The plans he sent were hard to understand.

Doesn't give a lot of info out on his machines. Need to get a post processor made by Bobcad to recognise Camcut machine. I went to the USA for holidays back in early August and went to see the guy at Camcut. He is only a 1 man band and he was very 'stand-offish' towards me.

He also had someone else there when I turned up(he didn't think someone would travel 26000 kilometres to see him). Hopefully that will give you a bit more info. Well.first thing I would do is to jumper the input start on the Powermax45 (you said you were using a machine torch, not a hand torch).this is done on pins 3 and 4 of the CPC interface connector on the rear panel of the PMX45.

If power and air are on and correct.and consumables are in the torch it should fire. If it fires.next step is to trace whatever wiring or cable that is connected to the CPC port.to where it is connected on your breakout board. Jumper the same signal there at its connections.the torch should fire.

The next step, assuming the torch fires in both instances above is with determining why the output relay of your breakout board is not activating the start signal the same way that jumpering is doing. If the system is designed to use on Windows 98.that could be your issue *using Windows 7) You have a conglomeration of different softwares and hardware that may or may not be compatible. Can you find anyone that has the exact same setup that you have? Maybe CamCut can direct you to another user that is successfully operating their machine? Without some sort of help from the suppliers of your softwareand hardware.you will likely be out of luck. Mtw fdu wrote:Plasma cutter is a Hypertherm Powermax 45. I am using Mach 3 for the software as well. I have just been told by my cnc guy that the relay on output 1 has to be connected to the MOV.wherever that is.
