PoKeys / Firmware problems 57E
« on: October 18, 2014, 04:49:29 AM »
Hello

for a few days i try to get my Pokeys57E working with my mill for step/dir generation.
I´m using the latest Mach3 full version on a new installed 32 bit pc running Windows XP.
The Pokeys is directly connected to the PC. My breakoutboard is from benezan-electronics and my drives are diy servodrives.
My drivers worked properly connected to the printer port, but sometimes Mach3 lost a few steps.

So i decided to switch to Pokeys and the integrated 3ch pulse engine.
But i had a few problems:

Using the latest version (3.1.38) my motors start moving when i start mach3. I can jog my axis with the keyboard, but Pokeys always wants to drive all 3 axis in one direction, even if the RESET Button in mach3 is pushed and the charge-pump function of my BOB is disabled - otherwise charge-pump function works fine.
Shutting Mach3 stops my motors spinning. Using the testfunction in the Pokeys Software everything is fine.

Then i went back to version 3.1.17 .
Here i got the problem that jogging by keyboard/gamepad, or starting the automatic homing function, is very slow (about 0.1% of my choosen max. speed). If i home the axis manually and jog my machine using g-code commands - the used speed is as fast as i choose in my gcode. I tried different changes, but without success.

At least i installed version 3.0.65
With this version jogging works well, but when i start automatic homing, the procedure is started and looks like everything works, but mach3 doesn´t recognize that my axis are homed. Ok i set my axis manually and tried a piece of testcode, then i saw that i got missing steps. (it has to be a controller-problem cause i use servo drives). And the charge-pump doesent work.


Hope someone can help me with my problems or give me tipps solving my problems with Pokeys.
Meanwhile i have to switch back to the printerport -.-
