I am in the process of setting up a 4 stepper gantry machine (XYZX). I started off using the stepgen and slaving the axis... this appeared to work.
This stepup: Used the gecko 540 selection (i have the 251 which are the same) to get the correct steptime, stepspace, etc. Got a base period of 65449 in my INI. (My jitter is at about 45000) Scale is 1909.9 steps per inch hal looks like this for the X and Y motors setp stepgen.0.position-scale [AXIS_0]SCALE setp stepgen.0.steplen 1 setp stepgen.0.stepspace 0 setp stepgen.0.dirhold 45200 setp stepgen.0.dirsetup 45200 setp stepgen.0.maxaccel [AXIS_0]STEPGEN_MAXACCEL net xpos-cmd axis.0.motor-pos-cmd => stepgen.0.position-cmd net xpos-fb stepgen.0.position-fb => axis.0.motor-pos-fb net xstep <= stepgen.0.step net xdir <= stepgen.0.dir net xenable axis.0.amp-enable-out => stepgen.0.enable Now what I want to do is use gantrykins so I can home my X joints separately. I based my config off of the stepper-gantry in the config. I got it to run... but when I increase the speed on the X or Y axis EMC will show it moving faster. But the motor will be running slow (like it is missing steps). This happens around 250 in/min. Slaving the Xs together I ran it up to 480in/min Any idea would could be the issue? I attached those hal and the INI files. Not sure if you attach files to the list?
