Extruder for Rostock Mini
Hi guys I'm trying to build a rostock mini, but a bit confused with the extruder design. From the RepRap wiki, the extruder uses a special kind of stepper motor ( the one with a big cylinder on top,...

I had a similar question. Check out the link: [forums.reprap.org] Its a geared extruder. In my opinion, worth it.

You can also use a stepper without integrated gearbox with some of the geared extruders. This option will be cheaper and you will be able to set your gear ratio yourself. It is better to get stronger...

Are your steps/mm correct for the tower motors? When you ask the printer to move the hotend 10 cm lower, will it really move 10 cm? Is your delta radius and diagonal rod length specified in the...

Thanks for the reply, buddy. Got some clue from IRC, "check jumper under Z stepper driver. should be 3, and check that all have metal in them (Ive seen empty jumpers before), also check soldering of...

that's probably a wrong configuration of the probe dimensions. It is found somewhere in the firmware (yes - sorry ;-)), something like z_probe_offset or the like (i can't check at the moment). It...
View ArticleRe: Z moves faster than x and y
damn ,that could solve my problem, too. I've got X and Y directions calibrated very good, but in Z it's printing about 1/3rd too high every print. I'll check this this evening, I guess there could be...

Rturnock, I've seen that and looked at many different pictures. It doesn't tell me HOW the LCD is mounted. Rich has an LCD adapter in his github files but I can't figure out how it's used to mount the...

I am not sure either how he did it. Here is his adapter for mounting the LCD [github.com] you will notice there is a way to bolt something on at a slant to the more solid part. The part that has two...

Looking again at RichRap's LCD adapter part, the part is printed upside down. If you turn it over, it will attach to the under part of the top frame on a 3DR Delta and hold the LCD case. I was wrong...

Hi Charlie Yes that's the one I 'Cherry picked' :) But I've now found this one [www.thingiverse.com] that does away with the probe in favour of using the actual hotend. Seems like a more efficient...

Hi Everyone. I was absent for a little while because of an issue with the forum--I was getting a message that I was banned, but I really wasn't. And then things were busy at work. In any event,...

I did see that one too but it relies too much on the nozzle tip being completely clean prior to calibration. I guess a simple wipe script would solve that problem. I'm going to hold off auto bed...

welcome back, John. Thanks for pointing out that picture on Rich's site. that explains how the LCD adapter mounts to the printer. the adapter doesn't line up with any holes in his LCD cover backplate,...

If the printer's already up to temperature it should be fairly ok I'd have thought. The alternative is have the printer do retraction at the end of a print, then again before attempting to level. That...

Hi Guys I've not had any issues with a 'dirty' hotend since I swapped out the Jhead for the E3D. As soon as I have the new hotend probe up and running I'll post a report and some pictures. As far as...

QuoteAndyCart The biggest issue with changing an effector is heating up the hotend to be able to pull the bowden tube out and not burning my fingers in the process ;). For the sake of your fingers,...

Just been playing with some thin walled prints and ive noticed the printer is acting a bit strange. The end effector seems to slow down slightly every couple of seconds which causes a slightly bulged...
