I manage and maintain all the injection molding articles in my company (More than 200.000 pieces a year come in)
And also design new ones now and then.
So I do allot of rapid prototyping. Sometimes my printer is on 24/7 for a whole month in a row.

Check your bed leveling and distance to the nozzle with the a4 paper technique.

Does it still extrude properly if you run it manually above the bed?

It looks like your layer height is too high just above the holes.

i'm glad you can have access to any piece of cad software you like, however for the good percentage of us this isn't an option , does that mean because i cannot afford a copy of say solidworks or inventor i am not serious about the opensource philosophy? don't get me wrong i would love a copy of either of them i just can't afford it.
OK let me rephrase that

I don't use end stops or homing switches at all, you do have to watch the z-axis as to not crash the nozzle into the bed, but have had no real issues without them at all.
Running Mach3 with a TB6560 controller, no homing gcode.
So how did you do the initial calibration? And what do you do when you move the head manually?

Since 3d printers using stepper motors always print relative to their origin, yes you definetly need them. You need to reset the origin every time you start a new print so that it keeps printing in the right area. Almost no printers use absulute servo motors so your computer has no way of knowing where the extruder or the bed is inside the machine if not for the origin at the end stops.

Just make some ABS slurry and apply that to the bed:
I run my bed at 65C and apply the slurry with a spatula on top of a printing sticker. (Tape should work too). Prints have never come of since I started using this slurry.
Ive heard glue sticks and hairspray work as well.

I have a bit of experience with AD from the 3D graphics pov. I work for the main competitor of AD in Europe.
In this area AD frustrated a lot of customers by either buying up competitors (Softimage) and dropping the product, or by simply not doing any serious development for their own product (3dsmax) due to having a safe sales position.
Either way AD customers on the 3D DCC market are

Hi,
I'm new to 3d printing. I'm in the process of researching my first printer, how they work, the capabilities and limitations of 3d printers. I do, however have 12 years of manufacturing experience with plastic extrusion and injection moulding. Maybe this has given me and insight or maybe this has been discussed before?

Good to see them jump into this.
The more big names in engineering get involved in this the better.

Try a different slicing software. Especially Simplify3d that you can buy from their site has some problems. (But is good overall)

I use it for rapid prototypes. We make fruit and vegetable sorting machines and there are alot of injection moulding parts which need to be prototyped and tested before we buy a 50K mould.
Our 2000$ leapfrog Creatr really helps with that. The ABS rapid prototypes I make, are even sturdy enough to run on a machine for a few days.
Its especially usefull when prototyping cups for transporting f

The fumes of PLA are harmless, while ABS fumes have a high small particle count. (Not higher than living in a big city).
If you keep it in a ventilated room, you will have no problems. Do mind that research is still being done about this.
Also you wont see 3d printable electonics that are usuable in a 3d printer. (Steppers and microchips) anytime soon. (Tough I do think it will eventually be don

Align one xtruder close to the bed using the paper method. Then loosen the second extruder and pull it down a bit.
Place a piece of paper under it and home the Z axis. The table will push the extruder into the right position after which you can fasten it.

Right, so now we're talking about the same features, one which is as you say provided by a free tool and one that costs real money. Given that this is the RepRap forum and not the "I spent $10,000 on a commercial printer because I could" forum you can probably understand why we like the free stuff...
Put another way, why would I spend all that money on a commercial tool to do

Nophead's excellent Mendel90 is modelled entirely in OpenSCAD. The benefit of doing this is that if we want to scale the model then all we have to provide it are the dimensions of a few basic components - the heated bed, the motors being used, the diameters of the steel rods, etc. The ENTIRE model is then redrawn with the correct dimensions, holes, etc, plus it produces a bill

Can you extrude filament using the extruder when its hanging above the table?

3d printing ABS already gets soft at around 110-150C and gets extruded at 200-250C.
The reccomended Temperature range for normal ABS is from -35 to +85C
If it comes into contact with temperatures higher than that you are in trouble.

Hi,
for school i need to make a -so called masterwork-. I has made a XYZ mill with on each axis a stepper. All of the components are perfectly working. My machine is made to put on a wall off a house an ''mill out'' the egdes (if there are to old or ugly) between the different bricks. So i made a picture of the wall, use some matlab algoritms to calclute the midlle of the edge. Now

Beste,
ik heb een vraagje ivm hoe ik g code kan genereren uit een ander bestandstype. Ik weet dat dit gaat me .stl of .dxf maar bij mij ligt het probleem anders.
Voor mijn thesis maak ik een freesmachine die voegen uit een muur moet frezen aan de hand van een genomen foto. Deze foto heb ik bewerkt met allerlei algoritmes om zo het midden van de voeg te vinden. Nu heb ik het midden

I am new to this and wanted to try out if i can manage the software before i get my printer.
i worked with sketchup and a lot of 3d map editors for games before.
i do not want to spend too much on the software, so
can you recommend something for me?
openSCAD is a bit too much "type in what you want"ish for me
is there any GUI Oriented (maybe free) 3D Software out there,

Is your nozzle hot enough? Try increasing the temp a bit, the temperature that your sensor is measuring isnt always the same as the actual nozle temperature.

Retraction, retracts the filament a bit when the nozzle is moving to a new point. This prevents strings and irregularity's.
Look for it in yous slicer settings. (I dont use Sl3cer myself so I would know where to look.)

Yeah its quite cool you can to that.
But its not unique to that cad program.
So its like adding a few planes x distance appart and parallel to eachother in a 3d model.Then importing DXF's onto each plane as a sketch. And then extruding each sketch from each plane.?

I dont know, you can do that easily in just about any CAD program.
Same with importing and exporting DXF files.

I posted both topics yesterday. Ive never even heard of openScad a week ago.
I posted this reply here in this thread and then tought to myself that I dont understand why people use openScad. Hence me opening that topic.
