Hi Andrew and Tom
I am back in the game, the machine is running again.
It was a stack of problems, started with the Xbox 360 plug-in; this one turned the machine in a mad man. Then there was the Idea, of the personality module, told to me from the man from the support desk of Rockwell Automation. And then I made a mistake with loading the wrong firmware into the Kflop, there are two directories DSP_kmotion and DSP_kflop they have both an .Out file. It was not clear for me which file I needed, so I did Recovery with DSP_Kmotion and new file with DSP_Kflop. Then I get these very strange messages in Mach3.
Now I have started from the beginning, and yes it is running as it was in December. The new plug-in works for the output from the spindle. The C progam what Tom wrote for me for the spindle did not work anymore, I started the spindle with the digital out screen from the Kanalog, and only the stop command was working in Mach3, very
strange.
Now we can use the in and outputs from Mach3, can I use these also for the -- limit/home switches? I hope so because these DynoMotion C-programs give me the creeps with their non predictable output.
I had gave the machine very small following errors, for 20mm, but when it is going nuts, it is going nuts what so ever.
Regards,
Cees

quite a lot of happy users - BUT - it is not perfect, the current project I have been working on has been a long project which started nearly three year ago, when I was contracted to write some software to control these machines. The company who contracted me specified that Mach3 must be the CNC engine behind the software, and so I did as they asked, but it was a major task, I found major problems with the macropump and with scripting in general within mach, and in the end I ended up rewritting the macropump (now controlled by my program and not mach3) so that I could get it to work properly.
