Retrofitting a 1986 Maho MH400E

Glemigobles wrote: My Maho is an E model just like yours. The HF spindle is the ER collet type. I was curious about the possibility of setting it up in LinuxCNC because switching it on and off manually is a drag, and setting the frequency using the knob on the VFD sometimes gives poor results.

You can use three different configurations one configuration with the vertical maho head, one for the horizontal spindle (with the axis y and z swapped so the z is always in line with the spindle) and one configuration for the hi speed head.
Depending what head you are going to use, you have to start the right configuration.
You can also add a b axis in the first configuration (the rotating head), and add a stop wen b axis make a move, rotate the head manually and continue with the program.

Nice that it worked, but I am slightly confused why you thread-milled it when you already had it set up on the lathe?

Unfortunately, when I got the Boley, it only had the fine feed mechanism and the associated two change wheels. The rest of the change wheels, the pinion for the spindle and the banjos were lost.

I did bodge up a spindle encoder and stepper mount to drive the leadscrew...

... but only hooked up a temporary drive and PC to use it to make the first back plates. I have been torn between CNCing it properly, like you did your Holbrook with two jog wheels on the apron to still do manual turning, or getting a set of change wheels and making the banjos. I rather enjoy manual turning on a lathe.

Now that you have you Holbrook finished for a couple of years, do you find you use the jog wheels like a manual lathe for those quick 5 minute jobs where specific dimensions aren't critical?

No, pretty much never as it is easier to use my turn / face / thread macros.

I do use the X mpg for parting, but I will probably make a macro for that at some point.

I used two different configs for my maho. One horizontal and one vertical. Working great. Only annoying thing is switching between them in the same setup.

Hi,

nice thread milling video Mark !
At the moment I'm working on this project which will be documented in Peter's CNC-Ecke :
