Sure it will be fine.    Just be careful setting your pressure!   


I need to start thinking of making a new tool turret for the Hardinge.   Got some material (EN24T) in to make the Curvic couplings, so thats a start!

schedule 80 tube should be available.

Nothing to bump!  The machine runs day in day out making parts.

It's been such a long time since I have been inside a chnc. 

Have you managed to decode the turret ecoder with the cubloc?  I seem to recall it's output is bcd.

Can you operate the air valves to lift turret, spin it and engage the turret stop?

If you can it's all down to getting the timing right.

I'm here just rather busy.

I posted all the code in my HXL thread.  The CHNC turret is completely different though and a much harder animal to control.  

Basically all I'm doing is using a holding register to hold current tool station.   The Cubloc runs a basic loop which looks to see if a new station has been requested and operates the air valves to achieve this.

The CHNC turret is bi-directional and operates with an air motor.  My code is not going to help you really as my HXL turret is an indexing type and single direction.

You basically have to monitor the encoder and fire the stop solenoid in sufficient time to stop the turret on the CHNC.

You might want to find this guy

I just googled "cubloc chnc" and that came up.

Mark

Shame, but maybe offer it on here?  or the EMC guys.   The HXL is really a good machine and someone should want it. 

Not many machines capable of the same accuracy for little money day in day out.

I'd be interested in a Parts catcher if yours has one!

Well the machine has been running about a year now, and I been fairly happy with it.

Been a few issues along the way, but recently the X axis servo decided it didn't want to work again!

Actually it was the 2nd time, but the 1st time (about 3 months ago) I was able to rescue it.  Sadly last week no such luck, so bit the bullet and swapped out that axis motor/drive for a new 400W Brushless AC Setup.   Quite an eye opener really, although very close spec to the Brushed DC that came out the Brushless motor out performs it in every way.

Anyway here's a vid of the machine running recently.

SmoothStepper USB / Re: Smooth stepper with C25 breakout board
« on: October 19, 2008, 11:02:16 AM »
For the Cubloc  See my thread at http://www.machsupport.com/forum/index.php/topic,1105.130.html

Some others here have used it too with great success.

It connects to the rs232 port on your PC and mach communicates via Modbus to control it.   On my Hardinge lathe it controls most of the machine.

The resistors are to reduce ringing on the Differential encoder input I think.   You may or may not need them.  I have not used them for the Heidenhain encoder I have connected to smoothstepper.

Analogue inputs will have to be interfaced another way, via PLC or similar I use and recommend the Cubloc PLC's.   Though the Pokeys now has A>D inputs.

I take it you are retrofitting a commercial machine??

1000 COUNT encoders on a G3x0 drive!   Probably there lies your problem.   the Gecko's error trip is fixed at +/- 128 encoder counts, so at 4000 counts per rev of your encoder the drive will trip at +/- 11.52 deg of following error which is not a lot.

It could be that you could tune the gains to work but then you hit either current limits (limits Accel) or voltage (max velocity) which would be power supply rated.

I have used the G3x0 drives successfully with 500 line encoders with small motors with sufficient reserve power in the supply, I could not make them work AT ALL on my Hardinge with 300w motors and 2500 line encoders.  I went to cncteknix tek10 drives for that, and even they were fiddly to tune and I had to use 1024 count error trip.
