In my inventory of spare parts, I seem to have acquired a Titan extruder. I was wondering if I needed to change any of the setting in firmware, or whether or not I could accomplish the same in simplify 3d w/o firmware changes. I think the titan is geared as opposed to direct drive.

I also have an EZR Struder™ on order in case I need a backup... because the original EZ Struder is not cutting it.

Any ideas or links appreciated.

You will need to adjust the extruder steps/mm. If your firmware needs to be recompiled to adjust it, and you don't want to do that, then you should be able to set the correct steps/mm using the M92 command in your slicer start gcode script instead.

I use the titan with my Duet and it works fine. Need to go through the usual extruder callibration, but I love the Titan. I know Bondtech QR is the cadillac, but the Titan has really served me well.

Thanks guys;

I think, The line I need to change reads as follows;

#define EXT0_STEPS_PER_MM 92.4 // EZStruder

The titan documentation has the following; 200 * 16 * 3 / (7.3 * 3.142) = 418.5 <does this sound correct.
I know the titan turns 3:1 but the number is not close... I guess I could test the extruder by measuring filament.

Thanks for M92 as well. I might give that a try before i change firmware.

---I have been having some grinding problems. I had the same problem with the EZ struder; and also the EZR struder. So the extruder may not be the problem.. perhaps the nozzle is.

My M92 is currently set at 401. Much closer to your number. I'm on RepRapFirmware.

I set mine to the recommended number (418.5) and it was spot on when I measured it.

Note that the titan (as it comes) tends to flatten one side of the filament due to the flat idler bearing, especially when printing PETG. I made this to combat the issue:

I can now print reliably in PLA, ABS, PETG, and TPE, all with absolutely no tuning of the extruder tension. It seems like a worthwhile upgrade to me.

Thanks very much for your help.

I removed my .4 Nozell from my E3dv6 and I have a .5 coming in from the UK.

When I turn the extruder without the old Nozell in place it takes quite a bit of resistance to get it to grind.
My thinking is that the old Nozzel is just worn or clogged.

If i have to replace the whole hot end then I am going to replace a whole lot of parts. I was considering the V3 effector but I don't see the need for auto leveling because the V2 printer is easy to dial in. Thanks again.

Here is me just showing off; http://www.thingiverse.com/thing:2305229

Also noticed that you can set the extruder speed in eprom using the menu. There is also a max speed as well that I think needs to be adjusted.
