Thank you for your answer greg Valiant. Could you share your parameters/design? because I can not get it to print holes of 0.03. As for my side, I tried to scale it up and down, and it always stop at 0.4mm of diameter, which is equivalent to 0.1mm2 (my minimum infill area is 0 or 0.001mm2). Nozzle diameter didnt change anything. Also, these holes are only open for the top and bottom layers. For bulk layer, the holes are even more filled. Is it the same for you? and nallath, it seems you are from Ultimaker team : are there deeper parameters that I could acess to correct those filled holes? As it is quite important for me, I am ready to go into the software files. Thank you two again Victor

Well at first I did that. But some issues were rising. So starting with a working set of parameters was a good idea, and then converge toward my parameters. I will try again, but that does explain what is the issue with the current set.

Thank you for the answer. My printer is full custom, so I started with a S5 on cura and changed almost everything. It is true that it is doing better with the default parameters. But still, it is not printing the holes below 360 um which is still too big sometimes. So I changed the parameters one by one to join mines. It happens to be the number of "bottom layers". So either, I say, my whole piece is made of bottom layers (which is not very nice), or I need to find what are the difference between the bottom and the rest. And still, I can not print below 360 um. Any idea?

Hi everybody, I am new on this forum, so please be gentle 😉 I used a custom 3D printer, which goes down to 10 um of resolution. I used Cura to slice my device and obtain a code. Then I re-interpret this gcode for my own software. I like cura as I can make do it everything, with a lot of tunable parameters. But I encounter a problem, or maybe a bug : When it comes to small holes or small structures, cura fills everything. My parameters are set so that the filling is at 100% and coming at the junction of 1 wall (or sometimes, even 0 wall). For 'big holes', cura stop at the limits, as it should. But for smaller, the filling just does not stop, and goes over and continue beyond. I have link an image of the result slicing in preview, my structure in .STL (from fusion360) and the Cura project in .3MF. This structure is just for test, with holes from 840 um to 40 um. Cura stops printing them at 730 um. I don't think that my piece is wrong as there is nothing red in Xray view. I have tried changing many parameters and looking on the forum (title of the most promising post : Cura ignoring small holes). Here are some of them : -turned off union overlaping volumes -set maximum resolution to 0.001 -filter out tiny gaps off -minimum infill area to 0 or 0.001 mm2. Looking forward to hear your advises!
