Title: Spindle not running Properly
Post by: mhdale on March 15, 2007, 12:12:13 PM

I have just encountered a wierd issue, I think I have solved it but I wanted to make sure that I have and that it wont appear suddenly when it would be a ver bad thing. I was running my spindle warmup and I heard the spindle shutting down and restarting over and over again. When I checked the diagnostic screen I saw MACH3 was turing the output which controles the spindle on and off. I also noticed that the DWELL was active on my main screen and it should not have been. I checked my motor tuning settings and noticed that the settings for the spindle motor were set at the settings recomended by CNC4PC for the breakout board I am using. which needs the 35K kernel to actually run. So in order to obtain the 10V out with the lower Kernel speed I have my system set to because of other issues I need to set my Step pulse to 6. I have two questions, (ONE) is the step pulse width going to cause any issues with my stepper drives? I dont think so but I am not an expert, and secondly would having the spindle motor velocity out of bounds for the current kernel cause the spindle output to cycle on and off?

Thanks

Mike

The step pulse width of 6 is not going to hurt anything.

having the Vel out of the range for that kernel speed... That is bad and it will do many bad things :(
