A30: Restart required after each print, or something wrong in the gcode?

[cglightNingART]

Hi,
i have an error with the Geeetech A30 (with auto leveling sensor / Printing from SD-Card / Firmware V1.36.57 / Hardware V3.2).
The first print works very well, but if i try to send a second print behind without switching off the device in between, the A30 does the
Autoleveling, but instead of 3mm filament output and starting printing (the same file) again it comes to very fast constant filament spitting, till i swich it off...
Is this a normal behaviour for the geeetech, or something wrong in the gcode?

the same file with a restart of the printer (no problems)

as well as with Cura 4.0.0 and profile downloaded from the Geeetech homepage (forum)
(why this Bedsize and fixed Temperature in Start-code???)

Hi, I think you may need
1. Check if the filament is bonded，the temperature problem is overheated
2. Is the Cura software damaged? You can find it here.viewtopic.php?f=69&t=61552&p=85784#p85784

Hi, thank you for your answer.

The Filament is not the Problem. It happens with every filament and allways, if i don`t swich off the Geeetech before starting the next print.
It happens with two Versions of Cura. Cura 4.0.0 is fresh installed.

Someone send me a file, which was sliced with slic3r pe. Everything works fine with this file and i also can start a second print without swiching off the printer between.
But in his gcode, there is also a line with G21 for setting the metric.
Maybe i will try it to add this line in Cura as well.

The printer works with Cura with no problems, when i add G21 (to set the metric in mm) in the start code. (Printer is located in Germany )

That is great!
