General Mach Discussion / Re: Set up steps on Bridgeport Series II NC

Yes, 18.75 IPM is the fastest it will run.
What is the kernel and why does it change the velocity?
it will be Monday before I can try.
Thanks

General Mach Discussion / Set up steps on Bridgeport Series II NC
« on: December 31, 2014, 11:20:02 AM »
Need help setting up motor steps on a Bridgeport Series II NC.
I used gecko drives with Mach 3 software using the existing
Superior Step Motors.
To get to run one inch I had to put in 80,000 steps and
the fastest I could get it to run was around 20 inches per minute.
It seems to be microstepping.
Would prefer it to step .001" instead of .0001".
I have set one up before and I used 2000 steps and got 120 ipm.
This one won't take it.
What am I doing wrong.

General Mach Discussion / Re: M3 Relay output from output 1

Yes, have tried it both ways.
Will try the advice that Tweakie sent about hooking
up the relay in series with the collector of the transistor.

I may not have enough power to turn on the relay. 
Thanks

Under config
Ports and pins
Spindle setup
Relay control
Clockwise (M3) output 1

Then under Ports and pins
Outputs
Output #1   enabled  port 1  pin1  Active Low

With no load on pin 1 I get 4.5 volts  when I type M3
and when I type M5 I get 0 volts
When I hook up a 5 volt relay it won't trip the relay

Thanks, I'll try that next week

Thanks it will be the end of next week
before I can try this.
I tried to hook up this optoisolator board
https://www.sparkfun.com/datasheets/BreakoutBoards/Optoisolator-v12.pdf
I put pin 1 to input 1 and ground to to pin 18 from the LPT
then put 5 volts to HV and hooked the 5 volt relay to output 1
and hooking up all grounds together. All I got out was .05 volts with M3 and .01 volts with M5
What did I do wrong?

I have my ports and pins set up.
Under ports and pins enabled pin 1 at port 1 enabled high
I get 4.5 volts out at output 1 (pin 1) with M03 and 0 volts with M05
with no load.
So the pin  1 works. I just can't get it to trip a 5 volt relay. I have tried
a 3 volt relay, a sold state relay ans an optoisolator and can't get to trip.
My outputs to the three drives works fine and the control runs programs.
My E-Stop input works fine. I tried different outputs, pins 2 and 3 and
can't get them to work.
Thanks if anyone can give me advice.

General Mach Discussion / M3 Relay output from output 1

Trying to get a relay to turn on for M3 out of output 1
I have turned on in config and spindle.
Metering between pin 1 and pin 18 gnd I get 4.5 volts to gnd
when I input M3 and it goes to 0 volts when I input M5.
 When I hook up a small 5 volt relay it reads 3.2 volts and toggles to
0 volts. The relay does not pull in. Tried a 3 volt relay same thing.
Then tried a 3 volt solid state relay and the relay did not pull in.
Then tried an optoisolater board from Sparkfun. The voltage toggles
between 2.2 volts and 0  with 5 volts hooked to the output side
all I get is .005 volts to .001 volts when I toggle.
Also I have pin 18 tied to machine ground and the 5 volt ground.
It is like I'm not getting enough amps out and loading down the circuit.
What am I doing wrong?
