Programmed and machined a T-800 head from thingiverse:

T-800 Picture

Here is a finished scull video from all sides:

In the 1st op I milled the base with a 1/4-20 tapped hole right where my Z0Y0Z0 will be.

Then I mounted the base on a square fixture using the tapped hole. This way as I index the square fixture in the vise, my part Z0Y0Z0 remain in the same spot.

2nd op was the back of the scull

3rd op was the face, and the 4th and 5th were the sides

Here is a YouTube video of some of the 3rd op machining. Warning Loud Noise!

Shariff DMC2

July 10, 2021, 6:56 pm by Eldar Gerfanov (Admin)

Thinking about getting your self an affordable desktop CNC?

Check out this Shariff DMC2 designed and built by my fellow Canadian!

I wanted to purchase the first version about a year ago, but his Kickstarter campaign has ended by then and I ended up buying a used Prolight 2000 with auto tool changer.

This looks like a quite rigid, fast and a very powerful (3HP, 24k rpm) machine.

Certainly has better accuracy and power than my old heavy desktop machine with  0.001" backlash and just 1hp, 5k spindle.

Not affiliated in any way, by the way. Just looks like a great product all around.

Custom CNC Pendant Project

April 13, 2021, 12:28 am by Eldar Gerfanov (Admin)

Ever since getting my benchtop CNC running, I have not been very happy with the lack of manual control over overrides and buttons.

This DIY Engineering video gave me a great idea: build one myself.

I wanted the smooth speed and feed overrides, so I decided to not go with HID device, but instead with a full serial control paired with a custom plugin on the UCCNC side.

Here is the Fusion design of the enclosure:

And here it is 3D-Printed.
Acrylic face engraved from the back side and painted.
And all buttons and controls mounted:

All I have to do now is wire the Arduino board, program the plugin, and test it!


Here is the video of the pendant in action:


1. PCB Design

Design notes:

  • All resistors used were 10K
  • Speed and Feed potentiometers are 10K
    Their pinout goes Wiper->ground = 0%, Wiper -> +5V = 200%
  • Axis and Handwheel Increment rotary switches are 4-position and their pinout goes like this:
    Axis select 1-X, 2-Y, 3-Z, 4-A, C-Common (+5V)
    Handwheel Increment 1-0.0001, 2-0.0010, 3-0.0100, 4-0.1000, C-Common (+5V)
  • All function buttons such as Jog +/-, M1, M2, etc are sending +5V signals to the digital pins D2-D12
  • D13 digital pin is connected to a LED indicator and is used to tell the user that the Pendant is allowed to send signals to the plugin.

  • 3D-Printed Black PLA Enclosure (shown in pictures): 30$ + shipping
  • 3D-Printed Black PLA Face Plate (optional): 15$ + shipping
  • CNC Milled and Engraved unpainted (clear) acrylic Face Plate (shown in pictures): 30$ + shipping

3. Arduino Setup

  • Install the Full Firmata library onto your Arduino Nano (Or any other Ardiono that supports USB Serial Communication): imageStandardFirmata sketch used for Arduino NANO is also added to the release package
  • Please note that you might need to install Arduino USB Driver in order for your Arduino to work on the target computer!

4. UCCNC Setup

  • Download the latest LEETArduinoPendant from the releases and extract it to your PC.
  • Copy the LEETArduinoPendant.dll plugin file to the C:\UCCNC\Plugins directory!
  • Copy the Solid.Arduino.dll file from the Solid.Arduino release folder to the C:\UCCNC directory.
  • Please note that you might need to install Arduino USB Driver in order for your Arduino to work on the target computer!
  • Launch UCCNC.exe, go to Settings->Configure Plugins, and mark the LEET Arduino Pendant plugin as Enabled and Call startup
  • After everything is installed, Arduino is connected and UCCNC is running, press the "Enable" (+5v to D2-B-ENABLE ) button that will tell the plugin that the pendant is ready to send signals! D13 (LED+) will then have a continuous +3.3V signal alerting you of that!

Advanced Screen Editor for UCCNC Motion Controller Software

March 4, 2021, 7:03 pm by Eldar Gerfanov (Admin)

The job of a software developer is to solve problems.

So naturally, when I wanted to easily edit a screenset for UCCNC motion control software, I decided to create an app for that!

You can find it here:

Currently, the list of features include:

  • Selecting and aligning multiple elements at the same time
  • When multiple elements of the same kinds are selected, you can also modify their properties at once.
  • You can generate and export buttons:
  • You can add and assign pictures to buttons:
  • You can Create, Copy and Delete selected elements.
  • Images can now be loaded in any directory within Flashscreen:
  • It also has a 10-step undo button!

In all, I killed 3 weekends working on it, so perhaps, it did not save me much time, compared to doing without it.
But I also had a lot of good time figuring out how to parse a large C# config file, split it into thousands of nodes and render them on the screen.

