wish list - ability to prime a pre-loaded filament

[daj1u06 0]

Hi, it would (for me at least) be really useful to have a prime printcore option in the ultimaker's menu system. Just to be able to heat a selected printcore to clean it from the last run and check that the filament is flowing well, without having to load, remove, replace and reload it. Especially useful with prints with PVA support as the printhead gets pretty messy and spattered. Thanks.

Well I am not sure how easy it is to do this these days on the new Ultimaker printers but I have used Repetier-Host for over 5 years on my non Ultimaker  to control my prints and to do all those things for me, including changing flow speed or print speed mid print. I know Ultimaker users have used it I the past, just have not seen the subject posted for a while.

@daj1u06 You can easily do that manually from the printer's menu, not from CURA.

 

You can select a printcore, heat it up, and manually move filament to prime it and check the flow.

Yes but I then have to go and look up the required temp, which the machine already knows from the spool's RFID chip and physically turn the machine around on a crowdwed bench in order to be able to access to push filament through the drive mechanism. Surely would be much easier to just have a prime function on the printer menu?

Setting the temperature at 150°C or 180°C is enough for all of UM filaments as far as I know, when it comes to doing a manual priming. And you do not need to push it through the feeder yourself, I would strongly advise against that as you risk damaging it, you only need to go to the Material menu and select Move, then you can move the filament forwards or backwards by rotating the wheel of the UM3. I'm not sure how this is done on the touchscreen of the UM5 though...

Thank you, I had no idea that that was what the move option  did, I assumed uit moved the print head!

Lol it is all electronic via Repetier's GUI, no mucking around with wheels
