Hi all,
Recently I had an operator have the block skip switch turned on, and so the machine did not home itself before excuting program.    frown.gif  Unfortuanlty he had a G92 Z0 set on the machine.(Not knowing the true repercussions of his actions went ahead to run program thus ..... U all know what crashes sound like..  graemlins/firebounce.gif  

So I went through it with him..  graemlins/rtfaq.gif  

What I want to know is how or where in the MPMaster post I can tell the code to not put in block skips.

You can change a switch in your post to shut off block skips.  Should look something like this under the "common user-defined variable" :

bld     : 1     #Block delete active

Change the '1' to a '0' and it should shut off the block skip function.  Assuming your post is V8 or newer and not an updated V6 or 7.  Let me know if that doesn't work.  graemlins/cheers.gif

In your .pst file, look in the psof post block.

Kevin, ouch!!! 1" rougher
I am sure someone will be on soon to help you with the post. Looking at your code, i am not sure how failure to Zero return would crash machine. my code looks the same, but no zero return.

You'd need to search the post - maybe the psof postblock for lines like these:

        pfbld, n, sgabsinc, "G28", "Z0.", e
        pfbld, n, "G28", "X0.", "Y0.", e

and change to

        pbld, n, sgabsinc, "G28", "Z0.", e
        pbld, n, "G28", "X0.", "Y0.", e

Don't you mean

and change to

n, sgabsinc, "G28", "Z0.", e
n, "G28", "X0.", "Y0.", e

if you just output pbld, it will output the block delete only if set by a canned text. If you have pfbld, it'll force the output of the block delete anytime. So you can just leave it to pbld.

Dave, I changed psof postblock like you sugested and it worked awsome first time around.

I appreciate everyone's input.
