I had a quote for the above for output to a hass lathe and vf2ss and it was nearly 30G. Welcome to Australia.

Has anyone tried a 7176 Step IO and 5I25 with the VSDXE yet?
Running EMC2 of course. It seems to be a far easier way to go.

Not really. Not sure to be honest.
I know Granite has told me before that these work so I was just going this path.

I thought I could use Renco quadrature differential encoders.
As long as they were incremental the VSD would determin the commutation required.

Are there any further break out boards I require to...

Ive had a lot of success with a large scratch build CNC lathe I built sometime ago. Ive decided to build a bigger CNC center lathe using a large center lathe as the base.

Ive got some left over...

Does anyone have or nor the http link for this software.
Ive relaced the batteries to fix my first problem and now of course need to restore the CMOS settings.

The 5v USB ports only have a limited amount of current. They become quite unstable on even 1 encoder withe decent pulse rates and can pretty much drive a single port to its current limit. Mach3 / the...

I had a lot of different random faults...under voltage being one of them.

I went through the machine thinking it was noise , motors, encoders you name it. In the end I put a powered USB hub in and...

I can pretty much tell you exactly what your problem is....

I had a similar setup try the following.

Get a powered USB hub
Connect the VSD EPI and the smooth stepper into it.

All your...

I ended up with 4 x 5S 3000 RPM motors. Should do the trick...will get my lathe rapids upto about 25m / min which I will be standing in the car park to watch :)

Will post some pictures tomorrow of...

I think I overlooked one slight issue.

Whats the dimensions of the motor 5s and the 10 s...could anyone help me or point me int he direction for that one. Ive googled about every combination of...

Thanks 10 S it is then.....that will bring the lathe upto some decent speeds and get rid of the gears finally.

Can anyone confirm if this motor will work?

Fanuc Model 10S

I had 2 control techniques that were resolver AC motors that I replaced with Renco encoders but the things just wouldnt run. So im a little gun shy now leaving the world of DC. The other option is i...

These are the other two motor options....

FANUC A06B-0315-B08-7008 AC SERVO MOTOR
TORQUE (STALL) 12NM
AMP (STALL) 7.6 A
RPM 3000
PHASE 3
150 VOLTS

DO you know which Fanuc AC motors can run with the VSDE.
I tried some Control Techniques which did not work even after I replaced the encoders.

Im running some 750W DC servo motors right now but...

Just encase i wasnt clear about the kind of runaway when homing this isint the full scale runaway you would see when you drop the encoder out the back of your motor. This runaway is at the same speed...

Im having a weird problem although making progress.

I have a USB smooth stepper pumping out to VSD 4 port BOB and then the two VSD-E boards.

When I set home from within mach3 90% of the time it...

I finally got the machine going with DC 6 pole motors.
It is moving well and is repeating on my dial guage within 0.001mm after 100 meters of left right movement and 50 meters of Z axis movement. so...

As long as you use a real time kernel and then compile on top of that you could communicate RT just fine.

Telco industry use real time linux kernels all the time with sound DSP equipment for...

Ive been using Solidcam for a while now and not having a lot of luck with just one section.

I have a 4 axis mill and need to out put code for it. (Centroid)

Creating 3 axis G code is...

I have changed the enoders to a Renco andcoder 25 serries.

The motor is now spinning in the test with an error again.

It suspects the motor to be a 4 pole count and is again turning 2615 counts...

Its about 1.8m high...2M across.

Hollow constuction back filled with sika granite mix for weight and dampening.

4 axis. Turn mill to be more precise.

Tried testint , it thinks the motor is a 4 pole and tells me there 2630 encoder counts.

I can get you remote access into the machine and GDtool if you like.
I even have a camera setup on it.
...

On the subject of hall sensors it would seem some of those renco encoders provide that. Would it be worth getting one of those?

If not is ther eanother one that makes a decent one that would be...

The axis that im having the main issue with is the Z axis on a lathe I have built. it is a large lathe and the Z axis is weight offset by a pnematic ram. It also a 24vdc brake.

Thanks again for...

Thanks for the heads up.
What configuration options did you use on the right hand side of the website?

Ive basically wasted a week with scopes tearing my hear out and a lot of wires...I cant...

Have you got an encoder that you recommend.

I played about with that command.

Sometimes I get what looks to b3 a fw rotations (quite quick)
Other times I get a 1/4 rotation in any direction, other times I get a half rotation in any...

When I issue rotation commands from mach3 I watch the encoder counts in GDTOOL it manages to make it to around 8500 counts in either direction before it starts to stutter.
As long as i stay between...
