Topic: I just got my new Azteeg X3 and I have some questions.

I know, most of this has been covered in other threads but I just want to get this out there while it is still fresh in my head. I have a new Azteeg X3....

I was using the g-code controlled extruder fan with the MOSFET, do I still need the MOSFET and where should I plug in for g-code controlled stuff as well as power for fans that run all of the time? For example, fans for the motors.

Can I use the stock power supply just to get it all working? I have the Dell power supply that everyone seems to like, how can I add a switch to that?

The kit came with all new wires for motors and whatnot, should I replace them or just keep what is already in place?

When I do go out and get wires for the power supply, what gauge and length should they be? Keep in mind I plan to upgrade the heatbed. 14 gauge?

Is there a way to get enough power to run a Raspberry Pi? I would like to get power for it directly from the X3 just to keep it looking clean and not have to use an old phone charger.

What version of Arduino should I be using?

I'm sure I know where to find firmware settings for all of this but is there anything special about the firmware that I need to know about?

I know, this is a pretty tall order but I have been without my printer for three weeks and I want to get this right.  I'm sure I will have more questions but I think this is all for now. smile

Re: I just got my new Azteeg X3 and I have some questions.

Ian has a really good post on this somewhere on this forum.  You can run your fan from the second extruder header or there are other options as well.  No need for extra hardware.

My Solidoodle 2 is the deluxe model or whatever and I use the same power supply it came with.

If I remember correctly the existing connectors were pinned out the same as the Azteeg except for the endstops which needed new connectors added.  I only changed what I had to.

I hope that helps.  I have no answers to the rest of your questions.

Re: I just got my new Azteeg X3 and I have some questions.

The set of pins next to the thermistors are for fans and the like.  They are D4 D5 D6 and D11, with a 12v pin below and a 5v pin above so you can pick whichever one your fan needs.  If you use these, put the pin you used in pins.h.  If you wire the fan to the terminal meant for the 2nd extruder, you would choose pin 9.

For LEDs and always on fans, you can put them into the power terminal.   There is another pair of holes labled Aux In at the corner next to the fuse.  You can add a small terminal block there as well and use it instead of the main power terminal.

For power, I got a 12v 30A switching power supply on Roy's recommendation, and used a cord that I cut off of a dead supply.

Here's the thread I made when I upgraded - http://www.soliforum.com/topic/377/upgr … azteeg-x3/

I just found out that the 12v, 10a stock PSU will not work with the Azteeg X3.

Re: I just got my new Azteeg X3 and I have some questions.

I have been looking all over for more information about this board and what to do when nothing seems to work right. I use the Marlin firmware, right? It just needs to be modified, right? Is there some other firmware I should be using with this? I can run the test code, which probably was not a good idea because the endstops didn't work even after rewiring and firmware changes. I don't know where to go from here.

Re: I just got my new Azteeg X3 and I have some questions.

Which changes did you make to the firmware, and what are the endstops doing?  Which set of pins did you plug them into?  The front set of endstop pins are for Min endstops (at the 0 coordinates of each axis) and the back set of pins is for Max endstops.  The solidoodle has endstops at X and Y Max, and Z Min.

I couldn't get the existing plugs to fit onto the back pins, so I plugged them all into the front (Min Endstop) set then changed the firmware to use those front pins for Max Endstops.  In Pins.H I switched the pin numbers for X Min and X Max endstops and switched the Pin numbers for Y Min and Y Max endstops.  Since the Solidoodle already has its Z endstop at the Min (0 coordinate) I left that one alone.

If the endstops are acting like they are always on, reverse them in firmware.

Also make sure that common from the endstop (the pin next to the hinge) is going to the middle pin of the endstop connector and NO (middle pin on the switch) is going to the left pin of the endstop connector.

Follow the directions posted elsewhere for updating firmware.  When it is open in Arduino, first go to configuration.h and  change
#define MOTHERBOARD 62
to
#define MOTHERBOARD 33
go to pins.h and find the section that starts #if MOTHERBOARD == 33 || MOTHERBOARD == 34
Switch the Pins between Min and Max for the X and Y axis.  Change
#define X_MIN_PIN           3
#define X_MAX_PIN           2
to
#define X_MIN_PIN           2
#define X_MAX_PIN           3
and change
#define Y_MIN_PIN          14
#define Y_MAX_PIN          15
to
#define Y_MIN_PIN          15
#define Y_MAX_PIN          14

change
const bool X_ENDSTOPS_INVERTING = false
to
const bool X_ENDSTOPS_INVERTING = true
for each axis.
If a motor is going the wrong direction, change
#define INVERT_X_DIR false
to
#define INVERT_X_DIR true
for that axis.
