PoKeys / Pokeys57CNC Analog PWM Output to control Laser with M11P1 M10P1

« on: October 28, 2019, 10:37:35 AM »

Hi
Sorry if this is elsewhere answered but I really can not find it.
Like many others: Due to the slow reaction of M3/M5 I get darker dots when laser engraving with my OptLaser. I understand that I should change to M11P1 / M10P1 to solve this (or M11P# /M10P# instead of Pin 1).
But I can not figure out the setup needed in MACH3 and the Pokeys Plugin so that M10 /M11 rapidly controls on/off of the Analog/PWM out at Pin 17 of the Pokeys 57CNC. The OptLaser has only one control input for the intensity (0-5V ) but no separate on/off control input (then it would be easy)
Any hints are highly appreciated.

PoKeys / VFD RPM control wiht Pokey57CNC 1-10V output does not propperly work

« on: December 20, 2018, 12:07:46 PM »

Hello
Everything on the setup is working fine including. Hoever, one big problem is unsolved so far.
Maybe you can help me for this (Mach3, Pokeys57CNC, Fuling inverter DZB215DK)

The Pokeys57CNC will allow me to turn on/off the spindle with Mach3 via OC1 on the Pokeys which works fine. It also outputs exactly up to 10v on the 0-10V socket when not connected to the VFD. Looks good. Also masured at the VFD, as long as the VFD is not powered on. No shorts in the cables. Everything is fully shielded. The cable to the VFD is a LAN cable, twisted pair, each pair shielded and the whole cable shielded. Plus a Ferite at the end. So unlikely a noise problem.

Now: When connected to my VFD and after the VFD is turned on it will automatically draw almost 8V from the board (without an M3 command). The 10V shrink immediately to about 1V

I can't get an acurate speed on the spindle. When running can't get a speed over 8'330 rpm when set at 18000k. When it runs at this speed i measure 4.8V at the VI (PWM) input

The board is connected via VI and iGND. Pokey config according to Page 26 of the Polabs Mach3 plugin manual. Mach 3 is set to PWM control.

It's like the VFD is drawing in voltage, it's as if it needs a standard xxV then needs to be 'topped up' by the board. Every measurement I take from the board is several volts lower than the expected as soon as the VFD is powered on.

I've checked the board several times when not connected to a VFD and the output is as you'd expect at 0/12/24k rpm.

I have no clue where to search any longer.

I really appreciate any hint whre to search.
