Like someone commented, looks like you’re printing too hot. Please post your config.g and response to M115, so we can see your thermistor settings, board type and firmware version.

Can't see too well on my phone but potentially under extrusion. The inner contours on the holes look like they are under too much twnsion as extruded and being pulled out of position.
Calibrated e-steps? If running much over checked to see of you need Linear/Non linear extrusion correction?
However, you should be sure you are happy witj extruder temp as @droftarts suggests first, as you need to redo the non-linear correction for differwnt temps.

the print setting was at 60mm/s, 245 degrees hotend and 80 degrees bed heating
the printer has a 60w ceramic cartridge (i had some issue of temperature stability before tuning hotend heating because it became hot too fast and it exceed the 15 degree over temp during warming, now seem to be fixed)
pt100 platinum temperature sensor
200w 230v heatbed
at the moment i feedback two errors about temp at the startup after autotune of heatbed and extruder
Warning: Heater 0 appears to be over-powered. if left on at full power, its temperature is predicted to reach 320C
Warning: Heater 1 appears to be over-powered. if left on at full power, its temperature is predicted to reach 1326C -

unrelated but unless there is a very specific reason, you are better off at x16 with interpolation.
the print setting was at 60mm/s, 245 degrees hotend and 80 degrees bed heating
what material are you printing?
i had similar problems like that with amazon petg, and after switching to a different petg the problems where gone.

M350 X32 Y32 Z32 I0 ; configure microstepping with interpolation (I1 = on, I0=off)on my older hadmade 3d printer i had problem with interpolation at 256microstepping, causing similar problem like ones that i have here (but on marlin firmware) so i'm triying to understand if it was an firmware problems or not, using standard 32 microstep without interpolation, and interpolate only motor, tried also to interpolate all/interpolate no ones, motors at 16, 32 microstepping
nothing changed at alli'm printing with 3d jake niceabs
specs said 240/260 degrees extruder
80 degrees bedi'm just printed a couple of kiloes with this settings without problems at all, so i suppose could be the same on reprap firmware (first board with it for me)

did you have a pt100 on the other printer as well?
due to the nature of the thermistors temperature on one printer is not equal to another.
pt100 and pt1000 beeing the exception here. -
@Eclipssato Your picture looks a lot like some prints I once had with a bad batch of PET-G. Have you kept that PET-G dry? (Although in my case the filament was fresh out the sealed package so must have been subjected to moisture before it was packed and sealed).
Try printing with some other filament - preferably something that isn't hygroscopic - e.g. PLA and see if that makes any difference.

its abs in my case, and yes, i've dryed it. i'm also sure of the quality of the material because ive printed later with the same spool on another printer for test. no isuue...

sorry for the stupid question but.... 245 degree should not bee the same on every thermistors?
i would like to understand why there's could be some difference between thermistors at the same temperature.
if you consider that basically this printer it's made for printing peek and ultem, so thermistors will be really noticeable parts of the system, i have to learn about it

@Eclipssato said in Strange textured print:

unfortunatly not.
for example B3950 thermistors are defined as
B25/50=3950KMeaning for the range of 25C to 50C the beta value is 3950. it does not specify the beta above this and it can vary widely.
-
@Veti
ok, it make sense. thankyou
now. i'm looking to the duet3d daughterboard pt100 and i see that with 100ohm resistance the displayed temperature should be 0 degree (exactly as the pt100 specs.)i've tested my pt100 at 0 degrees on ice and it release me 100 ohm , so it should be like factory specification.
adding an 100 ohm resistance on the daughterboard i read -3.2 degree.
it should be acceptable or i've have an defected board?
i'm really not sure that this "3 degree less" could make me really difference during the print, specially if we suppose i'm printing too hotEDIT: checked now. it's -3.9 on both channels
-
as i said above pt100 and pt1000 should normaly be very accurate. the problem most of the time are other thermistors.
the easiest solution is to print a temperature tower and find the correct temperature to print for that printer.

i agree with you. looking fowards your suggestion i'm performing an temperature tower test, using simplify 3d , and not cura, at the moments seems that the texture problems are gone, even printing at 260 degrees.
sound strange, i will post a pic when print finish.i wont believe that 3 weeks of issue was generate only from the gcode files of cura

As you can see seems that the issue was caused from some bad gcode writing from cura, exactly same print configuration in simplify3d works nice.
Test has been performer with 9 different temperature every 50 layer at 0.2 mm, and I think that work flawlessly at almost every temperature (some adjustments needed maybe, but nothing about temperature and extrusion) what do you think about it? How can I improve it more?
direct suggestion and critics are appreciated!
