If the distance between the nozzle and the platform is too large
or too small, please stop printing and adjust the platform until the
distance between the platform and the nozzle is appropriate. In
most cases, the printing failure is caused by the platform not
being adjusted properly. Therefore, please debug repeatedly as
required to ensure that the platform height has been adjusted to a
better level. And when printing the first layer, it's best to watch the
machine print and make sure the machine prints properly before
leaving.
