Anyone know how to change the Auto Focus Height on the Atomstack A70 Pro. Looks like it is fixed at around 20mm. Supposedly there is a macro command to do this but it doesnt seem to work. $autoFocus/depth_max_mm=3.9
Did I read that right? You want to change autofocus from 20mm to 3.9mm?
Not necessarily. That was just an example of the command i found. Here’s what im trying to do.
When you do an autofocus it seems the default is approx 20mm above the workpiece. That would be the same as using the focus block on the Engrave step. What i would like to do is change the autofocus from 20mm to 15mm, or 8mm before i do an autofocus. That would correspond to the other two steps on the focus block. Or after i do the autofocus easily move the Z axis down 5mm or 12mm using a macro.To match the other two steps on the focus block. I know i could just jog the Z axis down manually. I know i can move the Z axis down in the Cut/Layer file. But i found when i do that it repositions the Z axis for every design element in the project which adds considerable time to the job.
I know what autofocus and Z-motion mean, but I have neither on my machines. Therefore, I have not experienced a workflow like you describe.
I figured it out. Simple, just make a macro with two commands.
First one does the autofocus
Second line moves the Z axis anywhere i want
So I have three macros for the three steps on the focus block

Does this machine use FluidNC? Curious about this syntax.
Do you know where this is documented?
This seems reasonable and perhaps the best approach.
You could potentially set a Z offset at the layer level to handle this depending on your workflow.
I tired Z Offset at the layer level and because it resets for every element in the design it extends the time to run the job considerably.
Here’s a pdf file with instructions i wrote on how to setup and use Autofocus on the Atomstack A70 Pro and Max. Just download and change the extension from .txt to .pdf
