This is my first post in the forum, and I tried my best to research this before having to ask the community, but I just this morning started having a bizarre problem with my machine.
Everything has been behaving itself up until today, when I tried to run a print and it started at layer 958 of 960 and it literally just pointed the laser in the front left corner of the vat and sat there. I shut the machine off, started back up, and after some standard maintenance tried the file again. This time it was on Layer 1 of 0 Total layers, and the PM motor simply lowered and raised the vat over and over again without pausing.
I’ve fully formatted the SD Card (using the included 16GB Kingston card) with the recommended tool and have tried different gcode (all from Asura 2.21/2.22)
I opened up the machine and took a look at the SD card reader pins and they all look pretty clean - no breaks that I can see, though I’m going to hand it off to an electrical engineer I work with for a closer look later today.
Based on the symptoms, does it look like it could be the card reader? Any other theories out there?
Also, I’ve been running this machine for roughly 5 weeks now and the knowledge of this community has been very helpful, so thanks in advance! I work as a technical specialist at an MRI research laboratory, and this machine is a crucial part of my tool set, any suggestions would be greatly appreciated!
