@dc42 Thank you very much!
I have another question: How does the M597 command work to avoid collisions with two independent gantries with the new multiple motion systems feature of reprap firmware? I mean, if I set the "safe" distance of the gantries to 20mm, what happens when they reach that distance? Does one of them stop or slow down?
Hi there!
I am building a large 3D printer for my master's thesis and am having difficulty finding an unshielded twisted pair cable with a 120 ohm characteristic impedance for long cables. Is there a problem with using shielded twisted pair cables, which are more readily available? The Duet documentation recommends using unshielded cables for long distances, but I am unsure of the reason.
Additionally, I am using 10 motors with 10 expansion boards (one board per motor) and was wondering if I can connect all of these boards in series using a CAN bus cable with four wires (two for the RJ11 connector and two for power supply). This would simplify my cable management, even if I use a separate cable for power supply and the CAN bus, but still connect them in series.
Best regards,

Hi guys,
I'm building a CNC machine with a 400W Spindle (48V) that comes with a Mach 3 DC Speed controler that receives a pwm signal with a level of 3.5 - 12 V VPP. How can I setup this spindle with this controller?
I was thinking about using a pwm fan output from Duet but the output is 0-5V. Since I'm using a 24V power supply for the duet, can i use the fan output as VIN and add a step-down (24V to 12V) to connect to the spindle?
