I can assist you with setup hal and ini files, but at the moment I'm not yet able to share plc components or so. Because
they use special libs from my company....
On the other hand there is the "Mesa" Way, there is an much bigger community who can assist you...

Hello db,

I did complete configuration of 3 axis with Mesa cards. But recently there is big problems with Mesa supply and I tested Beckhoff Ethercat. It works and I plan to continue with EM7004 ( I will get one for test this days). Can you share your hal configuration for driving axis with EM7004?
Thank you.

Hello I have an old Weeke BP 10 wit a NUM 750 and i would like to operate this Machine with Linux cmc too. For that i have Mesa cards 5i25+7i77+7i71. I have seen that you have your machine also rebuilt. Can you give me any help with the wiring? Thanks

Retrofitting is almost finished, thank you all, for your sugestions. Does anybody know is there option to remove third zero in AXIS dro (to downgrade precision in mm) i think it could help us to make good PID tunning. We have problem, maschine moves jerky and vibrates when standstill. Weeke is woodworking maschining centre with 0.006375mm encoder count, and 0.00mm DRO could make things easier that could be good option for all woodworking maschines.

Thanks for joining tommylight,

after reading this instruction I followed every step, but i had no success. I ended up with same parameters I had.
Everything is ok, when machine stands still. But during auto-mode when i play some program, x-axis becomes very nervous. y and z both keep their calmness but X f-error graph goes 10 times louder.
I will post video with this problem and hal oscilloscope. Maybe someone can help.

Spindle is brand new, Hiteco powertec 4kW S1, ATC,with max 24 000 RPM. VFD is 7.5 kW KEB with ASCL (closed loop) tehnology.

I have a lot of other smaller issues, but this one is critical..
Thanks in advance, every help is appreciated .

Is there a chance that you might have a mechanical issue?
If the drive train for the X-axis is rack and pinion, I've seen worn components there cause all manor of issues that look on the surface like tuning problems. Look for things like worn or misaligned pinion gears, worn bearings on pinion shafts...
