  1. thank you @VT3D for your reply sharing your settings. resting position, the place where nozzle switch hapens. Is there any especific XY coordinates? or just in the middle of the part
  2. thank you @VT3D for sharing your experiences with us ("dualers"). Could you share some of your settings? Retraction values? Temperatures start/end/standby? speeds? resting position? thank you in advance.
  3. Hi @FalmouthLouis and thank you for keeping this thread. I keep the PVA spool in a plastic box with silica balls, and when I need this material I leave it for 24-48 h in the fruit dehydrator, and then I print PVA from there. Conditions: 55ºC. 40-45% moisture. (it can't be better. I live in a rainy place). These are the parameters in probe, not in the dehydrator knob. Also a member with relevant experience in dual extrusion is @amagro, participating in several related threads. @FalmouthLouis could you please share the settings you are using, I'm ta
  4. thank you for your quick reply @bagel-orb, I think what you're saying is what I'm using... I use to use the support configuration depending on the geometry of the model. Having a look at @FalmouthLouis handle picture, it is the same for me, when I show a 3d printed part to a "3d printing foreigner" the part is always compare with injection moulding, and even I explain it is different approach, that should be one of our goals to spread and normalize the technology. That is why I think dual extrusion should be a battle horse to push the spreading.
  5. thank you @bagel-orb for your reply, and thank you @FalmouthLouis for sharing your experiences. sorry @bagel-orb, but I don't understand what option you are talking about, I have really problems to print with PVA and there is not many information on the internet. You can find some tutorials in youtube but all of them are "wonderful", even the 3d printing nerd has a video but the part breaks when removing the support material, and it wasn't a small feature of the part, it was the main body. I think it was a layer adhesion problem, during a tool change (he says it was a
  6. following. PVA is the biggest challenge for me, and if the 3D printing community really desires the "spreading" of the technology, should ease this matter, as an critical point. My biggest step in this point was when I started drying the PVA. I'm using a fruit dehydrator, before printing and also during printing. Another improvement, due to the using of PVA generates so many problems, i only use PVA as a "Support interface" (2-3 layers). This also reduces the impact in the cost. An to reduce the problem of clogging: Big retraction (direct extruder) but slow: 8 mm; 15 mm/s
  7. thank you @ghostkeeper for your answer. is there any reason why it is not possible to decide the position similar to Prime Tower?
  8. hi all, I know this is a solved issued, covered by @ghostkeeper @amagro and @smartavionics in these threads: #3451 #4511 and #4901 but it is something very difficult for me to set the parametters. The resting position of the printing head must be changed using the .def.json file. (it is not a basic level profile user). I am asking, is not possible to set up this XY position in the profile, or as a override parametters. (similar to Prime tower XY position). Thank you.
  9. thank you for your quick reply @orlin278, Simple, clear and quick.
  10. hi all, Cura 4.3.0. Is it possible to custom the shell number using Per Model Settings or another setting? Do you know how? Please see attached picture, 3 for Wall line count is fine in external perimeter (green), but I'd like it to be increased in the internal hole (blue). Thank you for your reply.
  11. hi @ahoeben, it worked fine. Much better, I don't need to modify the gcode everytime now. thank you.
  12. hi all, Cura 4.3.0. I'm using post processing script to show the layer number and file name, as I find it very useful. The problem (maybe improvable matter) I see is the full word "Layer " on the screen is useless, I'd only need the "L" following the number. For example: "L234"; instead of "Layer 234". In regards of the temperature, for example, there is only the thermometer icon (1 place of the screen). What I'm currently doing to remove the (L)"ayer" letters is using the Find and Replace tool of notepad, modifying the gcode file.
  13. hi all, need some help, please. Quick question. When I'm using Raft, what is the parameter setting the first layer speed of the model? (I see "Initial layer print speed" but it refers to adhesion to build plate). Thank you.
  14. hi all, Cura 4.1. thank you for you help. Could you please tell me what is the meaning of these 2 commands: G1 X92.279 Y152.078 E995.42153 G1 X92.774 Y151.474 E995.46088 G1 X93.378 Y150.979 E995.50023 G1 F1200 E979.50023 G1 F17987547480000 Z2.46 G92 E0 T0 G92 E0 M105 M109 S190 M104 T1 S0 G1 F1500 E-3 ;MESH:omega_larga_c-guia.stl G0 F1500 X92.978 Y161.879 Z2.46 G1 F17987547480000 Z1.46 G0 F1500 X92.978 Y150.46 G0 X92.978 Y149.175 G0 X282.017 Y147.83 G0 X282.087 Y147.76 thank you all.
