General Mach Discussion / z direction

« on: August 14, 2011, 06:32:06 AM »

I know this sound so basic as to be laughable, but do you set up z axis as plus is downwards or plus is up.
I ask because I had z set as plus down, using the write wizard, but now im using lazycam for the first time, its seems to set things up as z plus up.

also I have x and y as 0,0 in the top left corner in plan, is this right.

Maybe i'm missing something, as Im only just getting started.

sorry to introduce such basic questions

General Mach Discussion / mach 3 stops responding

« on: August 08, 2011, 04:50:37 PM »

I'm still trying to get past basics, but seems to run into a reoccuring problem
After stopping a program, Mach 3 seems to lock me out, but z axis starts to rise very slowly, and I cannot stop it, except by e stop.
I get error message  - Abnormal condition IJ mode is absolute.
The only way I can get it running again is to shut down mach3 and start again
This has also happened part way through a program, without me stopping the machine.
I am running the writing wizard.

Any help would be appreciated

General Mach Discussion / New starter HELP -Cannot jog etc

« on: August 02, 2011, 04:47:13 PM »

i purchased a small cnc with mach 3 several months ago and got it all working OK.
Now after a long break I have connected to a new computer, but cannot get the Mach 3 to respond, either with the CNC connected or without. I cannot even perform a simple jog.
Obviously Ive overlooked some very simple setting or switch, but I am tearing out my hair just to get started
HELP PLEASE
