  1. So I guess it is a firmware problem because the M106 code exists in the file, as you said. Can anyone provide me with a marlin firmware? Do you know if I can load a different firmware on my printer?
  2. Thank you all for the response but I know about the settings and what to they do and also about the delay until the second layer. I believe it is a software problem. My printer is Sapphire pro by TwoTrees. I attached a photo of my settings for you to see.
  3. Hello, I’m having the following problem every time I start a print. The cooling fans don’t start automatically. I have to turn them on from the printer’s menu. Is there a bug in cura or in printer’s firmware? I use cura 4.8 and marlin firmware. Thank you.
  4. Where do I find Volumetric Extrusion setting? What gcode flavor should I set?
  5. I increased extrusion but the same thing happens.
  6. thank you for your message. I'm using cura 4.8 and my printer is Twotrees sapphire pro, it's coreXY. I checked hotend and changed nozzle when this problem appeared, about a couple of weeks ago.
  7. Hello, I've been using cura for several months now and my 3d prints suddenly come up really bad, I have tried many things to correct them but nothing has worked yet. I really need your opinions. The problem seems like it is software based because I can print the cube file that came with the printer really beautifully. Thanks in advance.
  8. Unfortunately this is no the problem. It seems that it messes up the top layer before starting printing the top graphics. I don't know if I'm telling it correct. I tried to print it with different layer height and line width but it didn't came up well.
  9. Hello, I came up with the following issue. My top layer is missing. Instead of a layer, I can see the infill that is below that. I'm using cura 4.8 and when I slice, in the preview, I can see the layer, but when I reload the gcode file the top layer is missing in the preview. Is there a bug in cura 4.8 or should I pick different settings? I attach photographs from two prints, what I see in cura after I reload the gcode file and how they came up. Thank you in advance.
  10. OK, I solved the issue by enabling relative extrusion. I didn't know what it was for so I disabled it.
  11. I will attach the profiles. I’m using PLA for now. Thank you for the reply. Not working_sapphire_mod_real_size.3mf Working_sapphire_mod_real_size.3mf
  12. This code came up from cura with the settings I applied. I didn’t change anything manually. My printer is not in the default printers in cura but company says that it supports cura. I will delete M83 and see what happens. Thank you.
  13. Hello all, I'm just getting started in the 3d printing world and I think I'm doing quite well, except for sometimes that when my printer starts printing it makes a strange sound from the extruder and over extrudes and under extrudes fillament. At first it sounded like fillament grinding in the extruder but when I sliced again with different profile settings it worked fine. I haven't still figured out what option messes up the print. I'm comparing working and non-working gcodes to find out where the problem is. My printer is a core xy, Two Trees Sapphire pro and I use Cura 4.7.1 and 4.8 ve
