Hello,

I have try to print a tower temp with a new filament. But my printer doesn't print.
Attached is a photo of a temperature tower that is not printed.
The nozzle is new and the ptfe change not long ago.
Anyone know where my problem is coming from?

Thanks

Hi, level the hotbed before printing,
PLA consumable printing temperature is generally around 210,
The extruder can then be calibrated.

Hi, you can refer to this:https://mattshub.com/blog/2017/04/19/ex ... alibration

Thank you,

Do I have to do step per mm? In the geeetech a30 there is bondtech or similar extruder?

Hi, you can first, level the hot bed.
The distance between the nozzle and the hot bed is the distance of a piece of leveling paper,
then calibrate the extruder.

I forgot to tell you that I am currently printing with the cold tray.
Because I have an error when I heat my tray :
Error : nozzle 0-temp the heating element is out of order! Please kill the job manually.

Hi,you need to check whether the thermistor wiring at the hot end is fully connected or loose,
If not, you need to measure the thermistor,
Make sure that the hot end is normal for normal printing.

Where is thermistor?
