A-20 prints using Cura - printing like swiss cheese

[Kurtis]

Greetings to all. Been using an Ender3 Pro for the last few months and just got the A-20 up and running and attempting first print.

I tried the easyprint software for windows with the A20 and got a rough mottled finish on the part. I am more familiar with Cura so I tried the cura instructions here http://www.geeetech.com/forum/viewtopic ... ura#p90212 and loaded up my part and used the same file I printed using the Ender to compare the prints but got the same rough flimsy print results. I printed at 100 % infill but the part is soft and rubbery. It should be laying down nice flat lines.

I spent the day and used every trick I know from using the Ender everyday for the last few months. I tried different heat settings from 200 to 205, tried different filaments, changed out the nozzle just in case. As I am new to A20 I dont know if it is the print head, the firmware or the software settings.

Below is a comparison of the Ender print on the left and the A20 on the right. I have seen lots of great prints on the net and in the forum here so wondering if someone can help. TIA

You should look at the extruder topic. There are many posts for a not working extruder.
I think you heard "clack, clack, clack" from your extruder.
