Re: Rambo Heat Bed Terminal Melted

Re: robotdigg steppers

I use these for my extruders. They can run at a lower current with the same torque as the stock motor, so they are much cooler.

Re: Surface Quality Issue with E3D Cyclops

I'd say try these: 1) Canola oil. This will reduce friction in the bowden and also reduce the sticking at the heat break. Not exactly a long term solution but worth a shot. 2) Better heat sink cooling. Do you have even more problem with PLA? The heat sink on the Cyclops is kinda wimpy. I also notic...

Yes, I do indeed see this artifact on my Cyclops as well. I can't tell if mine is as bad as yours; not to be rude, but your photos are pretty blurry. Do you have a better camera, maybe something that can do macro? My theory is that the filament extrusion is not consistent due to the stick-slip frict...

That is a plugin for Cura. You will copy that file to your Cura plugin folder (which depends on your OS).

Re: Stepper? Servo? What is this?

Here's my take. The pickoff is a feedback device, so it's a servo system. The +/-10V are power supplies to the feedback devices, note they are the same for each axis. Once powered up the PO IN will change voltage depending on the angle of movement. The torque motors are electromagnets. Hook up a joy...

Re: Nylon with Rostock Max hotend for automotive hose connec

ABS glass temperature is right around coolant temperature, so ABS is probably not the best choice as it will lose a lot of strength. Nylon's glass temperature is lower but the strength falls off much more gradually so I'd think this is a better choice. In any case you're going to have a hard time ma...

Re: E3D has released new hotends!

That being said, it's a good idea to not have your heater a lot bigger than your max need. That isn't true. If the firmware hangs or the MOSFET fails and you have a big ole heater, you have a fire on your hands. If you have a reasonably sized heater, no harm done. Hum I think you're actually agreei...

Re: E3D has released new hotends!

The 40W heater allows for faster extrusion rates That is incorrect. The 40w heater does not allow for faster extrusion rates. Again, the 25w heater is good to 300C which is all the stock thermistor is good for. 25w heaters reduce peak load on the power supply and eliminate thermal runaway if the co...

Re: E3D has released new hotends!

For the same heat output sure, but why ever use the 40W heater? Just for the faster warm-up time? On the other hand maybe it's not the heat loading but to lower the peak power required of the supply. The 40W heater allows for faster extrusion rates and/or higher temperatures, which translates into m...

Re: E3D has released new hotends!

My Volcano came with a 12^2 / 5.6 ~= 25W heater (with the blue wires), that seemed really weird. Is that right or was it packed wrong?

My Cyclops came with a 12^2 / 3.3 ~= 40W one.

Maybe they put 2x 25W heaters with the Chimera to reduce the potential heat loading on the cooling block.

Re: man sized

So 0.8mm * 1.2mm * 30mm/s = 28.8 mm^3/s which is great! I can get maximum maybe 13mm^3/s from my v6.

I'm building a new printer and it's going to get the Volcano, I'm excited to try it out!

I use Cura to automatically scale the fans according to the layer time. And yes I use it on ABS. What can I say, I like to print fast! For ABS my minimum layer time is 5s, minimum speed 5mm/s, fan min 0%, max 100%. This means that the fans will just start to turn on when the layer time is 5s. It wil...
