@zapta your'e right I only want to reduce the chance of unintentional changes. In first place I would only secure the system files like Config.g, Home.g ...

@zapta yes I think so. But I haven't thought it all the way through yet. If you have some suggestion, I'll be very thankful.

Thanks for the answers. At the moment I will try the M551 comment, but for long therm application I try it to implement it by my own at the DWC.

Hello,

is there a way to secure the system files with a Pin or anything else in the DWC?

Implementation of Variables of GCode Meta Comments would be useful. Or is this function already implemented?

Ok so i did miss understand the concept of deselect tools.
Thank you very much for the help and quick reply.

Hello,

i detected a issue which wont deselect Tool0 manualy.
First off my configuration, i using:

• Board: Duet Ethernet 1.02 or later + DueX5

• Firmware: RepRapFirmware for Duet 2 WiFi/Ethernet 3.01-RC4 (2020-03-16b1)

Let's say Tool0 is already active and i want to deselct it i typed in the DWC "T-0" to deselct Tool0, nothing happens. If i press on the "Heater1" or "T0" sign, the Tool0 will deselct and set to Standby like it should happen. So i wonder is there a difference between T-0 and pressing Heater1 or T0 in the DWC?

Then i activated the Tool1 and typed in the DWC "T-1" the Tool1 will be deselected like it should. It seems that it only doesn't work for Tool0.

Does anybody have a explanation for this behavior?

@Philipp-R That config is exactly the same bar the steps/mm that I had on my V1 Nimble so the settings are valid for that as well but for a V1 I would have expected your Steps to be closer to 2700!

I use a special Extruder which need this 1900steps/mm

@Danal said in Motor don't turn at direction change:

Per a statement by DC42 several months back, Extruders only use accel and jerk when they reverse. They do not use these numbers when 'changing speed' in typical slicer output that has lots of short G1 commands with very small numbers of mm for the E movement.

Nonetheless, for purely debugging, you could try setting Jerk to 0 and accel really low. I don't expect that to change anything, but the "proof is in the pudding".

I already tried it and it doesn't work. It seems to me that the inertia at some point, in my case arround 14rev/sec, takes over the stepper torque. Maybe a more powerful Stepper would solve the problem. Becaus i am already at the limit of the 1.6A per phase.

Yah, I'm not surprised. It was a little bit of a "shot in the dark", just something easy to try.

Do you happen to have the model number, or the specs, on the motor that is on the extruder? And what voltage do you run, 12 or 24?

i currently use a E3D Stepper: Comapct but Powerful version with 48mm bodylength. I also changed the motor to the smaller version with 40mm Body. I ran my motors at 24V.

@Dougal1957 said in Motor don't turn at direction change:

Just to add a bit of clarity here the nimble he is using I am guessing from the e-steps is a V2 which has a gear reduction of 20:1 so it will be a 1.8 degree motor.

Looking at your config I think you have the settings for the nimble widely of what is needed

These are my settings on a V2 for you to compare

M92 X200 Y200 Z200 E1667 ; Set steps per mm
M350 X16 Y16 Z16 E16 I1 ; Configure microstepping with interpolation
M566 X900 Y900 Z900 E40 ; Set maximum instantaneous speed changes (mm/min)
M203 X18000 Y18000 Z18000 E2400 ; Set maximum speeds (mm/min)
M201 X1000 Y1000 Z1000 E120 ; Set accelerations (mm/s^2)
M906 X1000 Y1000 Z1000 E500 I30 ; Set motor currents (mA) and motor idle factor in per cent
M84 S30 ; Set idle timeout

As you can see my motor current, acceleration, max instant speed changes, max speed and jerk are all a lot lower than yours!

HTH

Thanks Doug,

i will try it tomorrow and reply to you if it worked. By the way i'm using a V1 Nimble (1:30).
