Multi pass keep tool down bug ?

[?Mark]

Running MCX MR2.

 

Here is a correct toolpath for multipass (3 passes) with keep tool down unchecked

 

Here is the same toolpath but with keep tool down checked (I want it this way).

Notice that tool stays down after 1st pass and retracts after 2nd pass. wth

 

What gives ?

Looks like it only happens when XY stock to leave is negative and fairly big (ex .200")

 

Can anyone confirm it?

Makes sense to me, How much was you multi-pass ??

 

 

PEACE

Which part?

 

It's a .375" tool doing passes every .150"

 

edit:

XY stock to leave is -.350 in above toolpath

[Hardmill]

Thats alot of neg stock, why not just offsett the geo.

I seem to remember running into this in the past.

That was quite a few brain cells ago

 

 

PEACE

[?Mark]

LOL.

I know how to work around it, but isn't what a negative stock is for ?

 

It took me couple months to design and make few prototype parts. Now just going thru toolpaths, making sure they're efficient for production.

 

I remember doing it that way in MC9 without a problem.

 

Edit.

Just tried in MC9 with exact same parameters, and no problem there.

 

It must be MCX...

I just had to do some toolpaths in V9 with excact same geom, cutter, toolpath type ect because MCX MR2 just could not cut it.

Mark,

 

I do not know the answer, but...

I would suggest submitting this issue alone with your MCX to [email protected]

[?Mark]

Thanks Roger.

Couple of weeks ago I sent in another issue I had a problem with and got no response.

 

I can't sent this part, but it can be easily repeated.

Just create 2" circle.

Use countour, climb (start from inside of a circle),use a .375" tool doing passes every .150", XY stock to leave is -.350 and use lead in/out with a line and a 90 deg circle...

everytime

Mark,

 

Just create a simple mcx file and send it in. The last one I sent took a week or two before they responded with a defect number. Besides, we don't want QC to start laying off people.

LOL. Not if I can help it...

Just did what you suggested.

Strange you guys don't get a responce from QC.

I always get a responce the next day from Rob Peirolo. He has been great.

Maybe it gets down under faster

[?Mark]

Maybe they're still on it.

 

Before this, I had a response within a day...

David,

 

I've dealt with Rob and Chris Bell in QC. I've talked to Rob on the phone a couple times. Nice guy.

Hi Mark

 

"Couple of weeks ago I sent in another issue I had a problem with and got no response."

 

We have received four e-mails total from you over the past year and a half. One was yesterday and the other three were from August of last year. We typically respond to e-mails in the order in which they are received, so you can expect a response for the one you sent yesterday in a day or two. Thank-you.

[?Mark]

Oh, so this one didn't get thru?

Mark - We got it this time. The SPAM filters may have stopped it on the first attempt. Thanks for your patience.

[?Mark]

My earlier comment might've came across the wrong way. I never doubted your commitement to a great service Chris or anyone at qc for that matter...

 

BTW who do I need to talk to make some suggestions for 2d toolpaths? There're some very easy to implement things that sure would come in handy.
