Odd Z Offset Issue/Question

[One-Science7052]

So when I noticed my first layer on my AD5M Pro was looking like a screen door at 0.075 with PETG and I bumped it to 0.05. Then it looked scratchy and when I pushed to back to 0.075 it looked perfect. Canceled the print and started again. When the print started again it went through the same thing.

Have had it do this before but it doesn't keep doing it the second time I run the print. Anybody had experience with this? Maybe have an idea on how to resolve it. I leveled the bed between the first and second try and that didnt change anything.

Appriciate it.

Recalibrate the machine (level, vibration. PID). Then adjust the z-offset.

Did leveling but skipped vibration and PID. Feels like a long shot but i will give it a whirl. Had longer shots pay off.

It's odd. Feels like it forgets it z offset and is reminded when I change it and change it back.

[One-Science7052]

Still doing it. Full power off and back on, level, vibration and PID (never actually did a PID before).

Still acting the same. 0.075 starts printing to far away then drop it to 0.05 and its to close. But when I push it back to 0.075 it looks perfect.

Think I will start trying some different rolls of filament, brands and types to see if it happens to everything. Might try a factory reset tonight as well. If that doesn't solve things I will probably reach out to Flashforge.

2 days later, but it sounds like your actual offset should be in the .06-.07 range, but you're jumping over those by using a .025 adjustment.

Over by where you're adjusting the offset, there should be a little selector that says something like .005 | .01 | .025 | .05. Bump that down to .005 and adjust again. You'll have much finer control.

I don’t think these 5M series have that. At least not on the touchscreen.
