Teacup laser on a Yun
May 13, 2015 11:56PM
I was wondering if there is anyone that has a simple xy laser setup wtih teacup and what solution do they use to fire the laser and set power. I have a Yun I want to try to use. Also any links to the laser part of teacup would be great. I dont need any temp monitoring or any other axis or hotends beds etc. so hopefully it can get gutted.

I was hoping to run the Yun straight to a set of Geckodrives and 2 wires to the laser that would pretty much be it no shield needed? I may use a few cheap drivers to mess around at first.

Also any tricks I may be able to do with a Yun and the webserver/linux part?

So far I think I needabout 12 pins:

2 step pins
2 dir pins
2 enable pins
2 endstop pins
2 communication pins (maybe not needed with Yun wifi etc?)
1 pin for pmw laser power
1 pin for laser on off

To ignore the temp input in Teacup you simply remove this sensor in Configtool. Then you control the "heater" with M106 S0 ... M106 S255.

You also have to create a dummy Z and E axis (can be the same I/O pin, no endstops needed). Support for an arbitrary number of axes is only partially done so far.
