Can't Print. Stuck on Homing Axis

[Desedi]

Hello!
I have similar problem with this thread. http://forum.seemecnc.com/viewtopic.php?f=37&t=7750
After pressing print button, MatterControl will stuck on homing axis, and printer will doing nothing. While LCD will consistently switching between starting screen, and temp screen.
SDcard did not work either (after selected file, printer beep 3 beep)

The print will not start until the nozzle reaches the extruding temperature that you have set. I see in you image that the temp is very low.
Either you extruder is not heating up or your thermister has disconnected.

That's the problem, it won't heat up, and stuck on showing homing axis. There is no problem with heating or thermister because if I press preheat, temp will go up. Even if I preheat, it still shows homing axis.

Mine just started doing the same thing, It keeps resetting the zero on the machine too. I finally had my machine running just the way I wanted and now I'm having nothing but problems since using mattercontrol.

I assume by "press preheat" you mean in matterControl. So you know then that the printer will heat from commands from the USB.
Maybe post the first part of the GCode of the print. Which slicer of matterControl are you using? I think it is a slicer setting issue that somehow has turned off the heater but still has the Gcode to wait for heat setting. So need to look to see if the GCode has a value to set the hot end heater. Maybe wrong extruder number in settings could do that.

Hi Dale, thanks you for helping!
The whole thing happened when I try to print PEEK Fan shroud, everything went well, homing axis, heating up and lowering to extrude the first layer. Then I suddenly need to leave the apartment, so I cancel it using MatterControl. After that, shit just happens.
For the slicer setting, I'm just following the assembly guide and using MatterSlice.
As for GCode, right now i'm still Gcode illiterate, so might need some instruction.

[Dale Eason]

So have you tried the old trick of turning everything off including the computer and then back on? Turning computer off is probably not necessary. Just want to reset Mattercontrol by restarting it and also the printer.

If so then we need to see the GCode file the slicer creates when you press print or Generate. To see that file using matterControl press the "Print Que" heading on the left side of the screen. Down at the bottom you will see an "Options" box. Click on that. Select the "Export to Folder". That should open a dialog that will let you Browse for a folder were to save the file. After selecting the folder matterControl will save the GCode file there. The file name will start with the name of the .stl file you were printing. Use a text editor to copy the first 30 or so lines and post those lines here.

For instance here is the top of one of my files:

; Generated with MatterSlice 1.0
; filamentDiameter = 1.73
; extrusionWidth = 0.5
; firstLayerExtrusionWidth = 0.6
; layerThickness = 0.25
; firstLayerThickness = 0.3
; automatic settings before start_gcode
G21 ; set units to millimeters
M107 ; fan off
T0 ; set the active extruder to 0
; settings from start_gcode
M104 S200
M190 S0
M109 S200
G28
; automatic settings after start_gcode
T0 ; set the active extruder to 0
G90 ; use absolute coordinates
G92 E0 ; reset the expected extruder position
M82 ; use absolute distance for extrusion
; Layer count: 20
; LAYER:0
M107
Once we see those lines we can see if the hot end is being commanded to turn on. If it is then there is some problem I don't understand.

Sigh...Gcode are pretty much the same.
I tried to redo the software setup, including clearing EEProm, but still acting the same.
I tried using slic3er Gcode, and print Gcode, still not working (printer keep hitting end stop, and LCD keep switching from temperature screen to Intro screen).
Using SDcard result in three beep, then printer hit end stop, quickly switch to intro screen and back. Not working.

But can you print blinky from the sdcard?

Have you tried to reload the firmware?

Ok, so what does the temperatures show (NOZ: and Target:, BED: and Target:)?

On mine it is possible to turn the LCD knob and display that screen while the printer has hommed and is waiting for temps to reach target.

Hmm, I just realized that you said "switching from temperature screen to Intro screen" mine does not do that and I'm not sure what you mean by Intro screen. If you mean the screen with three lines with the first line being "Repetier Host xxxx" that happens whenever the machine is reset. If that is the screen then your machine is constantly being reset. This could indicate a power supply problem I think. Why it only happens when a print starts I don't know.

Yes, printer keep resetting when starts print, I think its best way to describe it.

When using repetier software to print, it immediate shows job kill (or something like that, I not at home right now)

If you mean doing eeprom_clear and upload repetier-firmware agin, then yes i did.

Ah, well then that explains a lot. Now just have to figure out why the resets happen. I don't have enough experience in that part. But it may be related to wiring from the power supply or the power supply itself. If yours was new this year I think they don't have power supply issues.

A test I can think of is don't put any filament in and then use PLA settings that don't have the Bed heat turned on. Try very low hot end setting if possible. Since the Bed heat is not on then it will require less power. Try that and if you don't get resets then it is not getting enough power either because of wiring issue or because the supply is bad. Maybe other posters will have better diagnostics.

Is the reset flap on the acrylic cover bent into contact with the reset on the LCD?

[Desedi]

Thanks Dale!
Apparently the only problem is my soldering skill
The connection on heating was bad, so it's not working. I guess connection loose when I move the printer.
After some fix, everything is back to normal(axis calibration nightmare).

Great job in figuring it out!

You did not solder the heater cartridges did you?

That is a bit of a no no, as at those temperatures the solder will melt.
