Retrofitting a 1986 Maho MH400E

I don't think you need the or2, the GUI turns the spindle on outside of HAL.
You can just connect the button direct to halui.spindle.start to add a manual spindle start button.

Thanks Andy, I didn't look at that yet, but probably will need OR2, as I have already netted the HALUI pins to the gearbox COMP, so it can turn the spindle on and off.

Yesterday, I made a new, much more conservative program to mill down the sandvik lathetool holder, using a brand new 10mm chinese HSS four flute. Use 2mm depth of cut, 50% engagement, 480rpm and 75mm/min feed. The first ~250mm went fine with nice chips, but then it died.





Although I did use cutting oil, itprobably need flood coolant to keep HSS cool enough to work in that steel. Oh well, another end mill for the hall of shame. Lucky I bought the Clarkson T&C grinder last year.

Hi, I think that you should connect hal and not halui pins to gearbox COMP for machine control. I thing halui pins intended use is for the user interface, hardware and software.

Controlling the spindle from an independent bouton and from the rest of the software with or statement needs more thought.

Mark, can you check in your machine if this is ground?
John

Can you take a close photo to transformers connections?

Hi John, thanks for your input, you are right about that. The relevant spindle control nets which I currently have are these:
And here are the functions which I have had to comment out due to conflicts.
I used the halui.spindle.stop to give the gearbox control of stopping the spindle. Since there is no motion.spindle-stop pin, should I have the gearbox net to the motion.spindle-on pin and setp false to stop it? Or just have the gearbox comp setp motion.spindle-on false, from within it's code without going through a net?

Hi John,

Lucky my new bellows have not yet arrived, so I still have the guards off and can easily remove the cover and photograph the transformers. Will probably have to wait for the weekend though.
Mark

I think the ''setp motion.spindle-on false'' approach is beter.

Can a comp even set a parameter directly? I thought the way the HAL works is that the comp connects to the rest of the hal through pins, so a comp can not change a setting it is not connected to though a pin.

When the gearbox comp wants to stop the spindle, it sets

to 1

I netted that to , but if I changed that net to and invert it , it should do the same thing, but free up my halui.spindle.stop pin for my external button shouldn't it?
