arrr... I tried that .ini/.hal file combo and was presented with this error message (after changing "Machine configuration directory" to '/home/derek/linuxcnc/configs/TB6560') :
So, I tried copying those two files into my BookMachine directory and renaming them BookMachine.ini and BookMachine.hal . Running that, I get this error:

If you have a TB6560 you might want to start with the sample configuration for that board. It is a sticky called "Sample Configurations" in this section.
Of course you will still want to understand what drive timings and scale are and do.

In both cases the problem is a file being referenced in the INI file that does not exist.
Replied by andypugh on topic missing steps?
The reason for the problem is generally in the "debug file information"Could not open command file 'custom.hal'
...
Could not open command file 'rf-30_1.hal'
In both cases the problem is a file being referenced in the INI file that does not exist.

In the first error your missing your tool table.
When you rename your hal files you have to change the ini file entries to match.

I figured out how to get those files working, but I still have the same dropping issue.

O.K. are you saying that you are satisfied that the step timing / speed is correct for your drivers but the Z axis keeps going lower?
And from earlier post you are satisfied that there is no slipping or binding.
With the current settings do you have the same problem at slow speeds as high speed moves g0 , g1?
Have you tried dramatically reducing both the acceleration and velocity with the new timing settings?

I'll answer each in order
1. Yeah, I am pretty sure that the settings should/must be right and the Z-axis (as well as the other two) keeps dropping.
2. Yeah, I am absolutely positive there is no slipping or binding.
3. I do have the same problems at faster and slower speeds. I have tried reducing both.
I am sorry to be such a pain here... Thanks.

Have you changed that, and where did you change it? (and is your machine a simple three-motor system)
Replied by andypugh on topic missing steps?
Acceleration may be the problem, rather than velocity.3. I do have the same problems at faster and slower speeds. I have tried reducing both

Yeah it is a simple three-motor system based on a book by Patrick Hood-Daniel. I have tried asking for help on that forum as well, but I keep getting told that something MUST be slipping. I know that that is impossible. I have double- and triple-checked everything.
I changed both acceleration and velocity in Mach3 before I decided to try LinuxCNC to see if thath was the problem. In LinuxCNC, I changed those in the StepConf program.
One I have used was:
MAX_VELOCITY = 0.242941898527
MAX_ACCELERATION = 7.0
STEPGEN_MAXACCEL = 8.75
Another set I used was:
MAX_VELOCITY = 4.0
MAX_ACCELERATION = 30.0
STEPGEN_MAXACCEL = 50

So you have the same problem in both Mach and linuxcnc.
Do you have the problem when you move one axis at a time or only when you make a combined move?
Have you checked your power supply voltage / amps when moving?
At this point you might try removing the motors from the machine, mark the shafts and with the motors not driving any thing make several moves and see if the motors return to the proper position.

if your z axis is dropping , then the only problems it can be is that the stepper is either underpowered for the torq required
or you are running that particular axis at too high a step rate and that the stepper cannot cope with the additional weight
that it needs to lift .
or that your power supply is under rated and cannot deliver the amps needed
