Hi all,
I have a Tevo Tornado printer that worked well for 2 years. It was well maintained and everything was moving fine until 2 days ago.
Since then, it will print the first layer fine, then all the next layers will be printed inside the first one.
I can move the z axis from menu or from computer / slicer software slow and fast without any problem.
Also, during prints, when the command G1 Z1.3 F13800 and then G1 Z0.3 F13800 is sent, it works.
Only the command G1 Z0.5 F13800 to get to the next layer, seems to be ignored (and G1 Z0.7 F13800 and so on..).
I made no changes to the printer before.
After the problem started I did upgrade firmware from Marlin 1.1 to 1.1.9, then changed the drivers from stock to TMC2208, cleaned and greased Z axis.
If anyone have any clue what the problem is here, please tell me.
Thank you.
I must mention that I have already read this post [
