Simulated CNC Milling - Running G-Code on LinuxCNC & G0704 CNC Conversion
Now that I've jogged the axes around, I wanted to run some G-Code. I made a simple model in Fusion 360 and used the manufacturing workspace to generate the G-Code for LinuxCNC.
The Grizzly G0704 CNC conversion goes through the motions of milling the part. I didn't run the spindle, so no end-mill was used. This was just an exercise in running G-code on the new CNC mill.
Side note: The way covers are prototypes, 3D Printed using TPU. I'm redesigning them to work with limit switches, but I'm quite happy with the TPU.

1:26 - Simulation Begins
2:58 - Helical Interpolation Fast Forward Begins
3:21 - Enlarging the Hole
3:38 - Facing Operation
4:07 - X Axis Motor Motion
4:34 - Finishing Pass
5:03 - Volt and Amp Meters
5:58 - Final Operations

Grizzly G0704 CNC Conversion First Motion
zhlédnutí 2,8KPřed rokem
After working at building the system for several months, I've finally got motion from the CNC milling machine axes. Only a couple minor issues came up. The Z axis was running backwards, which was a simple fix by flipping a dip switch on the motor driver to change the motor direction. There was also a clunking noise when the Z axis would move up. Also another easy fix. I was being too conservati...
CNC Conversion - Electronics Enclosure Gets Powered On
zhlédnutí 6KPřed rokem
Finishing up the Electronics Enclosure for my Grizzly G0704 CNC conversion. This DIY CNC conversion has been a fun and educational experience so far. Using a Mesa 7I76E controller card and LinuxCNC the conversion is nearly complete. Important Note... Don't power on a servo motor system without the motors connected. Mine uses stepper motors and it's OK for my build. Another Note/Update: At 10:57...
Volt / Amp Panel Meter Installation/Mounting
zhlédnutí 671Před rokem
Installing cheap panel mount volt amp meters. They are a good value due to the cheap price, but mounting the meters is difficult due to poor design of the bezel and housing. One solution is to remove the circuit board before snapping the meter into the panel. Here's a Link to a post I made with a pics of how to wire up these volt/amp meters: czcams.com/channels/HOSNgw0wNxo6bzCCwvRPIQ.htmlcommun...
Unboxing a New Tool - PX900
zhlédnutí 852Před rokem
Unboxing a new (to me) tool that will make the CNC electronics enclosure build look and be more professional. Proper labeling of the wires and components throughout the system will save many headaches later on. This will help get the job done right the first time. I requested and received, at no cost to me, the Epson model LW-PX900 because it can print on, up to 36mm label tape. That's 1-1/2 in...
Mesa 7i76E Overview & Single Ended vs Differential Mode Signals
zhlédnutí 4,5KPřed rokem
In this video I talk about the Mesa 7i76E CNC controller card. I look at how power is applied to the logic and I/O sections, as well as single ended and differential signals for the stepper controllers. I also take a look at the 7i76E version vs the 7i76ED version which has sinking outputs. For the field inputs I talk about why it a good idea, if using proximity sensors, to select PNP type vs N...
3D Printed Parts for the CNC Electronics Enclosure
zhlédnutí 1,1KPřed rokem
By request, in this video I talk about the mounts / parts/ adapters that I created for the CNC electronics enclosure for the Grizzly G0704 CNC conversion. The five parts are: 1. Cooling Fan Mount 2. Stepper Drivers Mount 3. DB25 Mount 4. Mesa Controller Mount / Adapter 5. Relay Board Hinged Mount The last few minutes of the video shows all the parts in detail on a rotating stand if you want a c...

3D Printed Connector Panels for the CNC Electronics Enclosure
zhlédnutí 1,7KPřed rokem
In this video I look at the connector panels I 3D printed. Using 3D printed panels ensures that all the connector cutouts are properly shaped and spaced. It also makes it easy to reconfigure by printing a new, updated panel if necessary. I used a UV curing resin to infill the text. Another option is to change the 3D printer filament color for the text vs panel during printing. Sorry for the mic...
Enclosure Component Layout for G0704 CNC Conversion

Here I go over the basic layout of the parts and components in the electronics enclosure for the Grizzly G0704 CNC conversion. I will be adjusting the orientation and location of DIN Rails and connectors, but it's pretty close to what I expect it to be.

3D Printed Rotating Stand Powered By The Printer That Made It!
zhlédnutí 373Před 2 lety
Oh look, a squirrel... I got sidetracked from my CNC conversion to create a rotating stand - platform for shooting some video of objects for the enclosure. See my other videos. In this video I go through the whole process including the CAD model in Fusion 360, and talk about the G-Code which is posted below. It's the first G-Code I've done, so use it at your own risk... Though it's simplistic e...
Grizzly G0704 CNC Conversion - Mounting the Power Supplies in the Enclosure - Video #10
zhlédnutí 1,3KPřed 2 lety
In this video I begin to assemble the electronics enclosure for the G0704 milling machine CNC conversion. I create a 3D printed, hinged mount for the power supplies that power the stepper motors. Update: The VHB mounting tape has proven inadequate to hold the hinges of the power supply mount. I will be bolting the hinges in place. In hindsight I would have used two power supplies. One 48 to 50 ...
