I am working on a DLP based 3D printer. I already sliced my STL file to multiple layers. Each layer is saved as a SVG file. Because its an SVG file, I can always convert each layer to PNG/JPG file if desired.
I have a TI DLP Lightcrafter 4500 module connected to my laptop using the HDMI. The DLP shows up as a second monitor on my laptop. I am using LabVIEW to control all components of the printer.
Question 1: How I can programmatically display my desired image file on the DLP projector. I would prefer to use Python or LabVIEW to display my desired image onto the entire screen of the DLP. Is there any way to achieve this on Windows? I also have the option of using Raspberry Pi + LabVIEW using LINX (http://www.labviewmakerhub.com/). I looked at nanoDLP (http://www.nanodlp.com/), which is a control software for DLP based 3D printers. However, I can't figure out how they manage to display the desired images to the DLP.
Question 2: Is it possible to display a SVG file to the DLP instead of PNG/JPG/BMP? If not, how do I know which resolution to use when converting SVG to PNG/JPG/BMP?
Q1: Printrun is 3D printer host software written in Python with limited DLP support. You can checkout how it display layers. NanoDLP directly talk to GPU through Dispmanx which makes it Raspberry Pi only.
Q2: Printrun supports SVG. To convert SVG (multi-layer) to PNG you can use ImageMagick cli tools, you should consider your projector resolution too.
12V/24V Perfect for Prusa i3 3D Printer. Note: this is not a shopping question, I am merely providing a background to my questions. While the RepRap wiki is full of information, the information can.... I am keen to buy an aluminium PCB heatbed for my P3Steel v.4 printer, which has a larger build area of 200 mm x 300 mm. So, after some searching, I found this MK2A: MK2A 300x200mm Aluminum Heated... not sure if this should be a separate question) I would have also asked whether aluminium PCB heatbeds are worth the additional cost, over standard PCB heatbeds, but for the slightly less common
I'm popping my cherry here, so to speak.

Although FDM is certainly a realistic "no-brainer" capability for this setup, I... to concentrate on. With such a large printing surface/volume (37"X x 24"Y x 28"Z), I don't know how I would implement a DLP projector to cover such a large surface and still maintain the level
of the layers so I think it must have something to do with slicing settings, but I'm at a loss for what I need to change to fix it. See below for images of the issue. On the orange piece near the right hand side you can see light shining through the gap. The black cube has it at the top, though it's not deep enough to let light through like with the orange one. There is also an image of the layer preview which shows the same gap. I have a Rostock Max v2 (stock hot end). I am using Matter control using mostly stock settings, I've tweaked around layer height, speed, and temp but I don't think those
in step per second per step instead of step per second per second, and is therefore increased exponentially instead of linear. I have found this article that explains in mathematical terms how one can achieve a linear increase with a stepper motor but I have not managed to translate that into my python code. I would highly appreciate it if someone could help me with this and I think it would be very useful for people using steppers on the Raspberry Pi in general (I have only found a solution for the Arduino here Thank you very much in advance.
I have bought myself an I3 3D printer - it comes with a thermistor which is then placed into a hole in the hotend and held in place by a grub screw. Sadly due to my lack of care I managed to crush the wires with a pair of vice pliers whilst trying to remove the nozzle as it was clogged. I have since unblocked it but now every time I turn on the 3D printer instead of giving a minimum... amplifier board (the one that Marlin supports, I forget the name)? The thermocouple I have in mind is one that has the junction exposed (see image below), does this matter? I plan to re-route

I returned my 3D printer controller board since it died, after only doing a dozen failed/successful prints. I have bought myself a RADDS board which set me back £72 including motor drivers but not the Arduino Due. Will I see some real benefit in upgrading to 32 bit because surely it doesn't make it print faster?
. Where would you get these cells from and how would you be able to go from using a 3D printer to layer these cells together to then forming an organ out of that? ...I've heard of 3D printed ears, limbs, and muscles. I assume if you were to attach one of these ears to a person, it wouldn't have a sense of touch and other properties that a real ear would have. So which properties of real human parts does 3D printing allow and which properties is 3D printing not capable of reproducing using current technology. And how do you predict those technologies
