I'm always interested in seeing your new attachments. I wish I had you skill and knowledge about this area...I'm more of an assembler than designer.

I am looking for a blade holder, something like the Aeronaut automation style. This looks like an easy and flexible system to change blades and sizes of blades.

I'm looking at options to replace my existing long rail system on my plotter. One option I've looked is using 8020 track with a glued belt and wheels.



If you look at approx 41 sec in you see the the 8020 track setup.

Any comments would be welcome

Is it a pen plotter you're talking about?? The 8020 rail in the video ought to be ok for that....but not for a router. I had a Shapeoko2 which was similar and had all kids of deflection issues with it.

Did you ever change your long makerslide rails? You had mention than you were looking at the Chinese SBR-20 linear slides.

Have you ever looked at the cam plugin extensions for the vector drawing program inkscape? Both have gcode tangential capability.

Good afternoon, wondering if this thread could be brought back to life. I need to make a drag knife plotter and I have access to a few here at the office. I work in the composite mast spar business and cutting carbon fiber is a day to day process. We have a 1.5mx1.2m bed here that runs a drag knife, will post picture of the blade and some more pics if people are still around. Looking for mor einfo on the maco/other methods to get the drag angle as a function of the x and y speeds.

I first thought was to use a high speed pulse counter to generate an angle based on the x/y counts pulse and generate a vector. Converting this vector will radial coordinate system will output an angle ...

Thoughts, as this will be retro fit to most machines as it listens in to the x and y pulse stream... will this work. as this will always be accurate as it is an instantaneous vector angle based on the pwm spacing between the x and y axis in the different directions.

thanks
Alex

Hi there guys , im new to the world of cnc . but have been interested for a very long time ,. i would also like to build a fabric cutter machine of approx 5ft6 wide x 10ft cutting area . where would i get any plans for one of these . i know i could build it if i had the plans and maybe a list of what i would need . the material i want to cut is pvc material same as whats on a bouncy castle bounce house . . im in the uk . thanks in advance .

I'm in the process or building my own plotter/cutter.

Another good over view of a router system with video's would be :

I am going to give the Add Corner Actions to your Tool Path - Donek ToolsDonek Tools a try, from their video it converts gcode to drag knife code for corners based on vector field... our xy table size is now the size of a household door, as this is flat, strong and from the hardware up the road. maker rail and grbl for control. Will have a pressure control for blade contact and stepper driver as a way to engage, stepper will lift beyond the safe contact point...will see what transpires.

I am also looking to build a cnc fabric cutter like this. I am new to cnc building so I plan to buy a gantry and rail kit. Then figure out how to get the fabric cutting tools. I already have a 16' x 66" steel table for a base.

The OP seems to have 16' continuous side rails. I cannot seem to source those materials. I also am having difficulty sourcing the pneumatic parts.

I have access to a shopbot and a 3d printer so I can make some parts as needed. I wish I knew which rails and gantry parts to buy. Should it be 80/20 or Hiwin or other rail?

Does it seem like a good idea to do a hybrid DIY, buying some of the parts and putting on a larger frame?

[twanna1994]

hey i am trying to build a similar machine but for cutting foam board for rc airplanes. Is there any way you could share your program for generating the Gcode for rotating the knife head? or is there a free software i could use to do this?

[amseam]

Look at either Sheetcam (https://www.sheetcam.com) or Cambam (CamBam CNC Software).

hello Pyronaught
it is my pleasure to meet you here,really I searched a lot to find such article ,you are smart man to do this machine in your own
please I need wiring schematic or detailed pictures for control box,
if you can send me links for electric components if possible,
my best regards

here is mine finally working! You were a big inspiration Pyro!

hello dear
would you please let me know more about controller box?

[raifdsgn]

may you declare more info about heat wheel design?

[raifdsgn]

but it is so quick ,how can we drive the machine with this speed??????????
