Da Vinci 1.0 Azteeg x5 WiFi Build (Page 4 of 13)

I never changed mine from  0 and it worked.

Got my IDC cable in the mail today finally, same deal. Lights come on back light and lights on the knob of the viki but no words on the display... what am I missing. Below it says I need to “uncomment” the config settings what does it mean by that .

Viki2 wires to an Azteeg X5 mini with a flat cable as it has 1:1 pin mapping. The ConfigSample for the Azteeg mini has the config settings required, just uncomment them,

The config for Azteeg X5 is different to smoothieboard and is shown in the file https://github.com/Smoothieware/Smoothi … onfig#L178

Hey I got the display to work! I think I figured out what the issue was.. I had the file named Config.txt I manually was typing config.txt as the file name. I think the end result of that because of the .txt extension made the name config.txt.txt and the board wasn't using the file as a config file because it was named config.txt to the t like you said in your previous post..

Now that the display is working!!!!! What is the next best step for setup! How do I set of Home positions for the extruder, how do I start getting the steppers set up to physically move for the first time and so on.

I was messing around in host trying to move the motors a little at a time, as well as on the viki 2 under jog. It said they were moving but nothing was moving or making noice. Dumb question but I have my end stops not plugged in at all right now. Will this completely disable the motors from working?

Also how do you learn command names is there a list somewhere

yes I put the jumpers in for micro stepping, I’ll have to get the end stops connected I think I have them wired wrong that’s why I unplugged them , if you remember earlier the board wouldn’t even run a few pages back because of the end stops being plugged in. So either I have them wired wrong or

I actually have one of these exact endstops in front of me now. Mine was a bit cheaper as they left the LED off. Physically the endstops are NO. The wires you should be using are the signal wire which is green and the ground wire which is black. The red wire will not be used unless you want the LED on the endstop to light when it is active.

If you are using the harness that came with the endstop then the position of the GND and SIG wires will have to be swapped in the connector that plugs into the X5. On the X5 it is GND SIG V+. On that stock harness that came with the endstop it is SIG GND V+.

So from the Endstop the black wire should be where it is and it should go to the GND pin on the X5. The green wire should be where it is and it should go to the SIG pin of the X5. The if you want the LED to work the red wire should go to the V+ pin on the X5 at the endstop ports.

The board is looking for NO endstops as well. So this configuration is correct. No you may need to make firmware changes depending on homing direction and if the firmware see the endstop as open when open or closed when open as the firmware can invert the signal.

So this area below in the firmware is where the endstops are controlled.

# Endstops
endstops_enable                              true             # the endstop module is enabled by default and can be disabled here
#corexy_homing                               false            # set to true if homing on a hbot or corexy
alpha_min_endstop                            1.24^            # add a ! to invert if endstop is NO connected to ground
#alpha_max_endstop                           1.24^            #
alpha_homing_direction                       home_to_min      # or set to home_to_max and set alpha_max
alpha_min                                    0                # this gets loaded after homing when home_to_min is set
alpha_max                                    200              # this gets loaded after homing when home_to_max is set
beta_min_endstop                             1.26^            #
#beta_max_endstop                            1.26^            #
beta_homing_direction                        home_to_min      #
beta_min                                     0                #
beta_max                                     200              #
gamma_min_endstop                            1.28^            #
#gamma_max_endstop                           1.28^            #
gamma_homing_direction                       home_to_min      #
gamma_min                                    0                #
gamma_max                                    200              #

It gives you notes on the alpha endstop as to what the settings do and what you need to set depending on homing direction and endstop being min or max. In your case they should be MIN. So set as they are should be correct. You will also need to look at the section on controlling motors.

This section below is the relevant section.

# Stepper module pins ( ports, and pin numbers, appending "!" to the number will invert a pin )
alpha_step_pin                               2.1              # Pin for alpha stepper step signal
alpha_dir_pin                                0.11             # Pin for alpha stepper direction
alpha_en_pin                                 0.10            # Pin for alpha enable pin
alpha_current                                0.5              # X stepper motor current
x_axis_max_speed                             30000            # mm/min
alpha_max_rate                               30000.0          # mm/min actuator max speed

beta_step_pin                                2.2              # Pin for beta stepper step signal
beta_dir_pin                                 0.20             # Pin for beta stepper direction
beta_en_pin                                  0.19            # Pin for beta enable
beta_current                                 0.5              # Y stepper motor current
y_axis_max_speed                             30000            # mm/min
beta_max_rate                                30000.0          # mm/min actuator max speed

gamma_step_pin                               2.3              # Pin for gamma stepper step signal
gamma_dir_pin                                0.22             # Pin for gamma stepper direction
gamma_en_pin                                 0.21            # Pin for gamma enable
gamma_current                                0.5              # Z stepper motor current
z_axis_max_speed                             300              # mm/min
gamma_max_rate                               300.0            # mm/min actuator max speed

As you see in the notes adding a ! After the pin number will invert it. So for example if the Alpha motor is running the wrong way you can change the line

From

alpha_dir_pin                                0.11             # Pin for alpha stepper direction

To

alpha_dir_pin                                0.11!             # Pin for alpha stepper direction

This will make that motor run in the other direction. This assumes the motor wiring is correct of course.

