    Default Breaking Bits After an "S" stop and "R" resume

    The problem that I am having has happened before using the "S" and "R" keyboard commands.

    I often use Aspire V2 to create "peck" holes for cabinet shelves.

    I have stopped the peck drilling program using the "S" soft stop command with disasterous results after starting again.

    The procedure:

    1. To resume, I use the "R" resume command.

    2. This is when the problem occurs. The machine tries to move to the correct depth WHILE STILL MOVING IN THE X and Y Position. It should move to it's new position first (ie moving in the X&Y only) before drilling the peck hole. The result is a broken bit and damaged cabinet.

    What is going on?

    Has this problem happened to others out there? I would like a solution since I often use the "S" stop and "R" resume keyboard commands.

    Thanks
    Tom

    The resume button should not be there.

    They should say (quit) and (destroy work) instead of resume. Foolishly I tried it yesterday and it lost z position and resumed without starting the spindle. Another broken bit.

    Please report it to shopbot, but from what I can tell this is normal. It will not resume on my machine with success and several othres that I know of.

    This is just a guess but it sounds as though the software thinks it has completed the last hole and is 'resuming' at the next hole. A suggestion would be to use the variation of the resume command where you specify the line number to resume at. Insert the line number for the hole where you stopped. The line number should be just a few less than what is displayed when you hit the 'S'. Just a thought. Try a simple test without the bit in and see what happens. Russ

    Russ, it used to resume fine with the 3.5.xx sb3 software, but not anymore. Which version are you running?

    I've found that-at times- upon "Resume" the feed rate slows to a craw

    I've never had ANY luck with the stop, pause or resume feature. I've broken a lot of bits doing what Shopbot told me to do (to bad I can't bill them). I've found that the safest, but not the most time saving thing to do, is start the file over from the beginning. Then I know I'm safe. If the material hasn't moved on the table, you should be ok.

    I use the E stop or the stop by hitting the enter key and then can restart with no problems all the time also before it starts it asks if the spindle is on.

    the enter key is not is not but it does seem to work. when I first got my bot hitting the space bar wouls cause those issues so I got in the habit of hitting enter. though sometimes it is not fast enough. I have ad the slow thing happen before too.

    I get the slow move speed thing consistently if I stop and resume in a 'complex' command like CR.

    I do stop and change speeds then resume pretty often with no ill effects.

    I assume (hope) that Shopbot is monitoring this thread. It is an extremely important problem since we should always have the ability to control the machine in a safe manner. I do not have the time to call Shopbot and I am frankly shocked that this problem is happening in the software.

    There should be an easy fix for the Shopbot programmers to add the appropriate "conditional statements" in the code when using the "S" and "R" commands. The question is whether they will deem this problem important enough to act. But perhaps they have fixed this problem years ago and I simply haven't installed the newer version of the Shopbot control program.
