how to make M7 (mist on) generate step pulses

Category: G&M Codes

Hello Andy,

Thanks again for your support.
Inputting "halcmd setp stepgen.4.velocity-cmd 40" from the terminal, while a session of LinuxCNC is cutting metal, works well and is so easy to do.
Now I can adjust (and optimise) the MQL flow rate on the fly, It also allows me to easily use different flow rates for both neat synthetic fluids and also water soluble coolant.

It would be cool to control the flow rate from a virtual slider pot on the AXIS virtual control panel, but I suspect that would be well above my 'pay scale'

Thanks again

Mike

What difference between DC mode and free-run mode in motor control?

Category: EtherCAT

I have an INVT EtherCAT servo that can operate in DC (Distributed Clock) mode or free-run mode. Could anyone explain the differences in performance between these two modes? Specifically, is DC mode more accurate than free-run mode in terms of reducing following error (ferror)?

youre right.
I just looked at gmoccapy_tool_sensor.ini
and it should be like
SUBROUTINE_PATH = macros
the instructions website did not mention anything for subroutine path
Now it works.
Thanks

The most important information is:
