A floating G code window would be great

ftomazz there will be someone on cnczone who has those parameters for the 21 control. Best to put a help request out on the Fanuc section on cnczone.

If your machine has lost position it will be as you say because the battery backed encoders you have need the batteries replacing.
The idea is that when you power down the machine the encoders use the battery to store  their position so no need to home the machine on start up.
To re set them once the batteries have been replaced, simply move each axis to a reference position of your choice and zero the machine. You could use an edge finder in the spindle to touch off on a fixture on the bed if that's easier for you.

You will have a really nice control once it's back on it's feet

Bob,

I've sent you a PM.

Well with regards to the parameters I can get a set for you or you can go on www.cnczone.com and get a set for Fanuc OTB.
 
You have to load the first few by hand to get the rs232 working and a few other things too.
The servo alarm is because you have no parameters as yet.

I have a friend who can help you out on set up etc I'll get in touch with him for you.

In reply to Melee, no need to go to steppers and redo all the i/o on the machine to get it working with Mach!
You can drip feed programmes of any length  to the control  so no need for a big memory storage.
Why go to steppers and run open loop when you have a perfectly good digital closed loop set up that will be way more accurate!
Just turn the rapids down to 25% if your worried about crashing

On the tool nose radius issue, it's far easier to change it on the control. Re loading your G code file every time you want to accommodate tool tip wear can be a  real pain!!

They know their stuff when it comes to making a good  cnc control  over at Fanuc

Those servos and drives you have are very high quality and very expensive to buy new!! Keep them at all costs if you can...also the Fanuc OT is a great control..why replace it..??

It will wipe the floor with Mach at the moment as it should have CSS and tool nose radius compensation as standard..

If you are short of memory space there are various sellers on US Ebay selling memory upgrades..or try www.memex.ca

Feature Requests / Solid simulation - Integrate Mach3 with Vericut or Camplete True Path..?

« on: September 14, 2009, 04:06:48 AM »

Wouldn't it be great if a program like vericut or camplete Truepath could be integrated into Mach to give solid simulation when running a program. Would save having to design a solid sim program from the ground up..

http://www.camplete.com/truepath/collision.html

These programmes are for verifying G code but also allow for complete ground up machine design so you could create an identical model of your own machine in the sim and it would run the sim as the G code was executed in real time!!

The Mazak Matrix control has this and it looks awsome!! They even put the pallet and tool changer in the sim!

Ions I think you could still control that spindle drive with a Galil motion card in analogue mode..Has it got an encoder on the spindle motor..? You did say it was 0-10v analogue when you checked in the manual..is that correct.?

If you would like to send me a copy of the manual I can check it out for you..
