Re: Taulman 910 warping

I print a lot of nylons and you really have to stick to the 45°C on the bed - Elmer's brand glue stick on PEI has always worked well for me even on printers that aren't enclosed. I use a brim as well if the part has geometry that is going to make it prone to warping or if it has a small footprint. Y...

Re: mosfet controller board to extrude

The 12v supply to that board is limited by a 12v regulator on the main board and is limited to 3A but this regulator supplies the extruder fan, part fans and the LED lights - you don't have a lot of room when you add everything up. The FETs are NOT the bottle neck.

Re: An end to jams - blowers are better...

Definitely use a high quality thermal paste design for CPU's - you'll probably double the heat transfer.

Re: An end to jams - blowers are better...

Did you use thermal paste on the heat sinks?

What does the filament look like if you cold pull it?

Have you checked the entire pathway for obstruction - stuck filament - PLA loves to stick to metal - especially warm metal.

Re: An end to jams - blowers are better...

I haven't been able to measure any significant temperature difference between the two extruders at the various points I measured through a large range - what was your issue with the right extruder? - perhaps it's not cooling related? Fans aren't designed to generate any pressure - they can move a lo...

Re: Leaks after nozzle swaps

You have to torque with the block above the highest temp you are going to print with - otherwise everything comes loose and leaks. This is not clearly explained in the Raise instructions. The gap is to ensure that the nozzle is torqued against the heat break and not the block. I heat to 310 then tor...

The MaxFit MFSH-2000TSX-RS-R

Made this spool holder to fit those pesky 75mm spools into the Pro2 and still allow the doors to shut. Clips securely into place and is named in the spirit of Japanese motor sports.

Re: Extruder Jam and stuck fillament Pro2

Yes it's a common issue unless you address the inadequate cooling of the heat sinks. Just do a search for "jam" and you'll see. What filament are you printing? It's more of an issue with long PLA prints - you could switch to PETG or ABS and probably get by.

Here's a torture test I did using Raise PLA - I printed at 220 with the bed at 60 and the printer completely closed using the Raise standard template with a few small changes.

Re: Fan Upgrade

Nice - should do the trick - so you retapped the block to take the e3D heat break?

BTW the blower mode works pretty damn good:

Re: Left Extruder jams

The image of the filament looks like heat creep to me - you can see where the rollers squished the softened filament.

Re: Left Extruder jams

I don't think that's wear as the whole thing is made with SLS printing out of black nylon powder. Probably debris from filament that's worn off by passing though the extruder. Going to have to use the steel rod and find out where the obstruction is as per Raise instructions.

Re: Tray Size

Can you print the part in two or more pieces? You can bond the pieces together after - not sure what the part is for or if it will be under any stresses. You can print in ABS and solvent weld them with just acetone.

Re: Preparing to swap nozzle - Any last minute advice?

I highly advise torquing the nozzles over the highest temp you ever plan on printing. If you torque them at room temp - even really tight they can come loose - has happened to me. here's what I do: remove hot ends from carriage use Raise instructions for gapping new nozzle but gap to 0.25 - tighten ...
