  1. i also level my bed manually, then i run the bed test to check the pla consistency over the bed. its a good belt and braces check. you have to remember people starting out in the 3d printer world, you have to make it as simple as possible to start with, which cura does, then human nature makes us experiment more and more. for people starting out, they could easily unknowingly do the same and wreck their extruder wheel and setup. i am just pointing it out, i am sure daid has a million things to add, but if we dont tell him stuff,there would seem little point in having a forum.
  2. Fixed !!!! ok i lied a bit in my initial details, i have the hotend V1, i thought the latest one was V3 and hence i thought mine was v2. Anyway i stripped the hotend down, never been done since day one of my ownership and i have never had a need too either. it wasnt as much of a hassle as i had thought it would be. there in the peek is about a 1 - 2mm plug of PLA, it looks very insignificant on its own, but i recheck the head install instruction which asks for 8mm of bowden tube to be sticking out, mine was circa 6mm and the bowden had bite* marks on the outside as if it had been dragged th
  3. just an observation really, that caught me out. i have the ultimaker control panel, so when i print, i set my temperature on that and i set the cura temp to 0 degrees. i used to let cura set the temp but when i got the ultmaker controller, i was always getting the temp error each time i tried to print. (seems to be fixed in v13) i have been having some printing issues, not sure what yet, so i thought i would recalibrate the bed using the bed levelling check, but since i had set the print temp in cura to 0 it checked the four corner heights and when i set it to print the test square, it was
  4. i should of said, a different colour too! i ran a few tests again, with the new colour PLA, same results really. i calibrated the 100MM extruding check, mine was circa 102mm. i did back the spring, right off, on the extruding wheel upgrade. it did seem to be grinding up the new red PLA. it makes sense that it is underextruding, when the print first starts, it looks fine. the best part of the print is the apron! then it gets progressively worse, which would tie in with the pre-melted pla in the head running low. sadly i think i will have to take the head apart, can you tell i am not too
  5. Update, I tried printing at circa 240' same problems, I changed out the PLA for another reel , but from the same supplier and same age as the failing silver one, initially it looked good and I let it print for quite sometime, circa 220 degrees, but half was through I could see it was looking brittle again, so I stopped it and sure enough it was just like the other failed prints, very stringy looking and hence a weak print, it even breaks as I peel it off the bed. I printed some smaller parts, belt tensioner s but they too are so stringy and brittle, even though there does seem to be a good amo
  6. thanks for the replies - i can fill in a few of the blank details, i had already tried and looked at a few things on my ultimachine. one day i printed a 5 hour part with my usual settings, came out just fine. the following day i come to print the opposite handed piece, with identical everything, setting, same PLA, same Cura etc. twice on the bounce i tried it with the same de-lamination. i had looked at the e-stepper, as i thought i may have messed this up when using the ultimaker panel, this was 836, which is inline with alot of people with the extruder upgrade. i can turn the extru
  7. ultimaker with v2 hotend and the upgraded feeder. cura 12 / 13 ultimaker control panel, NO heatbed it all used to work just fine, now this week it seems to be printing very weak and brittle prints, they seem as if they are laminated. all the settings i previouslyused, no longer seem to work, i used to print with pla at about 215-220 now ive had to try to increase the temp to about 230-235 and seemingly still no success. the print seems stringy, i initially started the print at all default speeds etc etc. 0.2 layer height and the examples i am showing were at 80% infil, i used the ultipane
  8. you nailed it, one of the belts had a small-ish amount of play in it, tightened up and seems alot better now. these ultimakers require more love and attention than my wife! i wonder if i can sell her and get another Ultimaker, i may put the idea to her and see.
  9. How do I explain, say I have a picture frame shape with a hole in it,the edges form fine the hole perimeter seems to form fine, but but but, I've noticed of late a lot of my prints don't seem to infil fully. The perimeters seem to peel away from the infil, if that makes sense, it's as if the infil isn't overlapping the perimeters. I've reinstalled cura a few times and its The latest version. It never used to to this, the holes wouldn't be great before, but now the holes shell is almost always not bonded to the main part. It happens at 25% infil through to 100 %. I use PLA at about 220' I've u
  10. I use the cura software, with the marlin firmware, my min temp issues are currently gone, It seemed to occur after I bailed out on a failed print and I used to just disconnect the printer. If I used reset on cura, this fixed all my min temp issues. I have no links to cura software, but I suggest you use it, once you have done a few prints, you will not look back. Good luck
  11. Ok thanks that's very good to know, I had wondered what the reset was for. I think , before the error occurred, I had a poor starting print and I hit disconnect, while it was still running, ooooops. I don't think this will of helped. The first time I got the error , I may well of done the samething, not 100% sure, but I think it was on the back of me cancelling a print.
  12. Aghhhhhh I can see this being frustrating. I gave all the wires a good check and a wiggle the first time it happened, but it didn't seem to immediately fix it. Same thing this time, a bit of wire wiggling, a few computer restarts and clean install of software. I skipped the firmware update , just to eliminate one thing. It's back up and running now. I will hok it upto another machine for a work out too, I have some strange programming tools and drivers on the one it's running from. A bad soldered joint is in my mind, or a misfiring pcb. I've no idea where I stand on that one with ultimaker, a
  13. Ok my problem is back, for no apparent reason, printed off a few jobs all fine, left the computer on, no related software running, ultimaker turned off too, come to use , from a cold start and the same error is back. I would imagine installing the software package again will fix it, but I'd like to find the causes for obvious reasons.
  14. I thought cables too at first, everything seems snug and nicely cable tied, but I pushed everything home anyway. I had a panic thinking the mobo had given up already, then I remember windows doing an update in the time between a successful print and this error. I just reinstalled the cura and print run bundle again which put it back to working fine.
  15. ok,,,,i fixed it,,,,i re installed cura and printrun and seems ok again,,,,kinda strange
