Hi all,

I just wanted to share that I uploaded to Thingiverse a Lead Screw end part for the Heavy version NEMA 23.
Since I want to use 12 mm lead-screws i.s.o. 8 mm I needed to adapt this piece. It can house a 62012 bearing.
If you also want to use 12 mm screws, you can take advantage of it.

Thanks to Topsie for the wonderful design !

Cheers !

Thanks ! I plan to use SFU1204 so it will be usefull

Marco64 do you plan to modify the X & Y axis nut holder? That is all I see that needs to be changed besides the anti-backlash nut I already posted.

@streetdoc Yes, as soon as I checked the changes I will publish them too.

@Marco64 are you going to stay with NEMA 17 and T8 for the Z-axis?

@streetdoc I will stay with NEMA17 and T8 for the Z-axis. Only if there is a good reason to upgrade to T12 / NEMA23 I will do so.

I just uploaded the Y-axis nutholder for T12 to Thingiverse. Nut is fixed using M4 screws.

@Topsie For the T12 Nut holder of the X-axis to have enough space, the Y-axis Interior top pieces should be used that are named YAxis_InteriorTop_Right_NEMA23_T8_to_T14 and YAxis_InteriorTop_Left_NEMA23_T8_to_T14 right ?

However these pieces put the axis of the motor 11 mm more backward than the T8 version, right?  Is there a reason for this to be exactly 11mm ?
If it would only be 10 mm, we could use the T12 Y-axis nut-holder also for the X-axis. I hate to add yet another piece if it is not really necessary.

@Marco64, could we print a 1mm shim to move the T12 nut holder that far?

@streetdoc, I added a 1mm thicker nut holder for the X-axis to the Thingiverse thing of the nutholder: https://www.thingiverse.com/thing:4546903

I marked it with the letter 'X' to easily make the distinction between X and Y axis nut holders.