There may be some bugs in there I didn't catch, so if you find anything weird, just let me know.

Make sure to back up your existing profile because it will override the imported file when you click "Save".


3D Printed Enclosure for Touchscreen CNC Control

February 10, 2021, 11:29 pm by Eldar Gerfanov (Admin)

Since my garage/shop has a limited workspace, I have long wanted to upgrade the big and clumsy computer I used to drive my little Prolight desktop CNC to something more elegant and convenient.

TL;DR: You can read about the printing settings and download files on Thingiverse:
Here is the shared Fusion Project:

After quite a bit of googling, and testing the UCCNC control software that i already have I decided to re-use my old Z83 mini-PC with Intel Atom processor.

Then I ordered a SunFounter 10.1" touchscreen monitor with a nice resolution of 1200x800 from amazon.

Since the display does not come with an enclosure I decided to design one myself.
A good opportunity to dust off my 3d modeling skills:

My Creality Ender 3 Pro printer does not have enough work area to print the whole enclosure in one go, so I split it into 2 pieces and printed them separately:

Using fairly aggressive printing settings and 24 hours (and one 1/3 complete failed print) later I had both parts in my hand.
Softened the joint over an electric stove and joined them together.
Then used a soldering iron to weld the seam with the same PLA plastic I used for printing.

I had some brass inserts laying around, so I used those in places where components needed to be screwed to the enclosure.
Here is the top view with the mini-pc already mounted inside.

The CPU sink on it gets rather hot, so I installed 2 30mm fans to circulate the air out of the enclosure. Powered by its own USB port.

Then simply connected the touch cable to a USB port and dropped the touchscreen assembly into the enclosure.
Fixed it with 4 screws from the backside.

Here is how the whole finished assembly looks from the back:


The thing to do next is to install it on the machine with some sort of quick-change bracket. LCD screens do not like freezing temperatures too much so I will not be leaving this one in my garage for the winter.

I am still debating over buying a pendant with a jog wheel.
Maybe I will convert an old computer mouse to work like an MPG.


Do make sure to stick around for the ATC project update!

ProLIGHT 2000 retrofit. Installing All the components.

September 11, 2020, 9:01 pm by Eldar Gerfanov (Admin)

Having done all the motor tuning and testing on the table, it was time to mount everything inside the machine enclosure.

I cut the heatsink to size enough to house four drivers, laid out some mounting holes, and drilled and tapped them M3.
Then drilled clearance holes in both the heatsink and the board and joined them with some 19mm long brass standoffs.

Drilled a hole in the enclosure for the motion controller mounting and LAN cable connection.

Then the main board containing drives and the power board and the breakout board were installed in the machine.
At this point, I realized the drive mounting scheme I chose was a mistake because it was a lot more challenging to connect the wires to the drive terminals so deep and so close to the enclosure. It helped to unscrew the main board, pull it out a little, connect the wires and only then push it back in and screw it to the wall of the enclosure.

Traced all the black cable going to the fuses and found which ones control the spindle and which ones go to the appliance plugs.
By fiddling with the controls on the front of the machine, identified all the wires and their functionality.

The Gecko G320X drives use the same (ERR/RES) pin controlling the drive fault reset and the error status.
When the drive is at fault (every time you startup or when the motor loses too many counts), it has a ground voltage of 0. If you pass +5v, it will reset the fault and enable the drive.

So I had to re-use the red cycle stop button to pul it to +5V when the machine is started. To sense the drive fault and stop the machine I used pin 12 (pull-down) on the C11G BOB. So when any of the drives pull ERR/RES to ground, the C11G board and mach4 react to it like an E-STOP.

The motors mounted back, and the encoder wires soldered directly to the data cable wires of the same colors. For that, I cut off the bulky DB-25 connectors.

Pay attention to the property belt tensioning. According to the manufacturer, the belt should sag a maximum of 1mm under the pressure of about 3 pounds applied at its middle point.

With everything connected, it is time to test the machine. See how it homes and runs!

ProLIGHT 2000 retrofit!

August 20, 2020, 7:20 am by Eldar Gerfanov (Admin)

I have been hunting for a very rigid but small machine for the last year or so.

And when I finally found one for sale on an auction in Minnesota, I could not pass.

Now the machine is in my garage.

It is a surprisingly heavy machine with a solid epoxy granite frame.

The features are as follows:

  • 1.5HP 5000 RPM spindle
  • Closed loop servos on all axes
  • Power draw bar and a rack tool changer assembly

I built a table with casters for it and upon plugging it to a computer it turned out that.... It's dead!

The proprietary Animatics control in the back is not working, which means 95% of all electronics in the back must be replaced.

I was actually almost hoping for that because the original software is DOS-only. It is hardly convenient to work with it.

I want it to work under mach or LinuxCNC

So I ordered the required parts online and when all of them are here, I will start the retrofit process.

I will be documenting my process in comments.

Wish me luck!
