LinuxCNC + Mesa 7i92TF + Gecko G540. Docs are useless. Help, Please!

Category: PnCConf Wizard

Thank you so much for pointing me in the right direction. 

Yes, any AI I asked eventually started hallucinating code that broke things. 

I did have someone send me a template HAL & INI set for the machine I am using (a Platform CNC with upgraded linear rails. Excellent hardware, currently being let down by confusing software, and its operator.) I was able to cobble something together that mostly worked, after much iteration. Since this was done manually, it didn't help me with learning and using PnCConf, which I would prefer. 

At this point I have everything moving, but until I sort out homing, the Y & Y2 axes are not moving in unison. They are seen as separate Joints 1 & 2. I assumed there would be some way to simply lock them together as one gantry joint(?), but apparently that's not how LinuxCNC works.

Yes, I have flashed the G540 firmware to the 7i92 card.

I would start looking at
- encoders. With the current stm32f407 the quadrature counters are tied to certain pins, and max 4 such hardware counters. Code is in E3000, would copy that.
- EtherCAT chip, would base it on LAN9252 (which most of the cards use) due to Ax58100 limit of 2x16 pdos. Don't know of a limit for LAN9252, it's not less than 2x16. 
- Opto-couplers, would revisit.

If you are thinking of stepper generator with encoder inputs, say for four of them, would base it on E3000 for the user code and extend to four encoders, code is already there. soes library from E7000. Hardware will be based on E3000 around stm32, around E7000 for EtherCAT.

One can think of one card supporting 1 drive. Or 2 stepper drives. And use multiple cards

In linuxcnc 2.10 there is 64-bit integers, so no risk for encoders overflowing. 32-bit isn't quite enough at least for spindles.

Is it just an idea, or are you going to do it?

Hey thats pretty awesome. Love the monarch also!

Is that using HAl-Core?

Do you have a github? Im looking to do something similar to this but with a custom GUI.

Hello Hakan and thank you for all your work.
If I want to create a small PCB in order to add encoders, compatible with LinuxCNC, which version of your project would you advise in order to modify it?

Thanks

I am using hal only with a mesa card to control a monarch lathe spindle. (so encoder, 2 analog drives and some i/o)



Works great.

Module ec_master not found in directory /lib/modules/6.1.0-25-rt-amd64

Category: Installing LinuxCNC

I solved this on my Zorin machine by:
1. copying the ec_master.ko module from /lib/modules/(uname -r)/ethercat/master/ into /lib/modules/(uname -r)/kernel/drivers/ethercat
2. returning to the install folder
3. running make clean followed by sudo depmod -a
Hope this helps.

Im looking into this as well, is there a clear cut way of running/interfacing HAL with a custom software?

I guess the real question is how to separate HAL from linuxcnc.

Thanks a lot, i already find this kind of topic but never found the right one. i will read and try it.

I have tried to change the configuration on the hal file using mux4 etc like this, but my stepper motor still doesn't move, maybe because it doesn't have the  stepgen.02.position-cmd parts. But i think it will be much easier with extra joint configuration.

Have a look at 'extra joints'. sim configs can be found in 'configs/sim/axis/extrajoints.
github.com/LinuxCNC/linuxcnc/tree/master...sim/axis/extrajoints

There is also some information here:

I see these two lines
[35409.201765] EtherCAT WARNING 0: 12 datagrams TIMED OUT!
[35409.331702] EtherCAT WARNING 0-1: Other mailbox protocol response for eoe0s1.
The first one with datagrams TIMED OUT is usually due to network adapter perfomance.
If you have a Realtek network adapter, install the realtek dkms linux drivers.
12 datagrams timed out isn't too bad and it should still work.

The second line indicates your drive supports EoE, Ethernet over EtherCat.
Unfortunately, linuxcnc-ethercat doesn't support that and people have all kinds
of problem to get such servos going.
The most straight-forward way is to download the IgH Ethertcat master and build it
with the flag --disable-eoe.
There is another way - read out the eeprom content of the drive, modify two bits,
and write back. forum.linuxcnc.org/ethercat/55806-long-i...660n?start=20#337450

Move stepper motor only with push button

Category: HAL

I’m working on a CNC lathe project using mesa card 7i98 where I want to add an extra stepper motor to control the chuck lock/unlock mechanism. The goal is to operate this lock only using a push button, completely independent from any G-code commands. This is to prevent accidents in case there's an error in a G-code file that could unintentionally move the chuck lock.I’ve already managed to configure the stepper so it can be moved using a push button, but the issue is that in my current configuration the motor is still connected to joint.2 and axis.a. I’m worried that if something goes wrong in the G-code, the machine could send motion commands to this stepper as if it were a normal axis, which might release the chuck during machining.What I want is a clean way to configure this stepper as a completely independent device, not tied to any axis or joint used by the motion planner, so it will only respond to the push button input.Has anyone implemented something similar or knows the proper way to configure this in LinuxCNC?
