Sure. Hope it helps you. Post a link to your kickstarter on here when it is up and running. I would love to check it out.

@@RealNightwork thanks, check out samurai_machine_tools on Instagram to keep updated

At the time of building this machine they were the straightest and flattest things I had access to. I now have access to better things. If you would like i will measure one on a AA lab grade granite surface.

They are half inch lead screws

The frame was all made from left over material from another project. i designed it around what I had.

This machine was not designed to machine ferrous metals. It might be possible but it would not work very well.

This model has supported shaft and ball bearings for the rails. It is cost effective but one day I would like to upgrade it. It also has precision acme thread and anti-backlash nuts. I got a lot of my parts for this build from surplus places or from my university cleaning out storage. I was collecting parts for the build for about two years and then designed a cnc around those parts.

This project got a little side tracked. I used it at work and then it turned into a work fixture for about 2 years. I couldn't share anything about what we were doing with it because intellectual property.

This machine is a hobby. I wanted a cnc mill for my personal projects. But many people do earn money from selling various cnc machines, or using them to manufacture parts.

I dont have any written plans for this machine. But in the description you can find a link to the hackaday project page. That has some more details and some photos of the build progress. Feel free to send me a private message through hackaday.io. I can try to take more photos and video of specific areas if you want, and answer questions about the build.

The entire machine fits inside a 24 inch cube.

did you rebuild it?

Sorry, I have more than one google account and when I replied I was logged in on my other one. I did build the machine, and the Tank Chain account is mine as well.

The spindle is from a Taig Mini Mill. It is a good starting point and accepts any ER16 collet. Since it is a complete unit you can avoid a lot of worry about the bearings alignment and loads from cutting being transferred to the motor. Since the Taig spindle assembly has a stepped pulley on it, I can select which ratio I would like to use from the motor to the spindle. The motor also has a speed controller on it. But even with the speed control you are limited in how fast or slow you can run the motor efficiently. With the step pulleys i can pick ratio which lets me run the motor efficiently, and still get very slow or very high spindle rpm. Another advantage is if the cutting bit is slowed down while cutting the belt can slip on the pulleys, or even break. It is much cheaper to replace a small v-belt than the spindle or motor.

It is a combination of plates and corner brackets.

+Gavin Luis D'Mello The stepper motors on the X, Y, and Z axis are 280 OzIn Hybrid stepper motors from Probotixs. The spindle motor is an AmpFlow E30-150 dc motor. One nice thing about the spindle motor is AmpFlow makes 3 versions of this motor that all have the same mounting dimensions and only slightly different length. This motor is the 1 HP version and the least expensive. But I can upgrade to a 2.3 HP or 3 HP spindle motor very easily.

+Mtaalas It is not actually that dangerous when you have been working around a machine like this for years. I understand exactly what can happen. Also, the video makes it look much closer than it really is. Another thing to consider is the timing belt is quite loose so even if my finger were to get caught (highly unlikely), the belt would stretch. There is also no cutting tool in the machine which makes it much safer. All that being said, I have plans to put a nice acrylic cover over the timing belts mostly to keep dirt out. Please be careful when working on machines like this. Be aware of your surroundings, how to cut the power, and wear safety glasses. I am actually much more concerned about having the electronic enclosure open to show the electronics. This is normally closed. The motors draw up to 3 amps, which is quite a shock. I have fuses built in, and this is normally completely enclosed.

+Tank Chain Hi Sir, Great idea to make a cover with acrylic sheets. You can still see whats happening.

+Sangyoon Kim The spindle is not controlled by Mach3...yet. I would like to do that sometime down the road. I am using MachTach www.machtach.com/ Dont confuse MachTach with Mach3, they are not related as far as I know. But it is just measures the rpm of the spindle. There is no control loop at all right now. As for the thermal questions, I am not worried about my motor getting hot. It is bolted to the aluminum frame and that will pull the heat away quite well. The whole spindle mount is acting like a heat sink and there is pleanty of air flow around the motor as well. I got side tracked on other projects and my work is in the process of buying a Haas Mini Mill. So I have stalled a little bit on this project. But I still plan on finishing it one day when. Most likely some other project will come up that will make me want to use this mill and that will motivate me to finish it.

+Tchefter Just Google (or use your preferred search engine) "backlash free coupling" and "lead screw thrust bearing" and you will get the information you are after. Its a lot of different types for sale at e.g. EBay.
