Very nice work for sure. What size steppers are you using? Also if you could share details on your limit switches I would appreciate that.

Thanks for the updates, I'm planning on converting mine. Are you planning flood/mist cooling?

You should move in one direction only to set steps per inch. For example move X +1, zero dro and move X+2 and then measure +/-2.XXX, this way you don't put any backlash into the measurement. If...

what spindle motor will you be using?

The stock cabinet is about as flimsy as it gets, same for putting it on a tool box. I made mine wide and filled it with sand, the cross members are 1.5" .25" square tubing and the rest is...

I have the 1100w version, for 200 I'd still avoid it. It works ok but I had to under drive it by 20% to minimize rpm changes, ramp rate is very slow. Save the $ for a VFD and be done with it.

If you switch to flood the outer ones will fill up with coolant pretty quick, maybe consider replacing the outer two with trays that divert everything to the middle one. My swarf drawer has a similar...

I use Danco 88822 kitchen sink strainers in my swarf drawer over the drain. Place it upside down and let the swarf build up on it, a couple of magnets will hold it in place just fine.

Since the bottom is flat could you cut a slot on one side? I would elevate the mill a bit then and slightly tilt the stand. You would be able to wash everything to the drawer then, I wash it down...

Thanks, I actually cut out the flat bottom part when I repainted the base, like you said the flat part collects it and it piles up fast.

I did mine like that, If you can modify the pan to put a swarf drawer I would do so and make it a large one. You can get stainless restaurant pans very inexpensively. Mine is 12x14x2 and...

I used those on mine. They work fine, just takes a little time if you have to use a wrench. I rarely move mine so no big deal.

I use the manual 1 shot. The one I have pumps from both sides, I set Z up on one side with a quality check valve to keep it all from draining back down.

Topsflo? They do move a good big of water, did you test it with 6-8' of head?

I did my pan like that as well, it has worked very well. I used a single stage epoxy paint on it and the coolant removed it, it was very time consuming mistake. You may want to have it epoxy powder...

sanity check: you did wire the dir/start stop/enable on the bldc controller correct? I ran the pwm from the C10 directly to the bldc controller, it has a pwm input so I didn't bother with the C41

I purchased a 6" grizzly with my mill, it's junk. The jaw lift is terrible and the unprotected screw gets jammed up with chips....I use it on the welding table now :D

Glacern recently lowered their prices on 5 and 6" vises. I think they just sent out a coupon as well.

I'd like to hear more about Trim 585, Koolmist 77 did a fine job of removing the paint from my enclosure.

The supports are 1.5" square with a .25" wall, the bosses were welded in and both were milled flat where the base sits. The frame is filled with sand and old coal slag from the basting cabinet.

I did mine out of sheet metal. The mill is suspended over it and with a 4x6 hole it's easy to wash it all down in to the chip pan.

mine was 600, vfd didn't meet the power requirements. At some point you have to look at what this is, a benchtop tiny mill. For what's in it I can live with one more go round........you act like...

The 2200W motor should be on 220, that's more than 18A on a 120 circuit if you have it turned up. I have 220 close but my driver box isn't all that easy so I'll get to that when I have less going...

It's basically worthless at low rpm. But their test uses a rougher and if it was 1:1 their chart shows approx 850W of power at the rpm I ran it. I may run 220 over to the supply to see how it...

I'm still figuring this thing out but this is the 1100W motor 1:1, 3800rpm .250"doc, 16ipm, 50% stepover, 1/4" 4 flute hss

Yes I'm hooked up directly from a c10 bob to the pwm control. I supplied the board with +5 from another supply and common ground from the bob. I also grounded out the s/p input otherwise...

The connector next to the PWM input has an rpm output frequency(Fout). Just input that to your bob, assign the pin to the INDEX on your inputs as an active low. Then put a 2 in your pulley ratio...

I was able to take Fout signal to an index input and set the pulley ratio to 1:2 and it's pretty close to actual rpm.
