HI ,
I am hoping I can get some help here. I changed my hot end to a Micro-Swiss for my Duplicator I3 Plus, prior to this everything was printing great and Cura was doing a great job. However at exactly the same time as changing my hotend, I loaded Cura and it had the update of 2.6.1. So I updated my software and it had a problem installing. So I totally uninstalled the previous version of Cura including all the files in teh Appdata folder and installed the new one. I eventually got it installed by installing it onto my second hard drive. I then gcoded something to test my hotend. The results were terrible. The models were coming out with massive structural problems, very weak and squishy.
As I had changed two things I then had to see which was causing me the problems. I initially thought it was my hotend and tested various temperatures etc and changed my PLA even though the previous one was working great. I was still getting the same results. I then change my hot end back to the original brass one. But the results were the same. So I loaded a benchy which had been coded in simplyfy3d and it came out great, (see picture). I loaded the STL into Cura and rather than use my previous default setting, I used one of the predefined ones to make sure it wasn't a setting I had changed. However the results were the same as you can see in the pictures.
I am at a loss now and don't know what to do. I don't want to buy the Simplyfy3D software as I can't afford it and Cura was working great for my needs previously. I must have done something but can't think what. Any help would be much appreciated as my initial enjoyment of 3d printing is wearing off as I am spending all my time trying to get this to work rather than design and print things.
I have tried reducing print speed, infill speed, changing temperatures etc.
