Looking for noob guidance on laser rastering (Ben's work)
Posted: Wed Dec 12, 2012 3:26 pm
I've been successfully running my DIY laser as a simple vector cutter using Mach3, but now I'm becoming aware that I need more precise control over the laser power, and rastering is proving to be difficult.
So I installed LinuxCNC (Ubuntu 10.4) and managed to get control of the laser as before.
So now I'm looking for where to go next...
I've been reading through Ben's posting on his Laser work, and the readme here : https://github.com/bjj/2x_laser/blob/master/README.md
It looks like I need to do the following things:
1. Download the build essentials for LinuxCNC
2. Grab the HAL code and build it
3. Install the HAL into LinuxCNC (is it a problem that Ben is using EMC2?)
4. Grab the "other" code/scripts and somehow build and install them.
I got a reasonable rating on my system latency by applying various tips and tricks online - I have under 30000 as the max value (not excellent, but good enough)
I am however a bit lost trying to understand exactly how latency will effect my max speed and travel while rastering.
Any assistance would be greatly appreciated.
Thanks in advance,
Steve
