Has anyone else had issues printing the effector (non-magnetic one, of course) hosted on Thingiverse? This is the one titled "Z_Probe_Effector_J_Head_Non_Magentic". I just had someone off 3DHubs try to print it, but it's failed on what I think are the loops for the bolt which holds on the fan. When I import the model into Solidworks it says there are over 2,000 errors with faces, which it fails tby pugzor - Delta Machines
Gentlemen! I think I'm back in the game. I've had a little break and now have funds to attempt it again. Can I ask, have there been any major design changes? Andy, has the thingiverse still got files compatible with most of the kit I received? I think I need to get new carriages, rod carriers, effector assembly, filament feed assembly and the smaller top pieces to get things running (the end caby pugzor - Delta Machines
Well, I don't have a working CP3 yet, but earlier last year I backed The Micro on Kickstarter. I was part of the December tier and filled out my survey a few days ago. I know it's probably still a couple of months away but when I get it I will more than likely be able to print replacement parts for my CP3. It's only got a small build area but I think it should be enough to do pretty much everythiby pugzor - Delta Machines
Well gents, it appears I'm actually out of the game for a while due to my own stupidity. I was going to go to a hackerspace meeting tonight as there was a regular with a lot of experience building deltas. I live a fair way away from work so catch the train in, leaving my car at the train station during the day. Out in the sun. Yeah... ends up hot cars and thermoplastics don't mix too well.

I've noticed that my carriages have a bit of play in them, but I'm not sure what's the cause. I'm having troubles autocalibrating again and I think this might be one of the reasons but I'm not sure. The adjuster screws are done up to a nice tension so there's no play, but I noticed that when you move one of the opposite tower carriages it's noticable. For example, there's a bit of a wobble in towby pugzor - Delta Machines
QuoteAndyCart Yes the hot ends I supply are 0.4mm. The bearings were designed into the extruder for a reason! If I were you I would swap the washers. It's simple and cheap and is another thing you don't need to worry about Something I'll do when I get a chance, but it shouldn't be affecting the machine's ability at this point in time.

