Re: Filament stuck in Pro2

That is a dismantle and repair job, I've had to do so after having similar issue. The filament squishes at the feed roller and wont go in or out.

Re: First Layer Quality

It probably comes down to a tradeoff between price and thermal efficiency. The nickel-plated brass (hardened) nozzle conducts heat better than an all-steel nozzle (nearly 4X). Common metals ranked by thermal conductivity Rank Metal Thermal Conductivity [BTU/(hr·ft⋅°F)] 1 Copper 223 2 Aluminum 118 3...

Re: First Layer Quality

Thanks Steve for responding.

Just realised that the Raise3D so-called "Hard Nozzle" is not Steel but brass with coating. Why would Raise3D make an inferior produce that implies it suitable for Carbon Fibre when it is marginally better than the std brass.

Re: First Layer Quality

Hi Markus64

Apologies, this was BASF PAHT Carbon Fibre 1.75mm and printed with a 0.4mm hard nozzle.
First layer at 0.2mm
Flowrates are 100%
Tomorrow I'll try reducing print speed then the others.

Re: First Layer Quality

Please see included photos:
Gear1 on edge shows the first layer (on the right side) where the first layer protrudes all round. This was printed on a raft so this is not hotend to bed calibration.
Gear2 is the top finish, I think this is acceptable.
Gear3 is the first layer on the raft and looks crap.

First Layer Quality

I am printing a gear on a raft. The gear is parallel to the bed with teeth in Z axis The first layer is always; 1) printer with first layer bigger than the rest of the layers. 2) print quality of bottom (first layer) not as good as expected. i.e. smooth finish as if moulded. Please can someone give ...

Re: STL Design Shared

Perhaps a brief writeup on how this is to be used would be great. i.e. print and measure with a dial gauge.......

Re: poor quality prints

Hi Vicky,

Yes both Left and Right Z offset is ~0.02mm. Both are PLA from Raise3d so bot are set at same hotend temp during print.

poor quality prints

I have started having issues with prints, Often the first three or so layers show some "shrinkage" does not happen if I raft. Some pulling away from the bed and just generally very poor quality. I am using eSun PLA and used the raise3d supplied template. I have checked the bed tramming. It...

Sizing to design

Perhaps some can give advice. When I design a part in CAD and want to print it, how do I dimension my design to take into account the final printed part? e.g if I am using 0.4mm print nozzle with PLA what value should I compensate with so printed part is as close as possible to designed.

Re: Filament Runout Sensor Issues with Pro2 and E2

Hi All, I am toying with the idea of designing a filament feed circuit mounted before the Bowden tube. The idea is to monitor filament feed and flag a warning if somehow filament stops/stalls.
Do readers this this a good idea?
