I'm wondering if I should have said anything. :)

The short answer is 'yes,' you can append lines to the end of the PLC without having the source file.

Here's the problem(s): You need to either...

To swhowardno1: The issue you describe with the Z axis not moving and no errors or faults could be the Z axis not coming into position at the end of a rapid move. If that is the case, it is likely...

That doesn't appear to be a Bendix/Autocon/DynaPath System 10. I used to work for that company and the circuit boards would have had a logo and a seven-digit part number. What I do see is a reference...

The text event:

Example:
N0010 (T) This is a comment

is used to place comments or instructions into the part program. A text event is not used to make any machine movement. It sounds like you...

The CNC Executive disk you're looking for is going to have to come from Dynapath directly. The executive software is keyed to the serial number of the control and I've never heard of anyone getting...

Refer to the DynaPath website:

DynaPath

It sounds like the control thinks it's got a spindle capable of orienting (which, admittedly, is part of an automatic tool change.) You probably get the same error message if you execute an M19...

Whoever applied the control to the mill should have set the M06 to do a manual tool change. Sometimes that's as simple as stopping the spindle (the M06 includes an M05 code), then moving to the Home...

I'm more familiar with the Servo Dynamic drives, but I'll take a swag:

YC - don't know
SG - Signal Gain (Command Voltage Input Scaling)
BL - Balance
RC - Compensation
PC - don't know
TG -...

The '$' is the conversational end-of-block character.

G-code blocks would use the line feed character as end-of-block, usually denoted as <LF>. It is an ASCII code 10.

The 'D' code in blocks 500, 502 and 504 are direction codes (0=CW, 1=CCW) in the conversational format and are needed. Also, I just noticed that your 'E' code (fixture offset) in block 6 is too...

I didn't check every detail, but the code certainly looks like DynaPath conversational. It should load and run. Whether it gives you the exact part you're looking for, I can't be sure.

If this is a DynaPath branded lathe (you didn't say), then txcncman is probably on the right track.

Yes, the gear shift is manual, but there is no switch to tell the control which gear the spindle...

A machine tool builder like Compumachine had the ability to alter the way an axis references. Sometimes they would set up the machine to hit the physical limit switch, then reverse the axis and...

The event (same as block) that looks like:

N10(T)FIXTURE OFFSET$

is the correct format.

The (T) indicates a conversational text event and there is no equivalent in the DynaPath G Code...

Please tell us the manufacturer and model number of the spindle drive. I am not that familiar with adjusting drives, particularly for spindles, but if you post this information, perhaps someone else...

Probably not a programming issue, it's more likely the spindle drive not running the same speed in CW and CCW.

Verify this by programming the spindle CW, using an M3 code, at a your tapping...

No DynaPath mill control ever had a parts counter. The lathe control does, but not the mill. I'm also not aware that the Tree or ZPS machining centers had one set up by the machine tool builder.

That should indeedl cancel any tool offsets that you have active and give you the desired result.

The "box with the keyboard on it" is usually just the pendant station that will have the CRT display and keyboard, as well as a couple circuit boards to interface pushbuttons and lamps. You want to...

The tool offset in this case will activate both a tool length compensation and a tool diameter compensation - the numbers following the T number in the T table.

On a Delta 40/50/60 control:

1. COM1 is a 9-pin RS-232 serial port for sending, receiving and drip-feeding part programs. There are no parameters to enable/disable this port. You can bypass the...

Because you are using the Random Tool table, try calling the tool (with a T code) first, then in a subsequent block, program the M06 by itself.

The idea is to get the tool changer to position the...

The transmission from the DynaPath is ASCII text, readable in Notepad. It sounds like DNC4U is trying to "translate" something that doesn't need translating.

I suggest that you go through the...

The attached txt file can be loaded into the catalog. The attached pdf explains how to use program.

This part program isn't fancy, but it accomplishes what you are looking to do. The downside is...

You can enter an M-Function event (an event type 9) in a block prior to the Circle Mill event. For example, enter the Circle Mill event at N0010, then you can put the M-Function event at N0005.

I would have to say the manual is the best source of information on the Circle Mill event.

A couple not-so-obvious facts:

Since the center of the circle mill is described in the event, it is...

The control should be toggling the CTS (Clear To Send) signal on pin 5 of the 25 pin connector on the CNC side. In other words, when you press the key to load a program and the display says 'Busy...

Be aware that the PIC Revision message is a bit of a red herring. Message contents are stored in the parameter prom, not the PIC prom. You can change the PIC prom all day and the fault message...

It's possible you've now discovered why the EEPROM was marked "BAD."

There are a couple things you can try, though. First, does the spindle switch work in the CW position? Next, try executing an...
