Link is bad, and sure of course you can replace it but I don't know how well it will work. I personally never buy clone 3D printer parts, especially electronics. There is so much that can go wrong already and replacing quality parts with cheap ones and poor quality control can just lead to a lot of headache. You may get lucky and get a good board that works well, but there's always a chance you get a dud and end up wasting time and money. The choice is up to you, but of course I can't guarantee your printer will preform as well as I claim if you don't use the parts specified in the BOM!

corrected link : AZSMZ 32bit ARM - AliExpress
I am also considering this. It offers 2 things, Dual extrusion which I really want to move up to, need to print PVA supports!... The other advantage is the replaceable stepper drivers... which btw there are better packages out there that include the drivers with the board and an LCD also if you should want one. As Andrew pointed out though, its not the official controller board for the Eclips3D and performance may be affected. One thing the Azteeg has that the AZSMZ doesn't is terminal connectors for the steppers, end stops etc, I like screw terminals vs header pin connectors... so if you do buy a AZSMZ you will have to contend with that.

Got my AZSMZ controller today, don't have my 8825 drivers yet, so just threw some a4988 drivers on to make it work. Seems to work as expected and doesn't have the same whiney sound as the ramps board that I have, that was one of my concerns, which is no longer a concern.

The AZSMZ does have headers for motor outputs but this is not a problem if you wish screw terminals instead. www.ebay.com/itm/5x-4-way-4-Pin-Screw-Terminal-Block-Connector-2-54mm-Pitch-PCB-Mount-MA-/111323191625So this board claims to support dual extruders? but physically I only see 3 high current Mosfets on the board, one for the extruder fan, bed temp and extruder heat. You would need another Mosfet for extruder heat, because you can't give up extruder fan or the bed heat, unless you never intend to print with ABS or nylon I suppose. The extruder for nylon would be at temp much greater than your PVA support filament. So is having the extra stepper driver enough to claim dual extruder support without having separate heater control?

So is having the extra stepper driver enough to claim dual extruder support without having separate heater control? Connection D8 is for your heated bead, D9 is for your 2nd extruder or fan, and D10 is for your 1st extruder. The AZSMZ has a controllable fan1 output. You can change the config to use this output instead of D9 for the fan. Line 98 of the config file. fan1 output is next to the sdcard slot. # Switch module for fan control switch.fan.enable true # switch.fan.input_on_command M106 # switch.fan.input_off_command M107 # switch.fan.output_pin 0.26 # if fan to D9 set 2.7 or fan1 0.26

I would think that if you wanted a second controllable fan, then maybe one could use the servo output of the AZSMZ but this would require a direct change to the firmware and an option in the text file to switch between fan/servo which currently doesn't exist.

+all3dprinting, How can you give up the extruder fan (D9) in exchange for another extruder hot end? I mean ok software-wise and electrically you can, but won't that cause problems with print quality and speed by omitting the fan, don't you need at least one fan? And you can't use servo 5 output for a fan because that's feeding the 2nd extruder filament.

I'm not giving up the fan for an extruder, through the config file I am changing where the fan is connected and therefore getting to use the D9 for the additional extruder. if you have not found it already, check out their facebook page AZSMZ Facebook. If you have questions on what the board is capable of or how to hook it up with desired configurations, they should be able to give you the answers you are looking for. Also a note to anyone who might go with this board, there are different versions, the newest is version 2.1. I do not believe that the previous version of this board has the fan1 option without additional circuitry.

OK Yes I see the fan would be coming out of P0.26, and D9 would be repurposed in software for the second extruder. Yes as someone has already asked, you need board version 2.1 or greater so you can drive the fan directly without an interface, so I guess prior there was no buffer or mosfet to handle much current on that pin.

I just finished replacing my printrboard on my 3uP to this board to see how it handles printing, just printing a calibration cube now...

Printed a case for the AZSMZ, you can find it here : _ Printed a case for the lcd also, control from this lcd works pretty well, although I have no basis for comparison.. does what it should and when you press the knob in you get access to the menu for manual control, selecting your print file from the sd etc etc.... anyways I can see myself using this more without a computer with the LCD hooked up... This was on of the test pieces I printed. I didn't change any of my configurations, there is a little droop in the bridging... all in all it seems to work... Here is some good info on getting your motor drivers setup correctly..

I worked the AZSMZ controller a lot since yesterday, did some lengthy prints... everything works great!, Time to model a dual head mount. got an led tea light from the dollar store and ripped it apart to fit inside.... brings this little pumpkin to life! Pumpkin from thingiverse.

So you are operating without any heatsinks on the Pololu DRV8825 drivers. Do you have an infrared thermometer to measure temps during a long print? Do you have a fan on them? What is the 4th driver you have installed? Are you using the same motors as specified in the BOM?

What is the 4th driver you have installed? Are you using the same motors as specified in the BOM? I am using heat sinks, on the drv8825 they are on the underside as there is a copper pad under the driver ic allowing the heat sink to draw more heat away. I do not have a fan mounted to the case "yet"... when I close it I will put on to keep the board and drivers cool. I do not have a infrared thermometer, but if I place my finger on the driver ic they are not hot. I have touched one that hadn't had the current adjusted and burned the tip of my finger before... this is nothing like that. . I could leave my finger there all day. The 4th driver that you see is A4988 driver 1/16 stepper driver... 1/32 drivers for the extruders doesn't offer any advantage from what I can tell... but I may experiment with this in the future. I am using generic 1.8a steppers... I have not placed my openbuilds order yet, waiting for the eclips3D kit to ship out first.
