Having an issue with my new Geeetech D200 and still a bit of a

Having an issue with my new Geeetech D200 and still a bit of a newbie too. Whatever I print it seems the last lines printed at the top are not very neat and clean and the bottom seems to be too thin. The rest of the print seems fine for the most part. I’ve leveled the bed, tried different materials, using Cura 3.4 currently. My older printer prints it fine. I’ll attach pictures of the latest example. But this has happened on almost all prints. And fine details on the sides/front/back all seem great on other prints. Thanks for your thoughts.

the temperature looks to hi for the material.

I’d try increasing your first layer height a tad.
For the other issue:
Does the filament print well on other printers? Did you do a proper extruder calibration, followed by a temp tower and a multiplier calibration?

Thanks for these responses so far. I’m using PETG at 232 degrees based on the manufacturer’s recommendation of 230-250. Regarding the first layer height, I will try that. Yes, this same spool prints well on my other printerand at the same temperature. On the last part, I will admit that after having only been 3D printing for the last 3 months, I’m not sure where and how to address those things you mentioned. I do

… have the extruder nozzle set to. 4mm

Comparing 2 printers results, even if they’re more or less the same is the wrong approach, this doesnt work.
Google for mattshub extruder calibration. With this manual you can calibrate your extruder and you multiplier setting.
Search for a temp tower on thingiverse and lower the temp by 5C for every stage of the tower (like from 240C down to 190C). After printing this, decide sich temp worked best

Ah, I understand. Will definitely try that. Any other ideas welcome. Thanks.

I was gonna guess over or under extrusion

Thanks as well Chris.

This actually looks like SEVERE overextrusion to me, possibly some mismatched filament diameter, nozzle diameter, or all of the above. You need to tune your extruder properly. Additionally, 230C on Machine A isn’t typically going to be 230C on Machine B. These thermistors are generally rated for 5%/10% difference @ something like 150C. …but we’re actually going above many of their specifications by running them in the 200C-300C range. So expect anything with regards to temperature.

That corner peeling up is probably due to the bed not being level (if you don’t have any kind of auto bed mapping hardware)

Thanks. I’ll download that extruder calibration information above and try to learn how to do that!

I would not count on thermistor readings being at the same temperature even if the readings are being compared to the right table. It might say 220-230 when it is actually 223-233. That is especially a possibility when you have to replace the thermistor.

Did the one corner lift?

Thanks Nathaniel. Good point. Regarding the corner, I don’t believe that it did a it repeated on a second try. But I’ll check that on the next try after I get to try that calibration. Thanks!
