Single line calligraphy/handwriting fonts? - 5 years ago

Hi, i have recently been playing around with using my printer as a plotter and I got asked to draw some invitations. If I google single line or open contour fonts I find some but Im looking specifically for something that looks more like calligraphy. Has anyone ever come across some good looking fonts like this? Cheers

Re: good and bad perimeters in flex prints - 5 years ago

update: turns out its the temperature. I had to lower the temp by 10C and now the extrusion is buttery smooth. dont ask my how the temp apparently dropped so much without triggering runout errors, but now it works.

@digital dentist: that could be something. im using duet and ill do a print with relative extrusion tonight. thanks

Re: good and bad perimeters in flex prints - 5 years ago

maybe, earlier versions of this model i printed with 25mms and my setup can handle that and it still looked bad also speed would not explain why only certain parts are bad because the perimeter speed doesnt change this is screenshot from cura, the outer wall speed looks consistent

good and bad perimeters in flex prints - 5 years ago

Hi, Ive been printing in flex materials recently and i've observed this weird behavior. The outer perimeter looks pretty bad and patchy but then for a good portion it looks normal. The perimeter speed is around 10-15 mms and I see no other underextrusion artifacts. Top surfaces look normal. The good and the bad portions are the same all around the model and I cant see any reason why this pa

Re: Toy gun trigger mechanism? - 5 years ago

Yes, that sounds like something usable. I have a rough sketch of the mechasim, and in this vid you can see the trigger through the housing. I just dont want to reinvent the wheel and calibrate distances over several prototypes

Toy gun trigger mechanism? - 5 years ago

Hi, Im looking for a trigger mechanism that can repeat itself without the need to cock the firing pin. I basically want to hit a bell repeatedly. I remember that toy revolvers like this have exactly the kind of action i need. Has someone come across a model or drawing of such a mechanism somewhere?

Start script variables for cura, prusa, s3d etc - 5 years ago

Hi, Ive been using S3D for some time and I wanted to transfer my starting scripts to other slicers, mainly PrusaSlicer and Cura4. Here part of my start script: G28 G32 G0 X0 Y0 Z50 M109 S M190 S G0 Z30 ... Its hard to google somehow with keywords like "start script variables" etc, so has someone ever found a list or post, where all these variables like "extruder0_temperature" and "first_la

Looking 2nd hand smart effector for duet - 5 years ago

Hi, if youre giving up your machine and want to get rid of parts I would buy your duet smart effector. Cheers

Re: Change Delta lateral start position? - 5 years ago

That sounds to me like a thing to change in your slicer, just dont auto center your parts or change your center point in the slicer settings.

Re: Delta Motion Uneven - 5 years ago

How did you calibrate the endstops? Are you sure nothing changed? because that would be weird. Also do you plan on using any autocalibration? If however youre describing the koncave or konvex motion then your delta radius is probably the culprit.

Re: MMU2S on non prusa printers? - 5 years ago

found this which answers the whole topic quite well. Its hard to imagine all the details but from the way i imagine the colorchanging process, it should indeed be possible to treat the motors as extra axis that need no extra controller. and appearently there are already two projects that recreated the mechanism

MMU2S on non prusa printers? - 5 years ago

Hi, I recently ran into a MMU2 package on Aliexpress here that got me thinking if and how one could use that on non prusa printers. There seems to be no consensus if the custom control board would even integrate with a non prusa controller. If the controller is too special, controlling 3 extra motors and a filament sensor with an expansion board should be possible. Has someone ever tried this

Re: External auqarium airpump for hotend cooling? - 5 years ago

Has someone ever tried using a bigger blower fan to pump air through a hose? Common knowledge says that centrifugal fans have more pressure than axial fan, but how much more? its a bit hard to find pressure data for the cheap blower fans. but here it says ca 350 pa the berd air pump however says 80kpa thats one order of magnitude more...

Re: External auqarium airpump for hotend cooling? - 5 years ago

Quoteleadinglights A system such as the Mosquito may well work very well for most prints but may have problems if heat is finding other routes past the heatbreak. If the print and the filament need frequent retraction this may take more heat past the heatbreak area. Another source of excess heating will occur in heated enclosures and this will be aggravated if the filament has already been warmed

Re: External auqarium airpump for hotend cooling? - 5 years ago

Yeah i watched some more vids about the mosquito and it delivers with a small fan by default. What motivated you to build that setup? I dont see a heated chamber, or did you just notice that you dont need a fan?

Re: External auqarium airpump for hotend cooling? - 5 years ago

Check it out. I just saw toms video about the mosquito hotend. Ive seen that before on the bondtec site and kind of dismissed it, but here they explain the concept. At 4:50 they also mention that the heatbreak is now so thin that it appearantly doesnt require a heatsink fan. Im not 100% convinced because the heatsink is so small, but its an interesting concept. If this would work as advertised

Re: External auqarium airpump for hotend cooling? - 5 years ago

I see, yeah im still debating if control over the model cooling air stream is necessary, but having split air stream that can be closed by a small controllable valve is imaginable.

Re: External auqarium airpump for hotend cooling? - 5 years ago

Interesting so youre going to the model cooling first and the "rest" of the air is used for hotend cooling?

Re: External auqarium airpump for hotend cooling? - 5 years ago

That looks good and meets the specs that I was thinking about. Do you want to share a pic of you cooling setup?

Re: Current state of Y-splitter dual extrusion scripts? - 5 years ago

Well im thinking about getting a 2nd smart effector but 2 way mixing requires a new hotend and the e3d cyclops isnt cheap. although testing the concept with a china hotend will probably do. Also Im not sure if one still needs to feed both channels at the same time to avoid the hot filament escaping upwards into the 2nd channel. Needing a 2nd spool of filament of the same type just to feed 5% into

Current state of Y-splitter dual extrusion scripts? - 5 years ago

Hi, 2 years ago I got myself parts for dual extrusion with a y-splitter like this or this . The main issue with this system was that the pulling out the filament out of the hot nozzle would leave strings that would hinder feeding the material back in. This was mainly concerning PLA, I also tested ABS which had less stringing but wasn't perfect in that regard. There were some different approach

Re: Kossel not homing - 5 years ago

To state the obvious. Have you checked that the homing correctly set. Direction and homing travel distance? Also to check the firmware, just start with a clean marlin config and just modify the basic to fit your machine. That should give you an indication if its the firmware or not

EU Shops/ Wo kauft ihr? - 5 years ago

Hi, bei mir steht mal wieder eine Upgraderunde für meine Drucker an. Ich denke ich kenn für die meisten teile, einen vernünftigen Shop, aber was mir jetzt bei der Recherche aufgefallen ist, ist das man doch nicht drumherum kommt bei 2-3 Shops bestellen zu müssen. Openbuilds hat vieles, aber die US Versandkosten lohnen sich nur, wenn man komplett im Vslot System ist. Linear rails werden die ni

Re: Filament homeproduction fails due to lack of good spooling? - 5 years ago

Winder and Caliper wont work indeed. The tension the caliper would cause is too much. But I can imagine the hardware from the winder being used if the sensing mechanism is replaced by the caliper, and we add tensioning and a water bath. this guy tried it but the caliper wasnt suitable this guy has a pretty advanced setup but i havent figured out if he uses a feedback loop at all.
