What's causing this?

[ken_rychlik]

Have you tried reversing direction? climb/conventional ???

I also use Vector ... (Vector 12 now!). I agree it is a good product. It can now process Rhino files even and has quite a few features. IMSRVE continued to support their product. Just support is limited , I believe , to latest version only. If you want to send me the file I can try it on my PRT. (furnituremaker atabout live.com).

I'll volunteer to toolpath in PartWorks, Aspire or ArtCAM Pro if you send me it as a DXF or EPS. This would eliminate it being Vector. Let me know the following:

1) Zzero on top of the material, yes?
2) Material thickness?
3) Stepdown
4) Speeds (you can modify via FE)
5) Bit diameter

Also, have you tried Scott's suggestion of cutting in a different location on the table?

That snippet of code runs smoothly on mine and I see no indication of any hiccup in the code.

You haven't answered as to whether the machine actually pauses at that spot or if it's just a bump due to a mechanical issue and does it happen somewhere else on the table as well.

The only other thing I thought of was that way back when, there used to be an issue with loops from CG's and you needed to take values out to 6 digits past the decimal point instead of the default of 4, but the divot is happening well before the corner which leads me to believe that you may have a divot in a rail.

Check to be sure one of the workers/helpers doesn't have a rubber mallet in his back pocket and that he doesn't give it a whack at just the right time when you're not looking. In the picture, the divots are close to the same, but not exactly. He needs to work on his timing just a bit.

Let me know the following:

1) Zzero on top of the material, yes? ===> Yes.
2) Material thickness? ===> 1.75 ins. Mahogany.
3) Stepdown ===> 6 passes
4) Speeds (you can modify via FE) ===> 1.3 ins. per sec on the PRT-96
5) Bit diameter ===> Amana 0.5 ins. spiral upcut.

Also, have you tried Scott's suggestion
of cutting in a different location on the table? ===> Not yet.
Client difficulties in pressing on, at the moment.

It's getting close to going home time, here
but a few quick answers to you helpful gents...

The client expects miracles without even confirming an order, or making a down payment.

We're not about to cut much more expensive mahogany, thus we're holding back a bit on this particular project
thus my not having made any further experimental cuts at difrnt parts of the table, etc.
but this will happen soon, after corrections to Z, which may well be part of the problem!

We have some Z issues with one of the two circular clamps that hold the Porter Cable to the Z column
-those should be addressed tom. a.m. since we have two new hose clamps and carpet tape
---just waiting on the boss to get back in town and we'll fix it up hopefully
...it takes 4 or 5 hands, needs squaring up too!

and I see no indication of any hiccup in the code. ===> What I thought

You haven't answered as to whether the machine actually pauses at that spot ===> No it doesn't.
or if it's just a bump due to a mechanical issue ===> More and more, it's seeming so...
and does it happen somewhere else on the table as well. ===> I dropped the X and Y motors this morning
and rolled the gantries around a bit -they seemed OK
but for an abused machine of 10 yrs. old, it's kinda hard to judge?

Running a finger along the rails(which prob. need replacing?)
there are minor inconsistencies, but nothing glaring.

Problem could be a combination of dodgy rails and fluctuations in Z?

The only other thing I thought of was that way back when,
there used to be an issue with loops from CG's and you needed to take values
out to 6 digits past the decimal point instead of the default of 4,
but the divot is happening well before the corner
which leads me to believe that you may have a divot in a rail. ===> It's not the smoothest!

Check to be sure one of the workers/helpers doesn't have a rubber mallet in his back pocket
and that he doesn't give it a whack at just the right time
when you're not looking. ===> Life in da tropix, huh? You live here too? LOL

In the picture, the divots are close to the same, but not exactly.

As stated in previous post, I haven't been too adventurous re. cutting elsewhere/experimentally
coz this is expensive Mahogany and the client is...well.....never mind...


and like I said, there ARE Z issues to be corrected and then we'll get experimental, I'm sure.

This problem has to be physical/mechanical....rails, fluctuations in Z or in Y(rails)....

I also use Vector ... (Vector 12 now!).
I agree it is a good product. ===> So we're 'slightly behind' with V9 huh? LOL

IMSRVE continued to support their product.
Just support is limited , I believe , to latest version only. ===> That may explain
why we haven't heard zip from them about getting our Vcarve (sp?)program working again.
Thanks IMServe.

===> ..I just sent it
Almost certainly now, this prob. is mechanical? not in the Vector geometry or the N.code
(furnituremaker atabout live.com).

IMServe's service overall is not impressive.

If/when we change software, I doubt we'll go the IMServe/Vector route
which is a pity.

If they want me to change my mind, they might respond to last week's email?

Hose clamps to hold a router in place is kind of scary all by itself. They make real mounts for those things you know.

Hey, this is life on a small tropical island.


This is Carlisle Bay -about 5 mins. away from my house!


Wouldn't be fun if we weren't using lo-tech stuff like Bamboo an all.

We bin using two stainless-steel hose clamps to hold the Porter Cable in place now
for ten long years.

It works... most of the time....but tell me about those Real Mounts.

A URL would be nice..

[Brady Watson]

That mount is junk. It was OK for a PR back in the day that didn't go over 2 IPS and Z speeds 1 or under. The machine probably had enough slop in it to mask the flex in the mount. Get one of the cast AL ones:

You'll have to call SB for a price.
