Can I skip the initial automatic calibration?

[ET3D]

I just got my Snapmaker 2 and ran into the known problem of the 3D print head digging into the print bed. I made sure the unit is assembled correctly (yeah, had the platform upside down), moved the probe sensor, updated firmware to 1.10.0, and did the M502-M500-G28 combo from a laptop.

Nothing helped, and because it’s the initial setup process, I have no idea how to move forward.I understand that there’s a manual calibration option, but I have no idea how to get to it when I’m forced to do automatic calibration.

Any ideas?

A350 stuck on calibration after factory reset

I received my A350 a week or so ago, and I have had it working and printed a half dozen small items. I tried to recalibrate it today, and it kept failing on the first point, pushing the print head way down until the motor skipped, and then aborted and jumped to the final z-axis step. I could not save at this point after I did the manual z setting. I have previously lowered the sensor to 1mm (credit card) height as I saw on the forums. I can also verify that I see the red light come on as the…

Bed calibration crashes during initialization II

Thank you all for your ideas! I mounted the CNC head to overcome the printer menu and then could update from 1.5.x firmware. But the issue with the bad response of the Y-motors stayed as before. Using the CNC positioning controls I tested the motor drives and found an issue in the Y-line: controls worked inverse ??? At the end I found a very curious solution I can’t understand but it works: I interchanged the Y and Z controller cables at BOTH ends and now the motors move correctly and also …

Manual Calibration

Sorry for the inconvenience. Here is a way to skip the users guide and turn off the auto calibration. Use the laser engraving module or CNC carving module and complete the uers guide. I think the default firmware is V1.7, and you can do as follows to turn off the users guide of 3D printing module. I will PM you the method. As for the probe sensor, you can check if it lights up when the module is close to the print sheet.

If you just want to skip the initial setup of 3d printing, switch the tool head to laser.
Then is it possible to update the firmware.
Hope this helps!

Thanks. What this highlighted for me was that I didn’t check the sensor light. It indeed doesn’t seem to come on, so I’m guessing that it’s faulty.

Thanks, but as I said I already updated the firmware. I noticed that it’s enough to not plug any print head, and then the screen goes to a file browser. I could then update the firmware from USB.

Hi ET3D, @Edwin can help you with a faulty unit. Sorry about the issue you have run into.

Hi @ET3D,

Please upgrade the firmware to version V1.8.0 or above, and you can turn off the fast calibration and auto-calibration.

I think you need to confirm if the probe sensor works as shown in the article.

Hi, @Edwin. As I said in my initial post, I’ve already updated to V1.10.0. That doesn’t allow getting past the initial calibration step.

Anyway, I see no red light, so I think that the probe sensor isn’t working.
