DIY CNC 013 - Configuration & Basic Testing

- čas přidán 16. 06. 2024
- Welcome back for another update of my DIY CNC build series. Today, I'll bring you up to speed with everything I’ve been up to over the past 3-4 weeks. I took some time between this update and the last to familiarize myself with the machine and build trust in its performance capabilities.
In this update, I'll showcase the brand-new baseboard and spoil board. We won’t be surfacing the spoil board in this video; that will come in the next update when we start conducting some real test cuts. I'll then demonstrate how I created the extension cable for the motors and proximity sensors, designing them for quick-disconnect from the control unit. Additionally, I'll show you how I installed the NEMA 23 motors and discuss the advantages and disadvantages of various couplers I've tried. Following this, I'll give a live demo of the Auto-homing process for the machine.
Next, I'll provide a demo of the spindle water pump and explain how I plumbed it in, running it through corrugated tubing for protection along with the power to the spindle. I'll also discuss how I configured the spindle to be controlled via the Mach3 software. Although I couldn't achieve speed control, I managed to enable clockwise and counterclockwise control, including start/stop and spindle disable functions. I'll give a Mach3 software demo, explaining how I configured the ports and pins for successful spindle operation. Additionally, I'll demonstrate the relay board and wiring from the Mach 3 breakout board. I'll also show you how to program your VFD to use external pins for control rather than the onboard front display controls. Another crucial aspect I'll cover is configuring the DIP switches on stepper drivers to set pulses per revolution, explaining the trade-off between speed and accuracy for NEMA motors.
Finally, I'll demonstrate the machine running some G-code. I've decided to run the ‘roadrunner’ G-code that comes pre-built with Mach3. While simple, it's a safe option for experimenting with your machine for the first time.
In the next video, I'll focus on further calibration of the machine and surfacing the spoil board for the first time. Then, we'll dive into some real cuts! I'm looking forward to having you back here again. Take it easy!

I’m impressed I learned so much from all your videos. Thank you very much! I’m going to build my own machine now.
Good for you. Have fun.
Observation, when you open the Windows for fresh air the horizontal blinds will move away from the window and may get caught by the motorized horizontal gantry. Also a bungee from above to suspend the cabling
Thank you. Yes, the bungee is a must. As for the windows, they can't physcially open so I should be okay :)
شكرا
I’m really impressed with your build, the quality and effort is premium! Puts my little home built 3030 machine to shame.
I am curious as to why you selected Mach 3? The parallel port requirements are a non starter for me, same with Linux CNC.
I’m running grblHAL on an MKS DLC32 ATM, but I’m currently looking for something better. The E5X MCS T4.1 looks really good, but is not cheap, although at least I won’t need to buy separate software license.
Inspire me a lot thank you for all of your effort.
Even iam also building a CNC machine your videos helped me lot .
Can you please post the CNC drawing file(fusion 360 file)
Hi. When you are jogging the X axis with the Right keyboard key the carriage go to the left. It seems wrong to me !!! You need to refer from the front of machine, not from the back.
@41:26 who whispers "Hi"?
Bro, those axis are very loud and do not sound good. Check the alignment before damage happens.
Also, install some drag chains.
It's not that loud, the camera audio might make it seem louder than it actually is. The hollow table amplifies a lot of the motor sound too. The linear rail motion is very smooth, as seen during the build process. I don't want any drag chains for my build, I'm suspending the Z axis cables and the others are going into the corrugated tubes. I hadn't yet done that when I filmed this video
how much would you sell this for? or at least value it for?
I will be updating the BOM spreadsheet very soon. All in it will be less than £3000 GBP
those couplers you took off are waaaaaay better then the sping coil couplers you put on.. they WILL break and you will ruin a workpiece or bend a ball screw.. be prepared. Just saying.. the X axis coupler is decent.
I agree, I sent them back because I had two break quickly. I have now replaced both Y-Axis coiuplers with the same coupler I showed for the X-Axis in this video. They seem much better!
can you send me control wiring diagram
I don't have a wiring diagram yet, but I did make a dedicated video explaining how to wire the NEMA motors and proximity sensors, and how they interface to Mach3. Check out 010 in this series.
