Re: Centroid Operator Control Panel Interface Board: USB-BOB

If it is only drawing 1mA when you put 12VDC across the LED terminals, then it is very likely that it already has a resistor built in.

Re: Kitamura Mycenter Zero - DELTA Ethercat Retrofit

Delta C2000+ + CMC-EC01 (EtherCAT) + EMC-PG01H SIN-COS Encoder Card for the Fanuc Servo Motor: This setup adapts modern Ethercat communication to interface with the existing Fanuc servo motor. You may want to review that one with someone knowledgeable at Centroid. My understanding is that spindle d...

Re: With the Atc option, Can we run without the ATC

If there are a whole number of encoder counts in a full revolution of the carousel, then it should not matter if the number of encoder counts per tool position varies. If you use logic similar to what I posted above, then you are always reading absolute (cumulative from power-on) encoder counts, and...

Re: why is my origin inverted?

On a typical knee mill or bed mill:
X+ moves the table to the left.
X- moves the table to the right.
Y+ moves the saddle toward the operator.
Y- moves the saddle toward the column.

Re: V5.1 Lathe distance to go isn't working

Phil,

Did you have this issue on the runtime graphics (RTG) display; or on the G-code display; or both?

Re: With the Atc option, Can we run without the ATC

What causes your carousel to rotate? Does it rotate in both directions? What locks it in position when it arrives at the target? Here is one example of reading an encoder (from the Oak encoder input #5) and translating it into the nearest carousel position: ; Monitor the carousel position ; There ar...

Re: VFD control voltage

This could also be an analog oscillation problem. That theory would be supported if you get predictable spindle speed using a battery (e.g. 9V gives you 90% speed, 1.5V gives you 15% speed). If that appears to be the case, you could try one of the "snubber" solutions. See https://centroidc...

Re: dxf import

By "a real point", I assume you mean known numeric coordinates (presumably in the drawing, relative to the drawing's zero point). I do not know of any way you can just enter such an offset. The best approach, if you cannot get the CAD coordinates to be where you need them, is probably to j...

Re: Hardinge CHNC4 Retrofit

Did you look at the Z motor power wiring, to see if you can find out where the 63 Ohm measurement came from?
