Hi all, I have finally decided to try the orca slicer mainly due to the calibration tests and prints on offer after suffering from numerous issues.
I have carried out the Temp Tower, Flow Rate test and the Pressure advance but found the pressure advance actually made prints worse so I removed that and left it in auto. After doing the other two I tried doing the Orca-Add Primative-Autoddesk FDM Test and would like to attach the photos for advice and comments but can’t see how this is done??. All input welcomed. Thx
You drag your pictures from the desktop and drop them in this REPLY window and they upload and attach automatically. Or you could click the “Picture” button here:
Or you can use Screen Grab to grab an image and then hit PASTE to put it in this window, which is how I did that image above.

Thanks mate, I have now updated my original post. I never found that toolbar you screen grabbed but the drag and drop worked fine. 
You don’t say what the filament is. But it’s kind of stringy so I’m going to guess PETG. It’s also oozy so I’m going to ask, how long and at what temperature did you dry this filament before attempting the print?

hi mate, sorry I did not realise I had forgotten to mention the type of filament, it was in fact eSun PLA+. I had not dried it as never had to before but will give that a go anyway. on all the other calibration and trial prints I never saw any signs of the stringing either!!
i am using esun PLA+ X1C printer. And have a very good results on my Prusa mK3s+ no enclosure, but filament always in dry box. In the X1C pretty average to bad results initially similar to yours if not worse. Finally got a good quality but don’t bother any more as my AMS is loaded with esun eASA, esun ABS+, and esun PETG , and HIPS
Never had issues with ASA , or ABS+
Only using Orca slicer better results
to get to a good quality:
- dried the filament - comes wet usually from the box
- Pressure advance and flow calibration - temperature only once realized that does not change a lot with in ± 10C from the initial temperature
- Part fan speed 100% always
** Chamber fan always on 70%-80% 100% too noisy but better** custom gcode required in the filament , some time keep the door open a bit on top of that
Started the Aux fan as well between 40% and 70% current setting 70% - after realized that is too hot inside for PLA , re-did the calibrations again with door open and dried filament and already had a base print temperatures and fan speeds set
- print at 215C
- Some times reducing the print speed for even better results bellow 150mm/S and usually keep it under 200mm/S
But as i said don’t use PLA+ any more on X1C or rarely only, and now only on the Prusa
Bare in mind that the torcher test above 30% ( 20 and , 15 ) is almost impossible to make it perfect , but the rest should be much better
I am thinking to try different PLA as the Bambu PLA was much nice results out of the box
Also eSun PETG gave me some grieves with oozing and dimensions, now acceptable , but keen to try different brand
Thanks for the info Vladimir, I have just redone a temp tower and based on the results I would agree with the 215 you use. I would like to use ASA as well but I have health issues and worry that the fumes would be detrimental and I am unable to vent to the outside!!! Will keep testing
yes esun eASA and esun ABS+ can have harm i printed a few 1kg roles with out ventilation and was getting dyzzy , until i read that is safe with ventilation , which i installed after my first vomit. Also did not realize that the carbon filter does not work as the chamber fan needs to be off through the print, and added some code at low speed after the print finishes
here is my pressure settings for eSun PLA+ but it might be off as i have been changing it on the fly some times with out recalibrating and with color and object changes. You kind learn from the print what needs tuning after some time with out any calibration prints
The PA looks similar to what I was getting after my calibrations (in fact I got 0.28) but the flow ratio I use after calibration is 1.018 but that is with eSun PLA+. I also found that I had to disable my PA input value as it made the prints worse!!! I will wait on the smelly filaments until I get some sort of extractor in place!!! Thanks again.
oh, I just attached the latest temp tower and you can see 220-225 looks to be the best!
Great looking good. I need to test the white color , flow 1.018 looks high to me for eSun PLA+ , my one 0.975 and 0.025 is on Green and Orange,
note that the Print nozzle temp , flow and K are interrelated
But once good flow and K are set */- 5C does not affect so much , But i usually repeat the flow and K
If you unticked the Pressure advance and have not used the Auto flow , then will use K=0.02
Thanks Vladimir, I will continue with my checks on all my eSun PLA(+) filaments. just for interest I will re-do the flow rate test and post the results on here. Cheers
Hi Vladimir
I did the Pressure Advance calibration in Orca again using a different model output this time, after the recent update to Orca.
For me 0.03 looks to be the better result, what do you think?
For some reason it would not let me select eSun PLA+ so I had to use Generic PLA Black!!! May have to unload and reload the AMS!!
Very difficult to see from this model and photo, probably somewhere between 0.03 to 0.04. i use the vertical one(tower) and caliper or ruler and measuring on a few sides and average the results . Much easier to see. my son and me are playing with TPU and TPE at the moment , now that is some mission…
I will try the tower version next but at the moment I am stripping the AMS due to broken filament !!! I did it for the first time this morning and foolishly only checked the route for the suspect one which actually had filament in it. Put it all back together and had the same problem on another reel location. Just stripping it down again but will check them all this time LoL. Good luck with the TPU, I loved that stuff on my Prusa but have not tried it on the X1C.
