Any using Foamwork software?

The cost of the chips and having to purchase 25 of them makes any of the other boards very reasonable. This is why I went with the Hobbycnc board. Those prices are just gouging for a do it yourself type when it is a hobby.

I have actually found them this week for 9.95 a pop, which is almost back to the original price I paid two years ago. They had 450 on hand and I may just pop for 25 or so just to have some on hand for later projects. Although the 3979 or 3977 would work well too. just dont feel like redesigning the board as of present.

I still like the unipolar steppers, but am going to work on a new setup with bipolars in the near future.

venomx,
I've been cutting airplanes for 2 years with Foamworks exclusively.
As mentioned go to the site and download the free trial programs.
At a point I had a video out showing going from autocad to cadwords to foamworks.
In short you need to set the order of the lines.
They are not set that is why you got zig zag.

Load dxf file into foamworks
make a new blue layer
trace the dxf file counter clockwise starting from the right
working your way down covering any horizontal positions.
and exit on either side

Theres a few hurdles:
Sometimes in foamworks you can't get the dat file to go down to 0
A few methods resolve this fairly quickly
Knowing which way to trace something so that gravity doesnt have a bad effect on cut accuracy (from parts settling that get cut again)
Shapes can be setup to autotrace in foamworks which takes the tracing process out of it! (it requires that no lines over lap though)

Videos will be posted showing the whole foam cutting process.
I'm working on a second cutter now and need help on wire order for the motors which will be posted too.

Just ask any questions you have and the video will make sure to cover it.

I have had a issue with sweeps on wings, do you think you can help?

Thanks,

Chris

does anybody as a detail of foamwork pin port for hobbycnc rev.0 foam cutter . i would like to try since 2005 and still stuck .. not cut yet. i use 3/8 16tpi rod.
i will try different software if i can make work right , i try emc2 and not luck .
thx for any help .

I have tested demo version and it works ok. Only problem is that FW only give you 1000 step/sec. That can limit cutting too slow if using low pitch screw.

hi, do you use hobbycnc board to test foamworks, if yes what setting did you use to controll the bard .. can you take some picture of the setup. i can't get it right pin port setup or the motor speed ???

I have not used my foamcutter for a couple of years but will dig up some of the info later. My cutter is also 3/8 x 16tpi and the steps for running foamworks from my pc is 3217 steps.
Hope this helps.

Any tricks in Foamworks or cadworks on getting the line segment equal between to DXF files?

I can import a wing root DXF and Wing tip DXF, but when I prep the drawing it ends up with two different line counts. I have manually traced over the drawings, but it is time consuming to draw 160 line segments. Also the cut is not very even because I’m guessing at where the points on the lines are as I trace in cadworks.

An option to split a DXF in the drawing prep to a specific number would be great.
