Hi newbie,
After pressing Estop the spindle speed is cancelled.
Pressing [Spindle CW] without issuing a new spindle speed will only output a few milli-volts.
This is not the correct way to restart after an Estop.
Either rewind and start from the beginning or use Jump to line.
I do not understand why you cannot get the spindle to run now.
Just to confirm that when you are testing the voltage on Spindle pin 1 you are issuing a speed command either in MDI S18000 or by entering speed 18000 in the box as shown in the video above before pushing the [Spindle CW] button. If you do not issue a speed command the speed will be 0 and the reading you get will be in the mV range.
This may help with understanding how to use the jump to line feature.
In the video it shows how to save the work offsets but that is now automatic so ignore that part.
If you have a power cut in the middle of cutting just home and the jump to line will show the last line that was machined.
Cheers Peter
