Chris' Grizzly G0704 Acorn Update
Posted: Thu Jan 21, 2021 3:38 pm
Hello,
I converted my G0704 to CNC In November 2012. I've been using Mach3 with the Mach Standard Mill screen set. The mill has been through several iterations but I've always been a bit disappointed with the stability of Mach3. That combined with the inaccuracy of my home switches created a pretty frustrating system to use. Mach3 would start acting up (usually right in the middle of a job), so I'd have to restart the PC, the controller and the software, rehome the machine and then relocate the origin of the job. I've been looking at a controller upgrade for quite a while and finally purchased an Acorn.
I have the following hardware on the machine:
Grizzly G0704 mill
CNC Fusion's Premium Conversion Kit
From Automation Technology:
3 x KL-5056D Digital Bipolar Stepper Motor Driver-32 bit DSP Based
3 x NEMA23 570oz/in 5A 3/8” Dual Shaft Stepper Motor (KL23H2100-50-4B)
KL 48VDC/12.5A Switching CNC Power Supply
Mean Well LRS-50-24 24V Switching Power Supply for inputs, fans, relays
From Automation Direct:
MTRP-002-3BD36 2hp, 56C frame, 3600rpm motor
WEG Electric CFW300 series vector drive
Metrol CS067B-L Precision Touch 5 Micron Accuracy Limit Switches
Intel NUC NUC8i5BEHS system (i5, 16GB RAM, 256GB SSD)
ViewSonic TD2230 22 Inch Touch Screen IPS Monitor
Home Brewed Belt Drive Conversion
Home Brewed Fogless Coolant Misting System
Home Brewed 1010 T Slot Enclosure
Manual Oiling System
Chinese Tool Setter from eBay
Kurt DX-4 Vise
The enclosure with monitor mount, keyboard tray, and tool tray. 1/4" Lexan front and left side panels. Coroplast rear and right side panels.
The 2hp motor and belt drive.
The controller layout so far. Clockwise starting at the top left corner. 220V power relay, one of the two 24v PSUs, VFD, 110V power relay, 48V PSU (110V relay and 48V PSU under the electronics tray), 110V terminal strip, 3x stepper drivers, 220v power relay.
Window cut in the enclosure faceplate for the VFD.
