Centroid Community CNC Support Forum

I've done two Acorn retrofits and now I have an old Morbidelli Author point-to-point. Are there any Centroid products that would work with this machine? It has Yaskawa "Servopack CACR-SR" drives. The old NUM controller has optical connections with the relay boards.

The machine runs okay but the ...

with 13" Z how do you get the DRO to +98.8845" ?

Uwe


I don't know, very mysterious indeed. Probably related to the absurd feed rate mentioned below.


I suspect that your problems are caused by the 50" per revolution roughing feedrate. You will also run into problems with the 10" per rev ...

I tried to run another Intercon program. This time the tool moved into position but stopped at Z0.000 and it gave me a 327 Fault: Job canceled.

I reset the control (big red reset button) and the Z DRO went to 100.xxx (no carriage movement), my lathe has a Z travel of 13" as configured. And like a ...

Here's the Intercon file

I am playing with intercon, and tried to turn a simple punch from a piece of brass pipe.

The program will run the carriage back to home, then as the tool moves in for the first cut, the spindle runs up from the programmed 500 RPM up to 800 or so, then I get a "438 Spindle slave position error ...

Got it..thanks! I'm new to the lathe world.

The max Z travel changes with the location of the tailstock. This means that sometimes the software travel limits could be more than the actual Z travel available. Is there a way to address this, or do we just depend on the limit switch to stop the axis?

I'm testing the machine with air cuts on some of the sample programs included with CNC12 Lathe. Both PAWN.cnc and Sample_Part_1.cnc start with the Z axis on a rapid straight toward the chuck. I stopped it before it crashed. I think I've setup the tool offsets and G54 correctly per the Youtube videos ...

Another vote for the wireless MPG, it's a game changer for manually setting WCS.Yes it feels like a lot of money, but the MPG is a bargain for what it is.

Some folks have adapted video game controllers as pendants, heck some people use them to control deep sea submersibles...

Thanks all for the help! Worked perfectly the first try. Verified RPM with tachometer and it is dead on at 4000 counts.

Input DB9 Pin vs. wire color from original encoder:

2 = Black
3 = White
4 = White/Black
5 = Red/Black
6 = Blue
7 = Orange
8 = Green
9 = Red

Good tip Uwe, although I still need to ID the wires. I suspect the green cover is just for dust, and there is a nameplate on the actual encoder underneath. But to access it I'll have to disassemble the entire cabinet. Was hoping to avoid that mess!
