So I recently upgraded my SO3 to XXL. Finished putting the thing together and I am stuck at the upgrading software process. I downloaded the CarbideUpdater, and I am stuck at the second process. Whenever I run the updater, it would tell me to hold down the Z axis limit switch until the updating is complete, but a few seconds after I hit OK while holding down the switch, it would give me an error that says “avrdude error, please make sure that you hold down the Z axis switch until the upgrading process is complete” or something to that effect. I even taped down the switch just to make sure, but still the same issue.
Any help would be greatly appreciated!
P.S
I think I am using the original controller board. Should I still upgrade the software? Or just leave it be?
So apparently, I don’t have the “prog” button on my board, there’s only one button and it says its for reset. I think the board that I have is the original/first board controller for SO3.
Do I need any HEX files for it? Sorry for all these questions, im not huge when it comes to these kinds of stuff. The title says reflashing to GRBL 0.9.
I just had the same problem. I found I had a intermittent problem with my z limit switch. I had to unplug the x from the board, also unplug the z from the board and connect x to the z position on the board. Then hold down the x switch and it updated. Essentially tricking the updates, using the x in place z. I still have the problem with the z switch. Boy the switches feel extremely cheap and unreliable.
