General Mach Discussion / Re: encoder resolution with stock powertron servos

« on: December 02, 2014, 02:00:55 PM »

Im using the cncdrives  DG4S-16035 with a 82 v power supply.

The reason I ask is my PID tuning is off a little and I cant get it right on the money.

So I'm thinking the brushed motors are having trouble making those last small moves.

For instanced I ask it to go 1000 pulses it goes 1012 pulse.

I don't know just thinking out loud.

Thanks john

Would make a nice case or case halves if you could get a real phone inside it.

Willing to share the code?

thanks, john

General Mach Discussion / encoder resolution with stock powertron servos

« on: December 01, 2014, 01:33:50 PM »

I have the stock Bridgeport dc servos on my machine.

The stock encoders were 250 ppr

my new ones have are adjustable up to 2000 ppr.

Is there a setting that works best with the older Bridgeport dc servos?

Is  there a setting that works best for Mach 3

Thanks, john

Should i buy the mach 3  now or wait for 4?

What is actually the difference?

It says that 3 will be discontinued?

My conversion is almost finished.

Thanks, john

Will a USB to serial adapter work with the Modbus to the motor drive or do i have to have dedicated serial port on my mother board?

thanks john
