Hi. I almost have this working, however I’ve not quite got the fine tuning down yet. I have a bunch of questions. I’m running a Rambo like @tailslide , with dual end-stops. At moment I am only working with x and y. My z seems to have a broken wire.
I am able to get the values from m119 but when I change the firmware values it doesn’t quite respond as expected. For instance, the dead band at ± 100 was very sensitive… I’ve tried increasing this a bunch but it doesn’t seems to be adjusting as much as I’d like so as to avoid those small off axis moves when positioning. How wide can this be?
Also should it stop and start or be completely smooth? If I push the stick full tilt too quickly it goes then halts. If I push slowly, it will mostly go ok. But still halts once in a while in travel. I’ve had to increase the over all range values (max and min) from what was recommended by @jamiek as well so that I could move the stick more freely, i.e. so it is not limited close to center. My range of values from M119 appear to be 0 (min travel) to 16378? (max travel). I expected to be able to go full on stick and have it run at its max speed but it seems to just stop. Normal?
Precision. Not really a joystick problem but it kind of stinks the lcd only reports X & Y at 1mm increments. If I drive to a location. Reset zeros (G92 X0 Y0). And machine something. If I later need to rehome for any reason (after disabling steppers for something) , there is zero chance I could return to exact same location. Best I could do is within .5mm. Better to use the menus.
Finally, I have found that it does not seem to respect the end stops (machine limits?). I can crash the gantry pretty easily using joystick. Should that be the case or is something amiss? I’m runnning dual end stop firmware. It seems this version of Marlin (downloaded in the last few days from V1 for this feature) does not handle endstops the same as my older version (downloaded last summer). In past version, when I home with G28 X Y, the coordinates X Y coordinates would set to zero. Does not seem to do that anymore. Could be why I can crash. Is this the new normal?
Sorry for long post. Any input is appreciated. Thanks.
