I'm building my delta currently. It uses a 12v power supply for cartridge heater and motors etc. The bed is 500w 110v AC mains powered. Currently for testing I have the printer using two outlets, one to power the bed, the other the main power supply. Are there any merits to this as opposed to jumping off the 110 line powering the DC power supply anyway? Currently Alternative Note that is aby clearlynotstefan - Safety & Best Practices
Basically a heavily modified version of this. It turns out my first print was a little skewed causing some magnets to be slightly closer together than they were at the carriages. Now I'm getting much less (but still some) effector tilt. I'm still not getting a good first layer on bigger prints.by clearlynotstefan - Duet
I'd wait till someone who's actually knowledgeable on this chimes in, but if you want to rule it out completely try unplugging your switches and see if it resolves. I believe having the 3v (red) wire improperly wired closes heater circuits or something like that. Someone awesome will show up and solve everything shortly, thats just my best guess to try in the meantime.by clearlynotstefan - Duet
Check your endstop connections are correct. I am far from an expert, but I seem to recall incorrectly wired endstops being implicated in problems like this.by clearlynotstefan - Duet
JESUS IT WAS THE EFFECTOR. I printed a godawful version of it (skipped steps, nozzle dragging etc, eventually it stabilized around layer 8, pushed the ball studs straight through the bottom few layers, figuring this is as good as it'll get). Calibrated 6 factor, returned 0.08 or so first shot, babystepped to a solid z0 and fired up another effector, first layer stuck like glue with no nozzle dragby clearlynotstefan - Duet
DC, I'll add my next question here because its relevant. Clearly I'm having difficulty calibrating a printer with a great frame but something off effector wise. I have a bullseye level coming tomorrow to see if I can detect effector tilt, I'm running on the assumption that effector tilt is whats causing my calibration issues due to the nozzle offset. I'm confident my rods are solid (magrogs by Haby clearlynotstefan - Duet

If I can't get it swapped out, how about replacing the stepper driver chip itself? It looks like I could snip the old chip out and potentially solder the remaining feet onto the new chip, or desolder the chip entirely and through-hole solder in a replacement. The chips themselves look pretty cheap! (edit: I'm not home with my board, I can't recall if the chips are even through-hole soldered or noby clearlynotstefan - Duet
As you've no doubt realized from my many posts I'm the proud owner of a new duet wifi thats powering my custom delta. Yesterday I realized I had some skipped steps so I checked the recommended motor current for my motors and was surprised to find I was only running them at 50% recommended current. So I changed my config to reflect that, as well as some other tweaks, like setting microstepping (myby clearlynotstefan - Duet
Thanks for going through that monster post! One point of clarification, the slanted print did actually have G29 compensation on it. It stuck like glue and was uniformly squished getting my hopes up! Then it moved over .2mm or so per layer. It makes sense, if g29 disregards H parameters it can't possibly be a usable option on machines with effector tilt, all it does is compensate for an actually lby clearlynotstefan - Duet
Hey helpful people I'm posting one thread with all of my questions on the various software calibration options we have, because frankly I don't really get them and their relationships to each other yet. This is a rambling post of many questions, any help on any of them would be appreciated. Background: 2040 based delta with aluminum vertexes. I am very confident that my horizontals and verticalby clearlynotstefan - Duet
Quotedc42 The disadvantages that I see of extending the print bed outside the base triangle are: - The printer is less easy to transport, because you can't put it on its side on a non-padded surface (but other things like wheeled carriages may prevent you from putting it on its side anyway) - It makes the printer harder to enclose - For a given rod length, the closer together the towers are, theby clearlynotstefan - Delta Machines
Another basic question for you helpful people! I'm (re)building my delta now, and I have a question about the positioning of the bed relative to the size of the horizontal rods. I'm using V-slot 2040 if that matters. Currently my bed is a 300mm circle and my horizontals are quite long, long enough that I can easily fit the bed inside the triangle without resting on the edges. I've seen many deltaby clearlynotstefan - Delta Machines
Absolutely positive, additionally my diagonal rods are measured accurately, and I get fairly consistent deviations on 6 factor G30s. I tore it down to rebuild tomorrow, once I get it back together nice and strong I'm gonna try DC42's suggestion of 4 factor G30, there's also a chance just pulling everything apart and reassembling clears something up haha.by clearlynotstefan - Delta Machines
Thanks. It was a tough question to phrase so I totally understand the confusion. Appreciate your help, I'll let you know how it works out when I get this straightened out.by clearlynotstefan - Duet
It doesn't appear I have any tower offsets in my 665 M665 R229.929 L360.25 B150 H591 ; set delta radius, diagonal rod length, printable radius and homed height I do run 6 factor G30s on startup though, so if tower offsets are calibrated in those 6 factors, its possible that's a source of them.by clearlynotstefan - Delta Machines
I mean I appreciate your concern, but you're answering basic questions that I know the answers to. I understand delta motion fine, but obviously I'm encountering a problem with the axis alignment. The question of whether the effector moves like a + or an x when viewing from a perspective with 2 towers on the bottom is an entirely fair one, after all if you view from a different angle, you'd get tby clearlynotstefan - Duet
Any idea why my X and Y aren't perpendicular?by clearlynotstefan - Delta Machines
What would make my axes not perpendicular excluding steps per mm? Also what's the jog carriage g code again? To make it disregard delta and just spin one motor? I'd like to recheck those stepsby clearlynotstefan - Duet
So I've been tinkering and setting up my delta on duet wifi. Spent the last few days working on effector tilt, printing new parts on my other printer and generally making it more solid before I start printing.

Whoops sorry for a silly question. Turns out I overwrote my SD card with the wrong file simultaneous to my wire extending, had R1000s instead of 4700. They'll be of course many more silly questions for you generous people.

How would I wire it with 4 wires? I'd try that if it'd help!by clearlynotstefan - Duet
I cut all of my effector side cables (fan, hotend, thermistor, ir board connector) and extended them with 20awg for everything but the hotend (16awg). No problems on fan, haven't tested IR, but I noticed I'm getting MUCH higher readings at room temp on e0 thermistor. Would a significantly longer cable (think 2m) introduce noise or resistance or cause signal dieoff sufficient to skew my numbers? Cby clearlynotstefan - Duet

Hey friends, hoping you could help me get my .85 functioning. I had some difficulty with Bossac and all that noise, I finally was able to update my .85 and duet to the appropriate DC48 fork for my custom delta.

Problem solved. I left out one detail, because I never set my Y stepper so high I was concerned with how it crept up and swapped it with my E2 stepper which isn't in use. Turns out the E2 stepper (formerly Y stepper) didn't get seated all the way down. Turns out if you don't have a stepper motor connected to E2 (even if you're not using it) g29 will pretend to level but not actually level!by clearlynotstefan - Firmware - Marlin
This is a serious riddle. I use g28 then g29 before each print and have for a long time with great results, I usually manually level the bed every so often just the bottom of my prints isn't too skewed. Today I was printing without problem, did literally nothing. Jumped a step and realized my Y stepper was getting a little too much juice and rolled the pot down a bit.
