How do you set Z offset for PETG?
The trick to printing PETG is in your slicer set Z offset to 0.2mm and turn first layer speed and acceleration well down. I currently use 15mm/s speed and 300mm/s2 acceleration. The large Z offset is to make sure the nozzle does not tough the extruded filament as PETG is very sticky.
How can I improve my PETG bed adhesion?
Alternatively, if the filament isn’t properly sticking to the bed, it may be too cold. Naturally, this can also happen if you’re printing without a heated bed. The best way to solve this problem would be to apply some sort of adhesive to the surface, such as a glue stick or blue painter’s tape.
What is a good layer height for PETG?
For PETG I like a first layer height of 0.28mm which seems to help with the build-up issue PETG is known for. There are a lot of users that swear you need to “squish” your first layer with a layer height of less than 0.20mm.
How do you get PETG to stick to glass?
Use Painters Tape on Top of Glass Otherwise, the tape will start sticking to itself on its roll. If you are going to be building PETG prints on glass, you must remove this release with an organic solvent so as to obtain good adhesion. Many people utilize Isopropyl (rubbing) alcohol for this purpose.
When to use z offset on Slic3r printer?
Should it be desired to print away from the center, because of a scratch in the glass perhaps, then this option should be used. Z offset can be used to compensate for an incorrectly calibrated Z end-stop. If the nozzle stops slightly too far from the bed, then adding a negative value will offset all layers by that amount.
How big should a bed be for a Slic3r printer?
A Bed size of 200mmx200mm and a Print center of 100mmx100mm would sit the print in the middle. Should it be desired to print away from the center, because of a scratch in the glass perhaps, then this option should be used.
When to run custom G code in Slic3r?
Start, End and Layer Change G-Codes. Custom G-code commands can be run before a print starts and after a print finishes. Placeholders can be inserted in the G-code commands 1. For example [next_extruder] would return the index of the next extruder.
Can you use PETG to print PLA parts?
Having printed exclusively in PLA for the past year, I’m now looking at trying out PETG in order to print a set of spare parts for my new Prusa i3 mk3. I have bought a roll of PETG from Rigid.ink and their recommendation is to leave an extra 0.2mm gap between the nozzle and bed.
