This is a final update on "3d Stepper Motors NOT Moving, just vibrating?".

I would like to first give a special THANK YOU to all members for your input, it was greatly appreciated.

A SPECIAL THANK YOU TO wardjr (http://www.soliforum.com/user/2291/), grob (http://www.soliforum.com/user/4515/), elmeret (http://www.soliforum.com/user/221/) without your help I would have not made it this far. Your feedback was invaluable, and I am indebted to you three... Thank you a million times over!!! :-)

Update:

1. XYZ Stepper motors - Working perfectly
2. Heated Bed - Working (Bed heats and I can control, but not showing on Viki screen)
3. Ext1 and Ext2 - (Thermocouples working and I can control, but not showing on Viki screen)
4. Ext1 and Ext2 Stepper motor - NOT Working (I cannot get the motors to spin, I have played with configuration files for over 3 weeks, no success YET...) Please reply to this topic here http://www.soliforum.com/post/105276/#p105276

I have posted new topics for all the remaining issues, if you would like to help you can reply on new created help topics.

Thank again to all the members for your help. Have a great day:-)

Thank you for that link... but unfortunately the link is not working, seems to be broken.

But, I will google what you posted, thanks:-)

I am posting pictures of my build so you can have a better idea of what I am currently working on.

This is my first build, I am no expert, so all feedback is appreciated.

3d Printer specifications:

2 Extruders
Heated bed
Azteeg X3 Pro board
Viki LCD Screen
20T GT2 pulleys
X Motor (http://www.kysanelectronics.com/Product … ordID=8319)
YZ Motor (http://www.kysanelectronics.com/Product … ordID=7850)
12Volt 25Amp power supply

I still have a lot more work ahead of me, but for now I just want begin my first print.

If anyone has a similar setup, I am interested in your configuration files.

Thank you for all your feedback.

In response to your question;

EMC2 Robo:
I have not calculated precisely, this was just an estimate. You are correct on the Pulleys (20T GT2 pulleys), and my X motor (http://www.kysanelectronics.com/Product … ordID=8319), YZ motor (http://www.kysanelectronics.com/Product … ordID=7850)

grob:

EMC2 Robo:
z is screw threads

I will play around with the rest and update when I have completed my tests.

Thank you very much "grob" for passing along your knowledge.

In your config dump from the OP:

#define MAX_FEEDRATE_X 200
#define MAX_FEEDRATE_Y 200
#define MAX_FEEDRATE_Z 2

Note Z is 2 (mm/sec I presume - sorry, not familiar with Repetier Firmware!). I would guess this is limiting your z speed?

For steps-per-mm, I'm pretty sure you're not supposed to be 80 for everything -  How have you calculated these? Is this for 20T GT2 pulleys, 200-step motor and 16x microstepping (for which 80 is correct) on every axis?

What are your axes: x/y are belts, z is screw threads (or also belts?).

For belts: steps_per_mm = steps_per_rev * microstepping / pitch / pulley_tooth_count
where:
* steps_per_rev is 200 for a 1.8 degree stepper (most common)
* pitch is in mm: for MXL belt is 2.032mm or for GT2 2.000mm
* microstepping is 16 or 32 normally (depends on the jumper settings for your drivers, and the driver IC!)

For screws: steps_per_mm = steps_per_rev * microstepping / thread_pitch
as above, and where:
* thread_pitch is in mm (typically 0.8mm for M5, 1.0 for M6, 1.25 for M8, 25.4/18 for 5/16" UNC)

For homing, have a play with these:

#define X_HOME_DIR -1
#define Y_HOME_DIR -1
#define Z_HOME_DIR -1

And these:

#define ENDSTOP_PULLUP_X_MIN true
#define ENDSTOP_X_MIN_INVERTING true
#define MIN_HARDWARE_ENDSTOP_X true
#define ENDSTOP_PULLUP_Y_MIN true
#define ENDSTOP_Y_MIN_INVERTING true
#define MIN_HARDWARE_ENDSTOP_Y true
#define ENDSTOP_PULLUP_Z_MIN true
#define ENDSTOP_Z_MIN_INVERTING true
#define MIN_HARDWARE_ENDSTOP_Z true
#define ENDSTOP_PULLUP_X_MAX true
#define ENDSTOP_X_MAX_INVERTING false
#define MAX_HARDWARE_ENDSTOP_X false
#define ENDSTOP_PULLUP_Y_MAX true
#define ENDSTOP_Y_MAX_INVERTING false
#define MAX_HARDWARE_ENDSTOP_Y false
#define ENDSTOP_PULLUP_Z_MAX true
#define ENDSTOP_Z_MAX_INVERTING false
#define MAX_HARDWARE_ENDSTOP_Z false

You want the machine to always home to your endstops, which you have configured currently as MIN for X, Y and Z. The direction I'm not sure but I'd guess was correct. Is it not homing right now?

Ok, so update;

XYZ Stepper motors

All are up and running. I took your advice "grob" "wardjr"and checking wires ensuring they are in the correct pins, I also have my configuration.h file set correctly (not precise, but motors are moving in the direction I want. I also had to fix some stuff in the pins.h file. I have all drivers working on same current (VREF adjusted to around 75% of driver max capacity).

Now I am fine tuning.

Thermocouples still working progress, I will try what "grob" has just posted (thank you "grob")

QUESTION:

Why does my Z motor run significantly slower than my XY motors?

They are set the same: Example of configuration.h:

#define XAXIS_STEPS_PER_MM 80
#define YAXIS_STEPS_PER_MM 80
#define ZAXIS_STEPS_PER_MM 80

How do I set Homing for XYZ motors? How do I save where my XYZ motors go when I home them? Is it in configuration.h, eprom.h, or any other file?

Thank you again and I look forward to your responses... have a great day :-)

(Tim, I don't think he'll need an external amplifier for this one.)

I guess those big yellow connectors etc. are kind of not necessary, and depending on what wire is behind them (looks like a mix of shielded TC cable and regular hookup cable - depending on the relative temperature of the TC amp on the X3pro board and the junction between the normal cable and the TC cable it may add some error) - I'd personally just cut them off and terminate the TC wire directly into the screw terminals on the board, but up to you!

I found this information about configuring them for Marlin, but it tells you the chip they're using and the pins so you might be able to work out how to talk to that with Repetier firmware: http://panucattdevices.freshdesk.com/su … and-x3-pro

This is a thermocouple amplifier:

Thermocouples:

That is correct... I am using K-type thermocouples and running them to a thermistor input.

"elmoret" Why do you think

will not work well?

I appreciate any feedback:-)
