I am looking for away to assign different z offsets or starting layer heights, to each nozzle / toolhead. I am using an IDEX printer and this feature would be very useful when doing two material prints like PETG and PLA. PETG does not like to be squished on the first layer nut PLA does. THis could also be very useful to fine tune the height two different heads. Presently both of these items are available for the to extruders but they a linked together so you cannot change one without changing the other. THank you Bernie

I have been using Cura for awhile and I like many of its features and add-ons. However, when doing manual support placement, the background image of the printer bed, becomes a pain. It would be great if the image could be toggled on or off as needed. This way manual supports could be placed easily on the underside of the model without the bed image graying out the model. Thank you

Is there away to add custom supports for internal features inside a model? I have a box , that is to be printed in one piece, that needs supports inside for the last mechanism only. If I use autosupports the whole inside gets unnecessary supports and not just the latch. The two problem is using the existing tools, but being able to move the camera inside the box model to add a support where I need it. Any help or ideas would be appreciated. Thank you Bernie

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

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

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?

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.

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 tower location it is red, signifying and error, but only if it's visible. Cura should warn users and prevent slicing if the print head goes to the beyond the safe travel area as setup in the machine settings. This way user's know there is a problem and what is the cause. Thank you Bernie

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.

Here you go. I tried to remove the old cura folders but that did not seem to help. Thank you Bernie cura.log

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.

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?

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

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

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 use it? If not, do I need to do a custom support in something like meshmixer? Thank you

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. Thank you

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

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 solution? The tool change does nothing more than move the head to the X30 Y30 position, off the print, and waits until the nozzles change to the correct temperature. Thank you I am still having this problem. The attached file is a test I did today with dual extruders and support material. The second extruder is just doing the support interface layer. From what I can tell ( I am a novice) there is a random move on layer 3 that sends the head back to the X0 Y0 position. This caused a head crash. This position is far away from the print and takes place after the brim has been printed. I see no reason for this to happen. I would appreciate some feedback. PLEASE

I am trying to make a 2 color nameplate with the bottom base one color and the test another color. When I bring the models into Cura they both are placed on the bed. I need the test to be just slightly inserted into the base. If the base is 2mm thck then I would like to test to be inserted into the base by 0.2mm so that the rest of the test is placed above the base ( approx 1.4 mm). This outside text would be a different color than the base. I cannot get thsi to work correctly. I am using Cura 3.41 Thank you

I have recently added a chimera hotend to my reprap printer. I have been using Cure 3.41 on this printer, with a single hotend, for awhile and have been pleased with the results. I the dual nozzle configuration I get duplicate settings for both nozzles, but do not fully understand what I need to change for the second nozzle. I can understand temperature and material but do I need to set things like bed temperature in both extruders? I would be great if someone could advise what settings are shared between extruders, which extruder sets the defaults, and how to ensure that both nozzles are primed for printing. I am alos looking for some help on enabling things like the ooze shiled / prime tower etc. I appreciate any and all support. Thank you

I used the exclusive setting.

CTBeke Thank you very much the slicing tolerance fixed the problem.

Thank you very much for the suggestions. I will try a few of them and see if that resolves my problem. Just a couple of comments. I am trying to understand why Cura does not create the same result as Slic3r and Ideamaker with regards to threads. Purchasing a M6 bolt does not help because I need an adaptor to go the a 1/4" bolt to a m6 thread. Cura has many options and I am sure that once I undersatnd what setting needs to be changed, Cura will be my favorite slicer. But todya I use all 3 three for differnet slicing needs. I will update once I make a few test runs. Thank you for the great support

I have tried to print a few threads that were designed in Fusion 360. The thread size is M6 and 1/4" which is needed to mate a 3D scanner to a tripod. I have printed thread before using Ideamaker and slic3r and both give me a good fitting thread. I would like to use Cura as my regular slicer, but everytime I do threads using Cura they come out too small. Cura is a great program with many options but I am still new to 3D printing and I have not been able to find the best settings to achieve repeatable tolerance. I have printed, on Cura, calibration cubes ( no holes or threads) and they are good. Any suggestions? Thank you
