I just tried it and get no errors. It looks like you are on a Linux system so I'm not going to be much help. Do other openscad files work, can you comment out some of the modules to see if it works with out any of them? If it does, let me know which one. it may be that it doesn't like the way I use the rail STL and chop it to length. I don't know.

What version of openscad are you using?

I had sheared the brass nozzle off my E3D last week and got the replacement parts from Filastruder this week. I when with the new V6 heaterblock, thermistor, and nozzle. Here is a comparison of the same part printed at 0.2mm layer height and 0.1mm.
After the installation I had to adjust my max Z height and some of the tower endstop offsets. It turns out the 10" cake pan glass plate is actually

I read your blog. Are you a mechanical engineer? I have concerns about the friction of the belt on the fender washer.
On the endstop switches, the ones you have are meant to plug into the S - + on the RAMPS and have their own pull up resistor on the circuit board (along with a LED). When you flipped the connector, you shorted - and + which took out the fuse on your Arduino. Any high quality snap

Why not connect it to 12V all the time? This is how I do it.

Take a photo of where your endstops are connected on your controller. Good lighting and macro is preferred.

My endstops are wired for normally closed. When I send M119 without any of the switches touched I get

Reporting endstop status

y_max: open

And when I send M119 with me touching one of the switches I get the same thing. I

Wrong. I think you mean set the X an Y min endstop to -1, not homing direction. Deltas home to the max or +1 direction.
Quotestin93r
In your config I see your X and Y homing direction are set to 1, change this to -1 so that X and Y are both at 0 (centered) when the machine is homed.
Move the carriages away from your endstops and run M119. If you see your X/Y/Z Max events then depress one switc

It's alive!
I did make some changes:
I replaced the gold effector with a silver one after I redesign the center opening. The gold one was to deep and did not let the coupler pull the hoten tight so it was floppy. I reprinted the Greg Wade body for use with a bigger pushfit for the .25" Bowden tube that came with the E3D. I modified the design of the Wades extruder so I could use a machined hob

If using Repetier, use the Tower endstop offsets to "move" the endstops toward the print surface.
QuoteWZ9V
My X, Y, Z are still a bit high and I have not even started to tweak the center. About now is when I would appreciate the adjustment screw I've seen on other carriages. I'm stuck moving the endstops on the openrail which is frustratingly tedious but I'm getting there.

I dumped the MakerGear V3 and ordered an E3D Bowden from filastruder.com Time was very accommodating and let me order it with a 0.6mm nozzle instead of the stock 0.4mm.
I modified the effector.scad file to open the center mount to make room for th etop of the heatsink to push through, and then the rescess so the Bowden connector would fit. I used the Birch ply mount as before. I originally trie

Sounds like your direction signal is not being recognized by the driver. You don't have Y-min enabled do you? What does M119 report?

With the probe retracted send a M119 command and copy/paste your results.

You seem pretty sure it'll all work out....if you are using any other experience as a basis for your optimism you are going to get a rude awakening. Please do blog your progress, you have ideas that will be interesting to see the results of. We should all be able to learn something.

On my $15 RAMPS, I had to resolder some of the driver pins on Y and Z. I had to first look at the schematic then trace each connection. Do you have multimeter?

Ok, that was unclear to me. So if the wiring is not bad, then the motor may be.
- scroll to where is shows the stepper motor.
QuoteDelta9380
I did not, but a stepper driver from another motor, that was running that motor fine, it did the same thing. even when I changed the motor and driver from a working tower to the Y tower it still had the same problems. It leads me to believe there is some

If you mean, how it's mounted on the effector, yes toward the Z (center rear tower). Be aware, the use of a microswitch and a bent wire has been abandoned as unreliable.

I did try to play with retraction settings yesterday and I discovered that the heating element isn't able to get to 180 an hold that temp while printing. So, I'll wait.
I also added a rubber band to the Z tower rods to remove some rattle. It wast a bit long so I stretched if from one lower pivot to the upper pivot.

In Cura I use 3.5mm at 20mm/s. Since I have ordered a new E3D to replace this MG hotend, I'm not going to worry about calibrating the retraction yet..
As for updates, I printed two 1515 mini Kossel top frame pieces. I printed them at 15 x 15mm for the extrusion cutout (no extra) and it fit perfectly both times, so this one is as well-calibrated as my original.

Not trying to be argumentative, but if there is a need for 1/32, I don't quite see it.*
(* actually, implementing a closed loop stepper system with an encoder might be a good reason for it, but I don't think putting a $150 encoder on a $20 stepper is likely on these inexpensive 3D printers.)
For me, 1/32 stepping is "quieter" than 1/16 which is much quieter than 1/8 stepping. Some

Hi Jay - I've followed your build over on GGroups as well, as I am interested in this build. The lack of editing there bothers me, too.
Wanted to ask, though - can you tell me or direct me to an explanation of why the X5 prompts you to sell an existing RAMPS setup? I know the X5 is cheaper, but beyond that I am just curious about it, no other agenda.
Well, it was more of a sta

My 16 tooth pulleys arrived from tridprinting.com (they are fast shippers) so I started assembly on the two towers with the mounted motors.
This image shows the Kossel to the mini Kossel I have with Nylon sliders (7" build plate).
I'm still not sure I'll keep the vertical beams so tall, but we'll see.

Ok, I watched the video. Keep in mind this is a delta, to move in the "z" direction all 3 motors have to move the same amount. Are you able to jog in the X and Y directions? That part looks tiny compared to your build surface, maybe try something bigger to see the motion. Care to attach your configuration.h

I have been logging my build at the Google Groups site, but the lack of ability to edit a post has me looking for an alternate site.
Background:
I have build 2 mini Kossels. The first was cmpletely stock and follwed the directions. The second was to see how cheaply I could build one. It uses printed PLA sliders which I upgraded to Nylon with Brian H. sent me a set to try. I'm not looking to scal
