Duet WiFi with RRF 3.1.1 Ignoring Speed and Displacement Limits
-
Hello,
I am using a Duet WiFi with RRF 3.1.1 installed. I set up the maximum speed for the Z axis to be 10000mm/min; however, the motor does not go past 1500mm/min (I did a manual sweep of the speeds and increased the instant speed changes, accelerations, etc). Also, both minimum and maximum limits for my Y and Z axes are ignored by the Duet.
Any ideas about how to solve/troubleshoot both problems? They seem related in that the Duet is ignoring both commands. I also swapped motors, and it still behaved the same.
Might it be the DWC?
Thanks in advance!

Hi,
Well the last line of the config file you posted contains:
M564 S0 H0
That command tells the firmware to ignore min/max settings and to allow moving un-homed axes.
You also have another of the same command:
M564 H0:1
with an unusual parameter which I don't think is valid.
You have two sets of M570 commands.
Your M350 command is missing the I parameter.
You have M569 commands with a T parameter which is usually used with external stepper drivers. Are you using external stepper drivers?
You have endstops configured for X and U axes that you have not configured.
Try running M98 P"config.g" from the DWC console and see if there are errors or warnings reported.

Yes. Thank you for the quick reply! I'll try the recommendations.

@fcwilt I suppressed the commands you recommended. M350 doesn't need the I parameter. Either with it or without it, the Z axis motor does not go past 1500mm/min. Any other ideas?

@dieguito What kind of machine is this? What kind of Z axis do you have that is expected to move so fast?

M92 X3200 Y200 Z400It’s the step pulse width and step pulse interval (the first two parameters of T) in the M569 line that is limiting your Z speed. Each step takes 50+50 microseconds, and there’s 400 steps per mm (assuming your external driver steps per revolution is set correctly; the microstepping set in config.g is not used on external drivers), so maximum number of steps per second is 1,000,000 / 100 = 10,000 then divide by 400 = 25mm/s, x60 = 1500mm/min.
What external stepper drivers are you using? The timing is very long. Most drivers work with 5 microsecond signals something like T5:5:10:10.
