[email protected] Evan - did you ever get the CNC mill portion working? As best I can tell the Azteeg X3pro isn't compatible with GRBL or TinyG. Bob Bob, I have not actually gotten to the mill part, but I still have a reserved spot on my tool plate. If I do any time soon I'll post my results. I'm not sure why X3 pro wouldn't work with GRBL, but it may take a good bit of pin definingby Tired2 - Extruded Aluminum Frames
Thanks for the info. The main thing I've been meaning to try is the decay mode pin, but I've yet to give it a shot. Even if it does quiet them down, it may have other detrimental effects that I don't like (poor current control). $35 per driver is a lot different than $10 per driver, but it will do a better job I'm sure.

Thanks for the links, I'll look more at them when I get some more time. I've seen a few of them before. I am running my motors at 24V. The board I'm using can handle up to about 30 or 35V or so before the regs get mad. The drives can handle 42V, but there is no need.... The torque is reduced, but at the speeds I'm running I get most of the torque I want. It is unclear to me in the 8825 databy Tired2 - Extruded Aluminum Frames
A2, The motors are: stp-mtrh-23079 Be sure to read the first few posts... I'm only running them at 2.5A, so I'm leaving a lot of torque on the table. The speeds seem good, much faster than the extruder can keep up with, so that is fine for me. Check out the youtube videos if you have not: They also make a hell of a noise on 24v that is pretty annoying, but I think most of that is the driby Tired2 - Extruded Aluminum Frames
That is an excellent way to measure it, but what I don't know is how critical the orifice land length is, and what an appropriate value would be. All I have to go off currently is that some forum user decided the stock E3D one was too long and needed to be shorter.by Tired2 - Extruded Aluminum Frames
QuoteA2 Tks found more about the nozzle orifice land length in this thread: He put the hot end in the freezer to help extract the filament intact from the nozzle orifice. I linked it above as well, hope you caught that. I did not need to freeze it to get the length out of it. Just heat it up with pressure on it, let it cool with pressure on the filament (manually pushing)... once it cools doby Tired2 - Extruded Aluminum Frames
Hey! Thanks for joining in here for some fun. This thread usually leads my youtube series by a bit since editing takes so much time. This is the real deal, the videos are for people in the future, not as I get it worked out.

Quotecnc dick Yeah that's really pretty fast not to say that you can't do it but probably something you don't want to do on every print. That would be something to use on hollow single wall thickness and still get a good print but as a rule I usually print with ABS which is a little slower and I stay between 50 and 80 mm a second it can go much faster but print quality suffers not from machine woby Tired2 - Extruded Aluminum Frames
QuoteA2 Congrats on making it into the top 10 finalist of the Misumi "Build Brag Win" Contest Thanks! I lost though, second place, maybe third. The guy who won built a small electric scooter.

CNC_Dick, Do you have plans for that extruder? CAD or anything? I've failed one print tonight so far.... I thought it was the E3D jamming, but I was able to hand-push some filament through right after with no problem... The extruder had buckling inside it, though that is not the problem, it happens after the hobbed bolt, which I can tell is getting good traction. I agree they should be largby Tired2 - Extruded Aluminum Frames

Hey, thanks for keeping up with my thread. That extruder is a nice piece of work! I think I've narrowed my problem to one or two things... hopefully I'll know which it is soon enough. So, I've read that the 0.4 nozzle is not ideal for PLA. I don't fully believe this. I went ahead and ordered a 0.6mm and hoped it would solve my problems. Things went better but still jammed up eventually. Soby Tired2 - Extruded Aluminum Frames
They are a bit confusing. You can see a problem in the top photo, but it is gone in the bottom photo. The right side of the 'hour glass' shape is the transition from heat sink to heat break tube I think. Here is a drawing: I ordered my whole setup from E3D (Really filastruder here in the US) all as one kit, so unless they mis-kitted something it should all be good.

