If i just run a G1 X200 command i would expect the printer to move at maximum speed, but the printer does not move faster than 3000. I've looked through some GCode from Slic3R and that starts out by defining the speed within the first travel move. This means that the whole problem is more or less pointless.
Thank you very much for everyones help.

My M204 is default at 10000

My M566 values are set that low for now, just to be sure that i don't get any vibrations throughout the structure while printing. This is also why i'm running fairly low accelerations.

Yes i know. But the problem is that i cannot seem to set this limit in my config higher than 3000 mm/min.

@bearer I assume the problem comes when i try to use print speeds over this limit. Given the fact that slicers write the exact same Gcode as in the config file i will not be able to move my printer with more than 50mm/s, which is not fast.
I have yet to see a slicer that writes the feed rate for each axis behind the G1 move command.

Hi all

I have now run into a problem where my motors will not spin with a feed rate over 3000 mm/min, no matter how high a value i set in M203. The speed of the movement change up to 3000 mm/min from where it just stops. If i run a G1 command with a corresponding feed rate of F15000, then there is no problems, but i cannot hardcode it in the config file.

I there something i'm missing? My config file for the drives are as follows.

; Drives
M569 P0 S1 ; Physical drive 0 goes forwards
M569 P1 S1 ; Physical drive 1 goes forwards
M569 P2 S1 ; Physical drive 2 goes forwards
M569 P3 S1 ; Physical drive 3 goes forwards
M350 X16 Y16 Z16 E16 I1 ; Configure microstepping with interpolation
M92 X55.00 Y55.00 Z5050.00 E420.00 ; Set steps per mm
M566 X60.00 Y60.00 Z12.00 E120.00 ; Set maximum instantaneous speed changes (mm/min)
M203 X15000.00 Y15000.00 Z1000.00 E1200.00 ; Set maximum speeds (mm/min)
M201 X500.00 Y500.00 Z20.00 E250.00 ; Set accelerations (mm/s^2)
M906 X3000.00 Y3000.00 Z3000.00 E800.00 I30 ; Set motor currents (mA) and motor idle factor in per cent
M84 S30 ; Set idle timeout

I found a solution. The local website is not called DuetTest, but myprinter.local. I do not know why this changed, given that i changed the name of the printer and the website name did not follow along.
I cannot see anything else in my config file that could have changed this.

@T3P3Tony Exactly nothing. It doest nothing. It just says that there is no connection.

@T3P3Tony Im using Win10, latest update, and it worked previously, but only a couple of times. Since then i haven't gotten it to work.

But why does the DuetTest.local not work. I did the first couple of times?

Thank you to everyone that has answered. I am running a Duet 2 Wifi, and cannot seem to find a way for it to set a static IP, only the ethernet has that option as i believe.
I am running RepRap for Duet 2 Wifi V2.02.

Hi

I was wondering if anyone could tell me why my DuetTest.Local does not work when i can input the IP-Address from the board directly into my browser and get to the control screen of the Duet 2 Wifi.
Not that it is a big problem, but when the IP of the board changes i have to go through YAT to get the IP.

Thanks

@dc42 Everything is working now. It was the enable signal. Thank you very much for your help.

@dc42 I am currently only using M584 to set the X axis to port 5 to 9 to test all ports on the breakout board. I have currently not attached the Enable pins, given the same thought as you mentioned.

@dc42 I am using a FuyuMotion FMDT220A48NOM Stepper driver and a Nema 34 stepper motor.
I have connected the S+ to 5PU+, S- to 5PU-, D+ to 5DR+ and D- to DR-.

You can see the circuit diagram for their motion controller and the stepper controller below.

@whosrdaddy Yeah that makes sense in my head too. If i need to run stepper motors of the build in drivers then i would need extra voltage, but given that the stepper driver is hooked directly up to the wall, and the board only has to output a digital signal i do not know if i needs more voltage.

This might be a really stupid question. I have the board hooked up to my laptop now, and the stepper driver directly to the wall, but does the board need more power than what my laptop can provide to send the signal?

Hi Everyone

Thank you for the answers. This is the setup i am using at the moment. The printer is designed but not build at the moment.

Using the G0 Xnnn S2 code, the warning disappears as it should, but the stepper motor is not moving still. I have the driver hooked up the the breakout board on port E2, number 5. I then use the M584 X5 to set the x-direction to this port.
With this and the S2 addition to G0 i would expect the motor to start turning.

Hi

I am currently designing a large scale printer for which i'm using external drivers and the Duet 2 Wifi Board + Breakout Board. Currently i am testing to see how the board works and how the stepper drivers work, but i cannot get the motor to run. Every time i send a G0 command it returns with "G0/G1: Insufficient axes homed. The command M564 H0 S0 which should solve the problem does nothing.
I there something i'm missing, or is it simply impossible to test the stepper motor without having the rest of the printer hooked up?

Best regards
Andreas

Hi

I am currently designing a large scale printer which requires external stepper drivers. To run this i need to use the breakout board. The output pins on the breakout board are Step+,Step-,Dir+,Dir-,Enable+,Enable-.
The stepper drivers i have been able to find do not include input pins with these names. Most of them use Pulse+,Pulse-,Dir+,Dir-,Motor Free+,Motor Free-.
The direction signals must be the same, but is the following correct?

Pulse+,Pulse- = Step+,Step-
Motor Free+,Motor Free- = Enable+,Enable-

The stepper driver i am looking at is the FMDT220A48NOM , from FUYU motion.
