Hey,
Does this requires the E3D heatsink to be installed not in its direct way inside the titan but outside?

Thanks

Hi, what is the X and Y offset ?

  • Posted with 3D Geeks Thingiverse Browser App

Hi,

I think that values are:
12mm:

define X_PROBE_OFFSET_FROM_EXTRUDER 38 // X offset: -left +right [of the nozzle]

define Y_PROBE_OFFSET_FROM_EXTRUDER 5 // Y offset: -front +behind [the nozzle]

18mm:

define X_PROBE_OFFSET_FROM_EXTRUDER 41 // X offset: -left +right [of the nozzle]

define Y_PROBE_OFFSET_FROM_EXTRUDER 2 // Y offset: -front +behind [the nozzle]

I am not 100% sure, because I did that some time ago. You can always measure that values in the CAD model.

Do you plan to update to mk3s / R4 extruder ? Thanks

Sorry, but I am bit out of 3D printing till the summer, so not really.

Hello

Is it possible to make a version with 50mm rod spacing?

There is always an option. Feel free to remix it. You can find .step file in files section.

am I worng or there is no filament sensor in your build¿

There is no filament sensor. But feel free to add it. You can find .step file in files section.

Hi. I am not sure if you have noticed but the mount for E3D has changed since R2 revision. The mount for the cover and body does not fit from your step file. Could you please fix this problem? Thank you.

Thanks for noticing, but that works for me. It's not issue but it is made in that way with a reason. I have checked and design is the same as one on Prusa website.

Did this get rid of the 602 issue with inconstant extrusion? It has theorized that a 3 ;1 extruder fixes the pulses from TMC2130 micro stepping removing the inconstant extrusion. see https://www.facebook.com/groups/prusacommunity/permalink/881837412156992/ and https://github.com/prusa3d/Prusa-Firmware/issues/602 also does it remove the vertical banding see https://github.com/prusa3d/Prusa-Firmware/issues/1289

Hi, I don’t have any problems like you mentioned at all, but I won't give you any guarantee. I use this on two of my printers and it just works great.

Can you add a version from BlTouch?

Sorry, but I am quite busy and there is no time for designing for next few weeks. In files section you can find .step files and you can modify it by yourself.

This is awesome!

Any chance you can also create a version to hold a 12mm version (LJ12A3-4-Z/BX) of the inductive sensor?

Version for 12mm has been added. Happy modding ;)

Thanks. Yes there is possibility, but maybe in next weeks (maybe next week, I can't promise anything), because I am full busy for some time now. Otherwise there are .step files and you can modify it by yourself.

That doesn't look like the stock PINDA sensor. What model is it, and did it require a firmware recompile to make it work?

There are two versions. On the second picture there is stock PINDA and on the third picture there is LJ18A3-8-Z/BX sensor. And for LJ18A3-8-Z/BX you need to recompile firmware and correct sensor position numbers, but for stock PINDA there is no any need, if you are using it on MK2s for example.
