Thanks for the advice. I'll try turning on the fan and see if that does anything, along with increasing the speed. I'd hate to have to decrease the layer height (because it will increase time so much), but I may try that as well if the first two do nothing. It may be more a difference in air flow a...

It's not the "updater" that is broken, it's the software development process at S3D that is busted....

After waiting all this time for an upgrade, I'm still OK with paying for it IF it is all it should be after all this time. I have now also had plenty of time to get PrusaSlicer working as a backup. I still prefer S3D, but if they go to a subscription system, I'm out of here...

Unfortunately, I don't know of a way to do this easily in the current version. This is one of the MANY feature requests that should have been addressed in the phantom "Version 5" that was originally supposed to be out before the end of 2019...

I managed to reduce the same effect on my printer by re-tensioning the belts. After three years, the X-axis belt in particular was looser than it should be. I also cleaned & lubricated the linear bearings. This was on a MakerGear M2E so your drive hardware may be quite different. That main thing is ...

I use dovetails a lot to connect parts for larger models. I also use them to assemble multiple smaller parts where I don't want to mess up the cosmetics by using supports. Here's a magnetically mounted screw driver rack. There are two side pieces for the screw drivers, two end pieces with the magnet...

One trick is to make the top of the hole conical. If the cone is at a steep enough angle, it won't need or generate supports. If the hole HAS to have a flat top or you can't edit the file, you can go into the supports menu on the right side of the main display, and remove just those supports. It loo...

Just a thought: If the blobs are sticking up a little, the layer shift can be caused if the extruder smacks into one. Try a little Z lift & see if that helps.

I always use the SD card after having multiple crashed prints caused by Windows doing something to USB in the background. It may depend on your printer, but if ANYTHING tickles the USB for any reason, my printer (MakerGear M2E) throws a fit. I have a USB connection to control the printer for things ...

I'm using the latest version, and I use this feature quite a bit. At least with regular 3D models & printing, it's always behaved as expected for me.
