Jerk and acceleration settings cr-10s5
-
Well not much left to do but tweek my settings.
I've been reading up on both and unfortunately dont have A clue where to set this stuff. The settings have never been played with and i am curious whether this is default or was imported " somehow "
Jerk is set at 10, and acceleration at 10,000. ??? What happens when you drop it and what happens when its raized lots of info on where they set it but not why or what it does it improve when droped???Second when I home. It stops half way. Although the size is set at 500mm in my config file.
Last. Ever since i instaled and abl bed sensor my end stop sw.fail to stop the carraige and slames into the y and x axes. It now does not see the end stops althou they function the led on the duet i suspect when i followed the online instructions steps got missed or limets not chainged ?????? How should i aproch approach this. thanks -
Please post your config.g and homing files.
-
Take a bit need to teach my self how. But will do tonight. thanks

@ziggymanpopo said in Jerk and acceleration settings cr-10s5:
; Enable Bed Leveling
G29 S1 ; Enable Mesh Bed LevelingYou should probably move this to the end of your homeall rather than the end of config.g. Having it enabled as soon as the printer is turned on means that you haven't yet defined where Z0 is, which can lead to frustrations with first layers.

G31 P500
Try G31 P25 instead for a tighter trigger threshold on theBLtouch.
@ziggymanpopo said in Jerk and acceleration settings cr-10s5:
M98 Pdeployprobe.g ; deploy mechanical Z probe
M98 Pretractprobe.g ; retract mechanical Z probeYou don't need to manually deploy or retract the pin. The Duet will do that on it's own as needed for probing.

Z jerk may be a bit low for mesh bed leveling. Try Z60.
E jerk is bit low at 300, especially if you intend to use pressure advance. Try adding an order of magnitude, 3000.
X and Y acceleration are a bit low. 600-900 for X wouldn't be too crazy. Given the size of the Y axis 600 would probably be appropriate. -
Yeah prob. Should have mentioned that i have an abl inductive sensor not a bl toutch ,, so i believe the person who helped me with the original files picked a generic file just to get me going. So fare so good but i have some serious clean up to do not sure where to start except "one thing at a time. " just like any kit printer i realize my learnig curve the printer has some issue because of the board configuration and the printer are not quite a match or set right. i will take one ore two items at a time . The info has been invaluable. And i think this will keep me focused i thank all for there input
-
What is causing ghosting and ripples in the y axes ...its just in the y ??? Does it have to do woth the weight of my 500mm bed... Also if i turn up any settings won't it hit the end stop harder ...what in the setup made the end stops no longer function. Should i chainge it back so they do and will this stop hard hits when homming

It's stopping halfway because you're only moving half the distance of the full bed size. Increase those movements to more than 500 to ensure they hit the endstop.
I didn't realize you were not using the BLTouch. If the probe is working, leave the settings as is and disregard my comments.
If you're still getting ringing even with those conservative values I would look at belt tension and flex. Such a large and heavy bed is going to be difficult to tame.
The speed of the homing moves is set in the homing files. Since you're using sensorless homing you must use a fairly rapid move for the stall detection to trigger properly. Personally I'm not a fan of the idea of slamming my print head into a physical stop to home, but it seems to be all the rage these days.
-
I agree??? slamming is no good. Is there an easy way to put endstops back in play ??? Did that happen when i activated the. Abl sensor in the gcode??? Is it advisable to reactivate the end stops...When i set up the board they worked ??? The second problem i have is with the stall feature is when it is at the home on x,,, and its not on home for y ans z . It makes an auful sound on x when homming y and z . "The rest of the way." "like when an print is done"it homes y and z... but x isballready homed.... So it grinds x because its allready homed....then it homes the other two. Any hints highly appreciated
-
Would it be possable to increase the size of the belt to aid in the taming of my large bed. ???
Id thought about putting in linear screws and guides. as a solution for the y axes -
Well if the end stop switches are still in place and connected to the board you can change the config to use those instead of stall detection.

Id thought about putting in linear screws and guides. as a solution for the y axesLarger belts may help for belt stretch but so would higher quality belts. It still doesn't reduce the weight of the bed though.
Linear screws have their own rotational momentum to deal with so aren't actually a solution. You'd be limited to the same or lower acceleration.
