Had a crash. cleaned it out, went to do the limit reset, and parking position setting etc., but the machine goes directly to 'cleaning', drops the caps and sits that way beeping. I tried rebooting numerous times, tried holding the three arrows and booting, I manually raised the caps and then rebooted, and tried anything I could think of, but every time I power it up, it goes right to cleaning but sits and beeps. This began with the error number for limit resetting, but I can't get it to react, it just goes to cleaning again and again, without being prompted. Any Ideas what might be hanging it up?
