@C3DS thanks you for your support!!!

I bought my CR-6 SE printer in the fall and had a need to do some out-of-the-box printing straightaway. While it worked for the small footprint objects I was printing, the Z-axis homing and offset was inconsistent so I had to be careful about rechecking between every print. After searching about this phenomenon I came across this forum thread and it seemed to address what was by all accounts a firmware upgrade need. After studying the thread thoroughly I finally got around to doing the firmware upgrade. I have to thank all those who came before me working out the kinks in the "documentation" and process; as they say, "standing on the shoulders of giants". I used the 8 GB SD card (reformatted to 32K to 4K allocation size) that came with the printer to perform the main board firmware update. I managed to scrounge a 4 GB microSD card (also reformatted to 4K) for the display firmware update. Both worked the first time through the upgrade process. As indicated in a number of places, I do wish Creality would be more consistent in labeling the firmware package version information. Now the Z-axis homing and offset are consistent, at least as many times as I rechecked it from various random offsets. I also had to perform a Z-axis bed leveling to take out the skew across the bed. I found a video that indicated loosening one of the Z-axis pulley screws at the top and tweaking the lead screw will adjust the gross Z-axis offset across the center of the plate. The adjustment was a little tedious but doable and I got it very close by eye. It's a little off along the front and back edges of the plate, but now I hope the auto-leveling will have an easier time compensating for fine adjustments. Thanks for al the information and experience provided in this thread.

@Sonics99 said in How to switch to CURA 4.7: Thanks, I was wondering about this and if it was a smooth transition to go to 4.8. Were you just able to do an inplace upgrade? Not ncbob but I had some snags w/ Cura trying to migrate settings, so ended up clearing the Cura user data folder after installation and starting fresh. Have been using 4.8 beta since it dropped and results have been very good.

Has there been a fix for this? I've had 2 of these printers do the same thing. At the beginning of my prints it forces the nozzle into the bed causing the stepper motor to cog. Then, I have to shut off power. The printer cannot be used.

A question that has not been answered here still is this: is ABL on without an explicit M420 S1 command ? There's lots of warning in the marlin firmware documentation that a G28 disables auto-bed-leveling and you need to turn it back on afterwards.. i'm getting mixed messages about whether it is required in the preamble G-code for your slicer. Would appreciate advice here from either the community or @admin !
