I have finally come to the conclusion that my BF20 needs a new heart. I have purchased the 770 motor and the SK VFD. I have bought many things from Tormach over the years and thought this was a safe...

I use a simple Axicom D2n for about $0.60
Just used a shorting 3.5mm jack that cost about $1

Yes it can be done for super cheap

Oh I most certainly have had. Issues with the c6. Plus if you read the original post, I have had doa BOB's (plural) and issues with a MPG. Had all sorts of colorful words for the first month in the...

Good thoughts Gary, easy one first. Us Canadians don't wear shoes in the house, so my shop she's stay in the garage. Most of the chips cam in via my clothes or hair. I don't mind stripping for the...

Thanks for the compliment. The main reason is to have full control via Mach3 if I have a job that needs reversing. I do run CCW for some boring operations and u have some left hand taps I use...

Thanks guys, Yeah the gopro is hopeless for this kind of thing, should have used my phone sorry about the fish eye.
I am in Cochrane Alberta, relatively speaking not that far from you. Need some...

I hope to sort out my festering problem with stalling motors. I made this video to help describe what I have going on, and if I in fact have a "problem" or if my machine is just at the peak of its...

Its funny now that I look back on the purchase of the machine, I always knew it would be a CNC one day. For 3 years I turned the handles and made some things I am very proud of. To be honest some of...

As the title asks. What do you do with your Benchtop CNC?

Seems that I am about 50/50 right now as my machine has only been converted since the end of Feb. Seems I spend an equal amount of time...

Tested out the CW/CCW switching on a part last night. Works 100%!!! Love it now I dont have to manually change rotation direction. Next up will be research to automatically change from High to Low...

Find a UPS that can handle the entire machine load for say 5 min. You could easily wire in a relay that would initiate a program pause on power failure. With a couple minutes of UPS it gives you time...

Anyone have some good sources for single point tooling? I found Micro 100 and the prices are reasonable. What are you doing and what sizes are you finding the most useful? I do allot of metric from...

Edit:
Figured out how to do it with HSMEXPRESS. Setup a bore operation. Made a tool with the diameter of the cutter. Made the holes in the model the major diameter of the hole I am threading. I set...

have to ponder that aspect once I get my head around more of the functions of the CNC.

I successfully made some thread milling holes, turned out well -although I made a mess of the tool and the...

Great stuff Hoss, thanks. How did you change the configuration in Mach or your CAM program to do the horizontal threading? Trying to get my head around that one.

I actually have a 60deg v-slot cutter and I will have to give this a shot for external, unfortunately it is a 3/8 diam tool and I am needing to do bout 50+ M10 1.5 holes. Will look for info on how to...

The BF20 CNC is the bees knees, but without a servo like Hoss has or a lathe to make the stepper motor tapping setup he has for the X2 I would like to find some options. Seen the compression/Tension...

Drains are plumbed and tested, All good. Bought some coolant from a local Machine shop. The guys were nice enough to sell me a 4L jug for $20. Other than a couple bolt holes in the drip tray (and...

Here is one for you, Went to a reputable shop in my town, asked the machinist if I could buy some coolant. Sure he says, let me go check what I have (see if he as any to spare). Comes back and says...

Almost done. Got the doors on and need to finish up the "track" for the doors. A little more lipstick and makeup for the exterior thinking of a nice coat of primer after a good sanding.
Drain to be...

You did machine the mount correct? Will need to think about how I can make that part somehow.

So Hoss where did you buy your Ball nuts? I have your DVD and did not see it. You listed the E-Bay seller but those kits all have a different style nut than the one you have shown.
I have decided...

The plugs will not be left as is. The cover will be a waterproof box, plus a removable cover for the cables as well as the plugs. I am quite a ways away from turning on the flood coolant.

The...

In dire need of an enclosure for many reasons. The latest reason was the move to flood cooling, Next on the list was the added benefit of keeping swarf under control. Third was to make my shop a...

Thank you everyone for your contribution. I have plans well in place to build an enclosure and go to full flood coolant. I have another post on the go with suggestions to coolant options. My machine...

What concentration do you mix for flood coolant Hoss? How do you maintain the %? Refractometer or Ph tests?

I mostly mill 6061, Some Mild steel and Brass. As a hobby I don't imagine I will use copious quantity's. A local supplier has Oemeta and recommended the Novamet 900 But at $155 CDN for a 5gal pail it...