Alpha = X
Beta = Y
Gamma = Z

This board can also be used on a Delta/ Kossell style printer and on those they do not use X, Y, and Z axis since all axis move up and down only on those. So they use Alpha, Beta, and Gamma instead.

If you send a move command to a motor and it moves in the wrong direction then you need to add ! to the motor direction pin. If it does not move or sounds strange then your wiring could be wrong.

Keep in mind however for the Z axis up is actually down. The movement is in reference to your extruder, not the build plate. So if the build plate moves down the extruder is actually moving up.

As for my comment, that is in regards to Endstops wired as I specified. If the extruder is not home the switches are open. So when all axis are home all the endstops should be closed and show active. This is where the M119 command comes in as it shows you what the firmware is seeing in the home and not home positions.

You will also need to set the max for each endstop based on the max build dimensions of your printer. There is a post here that details converting a 1.0 to RAMPS like I did and I believe he details those settings for the MAX.

So based on that snippet you posted your Endstop section should look like this.

# Endstops
endstops_enable                              true             # the endstop module is enabled by default and can be disabled here
#corexy_homing                               false            # set to true if homing on a hbot or corexy
alpha_min_endstop                            1.24^            # add a ! to invert if endstop is NO connected to ground
#alpha_max_endstop                           1.24^            #
alpha_homing_direction                       home_to_min      # or set to home_to_max and set alpha_max
alpha_min                                    0                # this gets loaded after homing when home_to_min is set
alpha_max                                    237             # this gets loaded after homing when home_to_max is set
beta_min_endstop                             1.26^            #
#beta_max_endstop                            1.26^            #
beta_homing_direction                        home_to_min      #
beta_min                                     0                #
beta_max                                     217              #
gamma_min_endstop                            1.28^            #
#gamma_max_endstop                           1.28^            #
gamma_homing_direction                       home_to_min      #
gamma_min                                    0                #
gamma_max                                    202              #

As for your other question. There are no writes to this file made by the machine. Everything is entered by you. When the Endstop switch is closed by the presence of the carriage or bed against it's switch the system knows this is the 0 position. What will happen then is when a move is called from the terminal or from g-code the machine will move that axis the requested distance and it will keep track of the distance as it moves back and fourth along each axis. If a call eve request a move beyond the MAX, it will move to the MAX and stop. This called a soft stop since there is no actual switch there.

The homing direction refers to the direction the axis needs to move to be at that endstop. If set to home_to min then it should move towards the zero position for that axis. If it is set for home_to_max it should move towards the 237, 217, or 202 of the respective axis.

for your machine home is Z at top, x at right and y at back. So right back corner for the 1.0. The reason a said use a host such as Pronterface or Repetier that allows you to make moves in 5, 10, 50, or 100 multiples is so you can move a few mm and see what direction is moves when you request each direction to assure proper direction is moved. This also avoids it going off on it's own relying on the endstop to stop it..

Once you assure correct movement and confirm using M119 that when none of the axis are home that it returns inactive for all axis and when you move them all to home by hand and send and M119 it returns all active then and only then can you tell the host to home all and see what happens. Just keep your hand on the power switch or plug in the event it over shoots or your offset for the bed is wrong for the Z height. Once you get movement correct and endstop behavior correct then you can move on to calibrating steps per mm on each axis to make sure when you ask for 20mm you actually get 20mm printed.

Your extruder motor also needs to be checked for correct direction as well. I just for that you will need to heat the machine and actually try to feed filament. That motor too will need to be calibrated for steps per mm. If you use 32 bit microstepping then you cam probably start with the numbers listed in the snippet to get in the ball park.

It will just hit the physical limit and make the motor grind. It will not hurt anything as long as you don't let it sit in that condition for 5 minutes or more. It should also time out on its own after a few but you should never rely on that.

Again that's why during your adjusting and setting stage you only request small moves to confirm travel direction and you use M119 to confirm the endstops are functioning as expected. Don't send a home command till you assure everything is funcioning as expected by small test on all axis and stops.

If it does move passed a stop or soft stop it will sound much worse then what it is actually doing. All that is really happening is that the motors are are reaching their torque limit and releasing and just repeating over and over many times a second. If left in that condition it could over heat a driver but for a few moments it won't hurt anything.

So what that tells us is that a closed switch is seen as open. 0 means open, 1 means closed. The other numbers are the pin numbers for your reference. Go back and add an ! at each of those end stop pins to invert it's operation. On the min endstops line take off the carrot by the pin number and put a ! in it's place. Then reset the board, connect it and M119 should give you the opposite. Right now it thinks all endstops are pressed so a move in the direction of an endstops will be ignored.

Extruders don't get endstops. Just XYZ axis.

The max setting should be commented since you don't have max endstops. If commented it is ignored. When you move all the axis to home with power off, then power up and send M119 what do you get? When all axis not homed what do you get. Don't press a switch, actually but the axis in home position by hand. It's important to make sure the machine is actuating all the switches at home.
