Filament slipping with buda style hot end I have a wade's extruder with a homemade hobbed bolt. I got a new hot end (the buda style one form Gadgets 3D) and the extruder is struggling and the filament is slipping. I was using a J-Head MK-V hot end and it worked perfectly (but that got messed up so had to replace it). I noticed that buda style hot end does require more force but am not sure if it is my hobbed bolt or the hot end. It could be that the hobbed bolt isn't gripping enough to produce the force or it could be that the buda hot end is just faulty (i've read reviews stating its one of the better hot ends). It could also be something else. What do you guys think?

Will buy the glow in the dark PLA. That looks cool.]]> Farhan Reprappers Wed, 05 Mar 2014 21:31:15 -0500 https://reprap.org/forum/read.php?4,316207,319882#msg-319882 Re: Filament slipping with buda style hot end https://reprap.org/forum/read.php?4,316207,319882#msg-319882

However, I cleaned out the hot end. Drilled it out with a 3mm drill. Made it nice and smooth. Used my brand new 0.5mm nozzle. Put a fan to cool down the cold end. Raised the temp 10° so at 210° for PLA (which I might lower later, print isn't the best quality). Tightened the crap out of the idler springs on the extruder so the bolt really gets a good grip. and I finally managed to get a successful print. The print was a good long 3 hour print. Nothing overheated or broke down so that was good.

Well I am out of PLA now so have to use the ABS to print. What temp is the best to print ABS at?]]> Farhan Reprappers Tue, 04 Mar 2014 16:30:56 -0500 https://reprap.org/forum/read.php?4,316207,319585#msg-319585 Re: Filament slipping with buda style hot end https://reprap.org/forum/read.php?4,316207,319585#msg-319585

What do you mean by setting the thermistor table for the buda?

With in your configuration.h file you have to set it for the correct thermister, so it reads your temp correctly. After you have that correct, you can run the auto pid, to configure for temp control.]]> cat.farmer Reprappers Tue, 04 Mar 2014 10:22:44 -0500 https://reprap.org/forum/read.php?4,316207,319246#msg-319246 Re: Filament slipping with buda style hot end https://reprap.org/forum/read.php?4,316207,319246#msg-319246 Farhan Reprappers Mon, 03 Mar 2014 16:41:22 -0500 https://reprap.org/forum/read.php?4,316207,318837#msg-318837 Re: Filament slipping with buda style hot end https://reprap.org/forum/read.php?4,316207,318837#msg-318837 svalsorim Reprappers Sun, 02 Mar 2014 22:41:56 -0500 https://reprap.org/forum/read.php?4,316207,316678#msg-316678 Re: Filament slipping with buda style hot end https://reprap.org/forum/read.php?4,316207,316678#msg-316678 cat.farmer Reprappers Wed, 26 Feb 2014 22:09:25 -0500 https://reprap.org/forum/read.php?4,316207,316544#msg-316544 Re: Filament slipping with buda style hot end https://reprap.org/forum/read.php?4,316207,316544#msg-316544
The j-head is a lot easier to extrude compared to the buda but I cant use that.

I even drilled the buda out a bit to make the filament flow through better. It did a little bit but not a lot.

How much force does the buda need anyways? If they are all the same then I might just have to find a way to increase the force outputted by my hobbed bolt.]]> Farhan Reprappers Wed, 26 Feb 2014 14:26:09 -0500 https://reprap.org/forum/read.php?4,316207,316528#msg-316528 Re: Filament slipping with buda style hot end https://reprap.org/forum/read.php?4,316207,316528#msg-316528
I couldn't extrude for anything with my wades and j head and now i run the wades and buda style and i haven't had an issue since.

These machines are possessed i think.]]> makovai Reprappers Wed, 26 Feb 2014 13:47:28 -0500 https://reprap.org/forum/read.php?4,316207,316229#msg-316229 Re: Filament slipping with buda style hot end https://reprap.org/forum/read.php?4,316207,316229#msg-316229 cat.farmer Reprappers Tue, 25 Feb 2014 23:41:32 -0500 https://reprap.org/forum/read.php?4,316207,316207#msg-316207 Filament slipping with buda style hot end https://reprap.org/forum/read.php?4,316207,316207#msg-316207
I was using a J-Head MK-V hot end and it worked perfectly (but that got messed up so had to replace it).

I noticed that buda style hot end does require more force but am not sure if it is my hobbed bolt or the hot end.

It could be that the hobbed bolt isn't gripping enough to produce the force or it could be that the buda hot end is just faulty (i've read reviews stating its one of the better hot ends). It could also be something else.

What do you guys think? Any tips?]]> Farhan Reprappers Tue, 25 Feb 2014 21:23:51 -0500
