Great videos, interesting that to do all this you need many more machines. I have most of them but most looking to convert don’t. Were you building in a 5th axis for the head? I learned on a Bridgeport knee and rotation of the head was easy, little more complicated on the Grizzly.
It's very nice conversion and interessting modification. may i know how long travel did you get in the Y axis with your extention ? did you get more travel in the front too? well i just strat my conversion with my BF20 and i think i will make the same extention. thanks for sharing.
Thanks. In my opinion its a good value. If you like this sort of thing that is. I built my CNC router from scratch and was contemplating doing the same for a mill. But for the low cost of the G0704, It just made sense to go this route. Still working on more modifications. enclosure, flood coolant, and fixture plate already done. working on power draw bar now then spindle bearing upgrade with belt conversion with a 3 hp motor will be to come.
I did not buy a conversion kit. I made most all the components myself, but I know there are some kits out there. Try here: www.automationtechnologiesinc.com/products-page/g0704-kit/g0704cnc
Pretty happy with it so far. I either bought or made all the components separately. There is about $700-$800 in just the cnc conversion which included the electronics with a smooth stepper.
Hi Man, good job, I am now in the process of doing the same, eveything is pretty much clear but I didn't get the reason for the spacer between the bed and the column and the one behind the head. could you explain pls? Don't they introduce more vibrations to the whole mill? thanks Fabio
Fabio, I extended out the y axis to have more travel. Y is just under 10" of travel now. Adding the spacers for the column allow me to take advantage of the entire travel of the Y axis.
Hello I'm about to to do the same conversion and i have several questions is it better to buy Nema 43 instead of Nema 23? considering I pretend to machine Stainless steel on mi G704... also.. is it possible? do you have the cads for the spacers and the bearing and ballscrew info?? Thanks in advance! David
I have found 570 in-oz NEMA 23's to be adequate. Maybe a 43 on the Z would be better. And stainless is not a problem. RoboCNC has cad files available here: www.robocnc.nl/?page_id=3574 click on each axis and it will take you downloadable files.
Thank you for your quick answer btw regarding the y axis did you use a larger ballscrew than the one used by robocnc? noob question Sorry i'm just putting together all the stuff i need Regards David :)
Loved the music themes on your videos!
Nice setup there

Thanks. I think I got about 9-1/2" of travel on the Y axis. X and Z are stock.
is the go704 a good machine for the diy ,looking into geting one this is a great job youve done with the conversion

think i go buy the g0704 are the conversion kits expensive to get it running completly whos sells them

Hey William, are you happy with how you designed all of the parts for the CNC conversion? also how much did the entire kit end up costing you?

I used 1605 for both the x and y. And used a 2005 for the Z axis. I think it is the same as Marcel used.
