Hello all, I am new to the forums and have an issue with my Hemera jamming....I've had it installed since first release and initially noticed that I would occasionally have to unload then reload pla otherwise the hotend looked to be clogged...this happened on the very first print so I heated the hotend, removed and reloaded and was able to print just fine. However almost each print job with pla required that I unload\load the same filament back in to have a successful print. Now I am at the point that the pla creates a small blob at the gears and I have to remove the entire assembly to clear the jam..All I did was install the v6 so I'm not sure what I could have done to cause this...The PTFE tube is fully seated and this is now my 9th or 10th time of having to remove the hemera to resolve the issue. I've tried 6 different brands of PLA but no matter what I do I end up removing the hemera to clear the jam....I'm just going to leave it off for now but hoped one of you gurus could offer some advice?
I should also mention that the idler screw is normally adjusted according to the instructions....it was removed in the pics above while taking apart the hemera
Hi John, Sorry to hear you are having issues with your Hemera, can you let me know what retraction settings you are using, and whether you have a setting in your firmware causing a long retract when the print finishes? Also, do you let the printer cool down completely before powering off, or do you immediately turn the printer off after a print has completed.
Thanks for the reply and unfortunately at this point my Hemera is completely seized. With no jam the idler gear will not move. I’ve been chatting with support and will see what direction they advise. But to answer your questions there is no retraction setting at the end of the print. This issue progressively got worse over the last few week to where it is now. Retraction was usually at .8mm but this issue occurred on very minor prints like bed leveling type stls. Thanks
Same problem here. its jamming with no clogging at all. the gears are jammed. need to dismatle the gears and but it back together to make for for 5minutes to several hours. i have only completed around 5 short PLA print and 2 TPU prints and now it does not let me coplete at all. tried same 3dmodell over 10 times now around 5 hour print and cant complete without the gears are jammed. Steppermotor is cold around 40-45C and i have even let it stand over night and still jammed with no filament inserted. have sent an e-mail to support about this, but think it will take a while to get answer so going to make a call tomorrow morning. have also checked the gears/cogwheels.. the looks all alligned. so they are not in the wrong space like some user have reported.
it sounds like both of you may have cracked gears, if you can email support@e3d-online.com with your order details and some images of your gears we can send out some replacement gears.
i have sent some images. ticket 38910 is that enough ? or do you need more pictures. have inspected the gears and i cant see any cracks. but can try to see under a magnifying glass lamp after work today. to take a better look.
Support will be able to walk you through some more specific tests that you can do to check your gears. There is a bit of a backlog at the moment so apologies if it takes some time to get an answer.
