can you speed the z on the fly

[steelcnccutter]

This question is can i speed the z axis like the x and y on the fly?
and i did not read the manual that i do not have or have i taken the time to download it. thanks

[Gary Campbell]

Steven...
[Space] to pause
[I] to insert command
[M][S] to open Move fill in sheet
change Z speed to desired
[Enter]
[R] to resume

Gary, thanks much for the help. it is great to have such a resource community to count on.

I could have used this information a long time ago, thanks Gary. I know how to increase the feed rate but never knew you could increase the z at the Bot.

Could you explain the purpose on the I command, I am not sure I understand the reason for it.

[Gary Campbell]

Rick...
It is one of the options available in the "PAUSE" dialog box. As stated above, it allows the operator to insert a command.

BTW, these and other seldom stumbled upon commands are available in the manual and/or the documentation included with every version of the ShopBot control software. Most operators cant believe what is actually available to them. This is a little out of the box, but most are linked to by pressing the help command.

Can this trick be used to decrease Z zero to say take a whisker more off a job without going back to Aspire etc.?

MANUAL, we don't need no stinking manual!

(tongue in cheek)

Bob, Nudge in this case or Move Nudge when not running a file will do that.

You mean we were actually suppose to read that stuff. Actually i did back before i knew where the on/off switch was which meant i had no earthly idea what it meant.

@bob yes you can increase z.
I think I can explain the correctly I know i use it all the time. After you have zeroed your z and you decide you want a deeper cut open up your VA screen. In the new z location increase it ever so little because a little goes a long ways. Basically you are fibbing to the table about where the bit is at. If your home is 1.0 and the VA was changed to 1.01, the bot would cut 1/100th of an inch deeper.

This fibbing value should never be more then your safe z or you could end up with cuts where you do not want them.

Now hopefully I explained that right or surely someone will correct me. @scott, thanks i have never tried that way

the picture shows a z home of 000 and the va is .01

This is what i do in order to not have to go back and redo files....this is mostly for cutout toolpaths when your material might be more then .75.

When i see that it hasn't cut deep enough I go back and send my tool to home position of 0,0

then I do a MZ 0 to get my Z to the material surface. The surface usually isn't there because its been cut away.

I then bump the bit down .05 or .10 (now you are at -.10)

I then Zero my Z at that position

Then rerun the toolpath and it will rerun the toolpath but will now cut that .10 deeper

You have to be careful not to go too deep on each increment that you lower it. This takes about 30 seconds to do without having to redo your toolpath. It works for me

Jack's reply is exactly the reason that a few more of you might want to read the included manual and help files. There are other ways to skin that cat.

problem: Z needs to be .010 deeper

during a file try the following:

[Space] to pause (z lifts to safe z, lets assume position 1.000)
Select [I]nsert command
[V][A] to open fill in sheet
for the Z position fill in 1.010 (ten thou higher)
[Enter] to close VA sheet
Select resume to continue running the file or quit to end it
[Enter] [Enter] [Enter] to rerun the same file.

As Scott says, [N]udge will work also.

You do not need to move the X & Y to 0,0 postion, move the z to 0, or move to a negative value and rezero. You simply need to tell the software that the bit is ten thou higher, therefore it will plunge ten thou lower when the file is rerun or resumed.

"Manual, I dont need no stinkin manual" is an old quote from Jack. You may want to rethink that position.
