Well, that escalated quickly!

If you can't make it work, you can definitely recover your cost by selling the electronics, they look very clean. Might even pay for your construction project.

I just brought home a 20 y.o. Techno CNC Servo Lathe, my first lathe after many different routers. It's an educational machine so the control is very simple, MFR claims it is Fanuc compatible,...

I had a Stinger X3 and had the exact same problem. One side of the table cut dead-nuts and the other made parts too wide by about 0.020". Resolution measured by a ruler was spot on and repeatable....

Still unsure what caused the wavy cut. Chalking it up to a workholding issue. Steps per inch were increased to 6400 on both controller and drives, will decrease to 3200 if I see a need.

Which...

I'm having an issue when the Y and X axis are run in tandem, as in a diagonal line or circle, I get a wavy cut. This is intermittent. Oddly the wave is synchronized between the upper and lower...

Problem solved.

I noticed that when I moved the 0-10V wire while the spindle was running, the speed would change. I have chased EMI issues all along while building this machine, so I suppose I...

0-10V wires are not twisted pair, just 16 AWG stranded primary wire. Should they be twisted?

Here’s the spindle nameplate (why do these forums always turn pics sideways??):
...

24” wire to VFD from Acorn is a pair of 16 AWG wires so I don’t think it’s a voltage drop issue. Possibly shielding?

I too suspect a parameter is out of whack but I have triple checked with what...

I’ve had my VFD running my spindle with manual speed control (panel potentiometer) for a while with no issue. I thought it would be useful to control the spindle speed using my Centroid Acorn...

I’ll leave it up to the engineers who spec the parts to decide whether they should be printed or machined. I would just like to give them the option, because I can see a significant cost savings for...

I’d like to add a 3D printer to our small shop. Our main customer uses a lot of plastics that I think could be much more efficiently printed vs. machined, and I think their tolerances would allow it....

That’s more or less what I was thinking. My first idea was to lay some straight rails under the bottom of the slab and shim between the slab and the rails until it was stable. Haven’t decided how to...

Hi folks,
I have 3 sycamore slabs about 98” long that I need to face/flatten on my 60” long CNC router. I can slide the slabs through the machine but my question is how to register them so that the...

A plain old metal turning lathe would be fine, a CNC lathe would be great. Sorry if this isn't a CNC specific question. I don't have time right now to take on a CNC conversion, but if the machine was...

Hey folks, I'm finally putting my resto-mod router to good use. I have a customer that is flooding me with RFQs, and I'm passing up a lot of good work because I don't have a lathe. I'll admit I have...

I inspected the bore as best I could with the rotor in place, saw no rust. The rotor will need a special tool to pull it, so I decided “if it ain’t broke, don’t fix it”. I tried to get a shot of...

Thanks all for the informed and well considered replies. I think it’s very interesting the way both vanes broke in almost the exact same pattern, this leads me to believe I will find a patch of rust...

Thanks Marv, that’s probably the case. There is some rust on the mating surfaces of the housing so there is probably more in the cylinder. Hope that rotor is easy to get off the shaft, it has two...

My converted Masterwood Speedy 207 has a 1.1 kW dry rotary vane vacuum pump.

The machine is practically brand new, even though it was built in 1999...long story. The pump probably has about 6...

The machine is now stable. I replaced all control wires to the Clearpath servos with stranded CAT6, preserving the +/- pairing for each signal within each twisted pair. I did not reinstall the...

Here's what I've done to mitigate the "step timing error" on the Clearpath servos:

1. Switched unsheilded VFD cable (VFD to spindle) for a shielded cable from Automation Direct. Separated cable...

I’m having the same issue, although I used 1k resistors as shown in the SDSK manual. Would changing to 10k as Bridgette suggested make a difference? OP mentioned a “bigger pull up resistor” which...

I have attached an "as built" schematic. VFD control is hardware only.

ALL 3 drives instantly fault when the spindle is started. This tells me that there might be a spike or dip in the 24V when...

Just got the 16ga shielded VFD cable installed from Automation Direct. No change. All 3 SDSK servos immediately throw a "step timing error" fault as soon as the spindle is started. VFD cable is...

I was on the fence between 16 and 14ga. Not sure what the max amperage on my spindle might be but if the voltage is 220 then it must be 10A or less. OTOH the wire run is long, I estimate 30-35'

AD...

AutomationDirect has this cable specifically engineered for VFDs. I checked out the IGUS, no kidding it's expensive! The AD stuff is about 1/3 the price.
...

Long story short, I decided to abandon the DC servos and switch to Clearpath SDSK servos on all 3 axes. Tuning the servos was challenging to say the least, and I suspect the low-resolution encoders I...

IT'S ALIVE!!

I can now jog all 3 axes via the computer. A couple gremlins have appeared:


-The Y axis doesn't stay in position, it will randomly move ~.050" in either direction at idle....

Started tuning the X and Y servos, the plots in Tuna were a mess. A couple things were wrong here (RTFM) but mainly it turns out that because the encoder is on a belt driven screw drive NOT directly...

My CAMaster CNC had quite a heavy Z-axis with a spindle and two outboard 1-3/4 HP routers. It had a pneumatic cylinder to assist the stepper with lifting the Z car.

My DIY project is lighter but...
