Challenge accepted. Stay tuned for my version of an effector. Started it today.by clearlynotstefan - General
To verify, the current board with 3 inputs will use 3 discs and trigger upon first contact with any of them right? I've got some ideas that I really think would work well.by clearlynotstefan - General
I've got a few thoughts on how to do it vertically. Maybe I'll throw one together.by clearlynotstefan - General
It seems you are using your frustration at the difficult delta calibration process to disregard the million other ways RRF is superior to marlin. Keep your duet. Use this new Piezo approach, it's absurdly good, and enjoy the many other benefits of RRF, even things as basic as line segmentation.by clearlynotstefan - General
Hey how much can I take off of the peizo before I start facing consequences? This system where I have to disassemble the entire effector to pull out my Bowden tube is unworkable. I had a thermal jam today, took me like 45 minutes to pull it out and put it back together lol. If I can take a little more out of the Piezo disk I could get a thin tweezer from the top to push down on the bowden releaseby clearlynotstefan - General
Interesting, I've been probing at f700. You found this too quick? I was thinking a little speed should give a more definitive probe impact, I look forward to seeing how 300 works.by clearlynotstefan - General
Just checking, if I'm holding the board so it's vertical with the pins facing down, which is pot1 and which is pot 2?! Also, why do you favor digital as opposed to analog on the dirty and what g code specifies which?by clearlynotstefan - General
Where are you located? I've got some PEI sitting around.by clearlynotstefan - General
Hey all, back from vacation and I've finally got my fancy Piezo setup running. Duet wifi, lykle's effector (printed SLA), M's board version with 2 pots. So far I've gotten great results just fiddling with the sensitivity randomly on a glass bed, but am getting mixed results on PEI. Either the pei is a little squishy, or my actual sheet of PEI is just shot, I have a backup sheet that I'm gluing onby clearlynotstefan - General
I'm considering a corexy bed leveling concept and I'm curious if my idea is feasible. I'd like to auto level the bed for real, not via compensation. Rather than cantilever the bed, I'd like the 4 corners to ride on 4 lead screws. I'll use 4 piezo sensors at the corners, or one atop the hotend. Ideally I'd have a script or macro that moves the hot end to each corner, and raises that corner till thby clearlynotstefan - Duet
Is the carriage crooked in the third picture? Does one rod start closer to the effector than the other? Everything needs to be perfectly symmetric.by clearlynotstefan - Delta Machines
Any chance of getting that setup as openscad customizable or thingiverse customizer or anything like that? I'm drooling to try this but my rod spacing is unique....by clearlynotstefan - General
QuoteLykle Hi ClearlynotStafan, What is the distance between the balls of your magentic arms. Not the length of the arms, but on the effector. I have a 48 mm one and a 64 mm one ready. Once DJ gives the go-ahead I will post them on the Zesty Thingiverse page and DJDemonD will probably put them up on his as well. Let me know. Currently tweaking the design to make sure all the screws needed aby clearlynotstefan - General
I'm on a delta, with Haydn's arms indeed! I have my FSR board (john something or other) and my IR board which is my main probe currently. I'd be happy to get my hands on a board made for this purpose though.by clearlynotstefan - General
How far along is this project? I'm currently using an IR probe on a delta, I've messed with FSR in the past. I miss the 0 offset of FSR but the repeatability wasn't there for me. Is this far along that I should print one and give it a shot? Parts list?by clearlynotstefan - General
Another vote for painting the pei and using the ir sensor. I was skeptical too, even set up an fsr system first, now I'm 100% ir on spray painted pei.by clearlynotstefan - Duet
I think ya'll are overthinking the part cooling thing a bit. A part at 190-250 getting hit with air at 50 is still cooling. As for cooling the heat-break, I hadn't considered that, but of all the enclosed printers running stock hot-ends, we don't see enough posts to suspect heat-creep issues. I'm 80% of the way enclosing my delta at the moment too, let you know how it goes if I finish first.by clearlynotstefan - Delta Machines
Ah nebbs, good call. My calibration has turned out great but I do rely on H parameters in the firmware to offset some effector tilt. The good news is I know what's causing it and have placed an order to fix it. Didn't consider how that'd impact scaling issues. I had assumed the h parameters during calibration would price that tilt into the equation and prevent it from impacting scale.by clearlynotstefan - Delta Machines
Yesterday I managed to print a 295mm filled circle with absolutely perfect layer height, so I considered my calibration efforts complete and successful. Today I printed a 30mm cube which measured to about 30.5mm how might I go calibrating that out. It's within the range of over extrusion error, but my e steps are calibrated well, I just need to bring xy dimensions in a percent or two.by clearlynotstefan - Delta Machines
Sorted it, up is up haha. Let the record show I just printed a 295mm circle with a perfect first layer, no mesh leveling and only s4 factor calibration. After endless struggles the big delta prints!by clearlynotstefan - Duet
So I'm able to technically print across all of my 300mm bed, but I'm noticing in a particular spot my first layer is a little too squished. I'm using H parameters in my bed.g with the IR probe. If I wanted to manually tinker with the H parameter, which way should I be going on the probe point near the squished spot? Do I make H bigger or smaller to tell it to raise the nozzle a bit more.by clearlynotstefan - Duet
LOL I figured it out. I had accidentally unchecked relative extrusion distances in S3d lol. Everytime it'd retract it'd come halfway out of the bowden tube!by clearlynotstefan - Duet
Doh! Alright I'll give that a shot. Still, I'm confident firmware retraction isn't set up properly in either my s3d settings or my config, as others were successfully using earlier firmwares with it.by clearlynotstefan - Duet
Yes, just updated my firmware yesterday.by clearlynotstefan - Duet
Hey all, I'm trying to set up retraction with my Duet wifi (latest firmware) and Simplify3D. David, I believe you're an S3D user yourself, could you share your S3D setup and your M20x configs so I can see how you've got this going for firmware retraction? Currently my retractions shoot back 5mm at a solid speed, then fail to unretract, causing no filament to come out till its halfway through thby clearlynotstefan - Duet
As one of the delta masters round these parts, what do you think of my plan: attach a spare stepper to the uppers, set it to reflect Z height and basically just reel the extruder up as the print goes. Bowden would only need to be long enough to reach the outer edges from the middle.by clearlynotstefan - Delta Machines
Bah that's way less fun. More fun to have a matter of seconds to perform fine motor function things right next to 240 metal object before your hotend smashes through your bed!by clearlynotstefan - Delta Machines
Followed your instructions with that fuse, duet operational once more. I've now blown a via, and popped a fuse, my duet is turning into a frankenstein-duet with these wires patching things up haha Thanks for all the great support as always!by clearlynotstefan - Duet
Interesting! Didn't think that through. Until DC drops the new version that has it, you could use gcode macros to do the same thing I believe. adjust your Z then click a macro that runs G92 Z(your first layer height). That'd work for the time being I think.by clearlynotstefan - Duet
