Re: Using a BeagleBone Black

It appeared to me when I looked at it, that the easiest approach to this would have been to use a pcduino3 and a voltage translation board which would directly permit plugging in the gshield. I didn't go any farther with it, because adding in the real-time kernel changes is non-trivial. There are ex...

Re: Using a BeagleBone Black

I've not seen anything specifically for PCBs, but it's purpose is to generate gcode from your CAD tool, and I always assumed that the CAD tools would be what would be specific to PCBs. Honestly, I am not versed in PCB generation so I can't say (nor recognize for that matter) what specificity a CAM p...

Re: Using a BeagleBone Black

Yes, that is the application I was talking about. It should run on any Linux system. It's unfortunate I couldn't use the 7 inch because I also bought a touch screen overlay for it. That would have been very handy onsite at the mill. Since I couldn't, I bought one of those cheap little keyboard mouse...

Re: Shapeoko 2 Project, first of two

I thought I should update this. The noise circuit worked perfectly. Using it, I was able to make the mill home correctly and not fail constantly with false noise trips. I am considering cutting the 1000x1000 size of this mill down now since it's Z-axis is too flimsy (as expected) to do anything with...

Re: Using a BeagleBone Black

Thanks very much for the input. I would agree that having a custom script purpose built would be superior to the stream.py I was using. What I ended up using was Zapmaker's QT application (which should work on any ARM or sunxi linux platform). It only works if you have a sufficient sized screen. The...

Re: Shapeoko 2 Project, first of two

I made up the embedded limit switch noise board today. This circuit is the one cvoinescu provide for a normally closed configuration. I soldered it up on the screwshield placed between the Arduino and the Gshield. I also bought a couple of sets of shield standoffs to raise it up so I'd have some roo...

Re: Limit Switch Wiring?

I just ripped out my switches because they are getting too many false trips and I'm rewiring everything again. But, before I did, I saw your post and measured voltage downstream of the capacitor to the limit switch pins on the arduino. I had 5 volts, so your 4.96 doesn' t sound like a problem. Mine ...

Re: Shapeoko 2 Project, first of two

Today I spent my time trying to run and set up a real job. I was going to try it first on wood. Using GrblController, I kept hanging up for long periods of time. I finally decided to do the entire process in Python miniterm so I could see what was happening. My friend the false limit switch tripping...

Re: Shapeoko 2 Project, first of two

Thought I'd provide a blow by on the last weeks activity. It has been quite slow. I've worked steadily on the mill but made very little progress. The limit switches have not given me any false trips since separating the cables from the wire bundles. Software has still been a significant problem. The...

Re: Shapeoko 2 Project, first of two

Update on limit switches, homing and gcode. (Edit: I've done some testing with this method below. It doesn't work. I can't place the stock with enough accuracy to do it this way. I should have realized this, Indeed, I'm going to have to communicate with the program during set up to tweak the startin...
