Re: Printing ABS

All ABS filaments are not created equal. I've had good luck with Hatchbox. My current go-to is eSun ABS+. I never got good results on larger parts with eSun ABS. I have tried other ABS filaments and had warp issues. What bed temp are you running - and do you have the fan covers installed, doors clos...

Re: PETG on Pro2

PETG temps depend on the brand and color - I print small vase-mode test parts at different temps to find the best layer-bonding strength. Usually lands between 240C and 270C.

Re: Rough prints against support material

Check your separation layers. For disolvable support you should have separation at zero.

Re: Poor quality and printhead drag

Without knowing where you are starting from, higher or lower doesn't mean anything.
With overhang, layer thickness vs extrusion width is a significant factor.

Re: Poor quality and printhead drag

Hard to provide any sort of advise without knowing your current print parameters. I don't have the factory settings memorized and have never tried printing with them. Nozzle size, extrusion width, layer thickness, temperatures, speeds, etc ... Assuming you are using the .4mm diameter nozzle, I would...

Thanks a lot!


I'm using a 2-flute 1/8" diameter endmill with an 1/8" shank to fit into the Dremel.

Re: Bracket/Fix for N2 Rotating Z-Axis Ball Nuts

The ball nuts are not bolted tight to the print bed. The bolts are loose to prevent any binding that might occur due to minor misalignment of the linear motion bearings, rods, and the ball screws. The combination of the loose bolts and play in the holes means that the ball nuts are free to rotate se...

Re: Can't place order from out of the country

Thanks, but I'll be back in the US on Wednesday. I'll just place the order then. It's nothing I need in a hurry.

Can't place order from out of the country

I live in the US and am currently traveling in Asia. I was going to pre-order some boots and a couple other parts. The web site keeps throwing me over to the .asia site where I don't have an account. I have tried 4 different web browsers and all behave the same. As soon as I click on the https://www...

Re: Raft Alignment

I'm guessing that if you rotated you build plate 180 degrees that the raft would be building in a new area. That gets you 2x the life.

Re: Drying filament under vacuum

I work for a major manufacturer of high-end vacuum equipment. There are several types of dry pumps which use no oil, but they are far more expensive than what I'm using. What I've seen equipment to separate the water from from the vacuum line is also very expensive, so I don't plan to go there. Deal...

Re: Drying filament under vacuum

I dug through the filament archives and found a neglected spool of Taulman 910. It had been stored in a bag with silica gel, but the humidity indicator in the bag showed at least 50% RH. I weighed this spool on my cheapo scale with .1g resolution (but also a bit of hysteresis, so it's not perfect) a...

Re: Spiral Vase - Sphere Printing

To fill in the gaps, the machine would need to be printing concentric rings with almost zero change in the Z dimension. FDM printing won't print unsupported material like that. Gravity will win that battle. You can get to about a 45 degree overhang with vase mode - or might be able to get up to 60 d...

Re: Drying filament under vacuum

That last batch of 4 spools and a bunch of silica gel ended up running for about 48 hours before the desiccant turned blue. I exchanged oil in the pump twice during the run and again when it was finished. I froze the water out of the oil and collected about 4oz of water (~120ml). I poured the oil th...
