Re: nanoDLP - Raspberry Pi DLP Host Software

Hi Ray, Android76 is right, you need to enter distance travelled per turn. http://reprap.org/wiki/Threaded_rod#Leadscrew About speed variation, as the pulses generated by CPU, OS and GC usually interfere in program execution, so specially in high speed, some non-even steps is normal. Make sure you h...

Re: Raspberry PI Based DLP Printer

Hello Shanin, I've build an DLP Top Down Printer powered by an Raspberry Pi and the Adafruit Stepper HAT driver. This driver runs over I2C using a PWM driver chip. Via the Adafruit site I've added the python and git library and installed Python. The test functions from the site works very well. But...

Re: nanoDLP - Raspberry Pi DLP Host Software

Any reason this wouldn't work on a Raspi B/B+? 1. Performance, Specially SLC to PNG module is really cpu intensive. And it would not play nice with RPi 1. 2. With multithread application design we have experienced slow down on rpi 1 which is non existence on rpi 2. 3. We have moved all of our print...

After further performance improvements I am going to add it to nanoDLP in form of native SLC support. http://www.buildyourownsla....
