Centroid Operator Control Panel Interface Board: USB-BOB

[friolator]

On my lathe I really only need to use two of the rotary encoder knobs: one for spindle speed and one for feed rate. I don't think I need to control rapid speeds since it's a very small lathe. Can the third rotary encoder be used as a multiplier for the X and Z MPGs I'm going to add? eg: 1x, 10x, 100x, applying only to those MPGs? If not, is there another way to achieve that functionality?

Laying out my front panel now and I want to account for all the buttons and knobs I'm going to add.

In theory, yes. It will require some PLC customization though.

1x, 10x, 100x is a planned functionality for the button inputs. You could use a three position rotary switch and three button inputs on USBBOB and assign that all in the Wizard (if Acorn/AcornSix system).

Cool. the 3 position switch works for me. I'm pretty sure I'm not going to come close to using up all the inputs on the USB-BOB, so that should work for me.

and fyi...x1,x10,x100 the buttons on the vcp can/will work in conjunction as well

Super excited about this addition. What are you projecting the cost will be?

[cnckeith]

try to keep the kit under $250, its tough these days!

Is that a 9mm mounting hole for the rotary encoders? or something different? Most of the ones I've used and have kicking around here with a 6mm shaft have a 9mm mounting diameter. Just checking before I start drilling!

Yes, you should do a clearance fit for M9x0.75 threads + 3mm diameter hole (or D shape) for the anti-rotation lug. The anti-rotation lug is 9mm away from the center of the shaft.

What type of inputs do you want to be preprogrammed by Centroid and included with the Wizard?

One that might be useful (though may not need to be in the wizard, I'm not sure) - is an override enable/disable. I want to have to hit a switch to enable the feed and spindle speed override knobs, so that if they get accidentally bumped, they don't do anything unless I've got the overrides enabled.

Similarly, MPG enable/disable would be useful as well, so you don't make a move by accident if you bump the wheel.

Is that possible?

Perfect. Thanks!
