@T3P3Tony, thanks a lot for your response.
Seems like an interesting solution to try.
Will surely put it to the test.

Dear all,
I need help in the following matter. I have a self-made 3D printer consisting of a moving bed (X, Y and Z motors), and instead of an ordinary printing nozzle, I have 3 syringe pumps (U,V, and W motors) -printing biological scaffolds-. I would like to: continuously extrude from the syringe pumps using ordinary command for U,V, and W (G1 U10 V10 F10; which is already optimally working), while the X,Y, and Z motors are moving to shape the scaffold. In summary, the union of ((U,V, and W)) is working perfectly. The union of ((X,Y, and Z)) is working perfectly. I just want that both unions work simultaneous way. (The use of G1 X Y Z U V W, all motors in the same command is avoidable); I was trying to use M596, but was not working as shown below -corrections to the code are most welcome-:

;Process1
M596 P1;
G91;
G1 U2 V2 F0.792;

;Process0
M596 P0;
G4 P100000;
G90;
G1 X100 Y100 Z0;
G91;
G1 X-60 Y0 Z0;
G3 X0 Y-10 Z0 I0 J-5;
G1 X50 Y0 Z0;
G2 X0 Y-10 Z0 I0 J-5;
G1 X-50 Y0 Z0;
...

Thanks in advance.
Best,

@Phaedrux, feedback: I put it to the test and it works ! thanks again !

@Phaedrux, Thank you so much for your on-point remark ! Best, Selman.

Hello,
Any assistance could be highly appreciated.
I have problems with accurately controlling the speed of the motors using DUET 3D.
Let me explain my case first: I am have a 3D bioprinter prototype. Instead of using ordinary printheads, I have self-made extrusion pumps. these pumps consists of a stepper motor that presses an ordinary syringe, which by its turn extrudes the material outside of it. What concerns me is that I have difficulty controlling the speed and the feedrate control of these motors. I have verified that the steps-per-millimetre is correctly calculated, and the theoretical and real displacement match. yet the motors are unable to execute the actions sometimes at the right speed. For example:
G1 U10 F5: executed in 20s. wrong
G1 U10 F10: executed in 20s. wrong
G1 U10 F20: executed in 20s. wrong
Above F50, correctly abiding by the feedrate rate. correct execution time.
Any thoughts on that?
Thanks in advance.

@droftarts Thanks a lot for the help ! Fore sure it was very helpful ! I was stuck in the situation where my PC (windows) could not detect the presence of the DUET, and so i used Type-C/Type-C cable, which turned out to be critically important. Many thanks once again !

Dear all,
I am new to the world of 3d printers and its instruments, so I may have beginner questions, but bear with me !
My laptop is not detecting the Duet 3D MB6HC, directly connected to my pc. For some reason, it seems to be unplugged. Earlier, it showed it, but all of a sudden it stopped. what could be the solution for that?
