[VERKAUFE] Fast fertigen, auf Skeleton3D basierenden Drucker (17x15x16 Druckfläche) - 9 Jahre zuvor

Verkaufe hier meinen fast fertigen 3D Drucker, der auf dem kleinen Skeleton3D Drucker basiert (http://www.thingiverse.com/thing:560353). Aus zeittechnischen Gründen komme ich leider einfach nicht mehr dazu diesen niedlichen Drucker fertigzustellen. Zuviele Baustellen Sämtliche Bauteile wurden nachkonstruiert und verstärkt. So einen hat niemand. Der Drucker der hier verkauft wird, wurde modifizi

Re: Sintron All metal hotend - Mechanics mirror-inverted ?! - 9 Jahre zuvor

So these prints were printed with a retraction setting of 4.5mm @ 80mm/s. In the end of the print you can clearly see that retraction settings doesn't deal with the heavy oozing. This excessive oozing might result from the preasure built up inside the hotend and as there are no retraction commands once the print is finished or as there is no PTFE inliner inside the hotend, the (PLA) plastic melt

Re: Need some help to tweak the prints - 9 Jahre zuvor

Quotedislegal After setting max jerk to 15, I still had layers shift. I have checked the tension of the belts - they seem right. Any tighter and it becomes difficult to slide the print bed. I have checked the pulleys and they seem tight on the motor axles. After setting max jerk to 10, I had a successful print of a test Marvin without any layers shifting. Although he is a little droopy on the ri

Re: Need some help to tweak the prints - 9 Jahre zuvor

Don't jump at my throat but are the pulleys all fastened? Are the belts all tight and fixed? This layer shifting typically results from loose pulleys. Even though the cube printed nicely before. EDIT oops hit send too late.

Re: All metal hotend - Mechanics mirror-inverted ?! - 9 Jahre zuvor

Of couse I tried different retraction settings. I asked the vendor himself and he stated that they print with 2mm @ 35mm/s. I have turned it up to 40mm/s and haven't seen any improvements. I still haven't disassembled the extruder. 80mm/s is something I wouldn't have gone by myself. But I am always open to suggestions. Did some research on the interwebs and haven't found *any* information whatso

Re: Sintron All metal hotend - Mechanics mirror-inverted ?! - 9 Jahre zuvor

Okay. I will fall back to my good old DIY wade extruder. Also it is bigger then the Sintron extruder I have a bigger print area and prints come out in higher quality. I'll disassemble this MK8 extruder. The motor and the mk8 pulley should find another use. 50€ for a stepper and a mk8 pulley is quite the deal. Lesson learned.

Re: Occasionally temp sensor defects - Tried several thermistors - 9 Jahre zuvor

The thermistor came with a wire attached. 1) Solder joints look okay. 2) I crimped the connector at the end of the cable myself. I'll check on that. Maybe some bad connection there. 3) Wires to thermistor glass bead seem to be soldered. The connections are covered with shrinking tube. 4) Cable is okay. I just did a print without temp sensor defect issues. Also changing temperature while printing

Re: Sintron All metal hotend - Mechanics mirror-inverted ?! - 9 Jahre zuvor

More pictures of oozing and now also with stringing. YAY. I am getting there. Retraction settings in Slic3r. Distance = 2mm Speed = 40mm/s Travel speed 80mm/s Print temperature= 200°C in the beginning. Then set it down to 193°C. Print interrupted because of Communication Timeout. Board = Teensylu v0.8 - I wonder if this piece is starting to die. Would have been a wonder if cheap stuff from over

Re: Occasionally temp sensor defects - Tried several thermistors - 9 Jahre zuvor

I am not applying couple of hundred volts No. With "it reads nothing" I mean there is the same number on the multimeter as when both pins point into the their. I don't read 0 ohm. I just finished another print and I updated my first post above. At 200°C the thermistor reads 35kOhm on the connector to the board. Yes the thermistor on the new hotend is completely new. It came with the extruder

Printer: Prusa i3 Controller: Teensylu 0.8 Thermistors: Several thermistors from different hotends. Software: Repetier Firmware: dunno. used to run for the last 1-2 years perfectly. I have this problem that sometimes when I want to print the printer says "Extruder 0: temp sensor defect" and switches into dry run mode.

