@dc42 Thank you for your suggestions.

Indeed, the issue was caused by motor currents inducing some noise in the sensor cable.

I followed the procedure I described above and then simply sent an M18 command to disable the motor, and it worked fine. However, when I sent an M17 command to enable the motors again, the issue reoccurred.

I’ve since changed the wiring, and now everything works perfectly.

Thank you so much for your help!

@Philipp-R sure, I'll contact you via PM.

@dc42 This is true, but it was a long print and I want to define the pressure advance by feature without a few thousand human interactions. I ended up noting the layer height, stopping the program, doing a find/replace in a text editor, deleting all the lines up to the layer I left off on, and starting a new print. It would be useful if we could pause a program and edit the gcode that's yet to be printed.

This is what I was testing:

{REPLACE "; feature inner perimeter" "; feature inner perimeter\nM572 D0 S0"} {REPLACE "; feature outer perimeter" "; feature outer perimeter\nM572 D0 S0.85"} {REPLACE "; feature solid layer" "; feature solid layer\nM572 D0 S0.85"} {REPLACE "; feature infill" "; feature infill\nM572 D0 S0"} {REPLACE "; feature dense infill" "; feature dense infill\nM572 D0 S0"} {REPLACE "; feature gap fill" "; feature gap fill\nM572 D0 S0"} {REPLACE "; feature external single extrusion" "; feature external single extrusion\nM572 D0 S0.85"} {REPLACE "; feature skirt" "; feature skirt\nM572 D0 S0"}

@T3P3Tony thanks for your reply. I will test it like you mentioned and report the result in a few days.

So i tested it with this configration, and now it works like it should:

M584 X0.0 E0.3:0.4 ; set drive mapping linear axes M584 A0.1 B0.2 C0.5 S1 ; set drive mapping rotational axes M350 X16 A16 B16 C16 E16:16 I1 ; configure microstepping with interpolation M92 X36.2 A28.5 B28.5 C15.0 E400.00:400.00 ; set steps per mm M566 X500.00 A500.00 B500.00 C500.00 E1200.00:1200.00 ; set maximum instantaneous speed changes (mm/min) M203 X20000.00 A20000.00 B20000.00 C20000.00 E1200.00:1200.00 ; set maximum speeds (mm/min) M201 X2000.00 A2000.00 B2000.00 C2000.00 E2500.00:2500.00 ; set accelerations (mm/s^2) M906 X1000 A1000 B1000 C1000 E800:800 I30 ; set motor currents (mA) and motor idle factor in per cent M84 S30 ; Set idle timeout

My Gcode is "G91 G1 X500 A500 B500 C-500 F500" and the X-Axis moved 500mm in 1min.

@T3P3Tony Thank you very much for your help😁

How many tools do you actually have? It seems like you only have 1 tool configured, but you also have T-1 P0 in there. And you have 4 extruder motors defined.

What is this? M98 P"Actual Toolnumber.html"

@dc42 thank you for your help David it worked.

By the way i have found one thread about this topic: https://forum.duet3d.com/topic/18942/calculating-tool-offset-cnc/3?_=1604994474624

Yes at some point the heightmap must be loaded with G29 S1 (or created fresh with just G29). Usually this would be added to the slicer start gcode AFTER the z axis has been homed with the probe.

@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 ...

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

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

@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!

Doug

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

The only components I can think of on the Duet that have significant life limits are the SD card and the electrolytic capacitors. You can replace the SD card yourself with one rated for industrial use. The electrolytic capacitors we use are these high temperature, long life, automotive-qualified ones https://b2b-api.panasonic.eu/file_stream/pids/fileversion/3117, not cheap consumer-grade ones, and we use 50V rated ones even though the maximum expected voltage is only 30V. So I don't think there is anything about the Duet that doesn't qualify it for industrial use.

Duets are used in print farms, which surely qualify as industrial use.

I would think using M42 instead of M106, effectively not using the pin as a fan should sort you out?

@philipp-r Glad that's fixed.

@philipp-r said in Mesh Bed Compensation, doesn't change Z-Height during Print:

But don't you think it's a little suspicious that the values of the Bed probe heights are all zero?

No, those probe heights have NOTHING TO DO with mesh bed compensation. After you run auto calibration, they will be the height errors of the first 5 probed points.

And also when i start a print it, the nozzle height is clearly not constant above the Brinting bed. More than 0.1mm. So i expacted the Mesh bed compensation to compensate this offset.

If your probe is offset from the nozzle, then that's almost certainly caused by the effector tilt varying with XY position. See https://duet3d.dozuki.com/Wiki/Calibrating_a_delta_printer.

@philipp-r 👍 Glad you got it sorted out.

@5AxisSlicer said in 5-axis kinematic firmware:

@deckingman How about this then: https://5-axis-slicer.com/

This in reply to a post a made in Feb 2019 - 4 years ago............?? If you want to advertise the fact that you've developed a 5 axis slicer, then I suggest starting a new post with that as the title would attract more interest.

Ok thanks for your help!
i will try it, and will report if it worked.

Thats great that you are planning to work with loops.
Will see forward for that.
