Z axis will not drop
Hi Everyone,
We are trying to run a file output from V Carve Pro but the Z axis does not drop to the work surface. I have tried all the Thermwood Post Ps that Vectric has & the result is the same for all of them. I have reviewed the Code & can not see what would be causing this. I can run files I have produced with profile modeler or CN with no problems so it is not a machine issue. I have attached the file if someone could look at it & tell me if something is not right it would be appreciated.
Our machine is a 2007 CS45 running the latest updates.
Thanks,
Gerry

Re: Z axis will not drop
Gerry can you pm me the vcarve file although we do not have the full version of vcarve just the trial version we have ran some of the test files on our cs 45 and may be able to help. If I remember correctly there was some code that had to be changed I think that on line 22 of the file you posted G0 should be replaced with G51.allso graft the part before actually running it if there are any errors they usually pop up when grafting telling which line they occur on.Allso it would be greatly advised to run the program without the part on the table if this is your first try at this.
Yes! Oh Yes! I Think We Are Going to make It!

Re: Z axis will not drop
Hi Terry,
I tried that one also & the result was the same (program runs with Z axis 8" off work surface)
Thanks,
Gerry

Re: Z axis will not drop
I don't see anything too weird, but what's g800? I don't think I've ever seen this used on my machine. Also, I see a g901 and a g52l2, maybe take out the g901; I never use fixture offsets though so I'm not sure how that's supposed to be formatted. Also, what's m999 in the code for? I don't seem to need that in my code either, but maybe I'm using older software. Maybe format the header so it looks the same as when you post with profile modeler/control nesting and/ or check the daylight on the tool you're using and make sure it's right.

Re: Z axis will not drop
Hi Daniel,
I tried dropping out the G901 & it did not help also dropped out the M999 which is a macro for machine settings as I understand it some of the settings can be changed a& some cannot. I have no Idea what G800 is. I have removed most of this code & tried running the code & always the Z axis stays at the top of it's travel.
Scott,
I will read that post & see what I can gather from it.
I have a E mail in to Vectric & I am sure will hear from them the first of the week & will post back if I get this resolved.
Thanks,
Gerry

Re: Z axis will not drop
Hi
I have not got a CNC so I am looking at this as a new be and outsider.
is the Z axis coming down but just not making the work piece?
if so could it be that it thinks your work piece is bigger then it is ?
could you try telling it the work piece is smaller then it is?

Re: Z axis will not drop
Hi Simon,
The Z axis moves up when it gets located over the part then comes down an inch or so but is still about 8.5" off the work surface.
I may have the Z home position setting wrong in V Carve Pro but at this point I am just going to wait & see what the Vectric support group come up with.
Also I found out the G800 is an acceleration option.
Thanks,
Gerry

Re: Z axis will not drop
Gerry, I ran the code with the header formatted this way on my machine and it seemed to run fine other than I had to edit the T4 tool change, the tool name wasn't commented out.

Re: Z axis will not drop
Hi Daniel,
I formatted the code as you did & the file will now graph but when I run it the Z axis remains at the top of it's travel
If I put my G52L2 offset in I get a X axis out of bounds error on line 21 while graphing so I have some issue there also.
Thanks for you help,
Gerry

Re: Z axis will not drop
Hmmm, something is up with that, I'd look and make sure the daylight is correct and there is no z offset in your offset table. I always use g901/g902 because whenever I set a fixture off set that's located near where the pop up pins are I get that out of bounds error; so now I just have a shortcut to my m999 macro and add a negative offset to the g902 and use that instead. None of this should have anything to do with the z axis though, other than checking the daylight I don't know what else could be wrong, the g code should behave the same regardless of what program generated it.

Re: Z axis will not drop
Hi Daniel,
Both tools were measured a number of times & come up within.001 each time & no Z offset in the fixture table.
Something is strange for sure. I will try the G902 offset & see if that works better for me. I hope Vectric support can come up with a solution I am right out of ideas but as you say if the code will run on your machine it indicates a machine specific problem.
Thanks,
Gerry

Re: Z axis will not drop
Gary,
I attached a file that I use to set up the code for my 45. Copy the straight Gcode and paste into this. If it works I';ll send the PP.

Re: Z axis will not drop
Gerry Unless the post prossers have changed since I last did a trial file I had to set the offsets to the corner of the material closest to home just like using the carving programs thermwood has. Example your 902 position is x117 y63 and your part is 10wide and 10 long then the offset would be X107 Y53 this could correct the out of bounds issue I am still stumped on the z deal.Gerry A Brown wrote:Hi Daniel,
