Are you certain that setting nonzero extruder pressure advance in M572 is causing a problem? Also, have you checked on the web interface or by sending M115 that you really are running firmware version 1.15e? Firmware updates do fail sometimes.

No Actually, it just helped. Things started working right when i put the M667 S0 and the M500. I can set the M572 D0 S0.00 to something other then zero. Whats a Recommended value to start with?

guywinslow · 16 Oct 2016, 02:50

oww, yes i am running firmware version 1.15e. At least that is what the web interface reads out.

Try S values between 0.05 and 0.25. If you are using more than about 2mm of retraction then be prepared to reduce it when you use high S values. For example, using S0.25 will add about 1mm of retraction at the end of a fast printing move.

guywinslow · 17 Oct 2016, 02:39

Ok, i set the pressure advance to this, and started a test print
M572 D0 S0.05 ; Set extruder 0 pressure advance
M572 D1 S0.05 ; Set extruder 1 pressure advance

When i got to the 1.00mm Z height, the Y axes started to jump, as if it was moving, braking, moving, braking. i killed the print as it was getting pretty load and i was afraid it was going to brake the printer.

Ok, Installed the 1.16 Alfa. The Ste-per motor noise is Still there. I did notes its only on coordinated moves. I can calibrate, move the table around and extrude and all is well. But i run a Print and the noise is there. Note - don't get me wrong this is not machanical, its motor drive control

guywinslow · 20 Oct 2016, 15:10

OK, This probably needs to be under the next release of the Firmware (dc42/Version 1.16 beta 2), but i could not find a Blog or forum for it. So hear is the info:

Ste-per motor noise is down to a Dull rorre (Sounds like a Skipping Hart beet). Its still coming out of extrude motor when i listen to it through a Sc-row driver handle.
Temperature control, the best i can do with Auto-tune is the hot end doing +- 0.3. it is holding that. at lest for the short print times i have been testing.

Going to let this test print finish to see if it finushes.

you have

M350 X16 Y16 Z16 E16:16 I01 ; Set microstepping mode

Should it not be

M350 X16 Y16 Z16 E16:16 I1 ; Set microstepping mode

or

M350 X16 Y16 Z16 E16:16 I0 ; Set microstepping mode

Depending on whether or not you are using interpolation or not?

Also your X and Y axis steps per millimetre are the same but your motor currents are different? are you using different motors?

guywinslow · 22 Oct 2016, 01:36

Same motors, one is the Y axes, heavy mechanism, it gets slope if there the same. will fix the M350 command. I uploaded the Firmware (dc42/Version 1.16 beta 3). noisy in the steeper motors is gone.

Was ruining another test print. 4mm x 4mm 75mm square. The over extruding started at about 3mm. Looks like its over extruding, then under extruding. Then go's back to normal for 60mm, then it dos it age-an.

That sounds to me like either a problem with your extuder drive, or inconsistent filament diameter.

guywinslow · 22 Oct 2016, 23:07

The filament would have to have a difference of .75mm to do this.

I went from:
M350 X16 Y16 Z16 E16:16 I1 ; Set microstepping mode, interpolation mode On
to
M350 X16 Y16 Z16 E16:16 I0 ; Set microstepping mode, interpolation mode Off

Second test print cam out OK. looks like its interpolation. Docs on Stepper state it needs a Good Clock pulse. Probably is noise or not up to snuf, it also explanes why its a repeting intervall. Adding to mush plastick then not enuff. All leave interpolation mode switched off

guywinslow · 13 Nov 2016, 22:21

Figured it out, Extruder issues:

M350 X0 Y0 Z0 E0:0 I0 ; Set microstepping mode

looks like my Stepper motors wont do microstepping mode. If i understand the command right. Symptoms noise steppers, Pore Speed control (Extruder). Switching to latest FW
