Ability to change movement/feedrate button increments, please

I work with a 8x8x6 meter concrete printer...... 100mm is not very long to move, and 6000mm/sec is just slow af....

@Kulitorum here.

I tried to use G2 and G3 but they are not interpolated very nice in current firmware and pausing during a G2 or G3 messes up and the printhead moves in random directions. I talked to dc42 about this, but I guess the current use of G2 and G3 is too low for him to spend time with it.

So I use very short lines of a max of 5 mm. With good jerk and acceleration parameters, that moves smoothly and allows me to pause a print at any time within 25mm, in regards to 4-5 commands being buffered in firmware.

Your slicer should keep an eye on overflow (crossing 360 degrees) and if needed "rewind" the rotation back to 0 to untangle your wires.

Now watching thread, if you need more help. Unfortunatly I can't share my code.

750w servo motor on the x-axis.

I hope to print at this speed, but I have set the expected speed at 300mm/sec. We'll see what the concrete pumps can do.

This is the printer:

@t3p3tony Yes, I did that already, so that you can pause the machine quickly if there's a minor issue. I'm cutting all moves into 5mm sections.

How did you get a Duet to be this noisy?

The design is wasting a lot of space on the XY plane, and not gaining much from it. And you move a lot of weight around for no real reason.

The couplers have to be 100% centered, and I doubt these are, as they are tightened from one side.

At least put the motors "outside" the moving area, so they "stick out" of the frame. This will increase your printable area around 10cm on both axes.

Lots of design issues IMHO

Once I receive the expansion boards, I will experiment with this. Any ETA?

@JoergS5 Thanks, looks good.

hehe, shame.

I print 1000mm/sec with vertices for every 5mm...

So can I amplify the signal every 40 meters? - Do expansion boards daisy chain?

I was hoping for 150m

Will everything work at 0.25Mbps?

What is the max cable length for the CAN-FD Bus?

Kulitorum

Thank you, that worked.

So I compiled DWC myself and uploaded it with upload file, and now I can't change page.

I only have access to the first page of DWC, and can't upload another version.

How do I recover from here?

I would like that too, if you deliver a printer to a customer there are certain functions that you don't want them to access.

Maybe add a warning message to the "!" in the top left corner?

You were right. Taking the voltage down to 26v fixed the problem. thanks.
