@see3d I will be using Nylon printed parts. What you are attempting to describe, fan fold paper? :S :) edit: I think I understand, place a tube (an enclosure inside the enclosure ;)) around the...

I think I saw another printer that used something like a big clear roasting plastic bag with some positive air pressure. The opening at the top of the bag will be tied to the hot end. That way the hot...

I just lowered the Z 100mm and measured. So the 55.5 steps per unit is pretty close. I guess I just assume 55.5 works for X and Y.

Thanks. In my configuring I was told to make sure EEPROM was commented out. So I will wait until I play with that. Haven't made a first print yet. So I understand. I'm tunning a delta with mechanical...

Getting the heat exchangers to mate up with a stepper on the extruder may be a bit fun. They sort of expect the heat to depart in all directions. Put another way, they don't design them with a good...

Hi Andy, I know we've already spoken in another thread. Is there any chance your parts will end up on Thingiverse? I'l planning on using 20mm extrusion for my delta, and your printed runners look like...

Hi Disneytoy Steps per mm for x,y and z just sets your z travel. Get that dialled in correctly first. Then create 4 scripts to move your hot end to the base of tower 1,2,3 and 0,0 (centre of print...

@uncle_bob New territory for me, so I look to injection molding parameters of PP/PE. To reduce warping the mold will open when the parts cool to ~130F (54 C). So that is one temperature that I'm...

Hi Rick Yes, I'll post them tomorrow along with my other .stl files. I saw in your thread that you have your framing components sorted. You may want to look at my .stl files for the bearing holder...

My *guess* is that if you want to stay in the low shrink zone, you probably want 60C +/-5 for your heating target. That's a bit warm for PLA parts. Probably not to bad for ABS. Likely fine if you...

@uncle_bob, I agree with your assessment, a little bit warmer would probably be better. How tall can you print an object before the part slumps at 60 C ± 5 C (140 °F)? :S

I posted a video of some of the first rough moves on my build. It's just barely assembled, a lot of the components are loose. Now I have to sit down and work out the tuning and geometry measurements...

View ArticleRe: Can anyone explain how to use M666 Marlins?
The numbers in M666 can go both ways (+ and -). If you have a typical Delta and it homes at max rather than at min, the offsets still work. They just work in conjunction with the settings for bed size...
