PoKeys / Re: PWM output for Spindle
« on: October 19, 2012, 08:14:43 AM »

stupid, it was me.....thought i was fully up do date but i had to update the firmware on the pokeys....

now it work like a clock with the same setting only multiplier 1

sorry guys, (should have checked it)

I am not smart enough for this..

to be sure checked again pin 17: fixed PWM at 50% works as a clock.

and then...in PWM tab...pin 17.... Map to DRO in %         DRO 817: Spindle request DRO   Multiplier 0.01   pulley 0-100

when i open Mach3, pin 17 : 0-VDc, as soon as i enter a value in the box "Spindle speed " pin 17 goes to a stable 2Vdc no PWM signal at all,
closing mach3 en restart Mach3 again is the only way to get it back to zero again.

Tried a dozen DRO en multipliers, so it must be something else.

I just want to select the PWM duty cycle signal that mach calculates ?

thanks

Matevž,

Thank you for your clear explanation. This give a bit more understanding than the manual.

to give it a test:  So If i want to get a 0-100% PWM signal on my pin 17 i have:
For example : Pulley 0-4000rpm => PWM 0-100 =>multiplier 40 so if i set 2000 RPM my PWM should be 50%. But not in mach3:

1) map pin 17 in %
2) select the correct DRO : DRO#817: "Spindle requested DRO" ?
2) find its range : assume 0 40000 assume
3) divide the range to correspond to to 0-100%: assume 40

so if we insert 2000 in the MDI it should work...lets try tonight

Is it this straightforward or should this be in a brain

thanks..

PoKeys / PWM output for Spindle
« on: October 18, 2012, 03:57:59 AM »
Gents,

Pokeys56U running fine, in and outputs are working fine, but i want to use the pokeys to output the PWM signal to drive the spindle frequency converter ( 0- 5 Vdc ). It would be nice to get a 10kHz PWM signal instead of the  mach3 PWM signal of 200Hz.

Opened the pokeys configuration, PWM tab, selected pin 17..... then you have to make select a DRO that i can guess but are not clear to me. Ive tried 10 or so but no result.  I guess i have to select the option "DRO in %" first and than the right DRO that sends the % PWM to the output ?

(Ive tested the PWM signal on the scope and in the "fixed" setting it worked) 

what am i missing ?

Thanks,

PoKeys / Re: Mach 3 setup with Pulse engine

 :D :D :D :D

it works... great.  I have increased the time out, and again looked closely at the ip setting, made them fixed and it works like a clock.

Thanks for the support...we keep enjoying mach, and pokeys

Yes, i have a scope and i will try,

However in the mach-3 screen the axes coordinates to not change, they simply do not react to the jogging command from the keyboard,(If i switch to LPT port device this works fine)

Question: When you disconnect the pin 52 while jogging do you get any notice on your screen, like the E-stop or something? .....Because nothing happens on mine. So i suspect it's a communication thing.

yep pin 52 is connected to gnd.

the strange thing is that the motors run using the pokeys software but in mach-3 jogging is not possible.

hmmm

 re-installed everything, but still nothing, pokeys is not communicating with mach 3.

I already reset pokeys...but somehow i never get back to where i have to fill out the activation code etc.... somewhere pokeys stores the setup files but i cant find it.

is the old mach3 plugin for the 56E still available, so i can test if that still works for the in-outputs...

Neo, thanks for your reply;

yes - pokeys device setup through the plugin > config restarted
yes - external motion controller popup came up and ive selected pokeys

In the pulse engine manual it than states motor config > as normal,
... so i assumed you have to select Ports/pins > and enable x,y, and selects port (10) and pins (38,46) in the Mach 3 menu...


i tried to do a clean new installation and start al over, but it seems hard to get rid of all settings files.
