Cnc Base For Prolight 10003/25/2021
I believe there is a 2:1 belt setup between the spindle and motor and I am investigating how I can place the encoder on the motor fan mount.If you are looking for a CNC retrofit project, this is the machine to use.
It was built with an epoxy granite frame, sports a 1HP spindle (5000 RPM), 2.9 AMP stepper motors, and has 19.5 x 6.25 table. If you are lucky you may get the optional tool changer, or maybe a fourth axis with your purchase too. While this one came with the spindle speed controls (mounted in the rear), it did not have the motor control box. So, we are going to use the AcornCNC controller board and a Gecko G540 to get this machine moving. Table That machine weighs a little less than 500 lbs so I had to build a frame for it to sit on. Electronics The spindle speed is still set via the original manual controls, but that isnt that big of a deal. Adding an encoder on the spindle should help resolve that manual step. I posted the components I was planning to use in the description. Here you can see that I took an old electrical enclosure and re-purposed it. A lot of the cables would have been at strange right angles within the enclosure. At the last minute a friend with a laser cutter helped me mount the G540 on a piece of Acrylic. What is not seen in the photo is where heat sinks were applied to the back of the G540. When I get back to it I will need to include a CPU fan, move the E-stop to the top, build doors (probably also arcylic now), and mount it to the side. That vise is too big Remember that table size Yeah, you can mount a 4 Kurt vise at a 90 if you would like, but you lose a lot of Z in the process. So I got on the olAmazon and got a crummy Chinese vise delivered. Unfortunately, the dang thing must have been ground in with a belt sander. I think I found it 0.013 off, and a nice concave shape on the bottom. You get what you pay for, but nothing a little grinding wont fix. I was planning on running Titans of CNC tutorial on it, but decided I should just do a simple test cut. These profiles set for example the line segment lengths used in circular moves. If you look closely you will see there is a good.125 line segment on that island. Whats next Well, I have an encoder waiting to be mounted on the machine.