Oozing after finished print - 9 Jahre zuvor

I have now set retraction to 2mm at a speed of 40mm/s. Looks better as far as you can say this after one print. Still, when the print finishes the hotend oozes out alot like shown in this picture I haven't had this issue with my E3D V6 clone on a Wades extruder. Any ideas?

Re: All metal hotend - Mechanics mirror-inverted ?! - 9 Jahre zuvor

I had forgotten to set the z axis to 0 and this failed print came out. The nozzle started to print 10mm above the print bed. As of yet, this is my best fail print...

Re: All metal hotend - Mechanics mirror-inverted ?! - 9 Jahre zuvor

Yes it's from Sinton. Dual extruding. Now I get it. I don't have endstops installed. O Lampe, what settings do you have for retraction? Before I used a geared Wade extruder and those settings clearly do not fit. It oozes alot and sometimes because of this the threaded hotend runs empty and air is being extruded. Nevertheless, when it prints, the results are okay. My setup before was a cloned e

Sintron All metal hotend - Mechanics mirror-inverted ?! - 9 Jahre zuvor

Hello Community, I have ordered an All-Metal-Extruder : As I have realized the same extruder goes for less then 50€ what I have paid. But this only as a side-note. When it arrived part of the fan was broken out and one cable came loose. The vendor is very attentive and send a replace fan. So no big deal either. But when I wanted to install the extruder some strange feeling did overcome me...

Re: Hotend fan pin controlled - 10 Jahre zuvor

Thanks for the answer. So the "Extruder Cooler" is a different function from the default fan that cools the print itself ? Did I get you right? This is my clone It came with ribs. I came without PTFE inliner. When running the hotend one single minute without cooling by the 30mm fan, it jammed instantly. I actually ordered a new thread with PTFE inline and it worked way better (without cool

Re: Hotend fan pin controlled - 10 Jahre zuvor

Hey! You are not alone. I have found this feature (extruder cooler) right now but I am not really sure how it works. Configuration: I have an All Metal Hotend (E3D clone) 1.75mm with a PTFE inliner. Printing PLA on a hotbed. Teensylu controller. The hotend is cooled by a 30mm fan. The print itself is cooled by a centrifugal fan. So, two fans. Right now both fans are connected to the one defaul

Re: [DESIGN QUESTION] Z axis table - Skeleton3D mod - Where are the Engineers ? - 10 Jahre zuvor

Okay so here is the complete Z axis. I hope I didn't forget anything. These are the parts for building the support platform for a (generic) build platform but are especially made for a bigger version of the Skeleton3D. I can add the parts that hold the smooth rods and the motor as well. I also remodeled the X and Y motor holders to a much stronger version. Also the pulley holders are remodeled

Re: [DESIGN QUESTION] Z axis table - Skeleton3D mod - Where are the Engineers ? - 10 Jahre zuvor

This becomes more of a buildlog than a resourceful help thread so here you go with more pictures and printed parts. I assembled them and they fit perfect. NOW the build platform, no matter if it is a thin aluminium plate or a 1cm thick wall tile, is stury. The original one really was not stiff at all. Even in tiny and transportable scale. Maybe this one now is a bit overkill but rather over kill

Re: [DESIGN QUESTION] Z axis table - Skeleton3D mod - Where are the Engineers ? - 10 Jahre zuvor

Yeah sure. Taking the upsize in consideratin it is not that tiny anymore. Transportable ? Clearly. 30cm cube. I wanted to use the head bed but I already have removed the silicon head pad. Though as I don't have an aluminium plate around I thought I could go back to the basalt thing. Anyways I have now come up with a support platform that is rigid enough. Thanks !

Re: [DESIGN QUESTION] Z axis table - Skeleton3D mod - Where are the Engineers ? - 10 Jahre zuvor

Okay so I reduced the width of the arms to 10 mm and rotated the bearing holder 90° so that the bearing can be clamped in with two screws. The overall print time is now reduced to around 5 hours for both parts. I also increased the outer perimeter print speed to 45mm/sec from 30mm/sec. stl

[DESIGN QUESTION] Z axis table - Skeleton3D mod - Where are the Engineers ? - 10 Jahre zuvor

I'm in a dilemma. I'm building a Skeleton3D printer (link) but at a slightly larger scale. I want to use my 'basalt' heat bed from my old TwoUp. The original design of the Z axis is too weak for that build platform. It warps and bends, it wobbles and jiggles. I started to construct my own design in Fusion360. I now have two designs at hand but I am not really sure about them. I am by no means a
