I have already asked multiple times. What is the magic to update the firmware?

The AVRdude instructions in the wiki are either wrong or incomplete. I have done it many times and every time it crashes in an error with no error log.

I have updated firmware on many microcontrollers. It shouldn’t be this hard.

UPDATE: I just added a wiki page that begins to document where to find the firmware, and I added a link to it on the main page. It amazes me that something so pivotal is not documented already.

Here is what I said in the other thread about my attempts to upgrade the firmware:

The stuttering bug has reared its head again, and TinyG damaged an expensive hunk of nylon. I’ve tried for the past two hours to figure out how to update the firmware, but I hit several roadblocks.

First, you suggest using AVRdude that came with Arduino. I have Arduino, but no AVRdude. I can see the TinyG in the Arduino serial window. I can trigger boot mode by issuing $boot=1 from inside Arduino. But no idea how to use it to update the firmware.

I installed AVRdude. After some path variable issues, and figuring out that I have to issue $boot=1 in CoolTerm, then immediately close it and issue the AVRdude command. But it crashes during the loading process. Ends in Failed, Failed, Failed a thousand times so that any useful info flies off the screen. And the logfile switch doesn’t work. If I redirect the STDERR to a file, it contains nothing. Frustrating.

Which firmware? I went here:

https://github.com/synthetos/TinyG/wiki/TinyG-Boot-Loader

It lists this link:

https://raw.github.com/synthetos/TinyG/master/firmware/tinyg/default/tinyg.hex

If that’s not the right one, which one should I use, and where is it?

Sure. Meant to do that last night.

> I can’t get my machine to run without it missing steps every once and a while which causes a serious “oops” and trashes what I’m doing.

How does that fit with the TinyG page, which claims “Affordable Industrial Grade Motion Control?”

What kind of business can afford to repeatedly wreck hundreds of dollars of raw materials because the CNC board decides to freak out.

I apologize for the inflammatory (although factual) language of my post above. I returned here this morning to delete it, but cannot.

My TinyG destroyed a large, expensive hunk of polymer, and I’m frustrated.

Well, okay.

Then for example, how would I lay down a uniform extruder bead if the speed isn’t constant? I’d have to extrude less while the machine was coming up to speed, and extrude more when it was moving fastest.

If my jerk setting is too low, is there a video that shows what the motion should look like? Or does that depend on the mass of the moving part?

How would I know when I have the jerk setting right?
