@Surgikill I spoke to E3D about this today. The limitation on the 40 degrees is the motor, nothing else. They will releasing a more capable motor in the new year

Just to corroborate this, I received this response from e3d today. Hopefully the ht version does release this month.

Mr.Crispin

This make you wonder why they (E3D) released a product only to advise they are going to update it a few weeks later, i wonder if early adopters with get an upgrade ?

I think you/we/many are overthinking what most/many use their 3D printers for. Most people using their 3D printer for hobby stuff without an enclosure will probably newer have an issue with a 40C rated DD extruder, since they're probably pushing PLA or PET with it anyways.

And those of us with enclosued printers pushing ABS, ASA etc. will just have to wait. A larger "issue/challenge" is the torque/accelerantion dropoff the Roto apparently has (based on Thomas Sanladerer's video).

Also lets not forget about E3D's design methodology of under promise over deliver.

The reason for the 40C recommended limit is going to be a worst case scenario style of limit. where you are running the extruder at max power, on a high flow hot end, on the largest nozzle, in higher than ambient temperatures, with a low temp filament.

There is speculation in the comments (which Tom hadn't denied when I looked yesterday) that the dropoff at high extrusion rates was caused at least in part by running the extruder in stealthChop mode.

@Exerqtor I'm still waiting on more tests. My money is on the stealthchop issue. Apparently around 300rpm is where the problem arises. I'll do some quick math to see if that is around the 8mm/s where he was experiencing drop off.

@dc42 I cant say for certain as I have only tested the preproduction version. But I definitely didn't get the same values as Tom

At 300rpm on the motor, the hobbed gear would need to be around 18mm in order to achieve 8mm/s. At 10mm/s it would need to be around 23mm. I'm not sure on the actual size, but I would bet all my money it's less than 18mm, so that motor was going well in excess of 300rpm. Definitely needs more testing.

Is there any access to the printed mount parts for the Z sensor? I've seen the spacer for the tb but nothing else.

Does the roto toolboard come with scanning z probe coils? I don’t see where to get those separately.

elmoret

@jltx Yes

I have ordered the new tool board to install on my Voron Trident with Micro Swiss NG Extruder, E3D hotend using Duet IR Probe for Z probe. I see in the Duet 3 Roto Toolboard documentation under Firmware notes "Compatible RepRapFirmware version 3.5 or later". I updated my 6HC with SBC which only goes up to 3.4.6, is there going to be any problems using 3.4.6 or do I have to wait for 3.5?

I plan on using a Voron Tap Z-Probe with optical sensor (not Duet IR probe I am currently using) then when I have everything working converting the Tap optical to Piezo from Precision Piezo to work like the Delta Smart Effector so the Tap probe will be a true tap probe like the Delta Smart Effector. Does this configuration look like it will work? Thanks, Ed

@Edkirk you need to use 3.5. It won't work correctly with 3.4.6

dc42

@Edkirk you can install 3.5.0-rc.2 if you switch your package feed on the SBC from the stable to the unstable feed.

Edkirk

@dc42 Where do I find package feed?
