No. The DC1 becomes drive #1. Typically you would use it to move a rotary table that is axis #4. When you set P300 - P303 = 2, 3, 4, 1 then you are telling CNC12 that you want: Axis #1 (X) to use drive #2 (the first drive output on the Allin1DC) Axis #2 (Y) to use drive #3 (the second drive output o...

The warning is correct. The "Rapid to" depth (the R value in the G code drilling cycle) needs to be at or below the initial clearance height. You have it above the clearance height, which is incorrect. The "Help" graphic is incorrect. It has the labels reversed. In Intercon's voc...

All Centroid CNC controller boards now require a Power Cycle after a Hardware Firmware change has been made (for instance when installing a new version of CNC12 or switching from Mill to Lathe CNC12). Are there now board firmware (presumably mpu*.hex) differences between mill software and lathe sof...

The encoder probably is on the servo motor. But you can figure out what the worm ratio is once you know the number of encoder counts per motor rev (by looking counts between successive appearances of the index pulse), and the number of encoder counts in a full revolution of the rotary table.

Then why does it change mine and many others to proper spindle output in cnc12 mill with a ratio of -.117 entered into parm 65 or aka wizard entry spindle low gear ratio and has for 3 years with my encoder mounted on top of the spindle. :?:... And i have a comercial grade hand held laser tachometer...

Once you have encoder input working, you can watch the count ("Abs Pos") and the index pulse indicator on the PID Configuration screen. You can disconnect the motor power leads from the DC1, and hold them to a 12V batter or battery charger, or any other low-voltage source that is powerful ...

Since it is not a limit switch, you would not wire it to either of the limit inputs on the DC1. Instead, you would wire it to an available PLC input on the Allin1DC. Then you could enter that input number on the Machine Configuration -> Motor Parameters table, as the minus home, plus home, or both, ...

Parameter 820 or Parameter 412?

Did you assign BackGear to an input, using the Acorn Wizard?

First, you would not edit the mpu.plc file. You would edit the .src file, then compile it to make a new mpu.plc file. Yes, there is a copy of the source file in comments at the top of mpu.plc, but it is just there for reference in case the original source file has gone missing. See lines beginning i...

Putting the spindle encoder on the top of the spindle of a knee mill is equivalent to putting the encoder on the motor. The top of the spindle does not rotate with the tool when you are in back gear; it rotates the opposite direction, and faster. Maybe it was reporting the right RPM when you were ru...
