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.
I'm currently doing the Solunar box by Michael Taylor. When I am using the V Bit, the CNC raises 1" at the start (the Mach 3 software still says 1.800, but the bit raises 1 more inch, so physically its at 2.8, but Mach 3 still shows 1.
. When I use the .25 EM, the CNC goes down 1" when I start (in other words it starts at 1.8, lowers 1" to physically be at 0.8 and Mach 3 still says 1.
. Each time I reload the file and then manually set the bit to Z zero, it works fine.....
