For PLA you don't need a raft, that is used for high temperature materials that shrink considerably. 220 °C for PLA is also on the high side unless you print fast, print without raft at 200 °C and see what happens. If this works we can answer the question.

@0scar: It looks like OP's underlying problem is not that they have a raft but significant extrusion problems. Raft may have been an attempt to solve the failed bed adhesion that resulted from extrusion not working right

When you use "thread", do you mean extrusion width?

@R..GitHubSTOPHELPINGICE Indeed, and without the raft it is easier to see what the problems are.

if you found the problem, please paste it as an answer to this question and draw the followup to a new question. Defective boards happen occasionally - if this is a new printer, write to your seller that the board seems defective and you would like replacement. Otherwise, a boardswap is *relatively* easy.

I am finally unable to reach adequate printing with my Creality 3D. This is how it prints a raft

[![enter image description here](https://i.sstatic.net/WCpw2.jpg)](https://i.sstatic.net/WCpw2.jpg)

As you see, thread is non-uniform.

What can be a reason?

Printing setup:

1. Nozzle is brass, 0.4 width, new from Amazon
2. Filament is PLA
3. Nozzle temperature is 220, bed temperature is 60.
4. I am using autolevelling with BLTouch

I found a problem: it is with extruder motor driver.

I tried to control the extruder with the knob and saw it that rotates with strange sounds and jerkily. Then I connect extruder cable to the socket of Z-axis on motherboard and also tried to control it with the knob. This time I found it rotates smoothly.

I.e. motor is good, cable is good, motherboard 4th driver is not good.
