I hope someone can help me out. I have a makerbot replicator 2x which I am having problem with. Why does it start printing ok and within an hour of printing nothing is coming out of the nozzle?
@Shorty_s_3D_Workshop sounds like over/under tightened extruder or a partially clogged nozzle. Google (bukobot cold pull) for a guide to help clean the nozzle.
Thanks Rob. I will try it
Or it’s heat creeping up the hotend.
Michael I have no clue what that means…I am new to the 3d printing so I don’t know the lingo yet.
Which filament do you use?
This is a common problem for the replicator 2/2x when you use pla. But it can also happen with abs of course. Normally the problem is heat creaping. To be honest, the rep2/2x have very bad extruders.
I am using abs filament
What temp are you printing at? Try increasing the temp by 5c if that fails 5 more. Don’t go over 250c if that doesn’t work try deducting 5c from the original value. Don’t go under 215c. Does it print the entire first layer? Are the bed screw’s loose enough to further loosen themselves during a print? Please link some pics of the filament while in the extruder during a jam. And if it is grinding the filament show a pic of the ground spot. Make sure to remove all debris from the hobbed pulley. Measure your filament with calipers in many spots and all the way around the filament in each spot. If there is a section over 2mm for a 1.75mm filament or 3.2mm for 3mm filament the filament is trash. It mask be rubbing too tight in the Bowden tube and excessive force causing the jam. let me know if none of this helps. First make sure you cleaned all plastic from the Hobbed pulley and then set the proper filament diskette average from your calipers.
One other thing that sometimes works with the replicator 2/2x extruder :
Remove the whole extruder from the print head. This means remove the screws from the fan. Make the 2 screw on the extruder plastic housing slightly loose. Then press the plastic housing against the filament driver wheel and tighten the screws from the plastic housing again. The put the motor back on the print head and tighten the fan screws again.
During this procedure the filament have to be removed. And it’s a good idea to do this while the nozzle is hot because then you can use the moment to press a 2mm drill (or something similar) through the filament guide to clean the whole channel till the nozzle.
I don’t think we should help takerbot owners. It’s cold, but if we help them we are helping takerbot with free support even though they patent our open source designs. @ThantiK what do you think? Too harsh?
@Matt_Kraemer that would make us as bad as them. Everyone knows I hate #Takerbot but first and foremost we are a community of makers who help each other out of trouble (most of which springs from bad or uneducated decisions, yes, like buying from Takerbot). If @Whosa_whatsis pissed us off would we withhold help from bukobot owners, or if @Brook_Drumm did likewise would we not give advice to printrbot owners. I am solidly android but wholeheartedly help people jailbreak and learn Cydia.
@Matt_Kraemer if we do it like this then we are no better than #takerbot Help the guy, he is not responsible for this s…t, would pitch in myself but dont know anything about mbi’s
@D_Rob , my opinion is that we should help MakerBot users with pre-stratasys machines, but not post-stratasys machines.
To be honest, I’ll never buy something from takerbot again. But in my case the primary problem is the quality. The machines are very bad designed. And now I know that the price is way too high. Especially because the most of the ideas are stolen from the community. But I don’t want to through my replicator 2x out now. I think it’s a good idea to help these people. This way you can show them how bad the machines are designed
