One of the things I've found on the rare occasions that I remember to clean my Z-axis lead screw is a ball of super fine fuzz at the top of the screw. This is basically almost invisible stringing that is occurring during large moves that has gotten blown around by the fans and has found its way onto...

Update: I checked with Tech Support, and they said it was OK to try some oil, but VERY sparingly to avoid it getting down into the motor. I used an "acid brush" ( https://www.amazon.com/RAM-PRO-Flexible-Horsehair-Bristle-Tubular/dp/B01LXNQW9W ) with a single drop of high viscosity silicone oil ( htt...

Thanks for the comments! I thought about the infil initially. I'm using 3 perimeters, and that's usually enough to kill a lot of "ghostling" from the infil. The print is mostly hollow, although the wall are thick enough that there's a tiny strip of infil in them. However, if you look at the results ...

The print with the tightened X-axis belt is better, but only after several centimeters, so I think the problem is best described as "prolonged ringing". X-Axis Belt Tightened.jpg Here are the speed, acceleration & jerk results from an M503 query: Maximum feedrates (mm/s): M203 X200.00 Y200.00 Z25.00...

I have an M2E that is about 3 1/2 years old. It's a home hobby machine, so it hasn't been hammered on too hard. I just ran a test print for a friend, and I'm seeing repeating patterns on the surface of the print in both X & Y that I don't recall seeing in the past, or at least no where near as prono...

Thanks! I'll have to play with that. In the meantime, I got a response on the PrusaSlicer forum about printing multiple test pieces with slightly different processes. The trick is to tell PS that you have multiple extruders, and then you can change settings on each "extruder": http://projects.ttlexc...

It has some features I like, but it's definitely lacking in some features S3D has that I have learned how to take advantage of. I've posted a query on the PrusaSlicer forum, about how to tune your settings as efficiently as I can in S3D, and we'll see what they come back with. I can live without the...

I got my second print job done, and it only took a couple hours instead of 4 after I tweaked a bunch of stuff. I need to fine tune some things. In S3D, I could use copies of the same model, and assign slightly different processes to each one. I have no idea how to do that efficiently in PS. Also, mo...

The variable layer controls are in the Printer Settings. Under "General", there is a check box to turn it on at the very bottom. Also, under Extruder 1, the second block of parameters are the minimum & maximum layer thickness. Another annoying instance of parking related parameters on separate tabs....
