nanoDLP - Raspberry PI based Software for DLP Printers
August 21, 2015 08:20PM
Hi,

We have released first public version of our Raspberry Pi based software for DLP printers.

It runs on Raspberry pi 2 and does not require any extra hardware except strepper driver to handle printer.
It also provides web interface to monitor printing progress and etc

For more information visit nanoDLP website.

Any advice/suggestion would be appreciated.

Nice

zipped PNG as layers is and intersting choice, at full res even black and white.... suspect would be a resionabe size per object

Link description to download is wrong on site you show [www.nanodelp.com] but its [www.nanodlp.com] (extra e)
Link itself is fine.

Given that PNG is a compressed fromat, zipped PNG is a baffling choice.

Nice catch, Thank you

black/white png in fullhd size weigh around 3KB, antialiased one weigh around 40KB. Problem is that, uploading multiple png files is much harder than moving a zip or tar file around. Sometimes I use my cell phone to upload zip file from my mail client to the printer so it is convenient atleast for me.

A plate with 1000 layers usually weight around 5MB, I have not used zip to decrease size, But to have one file to deal with.
Current open implementations of slc to raw rgb image, which required to send to GPU, are too resource hungry to run on raspberry pi.
I hope to write one in near future.

I have added SLC support to nanoDLP, you do need to upload zipped png files anymore.

Hello Shahin
Could you please provide more details about which Trinamics boards or drivers does nanoDLP support?
thanks.

Hi Anil,

Currently nanoDLP supports serial/i2c/TTL signaling to communicate with 3rd party boards/drivers in both binary/ascii formats.
I know couple of guys who are using Trinamics with nanodlp.

Outside of Trinamics, as I know forks of grbl and marlin patched to support crash recovery and sync movement with nanoDLP.

Also nanoDLP capable of talking with command line tools so if your driver have command line tool, most probably you can use them together easily.

Looks like a great project. I had a similar idea a while back, seemed like the waste of a PC to use CW.

I have a couple questions about using command line for external motion drivers. I am looking to use an L6470 stepper driver which uses SPI.

Are there parameters sent to the command line, like number of steps or mm for instance?

Also any page showing how to configure command line for motion?

Thanks,
Chris

You can use nanodlp's internal help to get yourself familiar with commands.
Parameters could be sent as mm.
