New Ratrig 400 with the “standard” configuration of Bondtech BMG and E3D V6 on an EVA mount. This leaves a small gap between the extruded and hider sink, and specifies a 62mm ptfe tube between them. I’m using the blue Capricorn PTFE tubing. I can’t get it to extrude properly without jamming. I’ve made sure the hotend fan is on continuously at 100%. I’ve tried four different spools of PLA from different manufacturers and in different colors. I’ve tried two rolls of PETG with even less success. Measuring filament movement into the extruder suggests that the steps are properly calibrated (i.e. 50mm gives me 50mm of movement consistently). I’ve tried temps from 195 to 255 degrees with PLA, and 220 to 255 with PETG retraction settings I’ve tried between 0 and 2mm with speeds between 20 and 40mm/s I’ve lost count of the clogs, several dozen at least. I’ve had to make replacement PTFE tubes, and varied the lengths up and down by several mm in approx 0.5mm increments I’ve tried cleaning the nozzles with a torch, and at least six brand new nozzles. I’ve tried oiling the PLA. This is my third printer, but has had 10 times the trouble of the others. Zero successful prints. I’ve gotten a couple of calibration cubes to finish, but they are severely under extruded and look “moth eaten “ as if they’d been out in the weather for months any suggestions before I just start over with different hardware?
No reply, and looking elsewhere on the troubleshooting forum others have had no reply as well for similar (and other issues) No reply from the online help form with E3D after more than a week. I'm moving on from the E3D hardware, have ordered a mosquito hotend from Slice Engineering. I'm posting this for others who may be considering a purchase. I know a lot of people have successfully used the hardware, and I also see a lot of problems on the various forums. It may be that some parts work and others don't, but in any case there doesn't seem to be any after sale support available. I reached out to Ratrig, and they pointed out that they no longer include the E3D V6 in their "standard" configuration.
Sorry to hear you're having issues and apologies for the delayed response, we are usually more active on our Discord community these days where we're happy to help in real-time. As you can imagine, combining different parts in machines creates a lot of variables to account for, so it's natural people have different experiences. We stand behind our reputation not just for quality products, but for customer service too. From the information you've provided I would surmise the following situations: Some material is caught in the filament path that falls just outside the hotzone and therefore isn't able to heat and extrude properly PTFE lining inside the nozzle is damaged causing extrusion issues The cold side isn't adequately cooled, causing heat creep: check the orientation of the clip-on fan, and try turning the clip on bit 180 degrees. If you decide to continue troubleshooting this issue, do get in touch on Discord and we'll do our best to get it right. Pictures are always helpful for troubleshooting, too! It's easy to share them there.
Fair enough, but as far as I can tell there's no mention of discord on your website. I tried submitting the (excruciatingly long) help form with pages of questions, but got no response after a couple of weeks. Searching online for "E3D forum" mostly brings me here or reddit. RatRig said they'd reach out to you for a warranty claim, but agreed that tossing the V6 and getting a better hotend was the right move. A mention of the discord on the website with a link would have been helpful I agree that something caught in the filament path is plausible. I have replaced every part of the path dozens of times. I've used up almost half a meter of PTFE tube, a bit of it was the cheap generic stuff that originally came with my ender, most of it was the blue Capricorn stuff. I've tried carefully cleaning the nozzles, using a torch and solvent, and have swapped in at least six brand new nozzles. I've checked the temps with a known good thermistor, and tried a very wide range of temps. I've made sure the fan is running at 100% all of the time, and tried two different fans (only had one spare on hand). I've tried varying the extrusion speed, printing speed, and any other parameter I can think of. Dozens of times is not a typo, I mean that literally. I've read every troubleshooting guide I can find online and tried everything suggested. I'm done trying too make this thing work at this point, just too frustrated and starting over with better hardware. My cheaper printers just worked, lots of fiddling to get good quality, but from the very first try I could always make parts. The E3D V6 has failed to make a single successful print, except for the two calibration cubes that looked awful. At least the parts of the cubes that did print were dimensionally accurate. Currently the V6 is off of the printer, so badly clogged that I can't get the PTFE or the filament out. I do have a mill and a slitting saw so I think I'm going to dissect the thing to see what's wrong with it.
