Nozzle scraping bed during beacon calibration
Look at the photo of the board on the next step - Step 19. Do I follow the text or the photo - if you're a nube (rube) like me you go with the photo. C'est la vie...

X stopped working when changing to Hybrid
Folks - for what it's worth I was able to rectify the independent motion x and y on my hybrid machine. Confusion in the build guide I defaulted to "SPI" mode for the drivers. Waiting for an answer here I decided to clean up some wiring and try out UART mode. The toolhead now moves independently in both the x and y direction, and perhaps more important to me homes to 200,200 and straps out the same off the board. Moving the head to 0,0 puts the toolhead in the front left corner of the bed. I hope the same works for you if you had your jumpers set up the same. SPI - 4 jumpers installed on the right two pins for every driver slot. UART - only the right two pins have a jumper on the second row from the top of each row of driver slots. Bon chance!

Nozzle scraping bed during beacon calibration
Mr./Ms. Pereira - I am somewhat pleased to inform you that this situation was directly attributable to a condition known as "short between the headsets". There is some confusion in Section 12 of the build guide whether to set the jumpers for "SPI" or "UART" mode - the board photos in the guide show both. I reversed my initial config from SPI to UART and two things occurred: 1) x and y move independently; and 2) the toolhead homes to 200, 200 and straps out to the same off the bed. Sending the head to 0,0 puts the toolhead in the front left corner as it should be.

X stopped working when changing to Hybrid
No worries. I'm groping in the dark as well. I'm not sure if it's of any relevance, but are your wiring layouts the same on for the JST connectors going to the board. I've different variations depending on which motor it's coming from. Still trying to get somewhere positive with this: https://discordapp.com/channels/582187371529764864/1340069988714676366

X stopped working when changing to Hybrid
Did you make it past the calibrations in the commissioning guide? My toolhead went off the right side of the bed - that's what started all of this.

X stopped working when changing to Hybrid
I'm gonna tag along 'cause I've been dealing with this same issue for 3 days now. Y motion when homing x. Y position shows 200 after homing, and straps out the same. X position shows 200, but sits at 85. Checked it this morning - move x 50 and that translates to 25 when measured on the plate. I haven't tried unplugging the hybrid motors yet - just glad I'm not the only one....

So is there something else that would cause that stepper to halve it's distance that I can change?

I had that thought early on. The bags say 20T, but I guess I need to actually count.

Checked movement of the toolhead this morning. Issued a Mainsail command to move on the x axis by 50 mm - It moved 25. Still using the originally configured Klipper axial constraints. What would you think the best place to start troubleshooting? The motors are to be responding to direction correctly, so would you think this is a mis-applied software multiplyer, or more like a miswired stepper motor jumper?

If both are whole numbers how do you end up with a position to a tenth? Is it hitting the endstop and then gauging the distance based on turns of the pulley?

Nozzle scraping bed during beacon calibration
I've not made it out of the Commissioning guide yet. It went off the bed while calibrating. I've been manipulating the default (configurator) Klipper values for x and y and I think I'm getting close. I'd assumed that the x/y min and endstop values were standard for the printer you selected in the configurator. I've changed the values such that when I home x and y the positions are listed as 200, 200. When I enter 0 for a position for either I'm almost to where the toolhead gets to the front left corner of the bed per Klipper guidance.

Nozzle scraping bed during beacon calibration
Managed to complete the Z-tilt without scarring the bed. Is it normal for the scan to only encompass about a third of the bed? Toolhead is only traversing 1/3 of the bed, and I'm getting "missing clusters"
