Quick question about the height adjustment process.

In the instructions on Clough42's website, it says to run G28 (autohome), then G29, and then move the nozzle to the center of the bed and adjust the height and enter any z offset adjustement.

When I have been adjusting the height I have been doing it from where the carriage is at the end of the G29 process. Would this be causing issues with inconsistent height problems?

I am seeing problems lots of issues (way more than I was having with my stock Hexagon hot end setup) with first layer height. Sometimes it is so close to the bed no plastic will extrude, other times the nozzle starts hitting on previously deposited plastic.

Any suggestions on what else might be affecting the height that I should be looking at?

Thanks,
Bill
