I have had my Taz 6 for about 3 years and it has been running well. Recently,i noticed that it seemed to be loosing the z offset, almost smearing the first layer. I reset the z offset and ran a print and all seemed well. I went to run the print again after making an adjustment to the z-offset again and I received an error. The printer ran through the normal startup, homed x and y, then heated to 170 and moved tot he z axis switch, and ran a cleaning function but at 1/2 inch above the cleaning pad. I shut off the printer and restarted after about thirty seconds.
I started the cycle, the printer ran through the x/y home and then the z axis moved to about a half an inch of the z-axis switch and then reversed direction and flashed an error.
Any ideas on how to correct this? I am currently using S3D for a slicer for the Taz 6.
As an addition, for the past 6 months or so I have had to turn the Taz off after each print or it would start a new process about half an inch above the cleaning pad (would give a cleaning failed error).
