Duet 3 - Moves really slow?

Martin1454

Also - I use 0.9deg steppers fyi

Veti

i cant spot anything wrong.

are you on firmware 3.1.1 (check with m115)

Phaedrux

Is 30% current too low?

Does it move correctly outside of the homex?

Can you post the results of M122 and M98 P"config.g" ?

my old setup worked fine on 40% - I have tried 30,40,70 and 100% current

I cant tell if it moves corretly, since I cant move it before homing it first.

Send G92 X100 to set it's position to 100 and flag it as homed. You can then jog the X axis as normal.

dc42

I didn't spot anything wrong either. Please send M92, M203 and M350, all without parameters, and check that the values reported are as set in config.g.

Martin1454

@dc42 said in Duet 3 - Moves really slow?:

M350

So this looks like there is something overwriting my settings on the m203 - gotta dig into that I guess.

Edit: Non of my gcode scripts contains the numbers 140

If i send G92 X100 and then jog it, it seems normal, but as soon as I press homex it vibrates the motors for like 1 second, stops and then moves slowly towoards home.

@dc42 Do you have any idea why it shortly vibrates before doing the homing move?

Veti

send M999 and redo the steps

droftarts

@Martin1454 M203 in config.g is set in mm/min, but reports in mm/sec. 140mm/s is the same as 8400mm/min.

gets me every time

are the movements also slow if you do manual movements via g code?
i.e G0 X50
to
G0 X150

Phaedrux

Are you sure X Y steps per mm is 200? If you command 100mm of movement does it actually move that much?

Moves a little bit slower than jogging, but still way faster than when homing

Yes, it moves excatly 50mm when I jog it 50mm

Moves a little bit slower than jogging, but still way faster than when homing

and when you issue this command on its own.
G1 H1 X-325 F4000 ; move quickly to X axis endstop and stop there (first pass)
?

Phaedrux

Can you add M400 before your M913 commands to change the motor current?

It steps 1 step towrds -x, but not 325mm

I did now - still no change

I'm not sure what you mean by that.

Can you post your current config.g and all your homing files? bed.g if used.

Jogging moves will happen at the defined feed rate in config.g unless otherwise specified with an F parameter.

The feed rate of the homing moves is defined in the homing file, so jogging and homing is going to look different unless they have the same feed rate specified.

Martin1454

@Phaedrux
The stepper takes 1 step - like it moves to the left a tiny bit. (I think 1 full step, not microstep)

That sounds like stall detection has triggered prematurely. Does it show the axis as homed after it stops?

I guess I'm a bit confused, is it a case of movement being slower than requested or is it stalling before it should?

Have you gone through any of the stall detection tuning?

@Martin1454 Can you post your homeall as well if you're using it? Or are you only testing home x at the moment?

Mostly just curious to see if there are any other gcode commands being executed to change the values between config.g being executed at startup and when executing homex.

Thats what im trying to do - Im trying to setup the stall detection, but I never get it moving fast enough to try to tune it.

But Maybe I should try to add in a comment it post when it triggers, and see if it triggers prematurely and that is why it vibrates/stalls in the begining.
