  1. Wish Cura would import models in a saved project file in the same X/Y/Z locations. Just like it does when you open the file as a project. If you just click import models they are scattered randomly on the build plate again and one must adjust their locations all over again. Rick...
  2. Hello all. Is there a better way to determine the Cura Costing "bubble" and which printcore is listed first? It appears to be random when the 2 materials are the same. If there are 2 different materials (PLA and PVA) then it is easy to determine and in those scenarios it appears to list printcore 2 first. I usually determine by the 2 materials and what they are printing by size; however I have a model that the 2 materials are 0.10mm difference and it is impossible to tell which is which. Could adding M1 and M2 something like this: M1: 0.07mm 1g $0.06 M2: 0.17mm 1g $0.12 Or simply ensure the material is listed in the same order with material 1 first and material 2 second? TIA! Cheers! Rick...
  3. Sorry clicked submit too quickly... Also then after the printcore is swapped out then the printcore reheats to then forward material and nothing is present. It then prompts to click 'confirm' when material is being extruded...again wasting time...
  4. Ultimaker 3 firmware...Wishlist item!!! I assume this would be needed in firmware enhancements... Would like to see when unloading or changing a printcore that the print head would not heat to release material when there is no material loaded in the first place. This is a waste of time and a hassle when heating then cooling printcore when it should already know material is not present. TIA! Cheers! Rick...
  5. Hi. Not sure what this is related to but since Cura 3.1 update and firmware on my UM3 the build plate adhesion layer is only applying to 1/2 the model? This didnt happen before and as a result the layer even with glue applied lifts from bed. I've tried more glue on the area w/o the build plate and still no help keeping portion of the model to the bed. Any thoughts on what may be happening here and what to check? I can determine where the build plate will be applied but how to create build plate around entire model base? TIA! Cheers! Rick...
  6. Thanks great video but still hasn't cured my problem that is pretty similar to this initial post. First let me say I've printed around 20 different prints since I received my UM3 2 weeks ago and they all turned out really good. But yesterday while printing a piece the print head is either a) knocking into the print or b) scratching the print and "ripping" it off which then drags the piece around oozing filament into a stringy mess! Also I've watched and stop the print immediately as when the initial "oozing" ball of filament in the from right corner the build plate doe not lower as much as it use to creating a little pyramid and then when that finishes and starts to move the bottom of the fan compartment as it moves away hits the top of the pyramid and sometimes that stick and gets dragged around? I've manually and auto adjust all the time as a precaution but this is not helping my anymore. I even did a factory reset and still the bed in my opion is too close to the nozzle. TIA for any additional help. Cheers! Rick...
  7. Thanks everyone for the info! Much appreciated. Yes aware nylon is very hygroscopic and requires extra special care to ensure it is moisture free. I've seen some spool feeders that do this very thing keeping it dry and dust free while feeding it. Thanks again. Rick...
  8. Hi All. Seen many post on printing with nylon and its exceptional qualities. Before I go down this path can I actually print nylon on my UM3 w/o modifications? There have been a few I've come across that state you simply cannot just print nylon with brass and non-metalic hot ends due to the 240-260c temperature and abrasive nature of nylon will ruin the brass tip? Any suggestions appreciated! Rick...
  9. Hi all. Is there a way to determine with the UM3 how much filament is either a) going to be used in a 3D print or b) after the 3D print is completed? TIA! Rick...
  10. I am very frustrated by this issue as you! I've uninstalled and reinstalled app as well as reset printer and was no help! Please someone at UM respond to this issue!
