Mockturtle,

I should have brents board in a few days. What I am hoping is that it’s not actually bricked beyond repair with a AVRISP programmer. That is my goal. Then we can work together to get you a fix for your board. However, if the board’s fuses are incorrect then I think it might be safe to assume you might have got a few of the “badly flashed” boards that went out. This is a new issue for us. Specifically the issue of HAVING a bootloader but not having the fuses set correctly. This is one of the guesses I have for the situation we find you and brent in. However it has never happened before. We have shipped WITHOUT bootloaders but never without the fuses set correctly AND having a bootloader.

I am hopeful that when I get the board it can be fixed without a programmer. However I cannot swear by this. Another option since you are in a different country is to reach out to a local hackerspace to see if they have an AVR available. I do not suggest this to shift the work onto you, but rather as a time saving option. Like you know it takes time to get a new board to South Africa. If I shipped it today you may not have it before the new year. However if this is the option that you would like to go please let me know and we can start that process.

Rest assured that we WILL get you up and running asap. We are very sorry for your issue with your TinyG board and are trying to fix you up!

Roberlin,

I imagine your vibration issue is really an EMI issue.   When you held your spindle did you also make it further away from your controller?

I have a Panther CNC PCB mill with a Chinese spindle.  The thing make a ton of EMI.  When I hook up a dremmel or a DeWalt trim router… NO problem.   A few things to try..  Can you power your computer + tinyg on a different circuit that the circuit your spindle is on?  Easy way to check this is to turn off the breaker that your computer is on… The go back and find a close circuit that is still hot.  Use that as a power outlet to drive the spindle.  Try that.

If that works cool.  If it does not there are a few things to try..

This is a really good article I found when dealing with this emi stuff.  Its worth a read.

Let me know how it goes.

So here is an updated video of tgFX drawing. Its VERY early still. It still has issues. Like so support for zooming / scaling (Meaning, this file was in MM and had a max travel range of say: 50 x 30 mm. But if you ran a file that was 5mm x 5mm (X and Y) then it would be very hard to see) and no ability to reset the view. Some other minor things too.

I am not exactly sure that I am drawing the “correct” JavaFX 2 way yet either. It seems like it should be more smooth.

GUI Update:

The tgFX initial VERY VERY alpha push has been committed to the synthetos github.
Code:
https://github.com/synthetos/tgFX

Its a netbeans project right now. It also requires the JavaFX2 runtime / sdk. It has ONLY been mildly tested on Windows as well. However it should work on Linux, OSX also.

If you are interested in helping on tgFX we welcome the help. Also, the .93 version of TinyG is a great improvement (for JSON support and LOTS of other stuff) much has changed. So this GUI will not work with your current version of TinyG (.92). Alden was going to be releasing a the .93 version today however he hit a few minor bugs he wants to fix first. I can get the BETA firmware out if you are interested in helping with coding tgFX.

The best way to get started working together on this is to join the Google group:
http://groups.google.com/group/devTinyG

From here we can start to formalize requirements, feature requests, architecture etc.
