Thanks for answering. When i run this code from examples its do. G21 G54 G18
F400

O100 SUB
G0 X10 Z0
O101 REPEAT [3]
G1 X[#<_x>-5] Z[#<_Z>+3]
G1 X[#<_x>-5]

O101 ENDREPEAT
O100 ENDSUB

O101 SUB
G72 Q100 X1 Z1 D0.5 I1 R0.3
G70 Q100 X1 Z1 D0.5 P3
O101 ENDSUB

O101 CALL

M2
When from this code i delete G72 line G70 working fine . But when i change G72 to G71 Linuxcnc freezing . Can someone direct me to right path. How to run G71 .
.

if you: 

1. Disconnect the encoder

2. Change the index input to TTL mode
(W1 left)

3. With LinuxCNC running and halshows "Watch" tab showing
    hm2_7i96s.0.encoder.00.input-index, does the state of
    hm2_7i96s.0.encoder.00.input-index change when you ground
    the IDX+ input (TB2 pin 13)?

My wiring is good. I followed the MESA7i96s documentation. I think everything is correct.
I've tested 5 RS-422 encoders with phase A+,A-,B+,B-,Z+,Z-. Or maybe my MESA board isn't working properly. I don't know how to get out of it

Good point I forgot to mention the specs
Current is 3A. Resistance is 1.3 Ohm
Holding torque 3 Nm
I run them with a 36v power supply.

O guess that about no voltage specification is a good point you don’t know what transistors are in there.

 

Lathe with Step/dir spindle.

Your picture above, you have to 99 listed as probe tool. But no tool loaded in software. Shows 0 as being the loaded tool.

usually you would have the files in your config folder but the main thing is that they can be found where the file paths in the ini file point to, so don't forget to add the [PYTHON] section and contents to your ini file and set the appropriate paths.
See the sim configs for how to set things up.

sweet

and for the host interface USB?
this will not really work
LinuxCNC is a little bit different to other controller like GRBL,
you need a realtime loop between board and host and this will only work with Ethernet/Ethercat/SPI(raspberry) or LPT., not with USB or UART.

If you need almost ready to use Gateware/Drivers for your board, you can look at:

github.com/multigcs/riocore/
(github.com/multigcs/riocore/blob/dev/doc/BOARDS.md)

this is a gateware generator and all the FPGA stuff is written in verilog,
but it use W5500 UDP interface or SPI.
There is also an UART/USB plugin, but only for testing, not for realtime use.

you can take a look on my youtube channel, there are many videos with different FPGA's running RIO:
www.youtube.com/@unixconf/

but i can understand if you prefer to write your own software, it's also fun

Sorry
Power 5 W

Thank you for the help. I am going to use EP4CE10E22, Verilog, and it will be open source project.
Board parameters:
Dimensions 67x76x20 mm
Weight 60g
Supply voltage 12-24V
Power 0.5 W
Opt. isolated inputs 24
Outputs: digital 16 (0.5A max)
analog 2 (0-10V)
JTAG, USB

okay thanks ...

If I want to fanuc style tool offsets .. I will do remapchange tool tablethen allow the wear offsets
all other files have to be in the same folder too?

I want to move from 2.8.4 to 2.9.4 and I am searching for updates which should improve my life

thanks

When LinuxCNC sends a command to the frequency controller via Modbus RS485, the G-code "freezes" or stops executing commands

And unless you disable SPI you can not use the SPI pins for GPIO in linuxcnc
 

This is the problem that I could not see.
Thanks for everything.
In my configuration I have used GPIO7 and GPIO8 as I/O .
After disabling the spi, I solved the problem....

I find it very assuring. No seller seems to think quoting any opertating voltage would be a clever idea.

If those basics are not covered I tend to stay away from offers.

p.s. The NEMA23 only refers to the frame size (mount hole pattern) the electrical specification is totally independent from that.
Voltages, current and how fast you need to run your motor are more important.
