Restarting File Plan

[Stephen50]

I'm cutting a large file up to line 21,262 with no end in sight, had to quit last night and I really don't want to start all over again. What is the procedure for picking up from where I left off at and completing the project?

What controller are you using?

[Adrian]

The ShopBot software has the FG command which will ask you from which line you want to start the cut from. There have been numerous reports from people on the ShopBot forum who have problems with that though especially with the latest 3.8.x versions of the software. Some things to consider are the starting postition, move speeds, spindle start commands etc.

Personally for the few times I've done it I've actually edited the SBP file and removed all the lines that have been cut but leaving the setup code at the beginning so I know exactly what the file is going to do when it's restarted.

My machine controller (Shark Pro Plus) software has a pause button.
I click on it, turn off router and leave everything else powered up.
In the AM I just turn router on and resume cutting.
Done this many of times with no problems.

You can do the same with the ShopBot but I read the question as he had already shut everything down.

hi
When i do a large file i have an habit of taking the line number of my file about every 15 minutes or so that i write down.
Like this if something ever happens i don't ruin my work. I use Mack 3 controller. You can even shot down your machine
and restart your work at the desired line minus a couple of lines less.
you start at x0 and y0 z0 ,go to the desired lines and start. don't forget to raise your cutting tool.
I suggest that you practice a couple of times so you feel confortable with this. It is a good way of knowing your cnc.
