Built my dual extruder delta machine recently and had a couple successful print and a few bad ones. While trying to calibrate it as perfectly as I can, I noticed that the "parallel" arms of my delta are not really parallel. The distance of the joints at effector is around 0.5 - 1mm wider than the joints at the carriages. Is this something that absolutely needs to be corrected? The problem is that I see no good way of fine tuning the distances, the way the diagonal rods are mounted means the only "adjustment" I can make is to add washers, which is not really adjustable at all... Also as I only need less than 1mm increase of the width, which means I may only be able to add washer at one of the mounts, making it unsymmetrical, which I'm not sure may cause even bigger problem or not. https://reprap.org/forum/read.php?178,769429,769429#msg-769429 Sat, 17 Oct 2026 01:42:04 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?178,769429,769659#msg-769659 https://reprap.org/forum/read.php?178,769429,769659#msg-769659
Then I had a calliper set to correct width and use it as a guide to limit the mount movement before securing all the screws again.]]> mianwo Delta Machines Mon, 22 May 2017 20:37:27 -0400 https://reprap.org/forum/read.php?178,769429,769537#msg-769537 https://reprap.org/forum/read.php?178,769429,769537#msg-769537 scottybfg Delta Machines Mon, 22 May 2017 07:23:03 -0400 https://reprap.org/forum/read.php?178,769429,769509#msg-769509 https://reprap.org/forum/read.php?178,769429,769509#msg-769509 spinor Delta Machines Mon, 22 May 2017 05:27:22 -0400 https://reprap.org/forum/read.php?178,769429,769450#msg-769450 https://reprap.org/forum/read.php?178,769429,769450#msg-769450 dc42 Delta Machines Mon, 22 May 2017 01:27:25 -0400 https://reprap.org/forum/read.php?178,769429,769447#msg-769447 https://reprap.org/forum/read.php?178,769429,769447#msg-769447
Post your design and someone may be able to determine a solution.]]> etfrench Delta Machines Mon, 22 May 2017 01:16:24 -0400 https://reprap.org/forum/read.php?178,769429,769429#msg-769429 https://reprap.org/forum/read.php?178,769429,769429#msg-769429
