Yeah, that would definitely work or a nut on both sides of the top piece tightened toward one another.Would I use a die to thread the plastic tube? Any idea what the OD is on this tube? If I could just get it to print a few times, I could print out a better clamp system I found on Thingiverse. This is definitely a chicken and egg situation. I'll keep trying to figure it out.

I've been battling with the Bowden tube for about 8 hours now. It continues to pop out when I try to print. Unfortunately, on one attempt where I left the room for 5 min, the Bowden tube pulled so far out that it pulled the connector on the temperature regulator out of its socket. The hot end got so hot that it partially melted the Peek. It's been oozing more and more around the brass, too. I pushed the brass back into the Peek as it cooled, and it stayed there (for now.) I've tried using nylon ties to hold the Bowden tube. I've tried roughing up the surface and wrapping coil winding wire around it below the clamp & blue horseshoe. I've gotten so desperate that I tried to drill a small hole in the top of the peek to put a set screw into a notch in the tube to hold it in place. Didn't work, just mangled it. Nothing has worked, and the various parts are in poor condition now from all of my attempts at fixing the Bowden problem. Even the tube itself is scarred up from me using pliers over and over to shove it through to the peek. I've made a mess of it while trying to fix this issue. I so wish they had pre-assembled/tested units 9 days ago when I ordered. I would have bought one. Ok, unless anyone has another idea I can try, it looks like I need to order a new print assembly and Bowden tube after all this. Anyone know do I go about doing that? The store doesn't list very much in the way of replacement parts.

Blue clip is on. What's the horse clamp? I don't think I have one of those. EDIT: Tried putting some nylon wire ties around the clamp and blue horseshoe clip, but it didn't help. The tube still pulls out of the print head. Looking through forum for other things to try, atm.

Yeah, I figured the scale number would have to be the conversion rate from inches to mm, but once I started trying to print, I'm having other much worse issues. After hours of trying, I still don't have a single print. My Bowden tube just won't stay seated in the print head. Instead of the filament feeding through the head, the feed is just pushing the tube up. Only a tiny trickle of plastic comes out while tube just pushes itself right out of the head. Help!! I've obviously done something terribly wrong. Any ideas?

Ok *red face* I just figured out that the power switch was off. It apparently still powers the electronics from USB when the power is off, but the heater won't heat.

Here's what's happening: I loaded a file in Cura, prepare printed, then printed. The print head heated to 220, then started moving as if it was printing. The filament wasn't anywhere near the head, so no plastic came out. I figured this out, and cancelled the print. The print head immediately started cooling. So, I move the filament up to the head by turning the wheel manually. Then, I tell it to print again. Same as before, the dialog changed to the temperature display. It still shows 220 for the target temp, but my print head is not heating up. The display on my UltiController shows it sitting at 37 degrees and not moving. Nothing else is happening. Cura is just stuck at the printing dialog with a horizontal pink area showing a steady temperature over time. If the print head has already been heated up for a print that was cancelled, Cura seems to lose track or lose control of the heat settings after that point.

Finished assembly. Unit powered up fine. Windows 7 found and installed Arduino mega256 drivers when I plugged it into USB. Installed Cura. Upgraded Marlin. Passed all the tests. Now, wondering how I get Cura to read my STL files in inches instead of mm. When I load my files which are dimensioned accurately in Sketchup, they load as tiny miniature versions of themselves. I'm assuming it's an Inch vs MM thing. What can I do to tell Cura to use inches?

Thanks again SG. I did what you said and got it in. Crazy, but seems ok for now.

Having another issue at the moment. The Z axel rods are not lining up at all after going through the platform. It's off by a lot so torquing on the bar would likely damage wood somewhere. Here is a photo: Any ideas?

Wow, thanks for all of the tips!! Some of these, I've figured out the hard way already. LOL Others were surprisingly not a problem. My kit came with a nicely labeled spacer kit for the motors which worked perfectly so that I got maybe 5 or so threads into the motors. Should be good. I'm partway through assembly now. I have found that a huge number of the wooden parts don't quite fit together (probably swelling?), so I've spent literally hours having to carefully widen openings with a file. For a couple, I had to pull out my Dremel with a small circumference sanding tip to widen openings. Right now, I'm having to widen all of the openings for the stacks of pieces which surround the large Z axis linear bearings while assembling the print bed. I also accidentally broke a wire off of one of the leaf switches and ruined the switch while trying to solder it back on. Had to make a run to Radio Shack to buy another leaf switch, then bore out the mounting holes for M3. That added a little delay. I'm about 16 actual work hours into assembly now and hoping to finish up today. I'm sure anyone new to this can relate to the fact that my biggest fear right now is that I'll turn it on after all this and nothing will work. LOL The worst thing is, they just announced that they are selling assembled and tested units now. Doh!! I would definitely have bought one of those, if it had been available a week ago when I ordered. *sigh* Timing is everything. Thanks again snowy.

Clearing a workspace for assembly tomorrow. Thank you Anita for your help! Anyone have any assembly tips?
