@alankilian ok i will remove it. Thank you very much 🙂

Because of this abnormal and unexplainable thing i could not sleep anymore. I deassembled my effector and found the reason: when i put the heatsink back into the effector hole i not watched careful enough to my hot end fan wires. Therefore i clamped the black wire between the sink and the effector plate. OMG 🤦🤦🤦

Because of the elasticity of the isolation i got a different trigger height. Now i get my old trigger height. Reason found and explained. Now i can sleep like a baby again 😄

no i use the stock smart effector values. I think you forgot the macro or i am blind? 😄

@engikeneer thank you that sounds great. I am from germany

i meant the sensity parameter for smart effector:
M672 S105:70:185

try this. it should fit

@PuddingBaer91 Is X0 Y0 (bottom left corner) where the X and Y endstops are triggered? So the nozzle is -25mm off the bed in X, and -15 off the bed in Y? And the nozzle can't reach the last 15mm of bed in Y? If so, your M208 commands should be:

M208 X-25 Y-15 Z0 S1 ; set axis minima M208 X330 Y315 Z350 S0 ; set axis maxima

This would limit the nozzle to being within the bed area. With your probe offsets, X-35 Y20, the probe can reach X0, but only 330+10-35=X305. For Y, it can reach from -15+20=Y5 to the nozzle maximum, at 330-15+20=Y335. This would be off the bed, so can just limit that to 330. Then take all of these, and add a 5mm safety margin to get:

M557 X5:300 Y10:325 ; probe points 5mm within axis limits

Your M558 command indicates that you have a BLTouch. You should remove the M98 Pdeployprobe.g and M98 Pretractprobe.g lines. Also, check that your deployprobe.g and retractprobe.g files are set up correctly for BLTouch.

@dc42 said in M204 and pressure advance and travel acceleration?:

@PuddingBaer91 said in M204 and pressure advance and travel acceleration?:

I want to optimize the print quality. For this i reduced the acceleration given in M201 to 800mm/s^2. But i also want to have high speed travel moves (200mm/s). For this an acceleration of 3000mm/s^2 would be better...

Can i set the Travel acceleration to 3000mm/s^2 with the M204 command to reach this goal? (Have slow print accs while having high travel accs)

That's the wrong way round. Set the M201 acceleration to the highest value that you ever want to use. You can reduce and printing and/or travel acceleratoinit for particular prints using M204.

ahh okay i think i got it. Now my settings look like this:
M201 X3000 Y3000 Z100 E10000 ; Set max accelerations (mm/s^2)
M204 P1500 T3000 ;Set accelerations for print and travel moves (mm/s^2)
correct?

I still can't use pressure advance and still wonder why others using e-jerk values about 3600mm/min. If i do this the BMG will make bad noises. (e-acc is 3600mm/s^2; PA=0.4) If i lower the e-jerk to 120mm/min the print speed will slow down also the effect of PA is gone because the speed at corners will be so slow...

Try reducing E acceleration. is it a genuine Bondtech BMG?

yes it's a orginal BMG with 80-90cm bowden tube. Already tried to reduce e-acc but doesn't help. I tried with 3600 for jerk and 3600 for acc like others using with good results... but mine sounds not good so i won't use PA

If i put M204 in the console after a emergency stop (clean load of my config.g) it will return:

M204
Maximum printing acceleration 10000.0, maximum travel acceleration 10000.0

But in my config.g there is no M204 defined.

Those are the default values, designed to have no effect because they are higher than normal M201 values. the actual acceleration will be the lower of the M203 value and the M204 value.

Note, if you are using dynamic acceleration adjustment (M593) then you should not normally use M204 to reduce accelerations.

don't use dynamic at the moment

thank you for the help

thanky you very much. I replaced the cables and now it works but also good to know how to check faulty motors. Thank you

i only testing so if i set PA to 0.1 it already doesn't work anymore

edit: if i set the extruder acceleration very low (100mm/s^2) it works better...

edit2: with these settings it works but for jerk 3600mm/min never ever

M566 X1200 Y1200 Z100 E1000 ; Set maximum instantaneous speed changes (mm/min) M566 X1200 Y1200 Z24 E300 gut: M566 X480 Y480 Z24 E300
M203 X50000 Y50000 Z450 E3600 ; Set maximum speeds (mm/min) M203 X18000 Y18000 Z2400 E2700
M201 X1000 Y1000 Z100 E3600 ; Set accelerations (mm/s^2) M201 X3000 Y3000 Z100 E3000 gut: M201 X800 Y800 Z100 E3000

thank you very much. I can confirm it was only a repeated message. It works very well. I LIKE MY DUET 😉

I am using firmware version 2.02RC2 (RTOS) (2018-09-07b2)

HAHA guys i found the problem i can't believe: I used the wrong motor directions so nothing worked logical, minus were plus and plus were minus Hääää??? oh my god 😄 now it works like it should.
