Yup, it's based on the Hadron. I relied heavily on the drawings and BOM when I made it, but I ended up machining several more parts than the original design (from necessity) and modified it a lot. It's been a constant process of modifications more than a printer so far.
I had some limited success printing with it for several minor things, but I hope after this round of upgrades I'll have a lot m

Hi Folks.
I've been away from my printing efforts for over two years. Back then I picked up a new extruder feed and took it apart to install and never got back to it until lately. I finally got the extruder mounted, taking all of 15 minutes, but while I was in there I decided I wanted a magnetic build plate so dove in and worked that out. I made a prototype proof of concept and even that worked p

If you're doing a bowden drive then the mass nor bulk of the stepper should make much difference either way. If you're going with direct drive then any weight savings would be better, though I don't think size difference would be significant enough to make much difference.
One wrinkle with steppers is the electrical specs make a difference and need to be suited to the driver. I'm just guessing b

I agree with Eric I think. I can't be sure since I've never had a Bowden extruder and in fact I'm barely scratching the surface with my one printer build as it is, but it seems like the hysteresis would be an issue.
Regarding steppers, the 5:1 ratio is similar to the gear ratios folks are getting with their printed gear set drive systems (i.e. Wades extruder), so it seems just right. 10:1 might

I just recently stumbled on Mr. Berry's delta design. I make things for a living and I am thoroughly encouraged by the clever ideas. I just dig the heck out of this stuff.
Who knows if I'll ever build one, but I did build an Ord bot a while back and just recently dug it back out to blow off the dust and attempt to tweak it for success. I think it's very possible that I will eventually steal Wern

Bah!!
I figured it out. Since cooling was enabled, it was setting the feed rate low as per its settings, just like I told it to.
D'oh.

Repetier
Hi.
First i want to say two things. First, I am loving the Repetier host software. It has several features that I wished pronterface had while I was using that and a lot of others I just liked from the start. Muchos Kudos. Second, I am surprised that I hadn't heard of it before this week. It is so slick and thorough that I would assume it would be the default, go-to host and word of it would perm
