I need to G29 at least 3 times[BUG] #24

Open GonzNRoses opened 4 years ago

GonzNRoses commented 4 years ago

Hi, I recently have installed this firmware and a BLT but having some troubles

Describe the bug I am getting this error and don't know how to fix it. If I start a print right after turning on the printer, it starts too far from the bed. The second time it get closer and, from the 3rd one, it is perfect, as it should be.

If I manually execute the auto level twice, and the gcode contains a g29 to perfomr the 3rd one, it print right, if I don't, it print too high.

To Reproduce Steps to reproduce the behavior:

  1. Start printer
  2. Start printing
  3. See error

Expected behavior A perfect first layer

Photos of the print / output of the terminal I don't think you need it, just a high hotend at first layer. If you do I can upload it.

Printer (please complete the following information):
