Yes, it is finished and working very well.

Hello Stephen,
Did you finished your toaster oven reflow controller project ?
I would like to build a DIY refusion oven
Thanks for any comments/updates
Regards,
JC

Hi! Where can I get the schematic of this project?
Best regards!

Comment on The road to 3D Printing, part 4 by Stephen

Not yet sure if I’m going to implement microstepping; but it’s a possibility. I’ve so far been just trying to get the core functionality put together (which, now, it pretty much is)
I will probably experiment with making it autonomous at some point, there’s an onboard SPI flash that has a lot of space free; however the board was designed to be a good friend to a PC :)

Nice setup (https://picasaweb.google.com/114257244810512271993/3dMf70#5713208861615163394) – I like the SD card interface :P
My fpga is I think a few orders of magnitude smaller than yours though – it’s currently implementing a minimal (pure vhdl) motor control queue, so all the acceleration/etc is to be done in the host currently. I am planning to switch to a bigger FPGA though, and will consider a more complicated hardware implementation then.

Are you going to do a microstepping and SD-card interface?

3d printing of big parts takes a loooong time so autonomous printing is really usefull :))

You can look at my project at github:

https://github.com/sevikkk/VP2motion

It’s fpga based motion controller for my reprap-like 3d printer.

I’m using .s3g files for makerbot printers as intermediate format. I do simple acceleration in hardware and path planning and synchronized acceleration profiles in postprocessor after slicing.

This looks like a lot of fun and a great project! PS, your our only hope for DSTunnel! So close!

Hi,
My name is Pawel and Iv been into electronics for about 18 years now. I use fiber glass prototype boards but would like to start etching and designing my own. I really like your video and would like to ask you what software do you recommend to learn on?? and what is the one you are using.

Thanx Pawel C.

[...] let me tell you about JTAG. I made a post on jtag a long time ago, when I was first starting to mess with it; but for this project I decided to build [...]

Comment on CNC Controller by Stephen

The board is designed to work with either USB or serial; The hardware is sufficiently flexible that the specific design could work a lot of ways – at the moment I am planning to write a gcode parser that will run on the board itself, so the host will just send gcode to the board.
There will be seperate utilities for setting up the motor mappings & knowledge of speed & etc.

design looks very good:) would have a few questions to me if you can split the time.
I wonder if the communication between the program and the CNC control card.
That is what the task at work in the CNC control unit?
How does the program from a command?
In the form of the G-code?
Is the program undertakes all the work?
How does knowledge of the servo speed and acceleration?
specifically, about the functioning of the card, the flow diagram, please share with us
Thank you for your assistance.
