Re: Missing extrusion at the start of some layers

Worth comparing it to default Prusa Slic3r retraction settings, which I've always found really solid. You have several of the binary options set the other way.

Re: TMC2130 Shutting down marlin while homing

I had an issue with other drivers where I was using 0.9 degree motors and 1/32 microstepping and my steps per mm were just too high for the 8-bit processor to handle while also processing bed leveling. It would cause the printer to restart during homing. In my case updating the firmware fixed it, bu...

Re: Tax Return Printer

The glass is for keeping things flat and easy to reapply tape/glue to help adhesion, but thicker glass does make it harder to heat. There are a few temperature upgrades, one being to insulate the bottom of the bed, one to replace the heater altogether with a mains voltage silicon heating pad, and on...

Re: I start to hate PLA! (PETG vs PLA)

I assume you printed that in the same orientation as the picture? While that makes the most sense for the shape of the model, the forces that you are introducing in the battery clip are shearing the layer lines, which will make it break easily. Any time you are bending a part you want that bend to h...

Re: Please Help setting up Anet A8 Slicing

I don't have this printer so I don't know all the specifics, but I can help with Slic3r. There are 4 tabs at the top: Plater, Print Settings, Filament Settings, Printer Settings. The plater tab is where you lay out your prints. The three settings tabs each allow you to save a group of settings so yo...

Re: Issues with TMC21030 on the GT2560

You can fix the reversed directions in firmware, just change these settings to be the opposite of what they are: // Invert the stepper direction. Change (or reverse the motor connector) if an axis goes the wrong way. #define INVERT_X_DIR true #define INVERT_Y_DIR false #define INVERT_Z_DIR true // F...

Re: Tax Return Printer

Yeah the Tronxy is pretty rickety with the acrylic/threaded rod frame, I'd stick with the other two for better rigidity with the metal frames. There is an immediate concern with the CR-10, which is that it uses a pretty standard 12v 30a power supply to try to heat that enormous bed, so as far as I k...

Re: Tax Return Printer

Re: cheap/upgrade vs. buying an expensive but high quality printer, it seems the benefit of going the cheap route is that you really learn how the printer works, but the disadvantage is you learn this through troubleshooting problems. :lol: To me it comes down to if you're interested in 3D printers ...

Re: Tax Return Printer

The Creality CR-10 is probably the most printer you can get in that price range, and it's been very popular recently so you'll be able to find a lot of info out there for ways to upgrade it along the way. It is a kit but it is mostly pre-assembled so you don't need to do very much to get it going. T...

Re: New build, hot end thermistor reading 800 degrees

What hotend did you buy? A store link could help. Most of the V6 clone hotends use the thermistor defined as 13 in Marlin, so your code would look like this: #define TEMP_SENSOR_0 13 If you have a working thermistor on the bed, you can swap the plugs on the board to see if you can get an accurate re...
