Restarting a file at a specific line number?

[tablebuild]

I am unable to find a way to restart a file at a line number in the book or by guess work on the computer. Does anyone know if this is still possible?

Under file look for[G] goto line/ single step. then load file, start and a box will appear to input the line you want it to start at. Be careful that you are about where you want to be before you tell the bot to run because it will put the z height first and move x & y next. I have lost project with deep cuts in wrong spots when using single line start.

You should be able to use the [FG] [filename.sbp] command. You have options to GOTO a line number and/or RUN FROM HERE. Hope this helps.

Say line 387 is

M3,12.7453,36.8035,-0.3754

and you want to resume from that line, you need to reach for that position (with the tool) first before using the FG command to resume from that line.

If not, say you resume at this line (above) from

0,0,0

it'll move from

0,0,0

to

12.7453,36.8035,-0.3754

doing a niiicccceeee loooonnnngggg cut in your material.

Hope that help.

I wish ShopBot could make a post at the technical column about the FG command and resuming a cut with it. A year or two ago, someone from SB sent me a pretty good document about it.

One thing I discovered last week when using the Go To Line command is that the move speed (MS)within the file is not recognised and will revert itself to the ShopBot software default.
You must change the move speed (MS) to the values you have previously set in the file before running the routine.
I have informed Ted at ShopBot about this issue.

Another way of looking at GO TO LINE 387, would be.... "Ignore all lines before 387"

You could also run the header portion of the file, to load variables and parameters, then jump to the desired line, and run from there. As Paco says above, you will want to position the tool in a position so that the first move it will make does not damage the material.

As others have said, starting at the desired line can result in Paco's "loooonnnngggg cut". One approch to prevent this is to start a few lines early.
Stealing from Paco's example say the present position is 0,0,0 and line 385, 386 and 387 are:

MZ, .5
M3,12.7453,36.8035,.5
M3,12.7453,36.8035,-0.3754

IF you want to resume cutting at line 387 in this example one approch is to restart the program at line 385.

Another way is to edit the file to make sure it acts nicely. Create another copy, delete the lines already cut, insert the above mentioned move command(s), and go from there. This is what I usually do to make sure everything is well behaved (after having the ugly long cut through material fiasco happen to me).

Quote "You must change the move speed (MS) to the values you have previously set in the file before running the routine."

This is a very good tip, Mark - and worth noting for those that try the FG command. Since the FG command will skip to the line that you enter, it will skip the MS command in your SBP file, and if you were just flattening your table at 8 IPS, that may not be ideal, depending on what you are cutting when you use FG.

It will also skip any SO command to turn on the router/dust collector etc. Instead of using FG I usually insert a GOTO TEMP command after the needed startup commands at the beginning of the file, add a TEMP: label line where I want the cutting to resume, and then run the file normally.

Of course you have to remember to remove the GOTO line if you ever plan to run the file again in it's entirety.
