Suppose I carve some text and it turns out that my z zero is a bit high (letters aren’t quite deep enough. Is there a way, in gSender (1.4.10) to adjust z zero without forcing the bit into the work piece?
Currently I go to the measured (with the auto zero probe) z=0, manually go to z=-0.5 and then I zero z again, raise the spindle to a safe hight and start the job. This seems entirely too awkward and I figure there must be a better way. An alternate way would be to move the spindle off the work piece in which case I can adjust z zero without forcing the bit into the work piece but that’s even more awkward.
In vectric the solution is what white wolf sais, change the starting depth of the carve a ti.
If I need a spot on precize z0, I don’t rely on zero blocks. I shine a light behind the bit and creap z down untill there is no longer light leaking between bit and material.
I found zeroing off the blocks not as accurate as the lighting methode.
You just need to tell your machine that it’s 0.5 (mm, I’m assuming?) higher than what it currently thinks. I’m your example, go to Z10 (nice and clear of workpiece) and tell the machine you want that height to actually be Z10.5. This will cause your cuts to all be 0.5mm deeper.
The way you set that height would be to send
G10L20Z10.5 when your Z is at the current Z10. This shifts the entire work plane down 0.5mm.
You can click on the coordinates in gSender and type in whatever you want. So instead of jogging to -0.5 you can just click the Z coordinate and add 0.5 to whatever it’s at. This is a graphical way of doing what @NeilFerreri suggested. Setting the Z coordinate higher leads to the carve going deeper.
Thank you Neil, that is exactly the solution I was looking for. While going back to the post processor seems to also solve the issue, my setup is a bit too involved for that (go up a floor, grab the computer that runs Fusion, do the changes, post-process, run back downstairs, load the new program and find out that the height is off for other reasons)
Michael, I was not aware that I could enter a Z coordinate manually like you suggest. I will need to check that as it seems very intuitive to me.
changing the z height in the readout box works a treat and makes it soooo easy to sneak up on the right height.
I use dogholes and pegs to hold my stock - making sure it is wedged good and tight and giving the stock a tap with a rubber mallet to make sure it’s seated all the way down also helps. I completed four little trinkets in my first '‘production’ job
