I just last night discovered the problem ... and as I'd suspected all along, it was indeed USER ERROR. I just couldn't nail it down, until I realized ... When I'd ordered the new PTFE heat break from Amazon, I'd mistakenly ordered 3mm not 1.75! I guess I've taken apart and reassembled the hot end so many times over the years I just hadn't noticed. I don't mind having a good laugh at myself whby papilio - General
Thanks for the reply tray. Yes, the heat break is new right now and I've tried three. But I'll look into the other issues, though it is assembled correctly, as in nozzle not against the heater block. Also, I tried one w/o the PTFE, same problem.by papilio - General
I'm suddenly experiencing bad jams over and over. I've changed nozzle and heat break twice, disassembled and cleaned out the V6 hotend several times but immediately each time I try again the thing jams. I've been printing with good success for three years and many hundreds of prints, never seen anything like this. Using CarbonX PETG, my favorite filament for mechanical components.

You solved it Simon, many thanks!!by papilio - General
QuoteDjDemonD Can I just check you do not have deployprobe.g or stowprobe.g (or similar) files on your sd card on your Duet? Hi Simon, thanks for the response. Yes deployprobe.g and stowprobe.g remain on the card. Remove them?by papilio - General
Quotedc42 Those are indeed very odd probing movements. You didn't say whether you are attempting G31 auto calibration or G29 mesh bed probing. If it's G31, please share the contents of your bed.g file. Also please share your config.g file and firmware version. Thank you for helping with this David, I've posted the requested files on my post on the Duet3D forum for you. I've been using auto caliby papilio - General
Quoteo_lampe I've never seen such a weird probing behaviour with RRF before. Did this printer work before you installed the z-probe? How does the z-probe config line look like? How did you generate the bed.g file? I know! So strange that I was expecting a quick solution from somebody more experienced, but better minds than mine are still working on it. The printer is not yet fully commissioned.by papilio - General
QuoteMoriquendi I can't work out what on earth its doing in that video, half the movements and probes seem unnecessary to me but then I'm not familiar with how RRF does a delta calibration. Have you tried moving the head to various positions around the perimeter of the bed and manually calling a Z-probe? Idris I know, it all looks mighty odd to me as well. Far as I can tell at this point, thoseby papilio - General
I have a Universal board. Yes false triggering was my initial thought as well, even though the blue LED seems almost never to flicker now that I've tweaked the setup. But I've tried playing with sensitivity with no improvement so far. Just to deepen the mystery, that error message is no longer appearing. Here's a new video with a different bed.g configuration showing things a bit more clearlyby papilio - General
Hi Idris, and thank you! The video is depicting the behavior quite accurately, there's no flickering of the blue LED on those probes at the 7 o'clock position. The failed probes appear to be responsible for generating "Error: Z probe already triggered at start of probing move".by papilio - General
I'm just beginning to set up the piezo probe which I received some time ago from Simon, so I'm sure that there will be a few questions on the way over the next couple of weeks. Due to a number of design considerations I'm currently planning to utilize an underbed piezo setup. Sensitivity at this point looks great, quite a bit better in fact than what I was seeing with the hotend piezo. The firstby papilio - General
Thank you Srek, very helpful info to both my and Brian's requests. I'll be trying one out.by papilio - General
Calling out to Srek -- I've just come across your blog on running the Merlin with forced air cooling of the hotend. I too am using an aquarium air pump for part cooling, there's plenty of output remaining unused at the moment which would seem just the thing for keeping the hot end cool. I'm not quite able to tell from just the photos exactly how you've implemented the cooling around the hotendby papilio - General
QuoteSrek I'm talking about this one Okay thank you Srek, I'll be waiting!by papilio - General
Ah yes Srek, that's the main site I've been pouring over, impressive work! I appreciate the lovely machining. So is it the V3 which has not yet been released, or is there another on the way?by papilio - General
Oh, and right Srek, it was the Protoworx site being down to which I was referring. May I ask, which is your site?by papilio - General
Thanks so much Srek, was hoping I'd hear from you! I may just order one from RRD until the new model becomes available. Looks like a great unit!by papilio - General
Is the Merlin available from a US seller? In fact is it still around? The website appears to be down. Thanks!by papilio - General
QuoteMoriquendi Got to keep innovating, it's the only way to stay ahead of the cloners Yeah, I feel for you guys. Seriously. And at the prices you and Simon are selling these I can't understand anybody messing around with the clones!by papilio - General
Yes, the digital dentist, that's my position as well. My very many frustrations with the inexpensive printer I have, along with the eventual happy successes, have convinced me that in 3D printing technique and a very thorough understanding are vastly more important than the instrument used. I guess I've just been hoping that for my friend's sake I may not know the complete picture, that there mby papilio - General
Thank you very much for the reply Dust! I recall there being a couple of videos which did show the owners using other filaments, ProtoPasta's CF for instance, and saying that using non-Dremel stuff in their machines just voided the warranty. OTOH you do know your stuff, and I'd never claim to vouch for the accuracy of what's on YouTube. I'll be sure to pass that concern on to my friend. Inby papilio - General
Wow, there you guys go again! Great job Idris and Simon, I love the way you've incorporated and rearranged the piezos onto the PCB. Regrettably I haven't even reached the point in my build of installing my Piezo20, I happen to be currently re-designing the entire effector assembly so your timing with this is perfect!by papilio - General
A good friend of mine, a university microscopist, is interested in getting into 3D printing chiefly as a means of allowing in-house fabrication of various technical components for his work. He's been researching machines in the ~$2k range in hopes of finding a printer which comes as near as possible to just working out of the box, as the demands of his schedule might make it difficult to commitby papilio - General
Thank you sliceheart. I've decided to complete my delta project as a single material machine, dual filament will be phase II. I have both a Chimera and a Prometheus, I'll likely try both when the time comes.by papilio - General
QuoteDirty Steve Beta tested the Hybrid. FAR too delicate, extremely thin walls behind all thread connections, Twisted threads off of a nozzle, snapped the heat break. OVER engineered without durability. Thanks for the input Dirty Steve! Oh well. It did look so lovely on paper. So I take it then that the company has closed its doors? I find it sad whenever that happens ... knowing wellby papilio - General
Very cool, thanks Simon. Leave it to Josef!by papilio - General
Thanks for the input o lampe! Means a lot to hear views of people such as yourself with plenty of experience as I work on designing the first machine of my own. So yeah, that's the impression that I'm getting -- my hope is that the urge for soluble support isn't going to be too great. I've picked up both a Prometheus and a Chimera but at this point doubt that I'll design them in. Still, I cby papilio - General
Oh my Simon, that is quite brilliant! So much so that I find it amazing that it's not already become the norm. Just thinking out loud here, but would that not still require the priming tower to keep up with the print layers? Perhaps we could still save a lot of time by making the unused layers of the tower out of mere support structure in the primary material. I've been so exclusively infatuaby papilio - General
Does anybody know whether the company is still around? I'm pretty excited to see the hybrid of theirs, but the website is down and they've not posted anything to their facebook page for quite some time. I hope they're just hiding and deep at work!by papilio - General
