FT-5 R2 Part Cooler

I've downloaded and printed several diff part coolers from tverse, and none seem to fit. Are the dimensions for the extruder assembly diff between R1 and R2?

are you sure your machine is printing dimentionally accurate? parts might look right but if steps are off on x y or z part shape can be distorted...how are your test cubes? 20 mm on all sides? just a guess but happened to me...

I though about that...so I printed off a cooler (https://www.thingiverse.com/thing:2334442) on my FT-5 R2 and another one on my MakerSelect - they both matched.

I initially started out on the FT-5 with yellow PLA from FT. I noticed the corners of the cube would curl up and looked soft. Switched to Black HatchBox PLA and the softness looked to still be there but much less.

Printing at 210/60

Am able to print a benchy but it does not look very good.

There is a part cooling fan that works well for the stock extruder on the Google drive where the firmware is located, you should try that one. To answer your original question, yes, the extruder mount is different between the R1 and R2. You can see the difference in the manual.

I will print it off tonight

I am at work and would like to order a fan for it - is it 40 or 50mm?

Anybody have picture of one of these installed?

Yes. If I remember correctly, the hotend is higher up on the R2.

RC1....

Does anyone know of a part cooler for the R2 that uses a 5015 blower fan?

I always wondered about the "official" part cooler for the FT-5... at least the one that was made for the R1. It's a symmetrical design, but the actual hotend is offset... so the ductwork provides 2/3 of the cooling on one side, and 1/3 on the other.

I haven't redesigned it yet, as I'll build something completely different when I switch to a Bowden hotend. But I always though that was interesting.

That cooler was designed my @djcdude95 as a quick cooling solution. He did not spend much time on it and I'm sure he expected it to get replaced. Yet, it really hasn't. There is not much else publically released that outperforms it with the stock setup.

I've been working on a combo part cooler and BL Touch mount, which I'm currently working on in OnShape here:
https://cad.onshape.com/documents/b4169da071cd8a4117c0da4d/w/5ed31517b876c3d6ef6d58c0/e/c7f2c0b38ed6215297e49705

It's still very much a work in progress. I'm currently trying to get through an ABS print of the cooler part without blowing a fuse in the printer. Seriously irritating, but that's in another thread.

There are three main parts:
1. Carriage attachment. This attaches to the back side of the carriage by replacing the 40mm bolts with 45mm bolts. You'll also need to add the X Offset piece as well, otherwise you'll crash the part into the y axis cable chain when homing X. The slot on the side is for the BLTouch attachment.

Part cooler. This bolts onto the carriage holder. I haven't found a final design on this that I like, but I think the one I've got now is pretty close.
BLTouch attachment. Useful if you have a BLTouch.

To attach things together, I use heat-set M3 inserts available on Amazon here:

The fan I'm using is here:

As I said up top, I'm very much in progress on these parts, and plan to do a full write-up on them (including BLTouch) when I'm done. However, if anyone wants to improve on what I've done, feel free!

Thanks,
