PWM Settings for Pokeys57CNC
« on: August 27, 2016, 03:10:53 AM »
Hi
First my english is not so good
Sorry

Mach3 Version latest
Pokeys57cnc V1.1
Pokeys Firmwar 4.2.6
Pokeys Plugin Version  2.0 (shown in mach3 start)


My Problem ist that the PWM Setting are working in Pokeys Software it self
When i move Slider for Pin17 the spindle goes from 6000 to 24000
all ok

but in mach3 the speed is alway the same at 6000
i setup the pokey plugin like ithe manual (https://www.poscope.com/wp-content/uploads/downloads/Pokeys/Manuals/PoKeys%20Pulse%20engine%20v2%20and%20Mach3%20plugin%20manual%20(6.3.2016).pdf)
page 24
pmw period 50khz
pin17 Fixed Duty Cycle in %
15%

when i set it to 100% it always runs with 24000
when i set 50 % it always run with 12000

but now response on the g-code or override from mach3

what is wrong
please help

As we responded in the support ticket, configure the PWM output to be mapped to a DRO in %, not a fixed value in %.

A fixed value setting will result in a fixed value on the output - this is useful for setting up LCD backlight and contrast, but it is not intended to drive a spindle with it...

Select 'Mapped to DRO in %, select DRO 817 in the list, configure the multiplier to 0.00417 (so that when spindle DRO reads 24.000 the result is 100) and check the check box below to turn off the PWM output when spindle is turned off.

Thx
but as i respond to the support ticket i already try your setting
map to dro in %
dro817
configure multipl to 0.0414 or 0.02
starting mach 3
load g-code with two tools

mach with says first tool 24000, spindle starts and run at 6000
spindle stops for tool change
tool two 13000, spindle starts and run also at 6000

no spindle override response

when i start polabs app parallel to mach3, go to pwm , pin 17, move the slider to 100%, the spindle goes up to 24000

what can i do
install mach 3 again over the existing installation ?
go back to pokeys 4.2.2 ?

thx

1. Never run any other application that accesses the PoKeys device in parallel with Mach3!
2. Check that the DRO 817 changes according to your code.

OK but it was the only way to test if pwm port works

mach 3 shows the right spindle speed
but the spindle runs only at about 6000

IT WORKS

I Reinstall the PC with Win7 and Mach3 and Pokeys
now the Pokeys Config  port Mapping look a little bit other then bevor

Bevor i have many Ports with Not available
Now there are more Ports where i can select or config

but i dont know why

config in 17 like bevor
config the axis like bevor

and now it works
maybe i must only delete the pokeys config xml file in mach3 and the result is the same

spindle override did not work
but thats not so needed



thx Peter

Hello

I test a little bit more
settings are
pin17, map to dro in %, dro817, 0.0414

pwm works with Pokeys Plugin v1
but not with v2 plugin

I try pokeys 4.2.6 beta and 4.2.6
both pwm didn't work

then I change the dll to v1 and all is perfect

are there needed other setting for v2

thx

The PWM has been fixed in the latest plugin release.

Short Update

Hello

Sorry but i am very angry
i test ´the v1 also unintentionally for the jog problem after long pausing or waiting
what i mean

i have a tilled project
120x60cm so aspire tilled the g-code
first part all thinks done
pausing for short tool change no problem
then go to safe z position

unmounting the workpiece set it to the second index pins clamp it
go to wc
say good night to my son
all that took about 15min

back to milling machine
load 2nd part of the workpiece
press start
spindle starts
move x and y to come to first location
stuck of first x then releas then second
thinks y is on position and destroy my workpiece because im not fast enough to get to the e-stop
and my z point has also moved

thats bull *********
the only think thats work after a long pause is to make pokeys powerless and also restart mach 3
and that i forgot this time
sorry but my gbrl card has not so many problems
i want a reliable milling machine
but i think i am the only one which use this *********
sorry for my words but when you lost a 80 euro wood plate because of this

i think when i have some money i change to smoothstepper
when  i took the money of the destroyed pokeys workpieces i already could  have buy one of this


sorry
