I have ( G01 X 1.0 F.006 ), yet the actual feed is about 30 ipm. ( F.030) By default, feedrates on the lathe are in units per revolution (e.g. inches per revolution, assuming you are set up for Imperial units). The actual feed will be slaved to the rotation of the spindle encoder. For example, if y...

What did you end up at with Kp, Ki and Kd?

You might try cutting back on Ki (maybe in half or less).

Do you also have a rotary encoder on the motor that you could use, or do you only have the linear scale?

You can update to CNC10 v2.38.

If you have at least 512MB memory in your computer, then you can update to CNC10 v2.70.

Well, usually that means your spindle drive is reporting a fault. More specifically, it would mean that INP25 on your PLC is open. If you have an inverter (aka VFD) for your spindle drive, you should connect the normally-closed contacts of its fault relay between INP25 and Input Common. If you just ...

Yes, you need to set "Motor Revs/Inch" to the number of revolutions your motors must make for each inch of travel. That incorporates both the pulley ratio (which you have to know or measure) and the lead of your ballscrew (which you also have to know or measure). You also need to correctly...

If you know where we can buy good quality 29 in-lb NEMA 42 servo motors for $350, please share.

When you try to jog X-, does it say "407 X- limit (#2) tripped", or does it say "411 X axis (#1) full power w/o motion"? If it says "limit tripped", then your switch circuit is open. Use the PLC diagnostic display (alt-i at the main screen) to see whether the first six ...

Most CPU10 PLC programs use Parameter 177 as a "fault override". So yes, setting every parameter from 171 through 178 to 1.0 will make the "lubricant low" message go away. It will make lots of other error messages go away too. Some of those error messages may be things you would ...

It depends on the direction reversal setting for each axis. Because you have direction reversed on X, your logical X- limit needs to be the internal/electronic X+ limit (that is, INP2). You should enter "2" for the X- limit number, wire the switch to INP2, and close the defeater switch for...
