Dear Rodw,
This is the first prototype setup of the tangential plasma torch.
This is a very special technique, because the nozzle pad is always the same. If you have a robotic machine you nozzle pad is always different. So try to understand the benefit's of this tangential type of cutting.
All my prototype product's are starting like this. Make some simple connections, make some simple steel work. And look what can be better, My advise is : always design with standard parts. So cost's can be low.
This is based on a Hypertherm Duramax Robotic torch. It was about 500 Dollar and i demolished it. HIHI. Nice to do some reverse engineering.
Now i have made some update's to the housing and have to do it i think 3 times over to make a good one that is ready for consumption. I also added a second motor for automatic program 0-60 degrees of the plasma torch. Then you can switch during
cutting program to different angle's automaticly.
It is using a sheetcam tangential module for programming the dxf drawing automaticly.
In the postprocessor you have to do some work. After that is done and tested several times, it moves like you want.
It has a trick in speeding up the rotationg angle in G-code. Otherwise is moves to slowly in corners. Now it rotating like a helicopter during the g-gode process. Just what we want.
