing. Maybe over the holidays I'll get it cleaned up. Let's see
Want to to a little wiring clean up as well!

@T3P3Tony Roger that. What a great group!
