interesting. Im playing with the servos now. Today im getting an error code ErC1.1 Synchronization loss on all 5 drives. and ErC2.0 SYNC signal loss on some drives sometimes. I will power cycle PC and see what happens. my 3 axis config seems ok.

Hi,

Please help with how to wire a 24VDC contactor to the Mesa 7I96S to switch on a wood router from LinuxCNC.

I would like to switch a wood router from LinuxCNC. I have the below 24VDC contactor and flyback diode:

- Contactor: www.tropac.com.au/10-Pole-24VDC-Coil-5.5...Contactor-LS-Metasol

- Flyback diode: www.jaycar.com.au/diode-fr307-1000v-3a-d027-pack-10/p/ZR1052 

I've learned how contactor works. I have wired and able to switch on a Dremel grinder via this contactor.

I think this is how I should wire it:


Is it correct, please? 

Thank you and best regards,

...behai.

Hectic weekend...

Hello. I have a lathe with a spindle on a servo motor and step/dir control and feedback via the encoder of the same drive on 7i96s. Everything works well. I also have an unfinished project on 7i97, where the spindle still works in an analog way. Step/dir is also planned. I can send the working files of the lathe.

You cannot use the standard release as they are only updated about once a year.
For a binary update, you need to use the image built by the LinuxCNC buildbot:

buildbot.linuxcnc.org/

(The page is a bit old as 2.10 is the current LinuxCNC master version and 2.9
is the current release version)

 The other option is to build from source:

www.linuxcnc.org/docs/devel/html/code/building-linuxcnc.html



 

Comp-Style:
github.com/jzolee/HAL2UDP/blob/2.0/LinuxCNC%20driver/udp.comp

pure C/C++
github.com/scottalford75/Remora-NVEM/blo...emora-nv/remora-nv.c

what FPGA you want to use ? Verilog, VHDL, nmigem ,... ?
Open Source or closed ?

Ther is no 2.10, where can i find it and i download the 2.9 now, and same problem help please

Hi.
I am new in Linuxcnc. I am going to design my own board use FPGA. I do not know how to make driver. I have experience in c c++. May be somebody knows how to do it, or where i can take any sample driver or any information.

The drives common or GND signal should be connected to the 7I77 power GND with a separate wire. Where is the power GND on the 7i77? 

This would be the drives analog common, or if the drive has differential inputs, Analog in -

Since I don't use windows and therefore also a TwinCat,
I have been looking for a way to convert my ESI files under Linus and write them to the EEPROM.

I have to say that there is already such a tool in C,
but you can only use it for their hardware.
So I thought I'd write one in Python under the GPL.

it's still in the early stages, but the test data I have is written 1:1 bit-accurately in the same way as the siitool does.

github.com/multigcs/esitool/

 

In cases where you have an unsigned spindle speed device (like an analog 0..10V VFD)
and encoder feedback, It might be better to use the signed commanded spindle speed
into the PID and just use the ABS on the output of the PID component to always get positive
analog values and also use the ABS components is_positive and is_negative pins for driving
the VFDs FWD/REV controls.

 

ready for testing:
github.com/multigcs/esitool/

there are some testfiles in tests/
and they are all bit exactly as generated by the siitool

but i need more testfiles and maybe some tester

That points to hardware issues, are you sure:

The index wiring is correct.

The encoders actually have an index output.
 

i do that, but never nothing

Note that 'genserkins' uses 'modified' DH parameters.
Have a look here (there is also an example of how to derive the parameters for a manipulator):
