Hi James, thanks for the compliment! Like you mentioned I realized I was going to be bumping into my belt path frequently with my filament and...
You can use one geared Nema17 for your z-axis. That's what I'm using for my Samson build. 5:1 reduction ratio should be plenty of torque, but you...
I did a similar project with a 3 axis auto pipettor lab instrument. I was lucky and the machine had stock 1.8 degree steppers on it. If yours...
Confusion typically comes with talking about stepping. Most people are using 1.8 degree/step motors which is where the 200 steps comes from....
Yes, for a full step it's (8mm travel/1 rev)/ (200 full steps/rev)= 0.04 mm/full step. I said 1/16 stepping not 1/6th stepping, so you'd have...
You should be able to land on full steps with the 8mm lead acme screw that's offered by the parts store. With 1/16 stepping and 1.8 degree...
I have started learning Fusion 360. I guess I meant free software instead of opensource so Fusion 360 would count since it's free for hobbyists...
I'm excited to see your build finished. What firmware are you using for your board? Also what CAM software will you be using to generate your...
I've built a few 3D printers, but I'd like to build either a 4 axis or 5 axis router/or mill. I'm thinking more of a 4 axis lathe type setup, but...
Hi Stargeezer, thanks for your interest! I agree, belt slip on the z-axis pulleys is a concern for me. I'm limited by the length in closed belt...
Got the new 3 screw z-axis setup with my geared Nema 17. Utilizes 77" closed loop XL timing belt and aluminum 25 tooth XL pulleys. Also finished...
Thanks Mark! Currently the print size is roughly 11" x 21" with total build size at 24"x27"x24". I lost a lot of print area in the x-axis due to...
The C-beam is cool and using those actuators would work great. I've always been satisfied with gt2 though and it gets the job done. I do...
Sorry, I didn't think about printed parts in the BOM. You can use their nema17 mounts I believe for X, Y, and probably Z. I'm not sure if they're...
You may need printed parts for the motors and will need printed parts for the extruder and hotend holder. I need to redesign the Y mount for the...
The total cost for this build including electronics, motors, etc is $382, if you go with a leadscrew driven z-axis. If belt driven it'd come down...
I think you can do 3 point leveling with the openbuilds build plate and Mk2, but I've never tried it.
I'll put together an official BOM and get it posted as excel file or pdf. What's nice about it is that it's very easy to calibrate and level. All...
It could be the 1.5" extrusion though since they call that 15 series too.
Hi Patrick, thanks for the compliment! That was a large part of the motivation for this build. I wanted something affordable that could be put...
