I have a CNC4PC C1G parallel port interface card driving a Gecko 203v. I have a 28vdc power supply and I am running the stepper without any load just to get my configs setup... The highest velocity I can get is about 70 as reported on the Axis screen no matter what I set F at. If I do a MDI G1 F100 X10 or G1 F400 X10 I get the same velocity reported of about 70.
If i do a G1 F50 X10 I get the expected velocity of about 50 If I do a G1 F25 X10 I get the expected velocity of about 25 I've ran the latencey test on the machine and used the spreadsheet to figure out what to set the base period at. My config is: BASE_PERIOD = 15000 DEFAULT_VELOCITY = 0.0167 MAX_VELOCITY = 7.0 DEFAULT_ACCELERATION = 15.0 MAX_ACCELERATION = 20.0 My Axis is: MAX_ACCELERATION = 2.0 STEPGEN_MAXVEL = 7 STEPGEN_MAXACCEL = 2.1 BACKLASH = 0.000 INPUT_SCALE = 3000 OUTPUT_SCALE = 1.000 MIN_LIMIT = -100.0 MAX_LIMIT = 100.0 FERROR = 0.050 MIN_FERROR = 0.010 When I run tests the drive turns the correct number of turns per inch (1.5) so I'm reasoning that I have the scale correct... Any tips on where to start looking would be a big help... Thanks John ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