Oh, I actually did make some progress. Misumi's new contest is giving away a $200 VISA gift card to the winner of a "what you built with the First150 promo" thing. I tidied up my printer's wiring a bit and cleaned off my desk. Below is my entry photo. You'll notice I got the Extruder raised up enough to mount the spools. For now they are just on a peice of All-thread rod with a T-Nut on theby Tired2 - Extruded Aluminum Frames
So, the jamming persists, and I don't have that much time right now. The tube did not help, the extra space in there just let the filament accordion more as friction in the hot end goes up until it just can't push anymore without the filament buckling in the extruder or the extruder slipping. I did take some filament impressions of the hot end, and re-did the "hot" tightening process with a bitby Tired2 - Extruded Aluminum Frames
Quotegmh39 Did you try loosening the tension on the filament? (Hobbed bolt). The filament should not be getting that distorted. I don't run a Bowden, just assuming the filament tension is similar to a non-bowden extruder. The New baby has arrived! Just a few days early... hence my lack of progress. The new tube should be at work waiting on me, I'll get it tomorrow and hopefully carve out a fby Tired2 - Extruded Aluminum Frames
So, I'm having jamming problems with my bowden tube. It seems that if I clamp the hobbed bolt setup down tight enough, it makes the filament too oblong to slide through the 4mm OD 2mm ID PTFE tube. It slides smooth right off the spool, but then is tight after the length of filament is extruded. I have a plan though... I looked up the standard equivalent, and it seems like good news.

Here are some pics, as requested. Do you have any pics of your new machine coming together? Did you make a thread on it? I'm still working out details and quality/temperature/flow issues, but I'm pretty happy so far. You can see on Yoda's ears that the flow died out a bit on me, I'm not sure what that is about yet. I think maybe my extruder gears are a bit out of round so the velocity of theby Tired2 - Extruded Aluminum Frames

I got my new borosilicate glass. It was about $33 from McMaster Carr, 10x10"x3/16". I have a few new cubes to show of the last few hours, but they are hourglassing a bit and curling up. I'm taking CNC_Dick's advice on adding a "part cooling" fan. I have it rigged up, but I got held up on wiring when I realized I don't have the pinout to enable new fan outputs and such, so I needed to handle tby Tired2 - Extruded Aluminum Frames
CNC_Dick, Thanks, I'll try that out. I had trouble finding out if a fan on the part was ideal or not. Should the bed turn off after the first few layers? I broke the glass I was using, which I figured might happen. I have some 3/16" x 10 x 10" borosilicate glass on the way, hopefully it will arrive tomorrow.

Thanksby Tired2 - Extruded Aluminum Frames
This is a good feeling.... This was the very first print (and only to date, I'm shutting down for the night). I had to heat the bed with a heat gun to get it to stick, and slow it down to 60mm/sec to get the extruder to not jam (possibly just a temperature issue or something). Anyway, back to making videos.

I had to go back into 'car' mode this weekend, fixing up the project car, oil changes, etc, so not much printer work got done. I could have probably printed by now, but I realized when I went to mount my bed plate that the CAD model I used for the template that I used to drill and counterbore the plexi was wrong. Somehow in a re-draw of the base plate I got the bearing block holes off by 90 degby Tired2 - Extruded Aluminum Frames
I fabbed up my new extruder mount bar. The distance from the extruder's exit and the first place it was contained axially was about 2 inches or so, and I think that was too much for it and it buckled and got jammed up. After that I realized I was gripping it too tight in the bearing/hobbed bolt interface, which caused it to turn oval and add a lot more friction in the bowden tube.

Lookin good. I did a quick video review of my extruder, which is a wades geared. I don't have much experience with it yet though. My video needs edited still, but it will be up in a few days.

Gordie, When deciding the belt, just be sure you take into account that probably the smallest pulley you can get with a GT2 will still not limit your max speed... so basically, the smaller the better for max torque, unless at some point it limits your max speed.
