Me, I turned off my fan. Because it need to be very sticky and to heal slowly. I thought it that way coz it has fiber material mixed. Same thing printing in carbon fiber filaments. It may need also to adjust the speed, which also helps. You also need to adjust your parameter (3-4), & fill.
It will be try, error and adjust is how I experienced it.

nope... i use Slicer program to setting that.

Please tell me where to buy 26cm diameter zebra plate,Thanks a lot!

Sadly they don't have the 22dia in stock... And the european distributor wants 50% more ?

I knew, because the last two stock that I bought，haha

This is the US website for ordering Zebra plates. They should be able to ship anywhere.

Check all screws on the hub.

G29 Z+0.* <----- get * larger and try again

i try G29 Z+0.25; 0.3; 0.4; 0.5; 0.55 actual and 0.6 to far...

screws check nothing change...

Then check tension of all timing belts and set Accel to 500~1000 from the LCD panel.
Set Z-lift to 0.5mm in your slicer program.

wow my Accel was set to 9000 (default value i supose?) !!... i try a print with Accel 1000 and 500 and i post result later thx charlie, we keep in touch

Accel 1000 on the left and 500 on the right.. 500 it's a little bit better but final result is the same.

do you have other prints? or could you share a screen shot of your slicer settings?

Hello, about news, I launched a file yesterday with new parameter Accel 500 and the progress its good, but there is gap by certain places..It come from tension belts?

Hi lawrence, some screen of mi slicer

Thank you for your efforts

You may try these settings:
1. De-string trigger : 10mm
2. De-string Wipe : 0
3. Fan / Cool Min Layer : 3
4. Flow adjust Flow tweak : 1
5. Z-lift : 0.5mm
6. Temprature : 190

yup Charlie is right, the flow tweak stood out for me, excess filament might be causing the problem

OK I try that see you later thx

Hello, then it resulted is even better than on the previous printing, but it stays gap by place which deforms the object.

How long have you used ATOM 2.0 printer?
The reasons I knew which caused gap between layers are two, PTFE tube or printer tolerant becomes worse.

Maybe you sholud check PTFE tube in the nozzle.

The machine has only some month, I don't use it a lot because I had its problem from the beginning. I also thought that the problem could possibly come from the tube.

My last print yesterday.
After change ptfe tube, it got a smooth head. Before changed, its face is not so good.

ok then i try to change it...but do you have a ptfe tube stock because when you told that i have the feeling it's frequently the cause of the printer problem...?

You may contact ALT design or purchase from eBay or taobao.

It's mine.

Okay I touch the purpose I believe. Thank you very much Charlie. I am going to continue of refined the regulations to take out the best print possible. I shall like trying the beta version 2.7 have you got some recommendation?
