I washed the housing out real well and re-assembled. It seems to run quietly and happily without the grease, so that's how I'll leave it. Best explanation I've heard yet is that the fan is sucking...

I have a Sabre 500 which I recently bought, and it's FILTHY. I'm cleaning it up during my retrofit, and I came across something odd.

The red cap on top of the spindle motor contains a...

I'm doing a LinuxCNC retrofit. Keeping the stock Fanuc model 5 motors, which drives I use is sort of up in the air; I have some parker gemini drives but it turns out they are less useful than I'd...

I'm retrofitting a Sabre 500, and all of the original control parts (850sx control, io rack, fanuc 3 axis servo drive, fanuc spindle drive) are working and available. If anyone needs control parts,...

Hi folks,

I'm trying to set up these Fanuc servos to run on Parker Gemini drives, and I can't find details on the motor to configure the drives. Does anyone have a datasheet or info on these?

update: it does seem to fire from the machine interface, but not from the internal connections which previously fired the hand torch.

I have a CPC connector on order for the machine interface;...

I call upon the wise and powerful hypertherm sage, jimcolt!

I have a pmax45 that I've been running on my cnc table with the hand torch for awhile.

I'm doing mechanical upgrades on the table,...

Ray,

I understand you are in the business of selling complete machines, but do you happily sell your 'spares' to folks who would prefer building their own motion?

I've been considering putting...

I ordered the SC 3/4hp motor, mostly because it's soooo cheap. I'll see how it works out.

I bought two from WT; one went on my 5C chuck, and I have a spare. Considering that the lathe came with two chucks with backplates, I figure four plates total is enough to handle whatever I may need...

I'll have to measure the motor on the g0704 tonight.

The motor on the G0604 is a D80 frame; I put a leeson D80 motor on it, and the D80 motors are WAY bigger than the stock G0704 motor.

Are those the same flange dimensions? The 3/4hp motor is listed as D71C

I've seen a lot of people talking about treadmill motors and other DC motors, but does anyone have experience with a 3 phase 230V motor that works well physically on this mill? I believe it's a...

I think this is the one I bought:

Back Plates for 11 in. Lathes (WT)

Griz wants $70 for theirs, WT wants $40. For me, that was worth the turning hassle.

same as anything else... use a DTI mounted in the spindle and sweep in a test bar in the chuck (or between centers) to align the lathe spindle axis perpendicular to the spindle axis. Use an edge...

I originally deepened and widened the carriage for clearance. When I went to mount everything, I discovered that the V way pokes through into where I had intended the ballnut to run, so I had to...

michael,

I was running it last night on the 720rpm pulley, which I believe is a 2:1 reduction. It's an 1800rpm motor, 1725 with slip, so if I run it at a range of 30-120hz, I should get...

I got the motor sorted out. 3 phase wiring is complicated! The motor's box cover has a diagram inside with four different wiring setups, marked Low/High voltage and NEMA/IEC. It was wired for high...

Honestly, for hand work a good old mill file makes short work of breaking edges, and the price is right!

I haven't been able to work with it all wkd as I am in Pittsburgh for the NRA convention.

It's the leeson 1hp iec motor and 1hp teco vfd. I set the max freq to 120hz, and it won't even turn the...

I got my motor and VFD today, and got them installed. No computer interface to the VFD yet.


First impressions are that the motor doesn't seem to have much torque, even at full speed. I haven't...

EMC is definitely more flexible. Plus, it'd be pretty rough trying to get steppers and encoders wired up via parport for mach3.

When I get my stepper encoders in, I'll be using two stepgens,...

That's the direction that I'm headed as well. I have encoders on order from digikey.

I dunno how to do it i mach, I'm using EMC2 for this machine. EMC2 handles switch + encoder homing pretty...

tefzel! I love tefzel!

Schmitt triggers made a big difference. Now my homing is accurate to within about 0.002". I turned a couple diameters, homing in between, and they were as bad as 0.003" under diameter or 0.001"...

if you're feeding way too slowly, the cutter's just rubbing against the cut walls, dulling the teeth and generating heat. Turn down the spindle RPM or turn up the feedrate. The closer you get to...

that's the idea. Frankly, I truly hope it helps, because I don't want to have to re-think my homing

yeah, I have come to the same conclusion talking to some folks. I have some schmitt triggers that I'm going to use and see how that works out.

Vibration may well be an issue, as these little...

I think the more appropriate axiom here might be:

Build a man a fire, and he's warm for the rest of the day
Light a man on fire, and he's warm for the rest of his life

So, i fitted optointerruptor home switches on it, but they suck. I need at least the X axis to be repeatable to a pretty high degree of precision, because all my tool offsets are based on where the...
