@cope413 I recently started experimenting with PrusaSlicer and I noticed that my Ender 3 is printing a lot faster. I had shown these pictures to a couple of folks that I have purchased 3D printed products from and they basically said the same thing you did. I just looked at the settings in PrusaSlicer and first layer speed is set at 30mm/s and the first layer height is 0.35mm. For reference, the same settings in M/C are 20mm/s and .20mm respectively. I wanted to try PrusaSlicer because James Fewster, who prints commercially, had high praise for it. One of the things I noticed is that an STL file exported by M/C and then imported into PrusaSlicer reports the there are various errors that need to be fixed (which it does). I re-slice and export the file as Gcode, then open that Gcode in Matter Control and print it (a bit involved I admit). It seemed that, overall, I was getting better prints, except when there was a large first layer surface area as in this item. Based on your suggestions I think I will go back to this single layer test print with the slower and lower settings and see if it makes a difference. As to your second point, I do thoroughly clean the build plate with IPA between each print (looking for fingerprints) and they are generally stuck on there pretty good. Thank you for your response.
This version created a really bizarre slice for the top layer of a large ring shape. It printed one short line, then moved over to the other side and printed another one and back and forth, retracting and moving and wasting a lot of time in the process.
The other solid layers (the bottom and all but the top) printed in about 4 minutes each, the top took more than ten and made a mess of it. I'd submit a trouble ticket but don't see any way to do that, so it looks like complaining here is the way to go.
I am normally in Linux, so I booted Windows to try this. I added hardware as "Other" and then sub category to "Other". I cancelled out of the connect printer. Next you have to add the printer tab on the right. Scroll down, you will have to add the bed size, print center and shape. All of these settings must match your printer, but you can get these settings from your other computer. You can adjust the Gcode manually however you want. I have to do this because I run Duet electronics instead of the Azteeg boards. I use gcode programming instead of Marlin.
@fernando-silva I will see what I can do. I need to do a little more testing with this. I know it looks odd that a moderator would be having any kind of issue with MatterControl. But I am currently both using and modifying MC on a daily basis and I hope to resolve bugs or make improvements before others encounter them.
Click on the three dots in the upper right corner next to the temperature reading and select "Show Printer" > "General" and look for "Serial Port". Unplug the printer, check if any COMs disappear, and plug the printer back in to see if any COMs show up. If your printer does show appear, select it, and click connect in the upper left corner.
