Hi Tom,
Thank you for the reply. You are right, the best thing to do right now is to wait for the V-slot rail to come out and try it in my new build. Regarding the jam you mentioned, is that a Lulzbot hot end? Because I have a Budaschnozzle 1.2 and it started to work great at more than 80mm/s after:
1. I put Teflon tape around the nozzle and around the PEEK insulator. (It had a small leak)
2.

Extruded Aluminum Frames
Hi Tkole!
Congratulations for the design. I am considering building one myself with openrails and I have a few questions.
1. How stable to vibrations are these rails?
2. I noticed that the Z rails are horizontal (also other designs online do it that way), but to increase the width printed area they could be rotated 90 degrees and connect the X carriage perpendicular to the Z sliders. Is there

Extruded Aluminum Frames
I used the blue tape and definitely improved the adherence. I also increased the retraction to 8mm and increased the filament diameter ~15% (2.90 to 2.94) until the bloobs disapeared on the 1 layer cube. I guess the diameter of my filament is not as constant as I thought.
Thank you for the help!

Hi, I have a prusa with a Budasnozzle v1.2 hot end/0.5mm nozzle and a Wade extruder. I am using Slic3r, Marlin and printing 3mm PLA. The temperature of the nozzle is 185 degrees; I have the fan cooling down the filament right before it gets to the heating block.
The retraction of the extruder is 1mm at 30mm/s and I am using a hotbed at 80 degrees with a 5mm glass on top.
I have two problems. 1

Hi,
I did try to recycle used motors not taking too seriously the resistance (4.7 ohms per coil) and just connected them to my 4988 drivers using 12V. The result is burning hot motors that after a few minutes start skipping steps.
After looking around on Ebay, I saw these Nema 17, 70 oz-in torque, 30 ohms per coil and 0.4A@12V motors for around $16 USD/ each. The questions are: are they good mo
