UP DLP LPC1769CD & Smoothieware

Post by pp3dp.se » Thu Mar 10, 2016 12:29 pm

So, finally got around to making the transition to Smoothieware and LPC1769, using a LPCXpresso board.

First task was to finish my old DLP project;)

I'll use this thread to document progress

Pictures on dropbox, as board quota seem to be reached

Take care all Uppers

Great to see this,

good to have a backup plan for the future in case the original hardware fails or if we got to it's limits.


Greetings,

What is the advantage of using smoothie?
The firmware is still marlin derivative or some new stuff?

Hi Jason

The codebase is not based of Marlin, there are parts of grbl although

Main reason of usage is that it's modular, i.e. you can use it for cnc/laser or what not and turn off the parts you dont need.

Example: just by adding a line in config, I got Smoothie to toggle a pin that turns on SD card, so that it works with UP mb, without changing in code

Other reason is that its the "most" stable opensource for 32bit ARM at this point, so it works with 1/128 microstepping without a glitch

Last reason for me, is that I can debug realtime and LPCxpresso 1769 is dirt cheap and from Sweden;)

Take care
