The wiring will work for 3-4Axis mill and for Lathe.
For Lathe you need to set 'LinuxCNC->Machinetype' to lathe
and maybe remove 2 stepdir plugins.

If you need a Spindle-Encoder, you can add it freely to the other free ports.

It worked here. Running 40 times.

Pullups and pulldowns are possible on both but only after configuration

Xilinx chips have the added option of pullups before being configured
 

Hello, 
i would like to run delta vfd-b over rs485 modbus and integrate with qtdragon hd GUI, can somebody please point me in the right direction i am completely new to linuxcnc, 

thanks 

Glad you got a handle on it!

I have an external momentary button and i want to toggle between halui.flood.on and halui.flood.off
How can do this config ?

Also i have an output pin that activates lubrication pump and an output pin that activates a solenoid hydraulic valve that releases spindle tool clamp
where in hal must connect it in iocontrol v2 ?

7i80hdt that is not xilinx fpga has the pullup only limitation
or can configured both pullup and pulldown with weak internal resistors ?

Thank you! Yes, everything worked out! Your instructions were easier. I'm trying to design)))

In the ini file, this:
[TRAJ]
COORDINATES = XYZ
Should be
[TRAJ]
COORDINATES = XXYZ

My old system that my machine works on is axis 2.8.0 running on linux mint 19.3 xfce with linux 4.19.106-rt46-lcnc.
My new system LMDE 6 Faye,up X1,joint 0, X2 Joint 1, Y Joint 2, Z joint 3. I will try to attach my ini, file and my Hal. If anyone could help me, I sure would appreciate it. Thank you. Travis

Funny thing is, the Mesa 7c81 and a stacked RPi look like a more compact solution.

NVME would be nice, the RPi5 with a NVME drive is blazingly fast.


Did you stick with the Mesa fpga pin to 7c81 layout ? Or did you change it to make routing easier ?

If you change things around, especially the clock signal, the SPI_CLK for comms is a little tricky to work out to begin with.

Sorry don't mean to add feature creep, man I wish I could design a simple board for the KSZ8851 Ethernet chip for my mesa clone thingy. So hats off to you Old Chap.
