First layer is going to drive me crazy
I’m dialing in my Vcore 4 500 and I’m having so much trouble with the first layer. These are the steps I’ve been taking.
1. Start print and let nozzle heat soak for 300 seconds via gcode macro
2. Heat bed soaks for 1200 seconds via gcode macro
3. Z calibration and adaptive bed mesh
4. Print blob and begin printing first layer test.
5. Baby step Z offset until good layer. Run the “SAVE_Z_OFFSET” command in the console.
6. Wait for print to finish, then save to config and reset.
Then I start the next print which should theoretically have a perfect first layer without having to baby step right?! Nope, I have to adjust it every single time after the previous print. My z offset is changing I know because I don’t have to adjust as much every time as I did the first time, but why is it so drastically different every time? I’m having to +/- .03 every print.
I do have automated beacon scan compensation on, and even that isn’t helping. Am I doing something wrong? There must be something that I’m missing.

Can’t figure out how to enable nozzle wipers
Just finished building my v4 500 Hybrid (No hybrid belts installed yet) and I can’t figure out how to enable the nozzle wipers. I’ve been trying to dial in my first layer but I figured the nozzle wipers would have been used before or after printing and they aren’t for some reason. I added the macro in the printer.cfg file to enable it, but it still won’t use the wiper at any point during a print. Any ideas?
