rs485 huanyang speed control

Eureka!!! I found the problem!!!

Donning safety google, because I am now sitting pretty close to the spindle, I energized the system, and launched LinuxCNC...

While probing the spindle-command-rpm-abs signal, I clicked on the RPM increase until I got over 6600. As soon as I passed it, the motor RPM went up, and the at-speed indicator finally went green. : )

The system was sending correctly scaled RPM commands, but the sent speed was lower than the user-set VFD minimum, so that is what it was giving me. (Apparently, Huanyang air-cooled spindles motors don't like running under 110Hz, the water-cooled ones below 100hz, so I had indeed set those values.)

Editing the custompanel.xml control, changing the 3000 to 24000, fixed the visual widget issue.

The too-many-clicks issue was lessened by editing the .ini [DISPLAY] section, adding:
Ref: forum.linuxcnc.org/21-axis/34056-spindle...nimum-starting-value

Though, the build code would have to be changed in Axis to change the increments, from what I have read, which likely should have been a ini variable.

I've removed all the classic ladder and PWM statements from my .hal.

Thank you all who helped me : )

Use MDI and M3 commands to set the spindle speed directly.

Normally the correct spindle speed will be set by the G-code.

M3 S20000

I thought my first cut would be manual, but I used NativeCam to cut a pocket in a scrap of plywood.
It made chips! :woohoo:

Thank you again!
