Z hop in the new version ?

Sat Jun 18, 2016 1:51 pm

Where can I set Z Hop ?

I have a 2 process print , saved as 2 files but when I start the second process the printer extruder crashes into the parts already printed when the second process starts.

I want to add Z hop so it lowers the bed before it starts printing the second section.

It's in the same place it has always been. Extruders tab, labeled "retraction vertical lift"

That drops it between every layer. I really want it to drop at the start of process 2 to clear whats been printed by process 1

not between every layer. before every travel move so it should generally drop between process settings. not sure why your nozzle is hitting the parts. every print i do is usually a multi process and i have never had the nozzle crash into a part.

if for example I'm doing a few towers. 3cm tall. Process 1 prints to 2cm. Then I change filament and run process 2 as the extruder moves to the start point the bed doesn't drop fast enough and the extruder hits the 2cm towers.

you could make changes to end script in process 1 and possibly the start script in process 2

Almost all my parts are just like that with either 4 or 6 pillars a couple inches tall. Ive printed a couple thousand of these piece over the past 2 years and never knocked over a pillar when it switches processes. Is it possible you have your z movement speed set really low?
