My Eustathios Spider V2.5 Build With Klipper

3D Printing HercuLien and Eustathios

I’m attempting to bring my Eustathios Spider V2 back to life with version 2.5.

I’m using an SKR 1.3 with TMC2209 drivers and sensorless homing for X and Y.

I still have a few issues to work out. Not sure why but X and Y axis are not working correctly. I switched the wiring but X is still moving when I try to move the Y axis. Once I get this worked out I can work on sensorless homing.

I need to get the display working if it will with Klipper.

Here is my current config:

I’ve gotten a lot farther since this last post, My Z rotation distance wasn’t correct causing me all sorts of issues when I was trying to setup the BLTouch.

My next project will be making sure it can extrude filament. I also don’t have the display working.

One day at a time…

Good to see! I did something similar just recently, upgraded my Eustathios from Repetier/RAPS with Arduino due to Klipper/BTT Manta 4 with TMC5160 stepper drivers. Didn’t bother to keep the old monochrome display. Installed a pitft70 touch display and Klipperscreen. Much better than the lcd. Works quite well already, although I have to tweak some settings. Pressure advance does not seem to work (with 50cm bowden and 2.85mm filament). I’ll post more details later.

I recently got a Bambu X1C and decided why not print the Eustathios Spider V2.5 parts in Burgundy Carbon Fiber PLA.

I’m not having much luck finding the 380mm TR8x8 Integrated Leadscrew Steppers on the BOM. The link doesn’t appear to work and I wondering if there is a good source to get 2 of these.

Thanks,
Brandon

Cut 20mm off the end of the 400mm version of these? (I know the preview says 100mm, but you then can select the 400mm version.)

This item on aliexpress says “Screw length can be customized” so you could ask. This one lists a 400m option that you could trim 20mm off.

I tore down my Eustathios Spider V2 to just the frame.

Hopefully I can get working on installing the new printed parts. I still need to order the Nema steppers for my Z axis.
