An end to jams - blowers are better...

Finally got the hot end cooling mod done and tested today - works very well - here are some pics of the mod. The three blowers added a total of 30mA to the whole cooling on the carriage - main hot end blower and two part blowers. Bottom fin of heat sink didn't get above 35°C with the temp set to 300...

Re: Fan Upgrade

I think the Mosquito is the better route if you're going to switch to a different hot end entirely - smaller, lighter, shorter and more better. I have the design for the adapter plate if you want it.

Re: Fan Upgrade

I got the step from DigiKey - everything should be there? What do you mean by "shroud" - the duct? I linked to the Sunon blower that I am using - there is no CAD for that model as far as I can tell - there is an identical Delta blower that does have a CAD: https://www.digikey.com/product-d...

Re: Fan Upgrade

This is what I really want to get up and running.... I'm pretty sure this 50mm blower can keep the anemic heatsinks cool enough to not need water cooling. Need to set it up and measure the temps on the heatsinks - this thing moves some serious air. https://www.digikey.com/product-detail/en/sunon-fan...

Re: Fan Upgrade

Here's the left part(s) - still optimizing the duct angle and height - got it pretty much nailed down though - you will need 2.5mm heat set inserts and hardware and can use the original M3x8 screws from the machine to mount to the carriage

Re: Fan Upgrade

I have a design that uses two 45mm blowers for part cooling - if anyone's interested I can put the design for the mounts and ducts on thingiverse. This is the part I used - develops good static pressure and responds the PWM very well: https://www.digikey.com/product-detail/en/delta-electronics/BFB04...

Re: Adaptive Layer Height Causing Longer Print Times -SOLVED

Actually ALH CAN save time depending on how you set the percentages of nozzle diameter and overhang - I did a print with it set up to vary between about 0.15 and 0.25 - so the areas that printed at 0.25 would save time over printing the entire model at 0.15 or even 0.2 depending on the model and the...

Re: Printing above 250°...

You can use any K type TC really - and they're easy to make if you have the wire. You can get good wire from Omega - the K coloring convention is yellow for the positive alloy and red for the negative alloy. We used to make them using a small 12V lead acid battery and a block of Graphite - now I use...

Re: Adapted Olsson Ruby nozzles

I like the Solex nozzles too but I've only tried the ruby so it's suboptimal compared to a fully machined nozzle for nonabrasive stuff - comparable to the Olsson IMO. I think the mosquito is superior to the E3D hot end though - really nice to not have to deal with holding the block when torquing a n...

Re: Extruder Jam and stuck fillament Pro2

The only solution is ditching the Raise hot ends altogether or getting the liquid cooling set up. Very sad Raise won't address this - the marketing on the website says the hot end can print materials up to 300°C - wouldn't go past 240 on a cool day with the printer open!

Class action anyone?

Re: "thunk" sound along the Y axis

Ug. More importantly why are these things failing left and right? Simple, motor to shaft alignment. The motor is mounted using a Z shaped bracket with plenty of room for variable alignment and only held with friction from the screws. You ship and jostle around a printer put together in China, shippe...

Does anyone know if these are still around.

Tungsten is at least as thermally conductive as brass BTW.
