DEAR DARELL
AS YOU MENTIONED IN YOUR MAIL YOU PLAN TO USE ENCODERS AND SERVO'S
THE CARD YOU MENTIONED HAS AN 8254 [PGM TIMER]
I TRIED USING THE CARD WITH STEPPERS THE CARD SEEMS TO WORK OKAY.
THE MINUTE YOU USE A SERVO SYSTEM AND TRY TO THREAD THE CARD GIVES UP. AT AROUND 1100RPM OF THE SPINDLE WITH A 1000PPR ENCODER [WHICH IS NOT TOO MUCH OF RPM OR PPR CONSIDERING FEEDS AND SPEEDS USED TODAY]INSTEAD OF PRODUCING A DECENT STEP SIGNAL WHICH WOULD BE USED BY YOU FOR A STEPPER OR SERVO THE OUTPUT WAS GARBAGE WHEN LOOKING AT IT ON A SCOPE.
AS THE SERVO/STEPPER SYSTEM SEE'S NO PULSE YOU
FURTHER THE COMPANY DOES NOT HELP OR ASSIST YOU CAN CREATE ENDLESS SCRAP AND BREAK EXPENSIVE THREADING TIPS/HOLDERS..
I PLAN TO RESEND THIS EMAIL NOW THAT I HAVE FOUND IT FOR YOU. OPP'S THE MILLENIUM HAS CHANGED !
REGARDS
BYRON

copy of email dt.19\12\98
SENT TO MICROKINETICS NO REPLY TO DATE. THERE WERE PREVIOUS FAXES TO THEM NO REPLY
WE HAVE PURCHASED 2 OPTIPLUS CARDS FROM YOU IN THE PAST AND FACE THE
FOLLOWING
PROBLEMS
1.]THE DRIVERS SUPPLIED BY YOU FOR USE WITH TURBO C++ CANNOT BE COMPILED
USING LARGE OR HUGE MEMORY MODEL AS THEY WERE COMPILED UNDER SMALL OR
MEDIUM. ARE YOU IN A POSITION TO SUPPLY THE CORRECTED DRIVERS AS WE HAVE
FURTHER REQUIREMENTS
2.]ON THREADING THE ENCODER INPUT FREQUENCY ACCEPTABLE BY THE CARD IS VERY
LOW. ie.1000PPR ENCODER CANNOT TRACK THE SPINDLE CORRECTLY AT 1000RPM. IS
THERE A SOLUTION TO THIS AS WE CANNOT THREAD AT 1500RPM WHICH IS OUR
REQUIREMENT
3.]YOUR MILL MASTER PRO DOES NOT INCORPORATE TOOL OFFSET G40 G41 DO THE
NEWER VERSIONS HANDLE THIS ?
MERRY X'MAS TO YOU
REGARDS BYRON
