Hi Shawn, thank you for that information, its very helpful. The backplane is metal. What would your recommendation be for grounding the cabinet? I have a busbar that I plan on running the ground from each device to, but still unsure of the best way to ground the cabinet itself. Would I run the groun...

Thanks Shawn and I was not sure whether using fuses or circuit breakers would be better (title shows some of my lack of knowledge and inexperience but I am trying my best with it all). The power will be coming from a 30A 208V feed from the circuit breaker that goes into a knife switch and then from ...

Looking for some advice on protecting the components in the control panel. I am open to any suggestions and input because I have reached a bump in the road with the electrical aspect of this project. I have primarily been looking at adding a fuse to the input of each device. I am looking at feeding ...

Update on a previous post, but in the process of building a three axis CNC gantry mill. For the most part, the mechanical side of the machine is complete for now and I am feeling good with where its at. I have had all three axis of the physical machine moving and have been fine tuning Overall Turns ...

Update on the build, for the most part, the mechanical side of the machine is complete for now and I am feeling good with where its at. I have had all three axis of the physical machine moving and have been fine tuning Overall Turns Ratio and Backlash compensation. Now, I have been working on final/...

Thank you for your help Wes. Another newbie question, but right now during the building and testing stages of the machine, I have the meanwell power supply that came with the Acorn connected to a standard 110/120 V outlet. If the spindle motor requires 230VAC, do I switch the power incoming to the m...

Looking for some guidance on selecting a VFD for my spindle motor and pairing it with the Acorn and CNC12 software. The spindle motor I am going to be using is a Suhner BEX35. I will attach a picture of the motor nameplate below. I am looking at the specs on the nameplate for 230V at 60 Hz since I h...

Another question regarding the wiring and electrical aspect of this project.

Using the three stepper motors and drives above, do I need a power supply for each motor and drive or is one sufficient?

Relatively new to the forum but have been getting great help on another project, so I figured I would seek some advice on a new project. We are looking to convert an old Lodge and Shipley 20.5” x 78” Powerturn Engine Lathe Model 2013 to be a CNC using the Acorn board. We do not use the lathe for act...

Update... Everything seems to be working appropriately so far. I have two out of the three motors and drives hooked up as well as a functioning E-stop now. Now going to work on configuring everything and adjusting some parameters as well as learning/experimenting more with the CNC12 software. Thank ...
