In my attempts to add the Z Axis tool to my Acro, can anyone tell me the basics behind using this stepper motor with Blackbox X32, i.e. software changes required, cabling looks straightforward, Also how would a G Code Z command work, i.e if Z = 10, then goes to 0 what would that do with the stepper motor ? Lookinng at the screw/slide type so presumably the stepper turns a certain amount and I'm guessing this would need calibrating somehow ? Also anyway to add a safety switch to these ? thanks for any help.
The command for the Z would be the same for the other axis. If your Z was at 10, then you would have to command the Z to go -10mm to get it to zero. Yes the Z has to be calibrated just like the other two axis. You can add a switch just like the other axis. You may have to figure out how to mount it. You can watch the videos on how to build the LEAD 1010 to see how the Z axis limit switch is wired and get ideas from that. You will then have to make sure the machine is configured to run with 3 axis vs the normal 2 of the acro. If you have other questions, they can all be answered here in the GRBL Wiki. If you read this, you will understand how these machines work and it will make things easier for you. GRBL WIKI You also need to read this to make sure you hook everything up correctly. If you mis-wire limit switches, you can damage your X32. docs:blackbox-x32:start [OpenBuilds Documentation]
