First Power On - Calibration Error - Smashes Into Gantry

Got everything assembled and followed all instructions to the letter.

1st Power On: powered up → selected language → connected to wifi → selected calibration → Z axis has slight movement then stops → X axis hits right of gantry and keeps smashing against it → Y axis hits front of gantry and keeps smashing against it → I panic, finally remember where the switch is, and turn everything off.

2nd Calibration Attempt: I powered it back up and tried again hoping it was a fluke, same issue, but this time I was ready and had my finger on the off switch.

3rd Calibration Attempt: While powered off, I moved the print head to the back left and ensured it made contact with the limit switches. Powered on machine and skipped calibration. Connected to machine via Orca Slicer. Verified X and Y end stops reported correctly when print head was both making contact and not making contact. Powered cycled → updated firmware → still beating itself repeatedly against the gantry → powered off → start questioning life decisions that brought me to this point.

I double and triple checked my assembly. Searched for answers among other forms. Found one saying to change the settings for sensitivity for driver_sgthrs in Print.cfg ( Print head hits the gantry | Sovol 3D Printer Wiki ) Looks like the SV08MAX has different drivers than the SV08, so this is not applicable. Instead it has a homing_override gcode section.

I am at a loss. I plead to you kind 3D printer gearheads to help me out. I am new to 3D printing. Expanding out from laser engraving and woodworking and such.

Hi,

Since you printer is new and under warranty, email at info@sovol3d.com with your order number, an explanation and pics.

They’ll be back to you within a week.

This is the 2nd one of these posted over the weekend.
We need some insight.

I emailed Sovol as @mich0111 suggested. They got back to me within like an hour. Super effective.

Turns out, the Y Motor connector (see attached image from Sovol) can be installed upside down. Despite the connector itself having shaped connector pin insets.

There is no mention of this potential in any of the documentation that came with the equipment.

@sovol3d Please add a sticker or something on your future shipments for the Y Motor connector describing this potential installation problem. And also, thanks to you and/or your comrades for the quick response to my email.

And also, thanks form members for the assistance.
