Changing print tempter for first few layers
Hi,
I just recently started printing on my pusa mk3s but I can't get some prints to print. I have tried to use a glue stick but that dose not work so i want to try adjusting the temp the first few layers are printed. how do I do this?
This my be a stupid question but I am still a noob.
can't get some prints to print
What do you mean? Not sticking to the steel sheet? In which case, it's either dirt on the sheet (clean with hot water and dishwashing soap, then use 91+ % IPA to clean between prints, never touch surface of the sheet with your hands), and/or wrong first layer calibration/Live Z. My money is on the latter. Use this https://forum.prusa3d.com/forum/original-prusa-i3-mk3s-mk3-assembly-and-first-prints-troubleshooting/life-adjust-z-my-way/ instead of the built-in method. I would start there before playing with temperatures.
If you meant anything other than not sticking, please provide more detail.

Most of my prints don't stick to the steal sheet and I have already tried to clean the steal sheet.
Clean it again with dishwashing soap (Dawn/Fairy) and plenty of HOT water. Make sure you get rid of all the glue then dry it with a fresh paper towel and DON'T TOUCH the printing surface.
Show us a picture of your first layer calibration.
Cheerio,
Here is a pic of the first layer calibration.
that looks as if Live Z is not set properly, the nozzle looks too high....

RE: Changing print tempter for first few layers
As i said in my previous response, my money was on bad first layer calibration, and your picture confirms it. You have to go a lot lower. I use the built in method in steps of 100 (0,-100,-200, etc) to get the zig zag pattern to have straight lines and right angles, then switch to the Live Z My Way method Joan and I have linked to to fine tune it. Try this and you'll be on your way quickly!