Given the level of questions I've been asking, I think that's a legitimate question haha, but yes I do have that tightened down (just opened it up for the pic). I understand your point of view around the hobbed bolt, but I might have things worked a bit differently. You see, I haven't tightened the nut that holds the hobbed bolt on. There's about 0.5-1.0 mm of play and I've used a second nut toby pugzor - Delta Machines
But isn't the bolt locked to the gear since the head of the bolt fits into the big gear wheel? The bolt is moving, it just doesn't seem to be "grabbing" to the filament.by pugzor - Delta Machines
Okay, so, I got an autocalibration to happen again. Took around 20 minutes. Next issue! Lol. So, my printy doesn't seem to want to put out filament consistently. I can see pretty easily that my hobbed bolt has basically no traction on the filament whatsoever. Given the attached picture, what can I do to fix this?by pugzor - Delta Machines
I think I've passed the point where I've now spent more time messing with firm/software than it took to acquire all the parts and build the actual machine, haha. Pretty sure I've spent enough that I could have organised personal delivery of a unit from you too, Andy! Really want to get it up and running so I can make custom Christmas tree ornaments. Yeah, I know how to party.by pugzor - Delta Machines
Yeah, I think you've said that before Andy. I've adjusted it but I think it'd be the only thing I haven't checked again within the last couple of days. I might actually double check that all of the end stops are quite firmly glued in place still. My assumption is that if one of them isn't firm, it could be moving just enough to mess with calibration? If memory serves I had an autocal accuracyby pugzor - Delta Machines
Bed is rock solid. Spring tension is awesome.by pugzor - Delta Machines
Gents, is anyone able to give me a check list of things that may be causing autocalibration to be unable to finish? I've checked quite a lot since replacing my carriages again (3rd set without laying down plastic yet lol) but it is refusing to finish calibration. My belts are tight, there's no twist in the carriages, everything seems to be secure... I'm at a loss and kind of frustrated.by pugzor - Delta Machines
Yeah, I double checked, all my M5's were tight but that side of the top bracket was still affected by tension on the M5. No idea why. Probably just me doing something retarded, as always. Anyway, I tried to start printing a square as per the fine tuning suggestions. I hit print and then realized I hadn't put glue down on the bed, so I hit pause, the extruder heated up, then I returned it to homeby pugzor - Delta Machines
Yeah, sure do. Probably just my incompetence then. I just added a third M3 30mm screw to the top (probably 5mm from the edge, in line with print lines where the stem meets the cherries in your logo) and it has much less flex now. Doesn't look pretty now that I've got screws in the top. Running autocal now after it took 4 hours last night before I turned it off. Seems to be running through the prby pugzor - Delta Machines
Very cool Andy, the red looks awesome too by the way! Can I make a suggestion? I'm not sure if this is something caused by my own incompetence or if it's a suggestion for legitimate improvement... but maybe an extra screw to secure the top components together? I know there's a couple already but a third on the outer edge (in the corner) might help. I only came across this because I was curiousby pugzor - Delta Machines
Ha Sebastien! Where there is a will, there is a way, right? You're using a paperclip, I'm using mains core... Andy, I'm insanely confident that lack of tension isn't the issue. It's quite difficult to get my rods into the cups... I think there's around 5cm extra length between the rods and the Spectra/spring length. Now that I've rotated the effector 120° so that the fan is facing the LCD, it'sby pugzor - Delta Machines
I found some mains copper wire which is 1.1mm thick, put it in a nice tight loop. I think the problem with the wire I was using was that after a few twists it loses its strength. Hoping that even though I'm using copper, if it doesn't twist and lose its strength, it should be fine. Certainly seems better than the old stuff but we'll see. I think I'm going to step back from it for a week or so tby pugzor - Delta Machines
LOL, well that didn't last long. The tin wire I had holding my springs in broke on two of the carriages! Totally unexpected, just sudden flying rods! Pretty sure I had way too much play, as in my loop was too big. I know how I'll correct it next time. Hopefully this time tomorrow I'll be printing!!!!!!!!!!!!!!!!!!!!1111one Thanks so much for your help Andy.by pugzor - Delta Machines
Ends up I'm an idiot. If your delta looks like mine does, make sure you've got the effector probe wired/config'd correctly. Mine was config'd as triggered when it should have been open.by pugzor - Firmware - mainstream and related support
*facepalm* I can't believe... I set the Zmin to false because by design you were using the NC config. So, it's autocalibrating as we speak. Endstops only took 11 iterations. It's having fun doing the other calibration though. Seems to be zeroing in on it... RadiusC is -0.03 now.by pugzor - Delta Machines
Another video, this time of the funky movements my delta does instead of actually calibrating.by pugzor - Firmware - mainstream and related support
I get you... It'll hit on the extrusion gears if I don't. Didn't figure that one out haha. Thanks for the warning before it made contact! Surprised it hadn't already. Anyway, here's a video of my failing autocalibrations. I just completely reloaded a fresh copy of Marlin straight from GitHub, copying only my configuration.h file over. No joy.by pugzor - Delta Machines

Hey party people, I recently finished building a Cherry Pi III. I've uploaded Marlin successfully and can get it to respond to a lot of commands, but I'm having some issues with autocalibration. My woes so far have been chronicled in AndyCarter's Cherry Pi III thread (which I unfortunately highjacked). Take a gander here: I've been able to do manual adjustment of the endstops but when I go toby pugzor - Firmware - mainstream and related support
Yeah, I totally spoke too soon haha! Did the endstop adjustments quite fine. Wasn't a bad exercise actually! I think I'll actually enjoy fine tuning the print quality. My issue came with the autocalibration, again. For some reason it still believes the endstops are outside of 3mm of each other? I'm confident the probe isn't being triggered too. From someone who hasn't even seen a 3D printer worby pugzor - Delta Machines
Thanks so much for that Andy! Hopefully there won't be too many snags now... At least it'll be mostly for print quality and that'll be fine tuning. I'll post up a first print soon!by pugzor - Delta Machines
Okay, so autocalibration is actually doing something now! Woo! Problem is now that it's saying my endstops aren't within 3mm of each other, which I'm thinking is a damn lie. The tower heights were awesomely close to being equal length. Is there anything else that may be giving this error? Also, what parameter might I have to adjust given that I added ~50mm to my build height? Is it possible thaby pugzor - Delta Machines
