Z-ram size

[Michael Johnston]

Hi everybody! A former co-worker changed the size of the Z-axis RAM in PC-DMIS because we have an older LK that has a substantially larger RAM than our B&S Global. Anyway, somehow he found the file and was able to change it but I have no idea where he found it or what it's called. It's a real pain trying to program with it offline and run a collision detection on it. The older LK will never run PC-Dmis. It will always run Valysis so I don't need to worry about any programs being ran on that machine. If you have any ideas please let me know. Thanks in advance!

Can you upload the machine definition being loaded? Comparing it to a virgin copy might tell if a reference can be changed. What size did you want the spindle to be?

[Michael Johnston]

I'm not sure of the size of the spindle but I could get a quick measurement real quick. Whatever the standard spindle size is for a Global Advantage. The LK spindle is huge and for some reason it is the "default" when programming offline so it's a real pain in the **** when programming in tight spots.

Have you tried loading a different machine? You might be able to find one close enough to what you're looking for.

In my case the CMM model wasn't available and our Global has a slightly larger spindle than the closest model installed with PcDmis. I am mostly concerned with spindle crashes so just modified the head adapter to simulate the spindle. The below is enough to show the "footprint" in a plan view. Sometimes I'll lengthen the extension if I'm going into something deep. (notice the Z values are 0 or negative). This is from my usrprobe.dat file - basically just added a flattened cube on top of the stock adapter definition I copied from probe.dat.

You might be able to get away with something like the above. Surfaces have no thickness so it shouldn't affect probe lengths. A benefit to going this route is not receiving "out of travel" errors although you may prefer the notification.

Having the carriage legs would be nice for when I mirror a part and end up with different probe angles (just have to be careful).

If you just want to get the standard machine(s) back, yours and all the others, you can just take a copy of the MACHINE.DAT file that comes installed with PC-DMIS. You can get a copy from anyone, they are all the same, assuming that person did not also modify theirs. This is found (and kept) in the same folder where PC-DMIS is installed.
