C2 - Z-Zero not working

[bill_lumley]

The C2 Zero routine for Z goes down , touches and comes back up all of 1/4 “ and then goes down again .It comes back up the same amount and says it is happy at the new level of 1” which clearing is WRONG as I can see the bit is only clearly ¼” above the table . How can this happen and more importantly be rectified .

Thanks Bill

Bill...
Can you explain what you were doing, and what version of SB3 you are using and which version of the Zzero file you are using?

Did this just happen after a software upgrade?
Did you make any other changes?
Is it repeatable?

I have SB 3.6.1 and eCabinets Link 1.0.9 that I have updated in the past week . I think I have only zeroed my Z twice with C2 since moving to 3.6.1 as I have only been doing air cuts to get th e-cabinet link running . The only other 'event' today is once I forgot to turn my spindle on when a cut started and the Z did a head butt on the table while I fumbled for the stop button but I was ale to Zero properly and do more cutting after that event .

Bill...
If you run the Zzero again... does it work properly? Did this happen more than once?

One last question, was did this happen during a manual bit change in an SB Link file?

Yes it is repeatable . I tried about 8 times and the same thing happens each time ...

Bill..
Run the zzero again until it makes the error.

Then run [U] [L] command to list variables.
Save the file (lower left corner)
email to me

Open the following file:

C:\SbParts\Custom\Custom2.sbc

At the top of the file the first few lines is the change history. See if your file is newer, if so something may be different there and got loaded when you updated your SB3, you can switch back to an old version of Custom2.sbc if that is the problem.

Mine shows:

'ZZERO.SBP -- Example File showing how to Zero Z Axis on contact plate

Hope that helps-

I am new to ShopBot and took the beginers class.
We used MDF to make our project. I tried using can spray paint primer on the MDF and the paint just soaks in.
Questions:
1. Is there a special MDF that takes paint?
2. What is a good water base primer to use?

I do have a HVLP sprayer.

Thank you,

Ralph

Ralph- howdy! This really should be the start of a new thread, that way people will be able to notice your question. People reading this thread think you are talking about ZZero issues.

As to your question, I dont know of any special MDF.. if it were me, I would use a filler/sealer just like porous wood. MDF is very porous. Once you get a nice flat surface, put your top-coat on. Your top coat will have to be compatible with the filler.

There are other folks on here, especially in the sign threads that will be much better at answering this question than I.

Good luck, and welcome!

Ralph,
Carpenters glue thinned with water makes an inexpensive sealer for mdf and can be sprayed.

For outdoors applications you can seal with thinned epoxy before painting.
