Z height? You mean layer height or distance between nozzle and build plate?

Yes I mean adjusting Tha gap between the nozzle and the build plate. So if you start a print and see that you need to adjust The gap you will be able to do it live without stopping the print and adjusting manually the bed height.

You mean input a Z offset during printing?

Vicky, I had questions about adding this too - I think another manufacturer did something where you can "thumbwheel" adjust the gap while printing the first layer -

I would find that very handy for those times I see its either too close and smashing out filament or too high and laying down a noodle while just starting a print - like during the skirt or brim printing -

I almost always print with a brim and use that for the same purpose - just to verify my gap is correct - and restart the print if it isn't - which doesn't take a long time, but if I could nudge the table up or down a few 0.01mm steps it would fix it.

I haven't asked for the adjustment because (unfortunately) it doesn't solve the problem - it only corrects for that print and your next print will start again at the incorrect gap...

Actually, yes. The best way to solve the problem originally is to adjust the distance between nozzle and build surface at origin height from hardware. We understand that adjusting the offset in software is easier and more time-saving to carry out. But basically it is due to hardware.

I have changed my bed to a 4-point spring-loaded setup with thumb-screws under the Z-table. If I need to make a small adjustment I can dial it up or down a touch without issue. I used this wave spring to minimize the z height change. I have it nearly fully compressed. https://www.mcmaster.com/#1561t15/=1cr3e0f
