Retrofitting a 1986 Maho MH400E

Hello! First question is about link gearbox library from github to LinuxCNC. How i can do it?
I was analize schematic of MH400T and don't understand how tool change works. I mean, it works like simple trigger with two states? I found time-relay in relay box, in schematic it corresponds to tool change. What is role of this relay? And, finally, i want to ask you: can you send me image of your LinuxCNC (HAL and ini)? More is better. Thank you!

PS: this forum works very bad on my PC, i'm trying to post this message 3rd attempt...

Best wishes, Denis.

Hi Dennis,
download the code:
github.com/jin-eld/mh400e-linuxcnc
look at the wiki:
github.com/jin-eld/mh400e-linuxcnc/wiki/...-Component---Testing

it says:
Copy the entire set of downloaded files from github into a folder such as /home/linuxcnc/gearbox_sim
cd .. up to you linuxCNC folder
sudo halcompile --install mh400e_gearbox.comp

But this code is only for the gear change, not for tool change.
You own one of the rare 400T models with a tool changer.
I would love to have one on my machine
Can you upload the schematic of the tool-changer ?
I can upload my latest configs (HAL, INI) tomorrow.

Hi Hanno! I'm talking about tool hold/release circuit, not automatic tool changer. My MH400T doesn't have automatic tool changer. Upload your HAL/ini please, it can be very usefull for me. Thank you!

Best wishes, Denis.

On my 400E, the tool is held by springs, and release hydraulically. There is only one Relay. You connect that relay to a HAL pin, and button of your choice. Push the button, hydraulic pump turns on and kicks out the tool. To put in a new tool you push the same button and when you release it, the gripper springs pull in the tool.
