Z Axis 1" problem
|
I have Mach 3 software with a CNC from RouterParts.? I use Vectric Aspire 10.? I can't figure out what my problem is.? Each time I zero the Z axis (manually) and then load a file, my bit offsets by 1".?? As an example if the bit is at a Z height of 1.800, with the file loaded, when I go to "Start Cycle" the bit raises another inch and proceeds to attempt to run the cycle 1" above my material.? If I then hit reset, close the file, re load the same file & re zero the Z axis (manually), and then start cycle again, the file runs correctly and the bit is OK.?? I have also had the problem where the bit lowers 1" from the 1.800 height and then proceeds to DIG into the wood project (I now know better and watch with my kill switch every time before this has a chance to happen).?? Any ideas what is causing this behavior?? Its very frustrating to have to re zero 2x for every file.? Thanks,? Rick Wize

开云体育Do you have a 1" tool offset defined
for that tool? If so, set it to 0. Look at the height column in
Config->tooltable.

Does this help?? It is the Profile Cut rhat wants to go 1" lower than Z zero when I first run the program after setting Z zero;

开云体育You have a line?G00G20G17G90G40G49G80 that turns off the tool length compensation in Mach 3. ?Three lines later in your program you have?G00G43Z1.8000H2
which turns on the tool length compensation in Mach 3 for tool H2. ?Check the tool table comp values in Mach 3 and see if there is a value for tool number 2.
If you don’t want tool length compensation at all you can edit the program and remove that G43 code and see what you get.
As another thought you may want to check your tool?definitions in Aspire. ?I use Vcarve Pro and have found a couple of instances where I have?inadvertently added a Z-value offset when setting up the job.?

If you are using the standard screens, try clicking on the thin REF ALL HOME button as well
as the ZERO buttons. I saw some weird offset problems once till I did this. Regards, Les Grant. On 29 Nov 2019 at 7:46, Richard Wize wrote:
