My intent is to build a new base, saddle and possibly column. The column is what would likely be the tipping point of selling the G0704 and hitting auction sites…..
EG would only be cast around the...

I’ll draw it up and get a quote, I’m curious to know what a solid piece cut to shape would cost….

I have a unique position where I can actually heat treat. I have a kiln that I have done 14hr burnouts of lost form molds for casting (it has a ramp controller so annealing I could be done), so if...

I have been running my CNC G0704 since 2016. It has served me very well. It’s a very basic set up with the stock dovetails and stock y travels.

I’m falling down the rabbit hole on upgrading it. ...

Dredging up an old post because I can’t find a good definitive solution to the ball screw bearing mounts that seem to be coming back for me.

I like Arizona Video’s kits, if I didn’t already have...

I bought those coupler Jim listed above:

Mounted up great, seam a bit stiffer than the jaw type...

I am trying to find a good coupler for a NEMA 23 stepper.
I have had bad luck with the "spiral" aluminum couplers that were shipped with the motors from automation technologies.
The motors are...

I’m very curious about the oil drip. Please tell me more.

I have seen a lot of bearing carnage too, I’m a millwright in a sawmill, last night at 3am we got a call because a conveyor stopped...

Coolant and some chips got into my spindle bearings on my G0704.

I am shocked I haven’t heard of this before after taking apart my spindle for an autopsy of the bearings.
I get that there can’t...

The stock drawbar is all you will need, just add the bellville washers. I did it and it works but watch out for “pullout” , if you load up the tool the clamping pressure might not be enough. I had...

I agree, don’t bother with putting steppers (or servos) on lead screws.
You likely saved a ton of cash on tooling when you bought the mill so you are already up.
I used a lot from Automation...

That looks EXACTLY like what Benchtop precision was selling, I’m sure it’s even the same pictures.....

Curious

The stock quill drive on these mills is trash. I want to keep the quill and have...

It’s looking like Benchtop Precision is closed down....
The website isn’t opening now.
Does anyone have any news?

Reviving an old thread.....
How would I cut these grooves by hand, I don’t have a second CNC set up....

I want to add an oil system to my G0704.
Without a second mill to machine the grooves in the saddle I am considering cutting them with a dremel.......

What is the best way to do this?

John,
Thank you!
I switched the jumper to "pull-up" and the 5vlt NPN proximity sensors work perfectly. No added resistors.
I did find a diagram on the probe set up in the C-10 manual. With the...

I dont think a repair is worth the effort, the benefits of a belt drive conversion are well worth the effort. It can greatly reduce the vibration at higher speeds.

With a belt drive you can setup...

Thank you for the reply.
Will I have to add any components? It appears that all components to the left of the dashed line are on the BOB.

Currently my jumper is set to pull down.

How is a...

I am having trouble with the voltage dropping on my proximity switches.
I purchased some 5vlt prox switches, when they aren’t connected to my C-10 bob the switch behaves well, provides 5vlts until...

The belt drive kit on Benchtop Precision’s site has been in unavailable
for sometime, and now the link won’t open...
Have these kits disappeared?
Have the demand for them dried up?

Car batteries would be a great solution, I think.
Heads up to anyone using a power supply for induction heaters:
A switching power supply ramps up slowly, this will blow up the mosfets on the...

This hits the nail on the head. The trick to removal is fast heat.
I’m a millwright and often deal with shrink fit hubs and shafts. If the part with the hole can be heated fast enough then the...

Interesting that this is a critical piece of the puzzle and there isn't an outpouring of support.
I bought a "kit"!from automation technologies.
The electronics are EXCELLENT, nice box,...

With the cap spinning with the pulley, quill and spindle, the quill could rest against it. I'm guessing what you listed are the reasons Hoss has the version 2 MAD block fold down and out of the way....

Maybe not the right place for this post but I would like some feed back on an idea/adaptation of the MAD/ manual power draw bar.....
I would like to mill a shaft and pulley assembly for the belt...

I stumbled across CNC cookbook and I am blown away by the approach and the content of the training modules.

I know most of the users here are well versed in G Code and would see this as...

I know that the spindle DRO that comes stock on the G0704 is likely long forgotten for many on this site but I really found it handy, particularly for quickly counter boring for socket head cap...

I have a brand new G0704. I'm a total newb.... I have done some very limited milling and lathe work in trade school (I'm a millwright apprentice)

I have a project that requires notching 1" EMT...
