  1. Is there away to randomize the starting point of new layers in Cura 4.7+? I have been trying to print a small part with delicate overhangs using Peth. The part prints well except the overhang seems to be at the start / endpoint of the layers and as such the hotend stays on it too long melting it is there away to start at another point so this area can have a chance to cool? I am printing slow, have tried the fan on low speed, and used z hop. They help alittle. Thank you
  2. I am trying to add a placeholder for my dual extruder printer in the start guide without success. I want my unused nozzle, only printing with one nozzle, to preheat to 190. I have tried using the tag for material_print_temperatre,0. It works but I have no idea where it's getting the temperature from as it does not appear to be any that is shown in the active profile. Is there a list of placeholders for version 4.6? Thank you Bernie
  3. I have a duel extruder printer and I sometime print with only one extruder. In order to reduce dragging, on my print, I set the unused nozzle to a temperature around 175 for PLA. I set this in the material profile for the unused nozzle. However Cura does not heat this extruder at all because nothing in the model uses it. Shouldn't the standby temperature be used as the default regardless of of the nozzle printing or not?
  4. I am using 4.4.1 and there seems to be a big in the brim on outside only feature. Even with it enabled the brim is being printed on the inside and outside of my model.
  5. I have noticed a continuing problem with Cura with regards to third party dual extruder printers. I f you use your printer without enabling the prime tower or ooze shield everything works fine, i.e. no crashes. If you enable the prime tower or ooze shield, and don't look at the prime tower location, it could be defaulted off the print bed. This results in a crash. Cura does not earn you that the tower is out of bounds and slices the print without warnings. This happens with either the prime tower or ooze shield enabled. If you expose the prime to
  6. Those profile was added by the manufacturer. It works fine inversion 3, and does work in version 4 once you select a new printer and get past the wizard.
  7. Here you go. I tried to remove the old cura folders but that did not seem to help. Thank you Bernie cura.log
  8. I have been using version 4.3 and have imported my configurations from previous versions. Most of the time when I start my computer and open Cura I am prompted by the initial screens and license. I am then walked through the printer selection wizard. The wizard does not show my profiled printers, but asks for new ones to be added. Once I add a new printer Cura takes me to the main screen where I can select all of my already installed printers and profiles.
  9. I think I understand what you are suggesting but how will this allow me to use the PVA only for the interface layers? From what I can see this will allow me to make all of the support structure out of PVA or the main material. Is it not the slicer that determines which support layers are to be printed with which material?
  10. Doing in CAD is possible but then I can not choose a separate material for the support interface layers, i.e. PVA. I have a dual extruder system. Maybe it is something the developers could add in the future. Thank you
  11. I would like a method to provide supports for tall thin objects, like long bolts, where a support structure could be provided along side the model. The supports should be customizable in size and with branches connecting, to the model, a defined intervals. This would look similar to a support tower used on rocket launch pad to support the rocket. Thank you
  12. I have been trying to print some very tall thin models ( 10mm wide, 229mm long and 190mm tall). I have had little sucess with this. I have tried large brims, reduced speed, blue tape, glue stick etc. All f which have failed near the top of these 11+ hour prints. I am looking for away to add a custom support along the sides of the model to provide stability as the model grows taller. Maybe a removable support that angles from the bottom up to the top. I do not seen anyway to add a custom support like this to Cura. Does this feature exist in Cura 3.5 and if so how do I u
  13. I have a reprap 3d printer using marlin 1.14 and a chimera hotend. I am using Cura 3.5 and having good sucess with 2 color prints. I use a prime tower and a 15 degree standby temperature on may nozzles. When the nozzles are swapping the hotend moves to the edge of the print and stays there until the temperatures reach the new values. Is the distance that Cura uses for where to move off the print related to the nozzle offsets and if so what is the relationship? I am currently having my x and y offset set to 0, leaving marlin to handle the 18.2mm offset.
  14. Yes I know I can just change filaments, but since I have two extruders and nozzles it would be better if the printer can do everyhting without me being there. An even better thought than inserting one stl into the other, since this means both nozzles are printing the interior overlapping layers, is to have a nozzle switch command at a given layer height. I have not found a way to do this in Cura without directly editing the gcode. Thank you
  15. I have been using cura 3.4.1 for my dual extruder reprap machine and have been using the change tool gcode for moving the nozzles off the print why they heat up. The print works fine, but then randomly, I will get a move that sends the print head crashing into either the X or Y or both endstops. This random crashes did not occur prior to the use of the tool change code and there are many tool changes thoughout the print. But somewhere during the print, could be hours into it, the heads will crash. Has anyone else experienced this and if so can you supply a s
