Moved to the LPC port forum since that may be relevant.

Can you also send M98 P"config.g" and post the results?

Also your homedelta.g?

Thanks. I'm afraid that's the extent of my delta knowledge and I know even less about the LPC port.

A video may help and the results of M122 never hurt.

Is RC2 the latest for the LPC port, or can you update to 3.2 final?

yes, i can

Phaedrux

From your video is seems like it's triggering the probe, but then skipping steps on one arm when it tries to return to the dive height causing it to lurch.

Are you sure there's no slipping grub screw or something like that?

There should be no differences between the LPC port and the normal version in terms of kinematics etc that I'm aware of. There are some other restrictions but that's mainly due to memory.

You can upgrade to 3.2 final from here https://github.com/gloomyandy/RepRapFirmware/releases/tag/v3.2_1

it happens only with delta calibration and mesh compensation, with normal use it is not observed

RepRapFirmware 3.2 does not solve the problem(((

Pardon my ignorance on the LPC port, but perhaps you can try using x16 microstepping to get a baseline?

I notice in your M122 there are a lot of hiccups which can mean skipped steps, so reducing the microstepping could help

The printer behaves the same way only with delta calibration and mesh compensation, no problems with printing and moving, I do not think the problem is microstepping but I can try

jay_s_uk

@Orang_ yea, I really wouldn't run anything higher than x16 on an LPC
