  1. It's been a few months now since I moved on to PrusaSlicer as there seem to be no progress in sorting this out.

    Tried a new version of Cura today with the same result as before - freezes and becomes unresponsive within a minute.

     

    Certainly not an issue of multiple displays. But even if it was, I wouldn't count the need to disconnect your other monitor(s) as a solution.

    Shame.

    'Wipe Inactive Nozzle on Prime Tower'

    That is weird. If Cura can correctly position nozzles for dual printing why would it not position it for wiping ? As long as Marlin is aware of the offsets that should work. Sounds like a bug in Cura?

    "nozzle_offsetting_for_disallowed_areas": false,

     

     Well, in fact there is a small strip of around 4mm on the far right that my primary nozzle can't reach. If this is the only way I guess the only solution is to try and avoid it while placing a model.

  3. Thanks, I never set my offsets in Marlin thinking it will be easer to make small adjustments in Cura rather than re-compiling the firmware. Now that I have finally settled on the offsets I'll transfer them.

    I'm pretty sure it always does it over the prime tower when it's enabled.

    Unfortunately no. It hangs over the print

  4. Yet another question

    In my case 2 nozzles are 25mm apart and both can reach every point of the bed.

    If I specify Nozzle 1 offset as 0 and nozzle 2 at -25mm Cura shows 25mm of left side for 1 and 25mm on the right for 2 as unreachable.

    What is nozzle offset supposed to be relative to ?

    • "Heat Up Speed"
    • "Cool Down Speed"
    • "Minimal Time Standby Temperature"
    • "Initial Printing Temperature"
    • "Final Printing Temperature"
    • "Extrusion Cool Down Speed Modifier"

    Thanks you. I am currently on Cura 4.7.1 

    I wasn't able to find Heat up and Cool down speed settings. Will try and play with the others.

     

    On a separate note, can you please explain what is meant by "bridge wall" and "bridge skin" ?

    And if there a setting allowing to make sure bridges are printed across the shortest distance? I have attached a model I am trying to slice, you'll see what I mean.

     

    dual fan duct.stl

  6. It's a custom coreXY machine, Hypercube style

     

    You mean "Extruder Start/End G-code" ? I wonder how to do this efficiently enough. If I add some code to move extruders away from the model while heating between tool change, it will make printing time quite a bit longer.

     

    Ideally I'd like inactive extruder to reach printing T right in time, while the other head is printing.

    It seems like Cura is actually trying something of that sort but very poorly. While printing I see some strange target T for inactive head, not defined anywhere in settings. For example standby T 200, printing T 240, octoprint shows target 215.

    But the result is always the same, extruder will stop about 5mm over the model for anywhere between 5 to 30 second, oozing and melting everything.

     

  7. Hello. I have been using Cura for over 3 years now but for the first time I now have a dual extruder system. What a disaster...

    1. When other extruder is waiting to heat to printing temperature both heads are hovering over the print oozing on it and melting it

    2. If I set "Standby temperature" = "Printing temperature" there is still some delay while both heads are sitting still over the print melting it but more importantly after 2-3 layers my printer halts with "Heater error" message.

     

    I have carefully reviewed all Cura setting having anything to do with dual head printing but failed to find one allowing to move heads away from the model while heating.

    Neither was I able to find out why keeping both heads at printing T results in error.

     

    Any ideas?
