Very interested tom1jae to see those pictures. Mind posting the link to your self adhesive sheet metal source?

Re: Limit switches & auto tool height setter?

on my touch probe I backed it with a bit of 2mm adhesive craft foam on a pcb. So it has a little spring to prevent blunting.

Re: TinyG Fan Control

Going up in size would work well. But i'm not excited about cutting out a new case. But agreed I am running my 40 mm to hard. I'm thinking i'm going to put in a voltage divider and just run it at 6-8 volts.

Anyone else use SketchUcam in their workflow?

I came across a nice plugin for SketchUp called SketchUcam. It's actually a really nice CAM plugin. Allows for pockets, inside, outside, center line cutting, tabs, etc, and even will do 3d tool paths, and progressives paths. It's a little confusing to figure out, but once down it seems like it's all...

Re: Limit Switch Debugging.

Thanks! Yesterday I spent the day tweaking my setup, and discovered that it was a windows driver issue! I was using an out of date FTDI driver, and while the board looked like it was getting chars, something was going wrong windows side (no surprise there) and that coupled with a loose stepper motor...

Limit Switch Debugging.

What's the recommended way to test my limit switches on my tiny G. I have 4 installed right now for the min & max for my X & Y. I wired them as NC, ground to the ground pin, and other side to the min, max pins, etc... I used cat 5e for the wiring from the limit switch to the Tiny G. I disabled the Z...

Re: TinyG Fan Control

Thanks Alden, I have read through those wiki entries. I'm actually powering NEMA 23's with it. And my fan is about as small as they come. it's just a 40mm fan. I mean I could put in a 24 volt fan and run it off the 12 volts, or just use the 12 volt fan with a voltage divider, resistor, etc... But I ...

TinyG Fan Control

So I have my Tiny G in a custom laser cut enclosure I built for it. And I covered all the stepper drivers, and the atmega processor with AL heatsinks. I'm using a 12 volt 40mm fan to cool it, and I notice it's a 3 pin fan port. Yet my fan just seems to run at 100% the entire time. Is there no variab...

Re: MakerSlide or Open Rail for Steel Wheels.

Ah, indeed that 120 degree angle would indeed be no good. I was fooled by the pictured specs on ebay. Which did not state the angle. Just looked like a 90. Should have been more skeptical I suppose.
