Marlin wont let you set E0 to anything but 0,0. The best solution I found was to leave both nozzles at 0,0 in Marlin then use the slicer to set the offsets of the nozzle. I didn't try PrusaSlicer but in Cura you can set the Extruder nozzle offset in Machine Settings, Extruder 1 or Extruder 2 tab.by thehankinator - Delta Machines

Are you able to command the print head to move (with Pronterface, LCD or something) around the bed without any problems? I'd start with the Z at like 0.2 and slowly move it around.by thehankinator - Delta Machines
IMO the small parts will never be exactly right and will always be a nuisance when you need to work on the printer or cause dimensional inaccuracies in the frame . I'd choose to reprint them to the correct size.by thehankinator - Delta Machines
I'm glad you got it sorted out!by thehankinator - Delta Machines
The only functional difference I can see between your config and mine is that I disabled DELTA_HOME_TO_SAFE_ZONE which shouldn't make a difference. Have you tried an older release of Marlin? Since this is an Arduino I'd try 1.1.9 Have you tried swapping around the stepper drivers around? Swap what connector the motors are connected (and endstops to match) to on the RAMPS? Do you have another Ardby thehankinator - Delta Machines
I have an Anycubic Kossel Linear Plus, nothing jumps out at me from this config as being wrong. Some things to think about though: 1) You said you are using an Arduino MEGA + RAMPS yet MOTHERBOARD is defined to BOARD_TRIGORILLA_14. Probably fine since I think Trigorilla is based on RAMPS but maybe there are differences. 2) I had to enable ENDSTOP_NOISE_THRESHOLD to prevent noise from erroneouslyby thehankinator - Delta Machines

The explanation I read said that if the magnets are on the effector, the strongest part of the magnetic field will be at a fixed angle. So as the effector moves the the build area the magnet field will likely not be aligned with the rod. When the magnet is in the rod, the magnet is always aligned to the rod giving it's full strength to hold the rod to the ball at any angle. It seems like the magnby thehankinator - Delta Machines
If you were planning on the same approach as me (ball on the arm with magnet in the effector/carriage), I wouldn't go down that path... If I were to attempt it again, I would do the reverse (magnet in the arm with ball on the effector/carriage). Like this . I think the top left picture might be dc42's printer so I think there is more credibility to this approach than some rando on Thingiverse. Tby thehankinator - Delta Machines
In addition to the binding, they also had play in the rod end causing backlash. After doing some research I decided to try the magnetic rods like this design. It was a total disaster. The magnets are no where near strong enough to hold the rods in place. Simply homing the effector caused the whole thing to fall apart. Only after this point did I stumbled upon a forum post talking about how this aby thehankinator - Delta Machines
The first time I made rods I also used a single jig that was bolted to the frame of the 2020 frame. I used the typical rod ends like these. They came out perfect, looked identical as far as I could tell. Unfortunately I kept having issues with the print head hitting the bed, calibration was always a dumpster fire no matter what approach I took. After a month or two of troubleshooting I noticed thby thehankinator - Delta Machines
QuoteMils24 I will have a go at the escher3D calculator and try the manual approach again. What setting are missing in Marlin that you mentioned? Could you give me a little more detail on that? I selected the "standard" Marlin firmware type. Definitely use the preset button for positions in Pronterface or Octoprint. Be conservative with the Z value on these points, I have damaged nozzles and scrby thehankinator - Delta Machines
I have a similar printer and used many versions of Marlin. For me ABL seems to make things worse than better and I just keep it off. I have no proof but I suspect: 1) ABL has been broken for Delta machines(or more?) since 1.1.9. There are other tickets open for ABL but this is one I am following 2) Autocalibrate isn't very good. I've messed with this a lot and I came to the conclusion that itby thehankinator - Delta Machines
Typically dimensional inaccuracies on a delta are due to an incorrect value for the diagonal rod length. Try using a formula like this: ActualSize/ExpectedSize*CurrentRodLength=NewRodLength Using the example you gave, I would try decreasing your rode length by about 1.3%. Side note: I have the same printer. AnyCubic didn't cut the rods to the same length (they are supposed to be exactly the sby thehankinator - Delta Machines
Do you have the probe offset entered into Marlin? Since your probe is off to the side a bit, have you checked for any effector tilt?by thehankinator - Delta Machines
I am working on a delta with a Chimera+ hotend installed. Each nozzle is +-10mm on the X axis from the center of the effector. Marlin disallows setting the offset of E0 to anything other than 0,0. So I have resorted to setting offsets in Marlin to 0,0 for both nozzles but then setting the nozzle offsets in Cura. If I understand this correctly, this means Marlin will have no idea where the activeby thehankinator - Delta Machines
I had worse luck with Prusa Edition although I may have misconfigured it, I didn't spend more than couple hours with it. I decided to keep using Cura and I eventually solved the problem! The issue was the Combing feature, it was set to "All". This feature disables retraction under certain conditions. Well for me it would travel over the perimeter area without retracting and the filament would oozby thehankinator - Slic3r
Thanks for taking a look at my problem. Since this is a delta, would that mean that all 3 stepper motors are binding? Do you have any advice for tracking down the cause of binding? Sorry, I'm pretty inexperienced with 3D printing.by thehankinator - Slic3r
I am having a problem printing Benchy with Slic3r. It's kind of like a layer shift except that it's more like the model got scaled larger on 3 sides. I don't have this particular issue with Cura so I think it's a configuration problem but maybe it's a hardware issue? I've checked everything I can think of to verify that it's tight, including the belts. I've attached my Slic3r config. Has anyone rby thehankinator - Slic3r
