Geeetech

Hi,

I have levelled my printer A20T following the documentation and video provide by Geeetech on the site.
I have printed the model successfully. But when I like to print some model higher, I have a problem on the first layer and the printing don't continue correctly at quality level spoking.

Then I have take a mode into tinternet to print a Levelling control. See the result into the picture attach.

Can you please help me to solve it?
When I check the levelling using the level check function from the printer, the 4 corner of the Bed are OK. But when I go to the middel of the printer, then paper is block and don't move. The Nozle is totally on the Bed.

The printer is new.

Best regards,

Calà Salvatore

Hi, You can check whether your hot bed itself is flat,
Then check the lower height setting, it is generally recommended to be 80% of the nozzle diameter.

Thanks for the reply.
I have install a btouch to prevent the problem.
Seams the hex file on your site don't work correcly.
Impossible to calibrate.
