fabconv,
I spoke with Stefano Duranti (Profili) and his software won't support this type of machine, but it does look good for a 4-axis wing cutter though! I am not sure about GFMC, as far as i...

49 views and not one reply, not even an opinion? This forum is very opinion adverse compared to the other forums I post on for my airplane design... Usually someone is quick to shoot down the idea...

Here's a concept of where I am trying to go with my 4-axis system. I want to cut conical fuselage cores, and highly tapered wings. This is where the variable wire length comes in, when the cone...

Hi Zenock,
What is the solution you are implying with that last sentence? My current plans are still a 4-axis system, with a wire extension mechanism (Probably pulley system and hanging weights...

Hi folks,
I am designing a CNC hotwire cutter for wing and fusealge cutting. I recently came across an interesting issue, I don't see any CAM software for a 2 Axis machine with a turn table to...

Hi Folks,
I have an interesting problem to solve, and I am not sure how to do it. I am building a large Foam Hotwire, ~7' X and 4.5' Y travel with about 6' wide wire length when both wire trucks...

Hi Folks,
I am wondering if anyone would be willing to describe the coordinate systems involved with cutting a foam shape with a 4-axis machine. Does anyone understand how the physical location...

Matthias,
Thank you for the comments! That's a really neat project! how big is your cutter going to be? I just found some really nice angle irons I'm going to make into brackets. I have gone...

Harold,
Thank you very much for your generous constructive criticism : ). I am glad you brought up the stiffness point. Maybe if I switch to 2 steel angle irons for the rails or 2X4 steel box...

Hi Folks,
I am an engineer working on my own design for a CNC hotwire machine for my own use. I have been talking to a couple of people in my area about their hotwire and router machines and have...

Hey Folks,
For those of you who have experience building these neat machines, is there anything that you built that you wish could be made adjustable for tuning/de-bugging purposes that was not? ...

Mark,
Thank you very much for the input! So, 200 in-Oz motors would be the max I need? I think that's the size I am seeing in the industrial sized outfits (hotwire direct). I will probably do...

Hi Folks,
This is my first post, and I am very new to the CNC environment. I am excited to start planning and building my foam wire cutter. My ultimate goal is to develop a cutter for a full...
