Thanks for all the responses I think that my problem was PLA with the all metal throat yes As fixing that meant waiting on the post I have ordered a j-head instead, and it is currently printing better than the E3D ever did, and this is on a non levelled, roughly guessed height print bed, so I think my mentality/set up is just more suited to the j-head. I will revisit the E3D one day when I needby jimmyclarke - General
Hi all, I am having real problems running a hot end without getting it jammed, I am beginning to think it might be my filament, but before I chuck it out, are there any obvious steps I am missing? Scenario E3D v6 hot end, all metal 1.75mm throat, with a bowden tube and cooling fan in place. Printing with PLA The cooling fan seems to be doing the job adequately as all the fans are cool to theby jimmyclarke - General
My assumption is (and someone please correct me if I am wrong!) But it is ready to compensate for the leveled bed when you have a z-probe, as it will need this travel for the compensating factor? Have you got autobed enabled? If so does disabling it stop this behaviour?by jimmyclarke - Repetier
I have just switched to a bowden set up I used this mount for the extruder: It uses existing holes and bolts so no modification is needed, couple that with a hot end holder suitable for your carriage and you're away! I am happy with my set up, still calibrating the auto probing (what are they calling auto bed leveling these days?) But have printed out a go pro mount prior to the calibrationby jimmyclarke - Prusa i3 and variants
@gamma1148 Glad to hear it has been done thanks @J-Max should have mentioned that the one I used as an example wasn't the one I was going for, just first picture that showed what I meant rather than me try and describe it. You have won me over though and just ordered a E3D v6, that hopefully I can couple to my wade extruder long enough to print out a replacement (really liking the thingiverse oby jimmyclarke - Prusa i3 and variants
Hi, I after battling with clogging I am changing my hot end, I really like the concept of the hot end being directly attached to the feeder like this: But with my printer out of action I have no way of fabricating a mount, as my carriage has 30mm spaced bolts, a metal nema holder like this: should work perfectly. Is this viable? Has anyone tried it and would recommend it? Thanksby jimmyclarke - Prusa i3 and variants
Hi Thanks for your response, after reading what feels like every internet page on auto leveling I finally found where I was going wrong! I had been homing using Repetier and it's individual buttons for X Y and Z as I figured that's be the safest option, but I just saw when homing all axis (G28) In the comment for Z homing, so I pressed the homing button for all axis at once and voila! it now pby jimmyclarke - Prusa i3 and variants
Hi, Sorry if this belongs in software, but I thought as it's relevant to a prusa it would fit here I have installed an inductive probe to my extruder, this works fine, but I am struggling to change the logic to accommodate this change My problem is I don't have anything directly under the probe at X0,Y0 to trigger it. Instead I have set 4 probe points so I will be able to use auto levelling Iby jimmyclarke - Prusa i3 and variants
Hi, Sorry it is for a LJ12A3-4-Z-BX to replace my z endstop I got that diagram off here, where other people have wired it up that way effectively, but I am having problems. EDIT: sods law, just came back to it and it is now triggering properly...by jimmyclarke - RAMPS Electronics
Hi, my 12v aux as pictured below is only outputting 6.7v, I checked and there is a steady 12v going into the board, Is there any jumpers I need to engage/ change to get this to be 12v? Many thanksby jimmyclarke - RAMPS Electronics
Yes my esteps are correct, this is me printing a mount for direct feed so I am still running the hobbed bolt and there was no retraction on, and no noticeable skipping (which doesn't say much I know) Cleaned nozzle to no avail, now all my prints look like the worst part of my previous picture, the annoying part is you can see when it just stops working nicely, it's like I've taken a month step bby jimmyclarke - Prusa i3 and variants
Well I adjusted the pot a smidgen to the right and now no axis drift and printer is still quieter than when I started, so very happy Now though I ended up with this, (think it still fits the thread topic) All settings are the same from when I printed the first piece that drifted, so I don't think it's the temperature? What do you think?by jimmyclarke - Prusa i3 and variants
Ah that makes sense, I had turned that pot down to reduce noise! Thanks I will get it sorted. In terms of using a non conductive screwdriver, I can confirm the importance as I blew a driver up with a metal screwdriver!by jimmyclarke - Prusa i3 and variants
Hi, Not that I am the best to answer as I would state my prusa i3 is about 90% functional but... Have you tried adjusting the pot for the extruder (I'm on RAMPS so sorry if that doesn't apply) When I had issues with my extruder, I was able to plug it into the x axis and it worked, so I I played with the pot until it matched the extruder, but before this I had to change the order of the wires iby jimmyclarke - Prusa i3 and variants
I'm currently struggling with my hobbed bolt, so I am switching to a direct feed. Woke up this morning to find my new extruder has printed, but twice there has been a shift causing it to print crooked, (it should of looked like: ) As my hobbed bolt eats my filament, my prints are failing more often than not, so I don't have many examples, but the failed 3DBenchy to the left also shows this drby jimmyclarke - Prusa i3 and variants
Hi Everyone, Sorry to ask this as I know there are other posts, but I just want to (triple) check this before subjecting my printer to torture! I ordered the orange tipped LJ12A3-4-Z-BY but received the blue tipped LJ12A3-4-Z-BX instead, and the seller is refusing to admit fault. So before I push the return issue further, I wanted to see how I could use it. Are any resistors needed, or will thby jimmyclarke - RAMPS Electronics
Hi all! Sorry for the delay, the sun is out in Britain and as summer only last a few days at a time, we have to make the most of it when we can! Yes, when the filament jammed it ended up trying to push the hotend out of the way which caused it to become wonky I have tried to adjust it back but it now seems permanently loose, so I think I will bore out one of the retaining bolts for it out to 4by jimmyclarke - Prusa i3 and variants
OK, well I think I have my problem diagnosed I checked all my esteps and am happy with the calibration So I printed out a test cube at 0% infill and got this During the time it was looking perfect I left it, and came back to the mess at the top! I had a look at the extruder and the whole filament had not snapped, but the hobbed bolt had cut away all the filament it could reach, so there was jusby jimmyclarke - Prusa i3 and variants
Thanks guys, My extruder came ready assembled and had the tape as you see, do you think it is worth taking this tape off then? Unfortunately my kit did not come with anyway of mounting a fan near the extruder, this is one of the things I will be printing Great advice coming in, looking forward to getting back to it tonight Thanks Oh and SteveRoy, my extruder motor does have a flat spot on theby jimmyclarke - Prusa i3 and variants
Hi Olaf, The dark spots are indeed gaps, the filament is kept in a sealed bag with silica gel in it when not in use, and there was no popping noises when printing, so I am hoping it is not that, and simply my settings are wrong. I will get more details on first layer etc. next time, thanks.by jimmyclarke - Prusa i3 and variants
Hi Sarf24k Thanks for the response! In terms of terminology, I'm not sure if I mean perimeter or wall, I set perimeter to 3 in slic3r so figured that the part of the print that isn't the infill was called that, but wall makes sense! I have all the speeds set to the same value, but different processes to the layer (edge vs middle) still print at different speeds. I will try lowering the temperaby jimmyclarke - Prusa i3 and variants
Hi all, I'm new so be kind please! I have built up a prusa i3, nothing special nor modified (yet) I have it at the stage where it can produce "functional" pieces, I am currently creating a spoolholder from http://www.thingiverse.com/thing:370390 Part 1 came out with the correct dimensions, but the infill is seriously messy! All my speeds are set to 30mm/s this was at 0.28mm line height, (goiby jimmyclarke - Prusa i3 and variants
