Again Pokeys57CNC problems, anyone using it?

[assadi]

Hello, I bought the pokeys57cnc and Postep60-265 drivers, a plan to use them for plasma CNC , does anyone use this board for plasma machine ?! The THC I plan to use is miniThc from Russia, it have parallel connection ... As I understand I can connect the parallel THC to pokeys57cnc with IDC26-to-DB25 ribbon cable, but in which port exactly on pokeys57cnc on the one listed db-25 connector with 5 end switches ?!
Appreciate help and suggestions.

As you see above improper? grounding or just EMI from servos messed things up with my board and it was doing strange things. Make sure you properly isolate it from noise, cables included.

About the parallel, its in the manual i believe.


Take a notice what they say there page 16:
DB-25 (LPT-port) IO connectorWarning: on PoKeys57CNC v1.1 the pinout is not compatible with the LPT-based stepper drivers sincethe physical pin numbering sequence in PoKeys57CNC v1.1 differs from that of a real DB-25connector. Check the pinout diagrams above.

I have been using it for more than a year, what do you need to know ? perhaps i can help

i now plan use it first time with mach 4 with new cnc from china
i already bought all parts and take them with me to china
next month ill be there to test on machine
first question is about stability, i use spindle ,3 axis ,magazine with servo motors ,drill head with 12 tool s on it
i plan use the pokeys57 with 5 relay cards and use all optional inputs
most i fried is from noise and stack machine
second is very strange to me is that there no input for encoders to controller ,that mean even i use servo motors ,the encoder input only to the servo motor driver ,and not any conection to mach4 to see real position
thks

The only low cost controls that can run in true closed loop are LinuxCNC, and Dynomotions KMotionCNC.

[yaakovKatz]

do you have experience with Dynomotions KMotionCNC?
do you think its batter then mach4?
is it so flexible and can manage like mach4?
thanks alot

think i have read somewhere that pokeys57cnc can use encoders on servo's.. but not sure
