Hey
I think I'll try it with different timing.
I use the suggested nema 17 from stepperonline. Can you provide me your M569 T ?
I'm a bit frustrated

@gruna-studio I am using the default step timing (i.e. no T parameters in M569)

@dc42 or @T3P3Tony has stall detection been implemented on these boards? Thinking of getting rid of the end stops if possible

[dc42]

@samlogan87 stall detection should work in open loop mode, however RRF cannot yet use stall homing for motors connected to expansion boards.

[samlogan87]

@dc42 bugger. Thanks for that. Any idea when it might be implemented

[dc42]

@samlogan87 we're planning to implement it in RRF 3.5.

Note, stall homing is less accurate than homing using a switch; so not recommended if you want to support resume-after-power-fail.

Ok thanks a lot

I have constant layer shift on X axis. Can't solve it since days and several more boards are on the way.
Open a thread was not helping because nobody answered. Haha

Please help me

@gruna-studio I saw you deleted the thread, I was not sure why. Do you want to restore that thread so we can discuss the issue there? If you like I can restore the thread for you.

@t3p3tony

I have already trying a lot of things, so that this thread wasn't actual anymore.

Then I made a new one which is still online but after two days I could delete that, too.
It's also not up to date anymore.

I'm Sorry

So I'll change the boards and motors later on and will make a new thread.
Did you use 48 volt?
I "saw" a shift. The motor was less noisy and slower then normal for a short second. Like you shift in a to low gear in a car.
Thanks for you reply
I just ordered 4 more 1HCL - I'm very optimistic

Thanks
Richard

@gruna-studio please do repost with an uptodate setup.

I used 24V on my printer thus far.

@t3p3tony Thanks, snagged some up at Compass! Excited to try them!

[samlogan87]

Finally got the printer back up and running after rebuilding most of the mechanism. Still need to square it up as I think some of the noise is rail misalignment. That’s 1000mm/s at 30000mm/s acceleration using 48v to drive the boards

Nice
