The extra memory in the SKR card and a bit of tweaking lets me drive the two Z motors separately.

WINALIGN 14.3 PRINTERS DRIVERS

There are three more- as I added cooling for the TMC 2209 stepper drivers AND the Z stepper motors, which now get quite hot. The only real noise comes from the cooling fans now. The printer is so quiet I sometimes forget it is running. There are a lot of “How Tos” online, and I can’t really do the process justice here. It took a lot of tweaking and recalibrating to get decent prints again. I’d been using Arduino IDE for a number of years, and still use it for my other microcontrollers. I still hate it, but am getting a bit more familiar with it now. Marlin switched from using/supporting Arduino IDE to Visual Studio Code (yes- THAT Visual Studio, but the open-source version). I’m not giving up Octoprint for their display, so I just use it in “LCD12864” mode, which emulates the “old” display.

They claim it is because I am using Octoprint, which causes serial conflicts. I spent over a week working with their support on it, and came to the conclusion that it just doesn’t work. It won’t work at all in it’s “touch screen” mode with a modern interface.

The alternative was to install a BigTreeTech TFT display. It’s also possible Anet or BTT changed something since the HowTos were made (some were a few years old), that further disrupted things. Some people do claim to have made it work, but I’m dubious. It’s possible one of them fried something in it. I was unable to get the printer’s stock display to work, after more than a dozen attempts from at least that many “How To” posts and YouTube videos online. You have to re-do several connections because the pinouts are different, and there are a lot of options to set and tweak in Marlin. I’d rate it moderately difficult IF you are good at reworking/crimping JST and Dupont connectors and are comfortable digging-in to Marlin code. In fact- I recommend it as the reduction in noise alone makes it worth the upgrade.

WINALIGN 14.3 PRINTERS UPGRADE

It is very possible to upgrade an Anet kit printer’s motherboard to a BigTreeTech SKR 1.4 with TMC 2209 or similar stepper drivers. I just finally got it working well again over this past weekend. Frankly it was a frustrating mess that I didn’t end up documenting well enough to do a comprehensive guide. Okay, so I decided not to share the details of this. So- we’ll see how it goes, and I will review it once I get it. I’ve ordered a new Creality Ender 3 Max, which was highly recommended in some of the 3D forums I’m in as a “work horse” printer I can “count on”. out of it, and the acrylic husk has been remanded to the dump. I stripped the reusable steppers, control boards, Raspberry Pi, PSUs, relays, fans, cables, etc. I’m also more concerned than ever about the fire danger of continuing to operate it, even if I do rebuild the hot end AGAIN. I’m tired of what seems like constantly rebuilding this thing to get mediocre prints for a few weeks before something else fails.

It was in the process of stepping through an auto-level routine for a new print at the time.

From what I could tell- the firmware DID NOT detect an issue as the display still indicated normal operation. Fortunately I was in the room and the smoke alarm I had mounted to the top went off, so I quickly shut the printer down. I’m not sure if it was a firmware or thermistor failure, or bad connection to the thermistor- but the hot end erupted into a cloud of smoke one afternoon. Unfortunately something went wrong and the printer almost caught fire.
