General Mach Discussion / Re: Power Supply Question / Problem

Hi, olf20

The breaker may be weak or undersized and spiking due to in-rush & out-rush when the breaker trip's.

After the Power-Supply start-up/stabilizes, That's after the brown-out is over, lights back to normal.

How about a switch or relay to turn on your Drives & the 5 volt supply power.

Converted a bridge-port size mill with servos over to Gecko's with 75 volt power supply wired the relay to the E-Stop Button Reset.

Also depending on the size of your Capacitors maybe you only need one for needed filtering, That would decrease the in-rush time.

Not an expert hear.

Hope this Helps, Chip

Hi, Spiwrx

Sounds good, If Your Happy with the Speed, Lot's of figure's get bounced around on Stepper's

On the Y limit, Maybe a bad SW/Contacts, Some have put small .01 disk capacitors across the SW terminals, pull up or Pull down resistor's, Re-check the wiring, Swap the Switch's

around, or Let it work for a while,.

Are your SW's N.C. in Series  or N.O. in Parr.

If you have a O-Scope you should be able to track it down at some Point.

Have Some Fun Sounds Better, Chip

Hi, Wolf

Hear are a couple more features, Under "Operator" tab, Click on Auto Calculator, TAB key will bring out MPG Jog Pendent.

Enter 150 into FeedRate & 100% Slow Jog Rate in there Windows, Then Jog Mode to "Cont."

This set's Mach3 to max speed as long as your "Velocity" is 150 or lower.

Mach3 defaults to feedrate of "6" at start up, Causes lots of issue's when Tuning.

Just some More, Chip

Hi, Wolf

In Ports & Pins,First Page, Set it to Sherline 1/2 Pulse mode, Then re-start Mach3 and give it a try.

This will increase the Puls width more, Giving your stepper board moer time to see the pulses.

Thanks, Chip

Hi, Spiwrx

78 volts is at the top, But Mories at gecko drives, Sed there drives have 100 volt mosfet's in them.

Thy de-rate them so people won't use over 80 volts, Safety margin, And need a Good Heat Sinks.

That's 80 volts 7 Amp's, 560 Watt's, You would be at 80 volts 4.5 Amp's, Watt's 360

Rutex another MFG. Rates there drives at 100 volts, Thy Both use the same type Mosfet's.

If you don't have another computer to test then go through this Link.

http://www.machsupport.com/optimisation%20XP.txt

It describes things to turn off in windows, do some of the first items then re-boot and try the driver test again.

See if Quick-Time is installed, It causes problems also.

Thanks, Chip

Hi, Wolf

666mhz is on the low end for running mach3 any way, Lot's going on in Mach3.

What are your "Steps Per" set to in Motor Tuning, start at 200-400. set the velocity & Acceleration lower.

Also in Motor Tuning, Set the Step & Dir Pulse's to 5, See if that helps.

Let us Now.

Thanks, Chip
