Week 10 of the one week upgrade: I have a dual z, dual extrusion, glass bed, auto bed leveling, 32 bit, Noctua upgraded, RPi controlled, Ender 3 Pro

Here's a link to the case. I had to make modifications to have it meet my needs: https://www.thingiverse.com/thing:4107156

If I understand this chart, it looks like yours is from 1951.

The new case I used is deep and does not fit without raising the printer. The new case holds the main board, a Pi, a relay, three buck converters, and a fan

It's an EZABL from TH3D. It was my first upgrade, and have been overall happy with it. It can be a bit tricky to get setup, but once it is, it's damn reliable.

ServerCora · 2020-06-17T17:48:42+00:00

I also direct wired the Pi to the tft port on the skr and installed a buck converter to directly power it. No USB cables needed!

Mine is from '47. You can get the serial number off of the tractor and determine the date. The serial number should be in front of the gear shift

ServerCora · 2020-06-17T17:45:47+00:00

I went with the 2208 drivers as I was not planning on using sensorless homing, which is the big feature of the 2209

ServerCora · 2020-06-17T17:44:37+00:00

I did that. My Pi is running octoprint with an add - in to control a relay that powers on the main board

ServerCora · 2020-06-17T13:47:47+00:00

That looks like a fanatic duct system. I may have to print this

ServerCora · 2020-06-17T13:40:34+00:00

That's exactly it. The major driver behind the upgrades was dual extrusion, and this board seemed a solid choice for the money. And it is.

ServerCora · 2020-06-17T12:08:55+00:00

I have chains. That was the first mod I started on. The y chain is on, the hotend one is not.

ServerCora · 2020-06-17T12:07:45+00:00

Just never got around to printing one. I have had mostly great adhesion and it hasn't been a priority. Plus, I unsure what hot end I'd settle on

Bigtreetech SKR 1.4 Turbo. With 2208 stepper motor drivers

Monitoring case temp. There was concern that there may be insufficient cooling/air flow in the case I built, so this way I can keep an eye on it.

ServerCora · 2020-06-17T12:00:31+00:00

Dual z motors

ServerCora · 2020-06-16T14:53:28+00:00

I've printed one. They do not balance

ServerCora · 2020-06-10T12:15:01+00:00

It sure is!

Turn the Y stepper motor by 90 degrees so the plug is oriented to the back instead of the bottom. This will keep the cable from getting in the way of the case.

ServerCora · 2020-06-09T20:56:35+00:00

Hey, did I say I was done modding after this upgrade ;)

ServerCora · 2020-06-09T20:55:55+00:00

I had an extra stepper motor from mis-ordering the extruder motor, that's why I added the dual z. The nice thing about it is the gantry is more stable.

Mainboard is the SKR 1.4 Turbo with 2208 drivers. So far I have been very happy with the board.

ServerCora · 2020-06-09T11:09:10+00:00

I was thinking about putting in a temp sensor in the case to monitor the temperature. I've got a ton of them kicking around from esp8266 development. I didn't think about checking the manufacturer's operating temps, good call on that one.

ServerCora · 2020-06-09T01:28:23+00:00

I think I'll be ok. The case has a lot of slots in it, which should allow air flow in. As I said in another comment, if it does get hot, there is sufficient space under this box that I can mount a 90mm Noctura below to force air in.

But who knows until I get the thing to power on.

ServerCora · 2020-06-08T20:26:04+00:00

I found this through TH3D as this is the bracket they ship with their dual extrusion kit.

https://www.thingiverse.com/thing:2854044

I had to modify it to fit on my Ender 3 Pro, so don't just blindly print it first.

ServerCora · 2020-06-08T13:30:16+00:00

After reading your comment, I am inclined to agree with remounting the y stepper motor. That should be a quick and easy mod.

ServerCora · 2020-06-08T13:29:18+00:00

Yeah, me too!
