EMC2 Lockup in MDI and "Zero All" Killer

I have two questions.
Recently installed ECM2 V2.4 and Ubuntu 10.4 Never used any ECM or Linux before this.

1) Please help be understand why the Zero ALL would wipe out all number is the Cordinate System Variables (not just the one you are on, but all of them!!!) e.g G55, G56, G57, etc.

Zero all is a great tool to zero out all the axis's. But why in the heck would it zero out all of the saved cordinates !!!. That is just way weird. I went through a lot of work to put in all of my work offsets, only to have the students' wipe'em all out by hitting Zero All when trying to jog. Any way to disable this particular icon?

2) I have had my system lock up several times while in MDI. You type a command in, and it does nothing. This is when I am in a cord. shift of G56. Then you have to quite ECM2 and start all over to find home again (because I was in G56 and not actual zero). My machines do not have homing switches so I have to find everything manually.

Thanks.

The front end is called TKMini. It came in a bundle from Sherline.

I assumed that it was all set up and ready to go. I did not know about the latency test.

I am a bit confused I guess. Doesn't EMC2 come with TKMini? If not, then do I have other choices?

I went to the about screen and got you that information

But when I look at the links it is the one called MINI.

I am not sure what version of EMC2 it is. I tried to find the version number and could not locate it.

I know Sherline packaged it with 10.04 so I think it is the 2.4.4 version.

I won't be back there till Monday. I will report back in with the the version number (If i can find it).

How do I go about getting Axis?

I changed the display to AXIS.

I now get an error something about usr/bin/axis.

I want to download the most current version of this Axis program, but have been unable to find actually find it on google.

I do have EMC2 version 2.4.4 just downloaded the 2.4.7 release and trying to figure out how to install it from that tar file.
