How to configure Horizontal Boring mill

I think that you can probably run this as a trivial kinematics machine.
It would be very unusual for a HBM to make coordinated moves with the B axis, and even if it did the likelihood is that it would be done in standard rather than TCP G-code.

Have a look in the sample configs:
sim/axis/vismach/hbm
For a sample config including an animated 3D model.

Assuming that you are using LinuxCNC 2.8+ define only the axes XYZBW. (ie, 5 joints and 5 axes)

In the [DISPLAY]GEOMETRY section you probably want to use BXYZW so that the entire preview rotates with B rather than just the tool.

But, don't expect the G-code preview to be any more than a guide to the actual path, as the preview has no real idea where the actual centre of rotation is in the user coordinates.

You probably don't need MHz pulse rates. It's better to have the step lengths too long rather than too short (the space will follow from the step length and the frequency, but should generally be at least as long as the step)

We typically suggest 5000ns for step length as a starting point, the only reason to go shorter than that is if you can't reach the required motor speeds at that (it gives you a 100kHz step rate, which is 3000 motor rpm even if set up for 2000 steps/rev. )

So, start from motor max speed and steps/rev and work out what frequency you need to get there, and then only go below 5000ns step/space time if you really need to.

The setup times are even less critical, by definition you are moving at zero step/rev and zero speed when you change direction. So 20,000 is generally fine.

It makes no sense to run at the extreme limit of what the drives can accept, as that means that you are on the edge of it _not_ working.

There should be a parameter in the HAL file that you can set with "setp" command.

Something like
But it will obviously depend on which card you are using.

With the system running, open a terminal and find the correct pin with:

halcmd show pin *pwm_frequency
