Valkyrie

Phoenix Rising

Hi all!

A new year, a new reboot.

Valkyrie is officially dead, buried, gone ... RIP Valkyrie. 

She did her job, teaching me a lot of stuff about mechanics, electronics, programming and building stuff in general. 

Probably the most important thing I learned is to take your time doing stuff, because finishing fast does not always mean you finished good, sometimes you end up with a really crappy part and all work was in vane. Starting with  2011 I'll take the time to do it right, no mater how long it takes, if the end result counts.  

V4 Stepper Driver

Hi LMR!

It's been a loooong time into WIP but it is finally there:

(Yeah scaling is bad, see the link down below for the Eagle files)

So what is in the picture above? I'll answer that for ya ...

Cuts 2D and 2.5D shapes controlled by the PC.
Hi all! V2.5 is almost here, I'm still thinking on a nice name for it :) For now a list of changes I have done since V2.1: - upgraded motors to 200 steps/rev bigger … Read more

Reboot

Hi all,

In the last three weeks, and especially the last week, I've been working on V3, trying to finish it.

Oh well ... it will not happen because:

- it is a very large project and it consists of a very large number of parts

- everything that could have gone wrong ... got wrong

- I'm running out of time

- cutting parts using the V2 in an apartment is just crazy, I had enough of the noise and more so of the dust

- killed all my endmills

- almost destroyed the V2 forcing it to go faster

V3 - Borg it is!

Hi all!

Here is quick rendering on how V3 will lokk like :) Almost finished the design, still little things to take care of, I can start cutting soon.

 

Has a Borg feeling to it :D 

 


Update - Z-axis

PCB milling

Hi,

I finally got an usable result trying to mill PCB with my machine. 

I tested using this Eagle PCB layout:

I then generated g-code out of it using the pcb-gcode eagle plugin with the settings below:
