Get rid of the 'spring' coupler OR lock it with a clip if you still have the z motor on top. The coupler is acting like a spring. You can flip this over and put the zmotor at the bottom, this is said to improve things. This is my next step to fix mine. Check your vertical carriages, esp the nylon wh...

I run small 36oz/in nema17s in a small reprap printer I made. They work fine. I can get 50-60mm/s using PLA.
Typical ones were in the 40-42oz/in range.

I got them from stepperonline.com, they have ship points worldwide.

An i3 or dolly is a good choice, reuses most parts, and frees up the Z axis.

I would pitch a SmartRap mini, cause I re-cadded most of the parts....but you have little parts reuse, its works best with a e3dv6 hotend and bowden setup.

Hi, This week I have signed up here and the RepRap forums. Both seem to be kinda low traffic. Seems like the 'hobbiest' group is small, where the 'I just bought X and assembled it' group is much larger.

To lube, or not to lube. That is the question. Use a 3-in-1 oil, mine says sae20, this will keep working the grit out. When I get new bearings, I clean them in some mineral spirits, and work them thru with a small bamboo skewer, then dry them. Then I add some 3in1 oil and work then thru again, and ...

i use cheap OSB for the frame and https://de.aliexpress.com/item/Funssor-PRUSA-I3-6MM-HEATED-BED-SUPPORT-aluminum-alloy/32809253205.html as the y carriage. And OSB is like in everything, so look at recycling old ikea type furniture that people put out for trash. Look for tv stands, entertainment ce...

Also I would try isolating the issue by test type. I got a much simpler retraction test from thingiverse to tune my retraction distance. https://www.thingiverse.com/thing:2535405 Get the retraction configured then try a larger print. This helped my quite a bit, and is much faster than the xyz cube. ...

Yes I have !! I should have a webpage up soon with a full discussion, photos, Bill of Materials, and reworked CAD parts of this design. I spent about 8 months working with the original, then re-working parts. First I redrew the CAD of the original parts, because trying to tweak them in STL and mesh ...
