E3D Titan on the MK2  

Re: E3D Titan on the MK2

Ordered the parts yesterday so I'll be giving it a try after I master printing with ABS.
I'll report back on how it works.

Re: E3D Titan on the MK2

I've got a BigBox which i upgraded to a Titan, great piece of kit, well made and better feeding, no need to calibrate each filament for extruder steps any more.

Re: E3D Titan on the MK2

I have been slowly modeling something like this myself.
So it is nice to find one already done by someone else.
Because mine wouldn't look anything like this and would have moved the hot end out a bit from stock.

I already have a Titan lying around the house.
So I will just need a few different bolts to make it work.
And being able to swap to a pancake motor for lower extruder weight is always a good thing.
When I get home this evening I will definitely start printing up a set of these parts.

Re: E3D Titan on the MK2

I've ordered the printed parts from a 3dhub and will give it a try ! ( I don't print ABS)

Re: E3D Titan on the MK2

This is looking great. The feeder is the one thing that's been giving me the most grief with my MK2. So going to a E3D Titan sounds terrific.

Too bad I have a multi-material upgrade on order (i guess they will ship eventually), otherwise i'd be printing now.

Re: E3D Titan on the MK2

I printed the 3 large parts with PETG and the 2 small pieces on my Markforged from Onyx since it wasn't busy.
If all goes well I should be installing it this evening when the 40mm M3 bolts get delivered.
Now the carriage for this just needs to be remixed with Aaron's carriage for the cable chains.

Re: E3D Titan on the MK2

Printed the parts this past weekend n put it together yesterday. So far all good just needed to take it apart to take out some backlash. So for someone doing it make sure you remove the backlash while assembling. Still going to tweak the speed and acceleration in software.

Re: E3D Titan on the MK2

I've also successfully assembled the titan. Not had much time to play with the settings as yes though. I did find the titan a very tight fit, I'm thinking I'll need to increase the scale slightly - I had to bend the top part down slightly to get the screw in to the piece that holds the bearings.

Re: E3D Titan on the MK2

I tested the max feed rate in PronterFace and found I could only get about 2400mm/min without it missing steps.
So I found out how to change it in software and I am running some prints now to see the results.
Looking at the Gcode from Slic3r it didn't feed at rates above this, the only time it went higher was when it was retracting.

Re: E3D Titan on the MK2

I've recieved my Titan yesterday, and just bought the original fan duct from e3d.
Will put it together on the weekend.

I've also bought a 0.9 degree stepper motor for the extruder, the doubled stepping coupled with the 3:1 ratio of the titan will give me some headaches for sure. Calculated the E Steps will be 837, which is as reprappers know close to the wade"s extruder stepping of 900.

The extruder pulley from the Titan looks rally good, much better than Prusa's brass pulley.
That and the feeding mechanism without the two filament tightening screws should make this upgrade worth it.

Re: E3D Titan on the MK2

I replaced my stock extruder motor with a pancake motor.
270g down to 125g
I am going to see how it does with silent mode.
Hopefully it still has plenty of torque without having to use high power mode.

Re: E3D Titan on the MK2

So, when I installed it without changing anything else I got tons of skipping and it was not usable at all.
I went into the firmware and bumped up the current a fair amount (probably more than required)
But so far in testing it has not skipped yet with pla running through it.

Re: E3D Titan on the MK2

I've upgraded to the Titan today.

Currently on my third print, only a few minor issues to iron out on my Prusa. (x-belt check not working anymore, broke a screw off on one of the titan parts)

Will post pictures soon.

@joseph.k

I've bought the 0.9 degree stepper, and got a lot of extruder skipping at first. researched a bit, and found out that the motor current is not enough
You can use this gcode in the custom gcode section in the slicer
M907 X640 Z830 E800 ; set Titan Extruder Current
i've bumped my Extruder current to 800mA as you see there.

I've done everything in gcode to configure the Titan, the extruder steps, the extruder current, and the PID tuning.
Connecting the Extruder motor to the mini Rambo with a reversed plug will run the extruder correctly, in the right direction now that it's reversed.

So i can keep the original MK2 firmware, and not always compile it when there's an update.

Some things i love/hate about the S+E's Titan implementation compared to Prusa's are:
e3d plus:
+ love the brute force of the thing
+ no load or unload filament necessary, just pull the lever and pull the filament out and ram a new one in. that's it, no filament loading
+ goodbye pesky tension screws!

e3d minus:
- bought the original fan shroud (the blue one), and it's quite loose. a #D printed one will fit better, but Prusa's implementation was quite tight in a good way

S+E's implementation plus:
+ love the quickly changeable filament fan
+ quickly changeable silicone sock on the hotend
+ quickly changeable nozzle (in theory, haven't tried it yet

S+E's implementation minus:
- complexer than Prusas carriage to disassemble the full hotend now, hope i don't need it
- air flow of the fan adapters is sub par, i'd say the two air outlets output only 30% of what the fan is capable of. quite a bottleneck here. although he made a few new ones after i gave him some pointers

Re: E3D Titan on the MK2

With the big fan (GB1205PKV1-8AY) and it's adapter it looks like a tank now scrubbing along the heatbed. I imagine it's quite heavy and i loose some speed, but the upgrade is worth it!

How's that Pancake motor working out for you?

I haven't had any major problems with the big 0.9 degree stepper, except for printing with 0.25 nozzles. 0.4 works fine

I'm thinking about switching it out to a pancake motor (with added current), because i've got some ghosting which could be due to the whole x carriage weighting a ton.
