After more than 4 yrs of owning a K40 laser I’m finally starting a different maker journey by adding a 3D printer to my tool kit. Knowing all the great 3D printing makers on this forum has given the confidence to take on this challenge. My 3D printer of choice to start with is a Geeetech A10. Th…

@NedMan Yes it is Vert’s firmware.

[image] mcdanlj: Actually, it is RMS current. Thanks for reminding me that it is working with a stepper motor and not a DC motor! My turn to slap my palm to my forehead! Here is a great quick and simple explanation with pictures and graphs! https://www.amci.com/industrial-automation-resourc…

This drove me nuts when I was first playing with stepper motors! I spent a bunch of time with first measuring DC current across a single winding with my VMM, and then the rare experience of actually using all four channels on my oscilloscope to visualize what was going on in a running stepper. …

Thanks guys, I’m learning so much here. :slight_smile:

Finding and ordering back up hot end thermistors for my A10 turned out not to be as straightforward as one would think it should be. [image] Hot End Thermistor for a Geeetech A10 3D Printing So after getting a MINTEMP error on my A10, after first setting it up, (was a loo…

Installed the TMC2209s and installed a nice custom firmware for the A10. [image] TMC2209 Driver Upgrades to a Geeetech A10 3D Printing Upgrading my new Geeetech A10 printer to use TMC2209 drivers in place of the A4988 drivers to make the printer quieter. I could have use…

Been slowly working on calibrating the printer and playing with parameters. Installed a 4mm glass bed and everything is flat and level. I’ve been going by this site that @HalfNormal pointed out [image] Great all in one 3D printer calibration and tuner tools for beginners and expe…

Depending on the brand of pla it’s usually between 200 and 210 for a decent print. I have not personally been able to replicate his Bridges as I end up with something akin to what you get. Unfortunately cooling is a two-way street. Sometimes it’s great and sometimes it’s not and it all depends on th…

Ok glad to know it’s not just me. I suspected there might be something with the way his slicer is setting up the print. He provides the .stl file for the tower but then I would need to figure out how to change temp as a function of print height in Prussia slicer :crazy_face:. Sooo many things to lea…

First: I don’t concentrate on temperature towers because one of the things I enjoy is working out how to avoid most need for bridges in my designs. When I am designing functional parts, the strength from additional layer adhesion from printing towards the upper end of the range is usually a win for …
