Its been a while since my last post and understandably I've received several emails asking if I stopped making the BF20 kit. For those interested I'm still making them but right now I'm just to busy...

No its not the same. The one I got is an upgrade prototype on the original model. It has lots of torque and much quicker to adjust to changing loads but after testing the overload protection by...

Ive been using the 1100 motor on my mill for a few months now. The main problem with it is lack of torque at speeds below 1500rpm and and it does a poor job at maintaining constant speed at different...

I'm using a Little Giant pump I found at a local hardware store, its not great but it works....

Thanks Pete.

Yes that's a home made screen set for 1024x1280 resolution. No touch-screen, yet :) The shuttle pro is ok, not great and a little over priced, and I use it often. The biggest...

Its been a while since I posted so here is a quick update.

I think my X2 conversion is finally done... or at least its very close. Not much of the original mill left and I probably could have...

I'm not sure why I built mine, it just sort of happened. I initially wanted a small manual mill to make parts for my RC hobby but the machine quickly became the hobby. Then I stumbled onto HOSS's...

My enclosure is completely closed and yes it gets warm in there but not so much its going to damage anything. I plan to add a fan to it though to keep moisture out.

No, its all here somewhere. Haven´t had time to set up a site yet.

X: Vel: 160IPM, Accel: 30
Y: Vel: 160IPM, Accel: 30
Z: Vel: 130IPM, Accel: 20

I can now cut at 30ipm, 0.1" DOC versus 10ipm with the stock motor. I'm also using better cutters now than before so that has some effect also.

Yes that's the one and yes you will need to replace the whole drive system. I used these pulleys and belts from sdp-si.com.

I tried both, with and without Mach3. It does not run slow but could do a better job maintaining speed under varying loads and it should be adjustable somehow. Then, again given its price its not so...

I have the 1100w motor on a X2 and I agree its very slow on recovery under varying load conditions, I really would like that fixed and be adjustable somehow. Over all though its better than the 1.5...

I finally found time to install the 1100w brushless motor from Keling on the X2. It works great, although I find the speed regulation could be better. Next up is to finish the spindle pivot/spacer...

Thanks for the heads up, to bad I bought this table a few months ago. Shipping was almost as expensive as the table assembly :) but its been worth it.

I found the motor dimensions here

The 1100W motor will be a good fit for the X2, if its the 92mm size, with some...

My next task is to get one of these.

Thank you Chris for posting this. Very informative and answered all my questions. I will order one of the 1.1KW motor kit soon for my mill. I've been experimenting with a 1KW treadmill DC motor and...

This is the package Scott and I put together and used on his, and one other, mill. John at Keling was kind enough to add it to their site so I, and others, could easily tell people where to get the...

I will get the BOM made and post the plans as soon as I find time to do so. Its crazy busy these days.

Thanks mrcodewiz.

Its not that hard to make, just takes time and patience. The epoxy paint takes about a week to dry properly and I allowed 3-4 days between cotes, then waited another week before...

Its all 3/4" and 1/2" birch plywood, 4x4 studs for legs, 2x6 for the table top, aka Scott's design. EZ-bed liner, 8 spray cans and Armor Coat Epoxy Garage Floor Coating. I can't really recommend the...

Thanks for the compliments guys, what a good way to start the week :)
I'll post some more details tonight when I get home from work.

I just got my mill back up running in its new home. I´we been working on this on and off for a few weeks now and its still missing doors. The base and top are all wooden, coated with bed-liner on the...

yes thats the Stirling belt drive kit and I get around 5500 rpm max in high, never use low anymore. I'm quite happy with it, but as stated before I am not sure about cooling, or lack there...

Thanks for clearing that up Jeff.

By inserting the bronze bushing, that is on the stock Z lead screw, between the thrust bearing and the screw you can probably use the motor standoffs. I should make them longer though. Thanks for the...

I've been away the last week or so and just noticed this thread.

I am afraid you have to take the ball nut off to insert the screw. For those with a rear mounted stepper the screw can be installed...

I'm using KBIC 120 with a 1HP power resistor, rated up to 6A continuous load without the extra heatsink, 12A with heatsink. I don't think the X2 will handle much more than 6A load anyway. I should...
