I cannot print models
Getting Started & Troubleshooting
Hello every body.
I bought 3d printer JGAURORA A5S from Aliexpress. The printer printed only sample model. I cannot print other models.
I would suggest download
and try printing a
using the default settings.
I'm having the same issue. I do have Cura 4.0.0 and have used the default settings.

When is the print failing? Is it not adhering to the print bed? Is there too much layer shift? I
it isn't adhering make sure the print bed is level along with the horizontal axis. I have used a .2 mm feeler gauge to level the bed and measure the horizontal axis with a digital caliper from the top of the gantry.
If it is layer shift, I have slowed my detailed prints down to make sure the prints don't shift when the print head moves.
The sample that they gave will print fine. When I create a new model the print never starts. The status bar moves like it's printing but it never starts.

I figured this issue out, I was putting the starting and end code in like this:
G28 ; Home all axis
G1 Z15.0 F6000 ; Move up 15mm at 6000mm/min (note: more than the max speed set in the printer firmware)
G92 E0 ; Reset extruder length to zero
G1 X0.0 Y0.0 F1000.0 ; go to edge of print area
G1 Z0.200 F1000.0 ; Go to Start Z position
G1 X60.0 E9.0 F1000.0 ; intro line
G1 X100.0 E21.5 F1000.0 ; intro line
G92 E0.0 ; reset extruder distance position
G91; Set relative positioning mode
G1 E-5 F600; retract filament slightly
M140 S0; Turn off the bed heater
M104 S0; Turn off the nozzle heater
G28 X; Home the X axis
G0 Y280 F600; Bring the bed to the front for easy print removal
M84; Turn off the motors
The machine has an issue with the remarked out statements. For example G28 ; Home all axis. I had to take out the ; and everything in front of it, Tried is and the printer stated to run and has been doing this job for 6 hours so far. .
Scripts look kike this now.
G1 Z15.0 F6000
G1 X0.0 Y0.0 F1000.0
G1 Z0.200 F1000.0
G1 X60.0 E9.0 F1000.0
G1 X100.0 E21.5 F1000.0
G1 E-5 F600
G0 Y280 F600

Thanks for your work, Swittler, but your solution did not help.
I have the same problem on my brand new JGAurora A5S. Only the sample file "YF20 20181101.gcode" will cause the printer to even begin heating up. Any other file simply ticks up the percentage gauge while neither preheating nor moving the nozzle in the slightest.
I have tried three different versions of Cura: 3.6, 4.0, and the 1.15 / JCreate that shipped on the SD card.
I originally tried Marlin gcode flavor, then switched to RepRap since that was what the sample file used, still nothing at all.
I have tried 4 variants of start and end code I found around the Internet, including yours here. I also tried copying the start / end code from the sample file. Still absolutely no response from the printer.
I tried using taking the sample file, and copying-and-pasting move instructions generated by Cura, leaving everything else about it intact. The printer will not move at all.
I am currently formatting the SD card to see if that helps.
Does anyone know how to make this work? I have only owned one other 3D printer, but it always worked perfectly. I have reached the limits of my knowledge.
It is resolved! I posted more details on another thread I started, but I think what did it was formatting the SD card.
Swittler, did you format your SD card before this new start / end code started working?
I was trying to print via USB and was having the same problem. The printer would move but would not extrude. I opened the sample file "YF20 20181101.gcode" and copied from the start of the file to the printer settings start gcode:
G1 Z15.0 F6000 ;Move the platform down 15mm
;Prime the extruder
G1 F200 E10
And to the stop gcode:
;Retract the filament
G1 E-1 F300
G28 X0 Y0
That seemed to kick everything off okay.
I tried all those g-codes and even formatted my SD card to FAT32 but those those don't seem to be working
