I have some minor control over speed, an m3 s200 command gives about 600 rpms at the output shaft of the motor, a change to m3 s2000 bumps the motor shaft speed up to aprox 630 rpms . No great increase or decrease in actual rpm even with a huge change in s value.
The settings under the spindle tab are currently have use spindle feedback checked, closed loop spindle checked, spindle speed averaging unchecked
Use pwm is checked , pwm base 100, min PWM 10%
On the motor setup , spindle the pulse width is set at 1
When I type in m3 s200 (or any speed value) I get a message stating "PWM Bumped to Minimum"
On the spindle encoder issue , I changed the index pulse debounce to 8 and it seemed to level out. I choose the save config option on the pull down, shut mach down , rebooted the computer and the rpm readout now varries wildly from 50 rpm to 10k+ , it seems to change randomly while the spindle is off as long as the beam is broken, when its aligned with the slot in my disk and at rest for a minute or so it settles at zero.
I apreciate all the help, I am so close its driving me nuts
