Title: "Z" Plunges Opposite Dir.
Post by: Overloaded on June 28, 2008, 09:56:40 PM
Hello,
Been a while since I was LCamming and I have a prob.
I've done all I can remember to get the following to run in Mach but the Z plunges up instead of down.
Stumped,
RC

I can not open your file but....

1 if you have not changed your machine then you have the incorrect goto... another words should be Z-0.250 (maybe is Z0.250)
2 you have changed your mach config...

check these first...

The Z jogs and runs normally otherwise...z+ goes up, z- down.

What else could be changed ?

Thanks,
RC

N35 G0  Z1.0000
N40 M3 S3000
N45  X2.0000  Y1.5001
N50  Z-1.1000
Is this correct
N55 G1  Z0.5000  F20.00
I think this is where you start to cut?
N60 G3  X3.5000  Y1.5000  I0.7500  J-0.0001  F66.00
N65  X2.0000  Y1.5001  I-0.7500  J0.0000
N70 G0  Z1.0000
N75  X0.5000  Y3.2501
N80  Z-1.1000
Is this correct

Your text is running around...... :D
Yes
n50    is no good ? ?
n55    goes + instead of - to cut depth

n80
n85  same thing

n110
n115  same thing

have no idea where 50,80 and 115 came from (LCam)

Never used lcam... but how do the fixture offsets work?
Can you set a bottom somewhere else?
Could it be in the post somewhere?
How about reverse posting? Can your program do that? Its like mirror...
How about Scaleing in Lcam? Can it do that?

Mine can do this stuff and if you get a little something outa whack its hard to find...

I opend it with both NCPlot and Rhino, it was at Z0 so thats ok...

You may need to update lcam? it should not loose that information...

How about reverse posting? Can your program do that? Its like mirror...     Not sure if that would help....used to work good. May drop back a Version or 2.
How about Scaleing in Lcam? Can it do that?                        Yes....but dont see where that would help either ?
Thanks for your time, I guess I'll just tweak the code for this one.

I'm running the same version as you and I 'm not sure why you're getting the reverse Z direction.

As for the fact of LCam saving the job "data", it never does for me either and yeah, it sucks because if you want to go back and change something, you have to start from scratch all over again  >:(

Chalk it up to being beta software, I guess but they really should make you aware of this stuff before you purchase the license though  ;)

Sorry I couldn't be of more help to you-

Hi, RC

Used your LCam file hear, Set the Cut Z to -0.2, Set layer then set all layers.

The tool #4 must have been in you LCam file, I didn't set a tool #.

Added a G55 fixture offset at x1 y1, Don't forget to save it.

G55 ;Fixture #2 Added chip

Hey Bud, I got it to post and run OK, (explanation below) but still cannot get it to save the LAYER info. Tried all I know.
Maybe Chip has a fix for it.

Chip, I was just hitting "Set Layer" only.. being the job was only 1 layer. The only thing I did different was to hit "set layer", and then "set all layers" like you said. Then it posted correctly and ran well.
Now....know why it wont save the layer tab info ?

Thanks Guys,
RC

Glad to hear it, my friend.

As a side note, I asked over at the Mach 3 Yahoo forum if there was a way that the data could be saved and Art actually replied and said his saves it so I'm waiting on a reply to see how he goes about doing that.

Cool Budman....keep us posted of any updates if you will.
And keep you fingers crossed for LTurn as well....it looks to be very promising.
Thanks again, I'm grateful for all the help I can get.

Hi, RC, Bud

No answers hear. The Bata ver. (Pro) was $60.00, now $75.00, That get you a full release ver. When it comes out it will be $150.00, I Think.

Hopefully there will be further work at some point, Id' start a note book or TXT file for the data you need to keep.

Thanks, Chip

Well, it's interesting as one of the fellas over there says his saves it just fine and another says some of his files save and some don't so I honestly don't know what to say here. Luck of the draw maybe? lol!!

Ah well, we'll wait and see-  :)

Interesting Budman....thanks for the update.
Also strange, reply #10 from this topic. A different "SAVE", but works on 1 PC but not the other.

RC,

Excellent news for you, LCam is now working/saving for me. I completely uninstalled Mach 3 from my system this time(not my machining system) and reinstalled everything again.

I'm again using v3.00.2 and it is actually saving now. What's VERY interesting is that my older files WERE saved but wouldn't show up as saved. The whole thing is very odd but it's definitely working now.

It's worth a shot!  :)

Post by: Overloaded on June 30, 2008, 03:06:49 PM
WOW...I'll give that a try later this week.
I did notice also that when opening the LCam project, with all of the Layer info zeros,  if I post the code without changing anything, it goes through correctly. Like you say...it's saved in there somewhere, just doesn't show.
Thanks again,
RC
