Retrofitting a MAHO MH500W '89-'90 with hand-feed

Category: CNC Machines

Hi Petmakris!

I'm starting a linuxCNC conversion on a MH500W2 with a faulty Philips 432/9. Planning to use all your hard work in order to get it up and running again. I'll be using a Rpi5 and a 7I97T and three EXEs.

My first step has been to wire the mill to the 7I97T, but i have a question about the "Limit"s. In the MAHO documentation the limit switches seems to be connected in series 204-207,
 
 

did you rewire these or simply used 205,206,207 as limit X,Y,Z?

 

Regards,
Hampus

How to use "Opt Block" and "Opt Stop" in QtDragon

Category: Qtvcp

Oh! OMG.

Now I know what those buttons do. I thought they were supposed to be activated by the slashes, and now I've just learned about those M0, M1 codes.

[Dang, I have so much to learn :-( ]

Thank you!

Linuxcnc error

Category: General LinuxCNC Questions

Hello!
I hope you don't mind, if i ask here a question about an error in LCNC.
In the config, at start up no program is loading. (OPEN_FILE = "")
I have a lathe with 3 axis. X axis has an electromagnetic brake. When disabling the drivers pops up an error "File not open" in the right bottom corner.
On the lathe there is a microswitch, to check, was the part cut off. If it pressed, pops up a message component that the cutter tool is boked.
Today, when i pressed manually the switch, the default message pops up and also the "File not open" in the right bottom corner.
The "File not open" error in the right bottom corner also pops up if i press the Run Program button. It is logical.
Not really understand, why is it happening.
Can anyone give any advice?

Update:
We just assembling the mechanics and the "File not open" error pops up again without pressing/switching anything. The spindle servo was turn on a few times. But there are EMI filters...
It looks like something pressing the "play" button (Run Program)

Update2:
The path to "on_abort.ngc" was the error

Yes this needs to be done to work correct.
But for some reason if you change baudrate to max speed this modbus module initially works after 1st reboot in high speeds but not work after 2nd
reboot.
Stop responding and to return in working condition needs hard reset to go in default baudrate.
What can be this problem ?
