General Mach Discussion / Re: E-Stop from high pitch?

Thanks, Would the best way to check this be to put jumpers on the limit and estop switches ? They are all normally closed switches.

General Mach Discussion / E-Stop from high pitch?

« on: December 12, 2011, 10:12:04 AM »

When I try to cut with a 1/4" bit it makes a loud high pitch sound and mach goes into e-stop.I can hit the reset and every thing works fine again until the bit touches the wood to cut.I just cut with a 1/2" bit with no problem. any thoughts??

Hood ,Thanks for your help. It was noise running back thru my auto zero wire.I disconnected it and didn't have any more problems.That's an easy fix with a plug.I left the filter values at 1.43,is that OK or should I try to go back to zero.I don't completely understand what they do . How does a higher setting adversely effect things.Thanks again,Tommy

when the limit switches are activated it would say so in the status bar.I have already removed the resistor and capacitor from the SS. I just thought of something.I recently added an auto zero plate .Could the noise travel thru the plate and wire to my bob and cause this problem.The wire from the bob to the spindle is shielded but the plate is not of course.I will disconnect the auto zero wire and try it .I am stuck in the office for awhile so I can't do it right now. Thanks,Tommy

I made a dry run,everything on but not cutting @ 1.43,no problem.When I started cutting the same problem. Then I changed the settings to 14.30,as soon as I cut the router on the SS quit communicating.I reset the SS, still @14.30,ran 1 part fine,by the time I put the next piece in to cut the SS quit again.Thanks,Tommy

 Hood, Tried that,they were all on "0" and I set them all to "1.43", and it still does the same thing. Thanks,Tommy

When it stops the status bar reads "external estop requested". I put a temp jumper on the bob estop connection, to eliminate a switch problem, and it still happens.

At first my  machine would loose communication with the smooth stepper and still does from time to time. Now i am having a new problem,the machine will stop moving for no apparent reason.I can hit reset and cycle start and it will start back up run a couple of inches then stop,this is happening very randomly . I would appreciate any thoughts.  Thanks,Tommy

SmoothStepper USB / Re: MACH CAN NOT COMMUMICATE WITH SS

I will double check all grounds.I know the difference between control ground and earth ground,but I could have made a mistake. I took the shield off of a USB plug and tried that,everything work for a few seconds then froze up,with a grounded power cord.I will get back to you with better documentation. Thanks,Tommy

Jeff,thought you may be interested in my outcome. The problem was not from the short.The problem was the new 110v wireing I did,which meant everything was grounded properly.when I plugged the PC back into an extension cord with no grond prong it started working fine again.Go figure.I have read about two different ground solutions,removing two little things on the SS or cutting the sheild off the USB plug.Any thought on this?
