The problem was indeed Cura!!!
After trying with Simplify3D the speed was fast as usual and there were no stops.
Only thing that does not work is the part cooling fan. I don't know why this does not work as it is connected, activated in the reprap firmware and activated in Simplify3D...
My guess is that the port is not configured correctly in reprap but where can I specify which port to use for the fan?

Thanks oliof, I will try it with the gcode from Simplify3D first to make sure it's not a slicer problem but a problem with the firmware on the Duet...
I'll let you know if it worked out.

I also have the Bondtech extruder but currently the stock is installed. But it seems to extrude fine with these values.
Hmm no, I only tried Cura so far. I don't have coast / wipe enabled. I use the stock profile from Creawesome for the Ender 5.

Thanks for the tips but even after setting the speeds and accelerations that high the printer is as slow as before and it stops between every move. The problem must be something else... Probably the wrong steps/mm?

Hi JamesM

As the homing procedure and the moves work at a decent speed when executed manually using the web interface, I don't think wrong speed settings could be the cause. It only slows extremely down when trying to print something real.
What I will do is to check the "minimal layer time" settings in Cura as I think that could probably be the cause for the stop and wait time?

I am trying to set up the Duet Maestro with my Ender 5.
Starting with the configuration of mindoftea from this topic I was able to get the online tools working.
Homing, heating and extruding works as expected when executed from the online access tool.

Now when I try to print a file (test cube) I have several problems:

• Homing Z: Z homing is really slow, it takes several minutes to home the Z axis. After the 1st homing, when the Z axis goes down, the print already starts before the 2nd Z homing is done.

• Speed: The print speed is extremely slow compared to the stock mainboard. Still using the same Cura profile (only thing changed was Marlin->Repetier in the settings)

• Stops: After each print move, the print head stops for about 15 seconds, plastic dripping down during that time. Print times are expected to be 12 hours instead of 30 minutes for the little test cube.

What's going wrong here?

• Ender 5 all stock

• Duet Maestro, Firmware 2.03

• Reprap config from mindoftea

Thanks a ton for your help!!!

Hello, I have got massive problems with my hypercube using Duet wifi.
First of all, it's for sure my fault, not Duet3D's but I don't know how to fix these problems myself.

Build:

• 300x300x500 mm, for testing reasons only 200x200x200 mm are enabled.

• Mainboard: Duet3D wifi

• Material: 1.75 mm PLA at 200 degrees

• Extruder: Bowden (60cm), E3D clone with Nema17

• Circuits: 24 V for the electronics, 12 V for the fans

• Heatbed: 500 W regulated by mosfet

• Frame: 3030 Aluminium extrusion

• Printing platform: Selfmade, from bottom to top: Heatbed, 5mm aluminium plate, carbon fiber plate 2 mm, bluetape

• Bed-Probe: IR Sensor by DC42

My problems are:

• Bowden extruder: As soon as a print is started (after the first layer), the PLA seems to be stuck in the hotend. While pushing filament through the disconnected PTFE-Tube or through the heated nozzle with no print started, it works flawlessly. This problem leads to a massive underextrusion while printing but only occurs after the first (few) layer(s).
• Height of the nozzle: Even tough I'm using the DC42 IR probe, printing the first layer is not smooth. I have to adjust the Z-height by Z-Baby-Stepping often while printing...
• Speed: The printing head does not accelerate smooth. At the start of a movement it's very very slow which leads to an overextrusion while executing small movements. (if there's enough PLA extruded...)
• Extruder-motor: There are often squeezing noises coming from the gear while printing (at these moments when it seems that the hotend is clogged while printing). But as soon as the PTFE-Tube is removed from the hotend everything works just fine... The length of the extruded PLA through the disconnected PTFE-Tube was also measured and is correctly as expected.

I hope that you have some ideas what could technically be causing these problems. Because my knowledge ends here and I can't fix it myself. I don't know if I set up the Duet, the IR probe or simplify3d wrong or all of them..? Also bed probing is slow. (or at least the movements of the print head including the z-axis movement). How could this be accelerated?

Thanks for anyone reading this and trying to help me
