There’s a big buzz around the new 32bit SKR boards available from Bigtreetech. There are now four flavours, the larger SKR v1.3 and Pro v1.1, and the smaller Mini E3 and the E3 Dip. The last two are direct swap in replacement for the existing Melzi board that is shipped with the Ender 3, the larger boards will require a new case to be printed for them like this. So what’s the hype? Well 32bit boards are the future for 3dprinting. The existing melzi board in the Ender is a known bottleneck, this is why many people use Klipper running on a Raspberry-Pi that takes on all the processing and prevents the bottlenecking. The drivers that are now available are just getting better and better, the TMC2209s are the new kids on the block, handle large amps but as they’re not shipping for many weeks, I went for the TMC2208s…Continue reading Installing the SKR E3 Dip mainboard into an Ender3, using TMC2208 v3 in UART Mode and a BLTouch. Setting up current Marlin_2.0_bugfix for the SKR E3Dip with BLTouch enabled.
There seems to be a lot of confusion on using an Ender 3 3D printer about, and the same questions keep getting asked over and over. The printer is cheap so everyone and their grandmother seems to be buying it, which is great, but oh the questions of bed levelling! The very first thing to do is build the bugger correctly. The instructions are nothing but garbage, I didn’t even open mine. Lay all the bits out on a large table, sit down with this video by Tomb of 3d Printed Horrors, get a beer and build it as they do. Allow a couple of hours to do it correctly, I can’t stress this enough, build it once, build it right. If the thing isn’t square from the outset then you’ll just introduce more issues as you try and upgrade/improve the print quality of it. Once you’ve got it constructed,…Continue reading Ender 3 / Pro, Bed Levelling and first use tutorial
