Auto Level Question/Issue?
-
in the "settings" tab - under "Machine Properties" shouldn't all 4 z motors be
listed there? -
is the location of my m671 command in my config.g file in the correct location I do have it after the m669 and m667 but....
-
I found the problem. Stupid user error... I've been battling with this past 3 months.....
M671 X:-150:-150:800:800 Y-10:850:850:-10 S1
I have a : in front of the x axis coordinate X:-150
Ugh...
But Thank you very much guys administrator and Phaedrux wouldn't have been able to figure this one out without you guys.
-
also one other question should I have
M92 X160 Y80 Z1605 E418 ; Set steps per mm
or should I have this
M92 X160 Y80 Z1605:1605:1605:1605 E418 ; Set steps per mm
with the same idea for all parameters with z axis movement settings with-in config.sys

correction config.g

ALSO one other thing now when I run g32 I get the leadscrew adjustment made
but I am not able to see a heigh map from the gui.?? -
Do you mean g29?
Can you view the height map in the DWC?
-
You need only one Z motor current in your M906 command. It will be applied to all the Z motors.
To generate a height map, you must run G29.
-
yes I do have the height map with g29 thanks again guys

a finished print, in case any one wanted to see it.

On another note, I"ve started printing a low poly waitier hands. ANd am seeing a lot of ringing and cannot eliminate it no matter what I try. I did notice it on my t-rex from MakerBot which scaled and printed beautifully, but because there were many small curvatures the to form the skull ur not able to see them as clearly. But they are there, visibly. some pics of the ringing with the low poly waiter hands. any advice, I've played around with jerk and accelrations and speeds from 50mm/s-200mm/s. and cannot get rid of the ringing.

@jkdp said in Auto Level Question/Issue?:

That is massive! What are you going to do with it?
-
@jkdp have you seen the release notes for 2.02 beta?
https://forum.duet3d.com/topic/6405/new-beta-firmware-2-02beta1
Dynamic Acceleration Adjustment (DAA). This is an experimental feature that adjusts the acceleration and deceleration of moves independently, to minimise excitation of mechanical resonance at a specified frequency, thereby reducing ringing. By default this feature is disabled. Use the M593 command to enable and configure it.

haha, not much building the machine and testing, and calibrating it for resale purpose. Ive had a few request here in Toronto locally and have build a few small machines, But this has been a crazy 8 month battle from design to build. But looking good now... finally.... Larger machines are soo much harder to calibrate than smaller ones I've learnt, but think I've got the hang of it, besides this ringing...
NO in regards to the notes I will look at them, right now... and report bak, you guys are quick with the responses I really appreciate it....

You might find some more details here.

ok I played with my jerk and acceleration settings more and got not much of a visible difference, if anything. I downloaded and Installed the new firmware and am noticing a lot less difference at higher speeds than slower now just to fine tune it. Any advice ??
-
I'd suggest a systematic approach. Prepare a sliced gcode file to test with. A tower of some kind with sides long enough to get up to your chosen speed. I like to use 100mm/s so that it's easy to scale the speed with percentage. Use 2 or 3 walls and no infill. Make sure your slicer doesn't try to control acceleration settings. Set jerk to something easy like 600mm/min (10mm/s) Then use the m204 gcode command to modify the acceleration for print moves increasing every 10 layers or so. You could even add it to the gcode file itself so you don't have to do it manually. Then print it a few times at different speed factors and you should be able to identify a sweet spot. You could also measure the distance between ringing ridges and use the formula from that thread to find your ringing frequency.
