PoKeys / Re: Pokeys and SERVO DRIVERS

« on: October 23, 2012, 08:00:46 AM »

Hi, Alex

Please take a look at the Pulse engine manual (http://www.poscope.com/productattachments/index/download?id=77). There are all pins listed.
For drivers that require 24V signals generated by open-collector outputs, you will need additional 74HC240 (inverter) and ULN2803 (open-collector driver).

Will check it next week when I'll have access to my machine.

Please export the PWM configuration and post it here.

Seldom

The DRO value gets multiplied by the multiplier, not divided by! In your case, the multiplier should be 1/40 = 0.025

PoKeys / Re: New Pokeys plugin MPG setup help.

Well, the PoKeys only overrides the Mach's MPG counters if you configure it to do so (select and map a encoder to MPG).
Apparently, kflop does it constantly and overrides the values that are sent by PoKeys plugin. As I see it from the aspect of the PoKeys plugin, PoKeys can't do it if someone else is overriding it.

Hi, Seklom

The PWM settings for PoKeys devices offer a wide array of possibilities and may therefore seem not clear at first.

PWM works by comparing a counter (running at 25 kHz) with a predefined PWM period value and resetting to zero when the counter reaches the PWM period. This defines the frequency of the PWM signal. In PoKeys devices, this frequency is adjustable and is shared among all PWM outputs.
Besides comparing the counter with the PWM period, the counter also is compared with PWM duty cycle for each output separately. The ratio between PWM duty and PWM period is usually called PWM duty cycle and is specified in %. 100 % means the signal is on all the time, 0 % that the signal is off all the time, while the 50 % means that the signal is on for half the PWM period and off for the other half.

So, why is there option to map the PWM output to 'DRO' only and to 'DRO in %'? The first option defines the value for the PWM duty directly and user must take care that the value is in the range from 0 to the value of the PWM period. 'DRO in %' simplifies this by expecting the DRO value from 0 to 100.
Because the user has usually no control on the range of the DRO values, we introduced a multiplication factor in the latest plugin release that allows you to multiply the DRO value by a custom factor, producing a value in the range from 0 to 100 for 'DRO in %' mapping.

PoKeys / Re: OEM Button 186, Select Y axis for MPG1 not working

Hi, Friedrich

We will make sure that disabling the button in the settings really disables it. It should already...
Which PoKeys device are you using? PoKeys55?

Hi, Friedrich

Please download the latest PoKeys beta software, which includes the latest Mach3 plugin. We tested it on our machine and it works as intended.

PoKeys / Re: Two buttons doing same thing, possible?

« on: September 30, 2012, 06:44:14 AM »

There is a simple fix. Use the 'inverted' option in the mapping settings. It will also activate the function as soon as you depress the button (assuming you have connected it between PoKeys pin 38 and GND).

Hi

We will check that and make it work. Both should work, but they might be 'fighting' each other at the moment.
