    z-offset plugin

    in UltiMaker Cura

    Posted

    Ah yes could well be. tbh the offset is soooooo useful to have in the Slicer, for example I have more of an offset for PETG than I do for PLA and I can dial this into the profiles for each material.

     

    I am not sure if the plugin is actually broken from the post above are you ?, I truth I haven't tried changing the value as everything works for me, but doesn't sound like there is actually an issue ?. Would be a nightmare for me if it was actually broken ! ;(

    'Not in Skin' Combing behaviour

    in UltiMaker Cura

    Posted

    Hi,

     

    @smartavionics I guess this might be one for you ?

     

    I have noted some behaviour with the new implementation, when set to 'Not in skin' to extruder will comb within the walls which is great !, however when the 'max comb distance with retract' is exceeded then path it takes is still the same (within walls). even though it has retracted. For example I have the max comb distance set to 100, when this is breached the extruder retracts but the path it takes is still only within the wall, which can lead to an extremely complex and long path as it navigates the entire perimeter. 

     

    I was thinking it would be better to take a more direct route once the retract is triggered as its not actually coming at that point and would save this really long and complex perimeter navigation 

     

    Thanks

    I totally agree this is the single most useful feature added to Cura in a long time, its totally essential !, I level the bed then set the offset with this, I never have to mess about with the paper under the nozzle method. 

     

    I have tested a quick slice and it looks like its working to me on Cura 3.5, here is the Gcode snippet, my z offset is set to 0.1 and its working as it should. 

     

    G0 F4800 X47.118 Y97.868 Z0.5 ;adjusted by z offset
    G92 Z0.4 ;consider this the original z before offset

     

    Also I am not clear how @ahoeben you are adjusting this in firmware ? (I am using a 2+ BTW)

     

    Thanks

     

     

     

     

    More information during print

    Posted

    Hi, I installed for the first time and had a couple of questions, I noticed the retraction settings are no longer part of the material profiles rather there is now a single setting ?, how is it envisaged to be handled for different materials ?. Or does it somehow pick up the retraction per material but only displays it once ?. It didn’t seem to do that as the default was 25 and 4.5 but the set value for each material profile should be 25 and 6.5 on the 2+. What should I change ?

     

    thanks

    Thanks for the explanation, tbh I am not after the material profiles, I mentioned those in this follow up to Carlo as it was a chance he said was in, so was mentioning it was missing for his info really ?. 

     

    The 3.3 version FW seems to print well and the steppers actually seem quieter, is that a change gone in ?. Does 17.10 cover all this sort of stuff fron 3.3 ;). 

     

    Many thanks

    Well, if the delivered firmware is still version 3.3 it is very likely that the latest firmware changes did not made it into the 3.5 release of Cura.

    Some more research: according to the included list of commit-ids the last change for the delivered firmware was made in march, TPLA was added in June to the source repository...

    I guess, you have to wait a little bit longer for a new firmware release?

     

    Besides that: the only relevant change regarding the material change wizard is a new comment that explains why the material is pushed forward right before pulling it back:

    https://github.com/Ultimaker/UM2.1-Firmware/blob/UM2.1_JarJar/Marlin/UltiLCD2_menu_material.cpp#L152

     

     

     

     

    Thanks @tinkergnome appreciate your time, how are ahead is your firmware ?, are you based on 3.3 ?, I have not tired your version yet, do you generally patch up to the head revision from Ultimaker when they make a release ?

     

    Thanks

    Hi @CarloK, I have performed factory resets and flashed the firmware again and still 3.3 has the issue with grinding on material change. Also I do not see TPLA in the material profile. It looks like PP has been added as a material but not TPLA. Has the wrong firmware version made it into 3.5 ?

    Factory reset ?

    in UltiMaker 3D printers

    Posted

    I performed a factory reset on my 2+ and it didn’t power back up on its own, I left a for a minute or two then power cycled the actual power button and it came straight back on. Is this normal ?, or should it come back up after a factory reset on its own ?. I am using the latest 3.3 firmware. 

     

    Thanks

    4 weeks have passed and no replies.... Everybody is happy with the UM2(+) as it is?

     

    Here are a few things that will be in the oncoming release:

    Copied stepper module fixes from UM3 / Open source Marlin project:

    These fixes solve the problem where during fast movements you sometimes heard a loud tick sound like some mechanical hiccup was occurring.

    - Fix: the multiply routine could have an overflow, solved by adding a 24x32-bit routine
    - Fix: ensure the stepper interrupt triggers immediately again when it takes too long.

     

    Improve material import:

    - Fix: a material name length of 8 would crash the printer. Now consistently allow a length of 8 characters everywhere.

    - Fix: illegal values for the material retraction-length and retraction-speed are now set to default values.

    - Change: Improve error handling for very large positive or negative numbers.

     

    Other changes:

    - New: added Tough PLA (TPLA) material profile.

    - Fix: retract at end of print. Contributed by TinkerGnome.

    - Fix: another bug with retraction at end of print. If we were already retracted (G10), then we were retracting too much.

    - Fix: M117 was missing a character when printing via USB. Cherry-picked from UMO repository. Contributed by AmedeeBulle

    - Change: Changing material during a print is made 15 to 30 seconds faster by removing an unneeded filament heat-up (the filament is already hot).

    - Change: several menu's where the only option was to 'Click for return' now have the focus set to this button. This removes the need to first rotate the button and results in faster user experience.
     

    PLEASE REPORT PROBLEMS!!!!

    In the forums I see people complaining about no new firmware releases coming out, but when no problems are reported then we can't fix them.

    Report your problem at github or post it here, then I'll add it to github.

     

     

    Hi @CarloK,

     

    I have just updated to this version (3.3), and not seeing the TPLA profile, and also still see the behaviour when you change material that the feeder still pushes forward and grinding the filament before retracting back out for the change ?, has the new Firmware not uploaded corrected into Cura 3.5 ?

     

    this doesn't seem to be fixed either

    At GitHub there is for the UM2+ only 1 reported issue:

    - A problem with filament grinding after material change.

     

     

     

    Thanks

    Replacement Bowden Tube ??

    Posted · Edited by Link

    update on this one for anyone interested, I have one concern with the PTFE after using it for a while, you can feel more movement on the tube within the collet in the extruder end.  What I mean by that is when a retraction is is taking place you can feel the tube move slightly in the collet (I fully expect this to get worse over time), I have printed some thicker collect clips (the blue one) to pull the clamp higher and grip the tube tighter, but still (I assume due to the PTFE being softer) the tube flexes more than the standard UM version. At it stands I am not sure which works out better, slightly less resistance of the PTFE but also the increased movement in the collet. TBH I am thinking the standard tube is the better option as this movement m (even when slight) will make the retractions less accurate.

     

    in summary, this isn’t an improvement I would recommend.

    Temp difference for 0.6 Nozzle

    in Materials & profiles

    Posted

    How much temperature increase as people running for the 0.6 nozzle over the 0.4 nozzle ?, the default PLA material profile for Ultimaker PLA for example adds 10 deg extra for the 0.6 nozzle, however this seems like too much as it gets slightly blobby at this temp. 

     

    What are people using ?, is anyone changing the retraction settings for the bigger nozzle ?

    my bondtech PTFE tube arrived, I ordered 3m so that gives me 4 lengths of 75cm which is longer than standard so gives it a nicer curve. There is def less friction running filament through by hand and the overall quality seems very good, its the same OD as the Ultimaker tube so the collars grip the tube nicely. So far very impressed, not sure I will be able to quantity the affect on print quality, but all seems positive so far.
