Vertex V-HV-4 & HBM BF 25 Vario to Nema 23 bracket

cults3d

I played around with some leftover stepper motors and drivers, so I created mounts for them using a small milling machine I own. Although the ABS plastic might not be strong enough, I still wanted to give it a try. Sure enough, the bracket for the Z motor broke slightly between layers during installation. Fortunately, it was easily fixed with acetone. It's possible that this wouldn't have happened if I had printed these brackets in higher resolution. In this case, I printed them at 0.3mm resolution because I used 3mm filament and wanted to save time. The infill used is 60% because I feared the plastic would not be strong enough otherwise. The first test was milling a bicycle shape out of MDF. The only issue during this test was too much play in the motor-to-shaft connection. I fixed this by putting some nylon blue tape in the motor-to-shaft coupler. I did this on both the Y and Z axes. Unfortunately, I forgot to take a photo of this milling test (but you can see it standing in the background in one of the pictures). After that, I tried milling plywood. This time, I made an Hex-Key holder consisting of two parts. I wanted to test the accuracy of the machine with these plastic mounts. It was good enough to make the two parts fit super tight. I just tapped them together and the connection is held by friction alone. But as you can see on the photo, I needed to clean up a lot after it came out of the milling machine. And to be fair, these tools are meant for metal, so I decided to test aluminum. This time with a 4th axis. In this test, I milled a gear. You can see it in one of the pictures. In this case, I made a gear with 36 teeth because that's easy to make G-code. Of course, I first had to make its basic shape on the lathe. And yes, I could have done that also on the milling machine, but the lathe was faster. And yes, I know my setup is not very professional (see pictures) with the end switches. That's because it's an experiment after all. I may change it in the future or remove them, but that's not advised for beginners. Also, I know the display doesn't show the RPM of the mill. Still need to fix that sometime. So I can say that these plastic ABS mounts hold very well and the machine moves within 0.01 mm for now. The machine has run for around 40 hours now and all is still solid. The milling machine is a HBM BF25 Vario. The rotary table is a Vertex V-HV-4. The motors are Nema 23. The bolts I used are: 8X M3x10 and nuts 8X M6x60mm and nuts and washers The screws for mounting the bracket to the Vertex rotary table are included with this table already. If you have any questions, feel free to ask. Do you think I forgot something or made a mistake? Feel free to comment.
