Link problem

[davebryant]

Hi all,
I'm making the jump from KCDW to Ecabinets with my first full kitchen.
I have all the blind dado case parts cut in 3/4 and 5/8 perfectly with .374 bit (#11) and 5mm air drill (#31). Now trying to cut blind dado drawer parts from 5/8 and 1/4 birch ply with .248 bit (#12). The drawer material is set up as tool group 2. After manually starting the spindle the spindle will turn off, then jog across the table and come to a crashing stop. Then I get a 'missing comm return' message. It always stops at exactly the same position on the table so I'm ruling out a random comm error. I think I have everthing set up right according to Gary's videos but I must be missing something.

Missing comm return would imply something physical (wiring?) or electronic with the machine itself - not with the link software.

[davebryant]

There is also the issue of the spindle shutting itself off.

[zeykr]

A call to shopbot would probably be best idea.

In the meantime, Does the spindle shut off when it quits in the same place each time running the link or at other times. When spindle shuts off are the SB3 indicator lights still on for outputs 1 and 4? When spindle shuts off does it come to a quick halt as if you had turned off output 1, or does it slowly wind down?

Is this a new problem or have had it for a while?

Know this question is always asked, but is machine and dust collection grounded properly?

Dave...
If you are going to be near your machine tomorrow, email me at the email in my signature (red). We can work this out over the phone.

Ken,
The problem has never arisen before with any other software. Here is the sequence of events:
Shopbot 3.38 opened by Shopbot Link
output 4 on, input 1 off
ENTER SHEET # dialog...enter
LOCATE SHEET...enter
output 1 now on
manually push start button
output 4 shuts off
spindle shuts off and jogs to X23.783, Y23.461
stops very suddenly
MISSING COM RETURN message
try to exit Shopbot
STOP BUTTON HIT dialog LINE 27...resume
nothing happens...file still running but stalled.

[Brady Watson]

Are you running dust collection? Is it grounded really well - as in bare copper wire thru entire hose end to end?

-B

Working with Gary over the phone will be the best thing.


This part of your sequence bothers me:

manually push start button
output 4 shuts off
spindle shuts off and jogs to X23.783, Y23.461
stops very suddenly

With std shopbot setup, Output 4 should not shutoff when you hit the start, and it should not be moving with output 4 off. If output 4 does go off, the spindle should stop at least on an alpha, both 1 and 4 need to be on for spindle to run.

Will be interesting to see what it turns out to be.

Brady,
I've been on the phone with Gary this morning and he wants me to check the grounding and the Estop switch wiring...in the meantime I've sent him the export files to look at....really appreciate your time, Gary.
Ken,
Yes, it will be interesting to see how this pans out.

[davebryant]

Brady...I think I will take your advice and run a bare groundwire through the inside of the hose...the hose has a spiral wire in it that's grounded with jumpers, but I'm sure one run inside the hose would be better.
