Duet V3 6hc stepper problems

[3DGarage]

Hello, so I have installed and compiled firmware for my modix printer on Duet V3 6hc, but cant get it running propertly. Main problem is that while homing x axis y axis moves to, same happens if I try to home y. Checked the firmware with few engineers everything seems to be right. Any Ideas what could be causing this anomaly that both y and x steppers get signal from the same command?

Modix printer on Duet V3 6hc, [ ]. Main problem is that while homing x axis y axis moves to, same happens if I try to home y.

According to the Modix website, all models are equipped with Duet 2 controllers. Is this info outdated, or did you replace the controller with a 6HC on your own?

If the 6HC was provided by Modix, they are the first address to ask for support.

To get assistance from this forum, please provide us with the config.g you’ve created. Use the </> symbol from the header of the thread's edit section to tag the text.

From what you describe, it looks like you didn’t tell the Duet controller about the kinematics of the printer: to my (severely limited) knowledge, all Modix' are CoreXY, so you should have this in your config:

M669 K1 ; switch to CoreXY mode

For details, refer to this documentation: Configuring RepRapFirmware for CoreXY Printer

Our old Modix duet 2 controller had a short and burned its drivers, so we have ordered a new controller Duet V3 6hc as I mentioned before. I'm attaching link to the drive to the whole firmware folder with all the files including home and config.g . Firmware zip folder its named new compiled firmware.zip. I also included videos of whats happening exactly. I would appreciate if you guys would be able to check what am I doing wrong.

@3DGarage OK. Here's your config.g replicated inline so that forum members can easily read and contribute:

I also included videos of whats happening exactly.

I am unable to locate any videos on your public drive.

@3DGarage For reference, here's a config.g (for Duet 2, RRF 3.4.5) published by Modix on GitHub. I'm not sure if it matches your printer, and it doesn't match your 6HC for sure.

A noticeable difference to your config is in the definition of the X endstop: according to Modix, it is positioned at the low end. In a first step, you need to verify this to match the printer's geometry.

Apart from being quite elaborated, you may want to incorporate at least some of the values Modix has set for Accel, steps/mm, speed changes, axis limits etc. in your own config.g.

EDIT: I was wrong with my assumption of the Modix being a CoreXY - please remove

M669 K1

from your config.
