The following document outlines a temporary manual method.\n\nAlignment consists of Vertical offset and Horizontal components. The horizontal component is the distance between the same point on the two ink cartridges in the printers y axis. The vertical component is the distance between the two ink cartridges in the printers x axis. Due to manufacturing tolerances each Argentum will have a slightly different alignment values. In the ARC software the vertical component is called \"Distance between cartridges\" and the horizontal component is called \"Misalignment of the print heads on cartridges\" which will be referred to as \"Misalignment\" in this tutorial.\n\nThese variables can be accessed in the alignment menu under Printer > Processing Options\n\nWhen misalignment occurs a trace will appear thinner than it should be, or if the misalignment is bad enough the trace/line will not appear at all.\n\nThe easiest way we've found to figure out what \"Misalignment\" and \"Distance between cartridges\" should be for your printer is to print concentric squares of varying width aligned in the axis of the printer. By looking at which lines appear you can see how good your alignment is.\n\nThis is the test image we use to do this (NOTE: click on the image to get to the proper resolution version, then save that image for use):\n[block:image]\n{\n  \"images\": [\n    {\n      \"image\": [\n        \"https://files.readme.io/10LJE2kNQw6SuoOGOQWH_400px-Alignment2.png\",\n        \"400px-Alignment2.png\",\n        \"400\",\n        \"400\",\n        \"#eaeaea\",\n        \"\"\n      ]\n    }\n  ]\n}\n[/block]\nGo ahead and download this test image.\n\nThe ARC software comes pre-loaded with default alignment values of 726 for \"Distance between cartridges\" and 0 for \"Misalignment\". We've found these values to work well on a variety of printers. We've found that at most the alignment will be within +- 10 in each axis. For the alignment I used a \"distance to move between lines\" value of 63.\n\nIn order to change your alignment values just change \"Distance between cartridges\" and \"Misalignment\" in the printer options menu and click save. Because the alignment is written into the print file stored on the SD card you'll need to re-process the test image each time you change your alignment.\n\nThe basic procedure for calculating alignment is to vary the vertical and horizontal alignment while observing which lines are visible in the test print. As an example I'll show the alignment procedure while varying \"Distance between cartridges\" only. Only changing one variable will make the misalignment more obvious.\n\nI started by setting \"Distance between cartridges\" set to 10. After printing the test image this was the result:\n[block:image]\n{\n  \"images\": [\n    {\n      \"image\": [\n        \"https://files.readme.io/wEv2OVi1Sbi1lB10dxLb_400px-10.jpg\",\n        \"400px-10.jpg\",\n        \"400\",\n        \"411\",\n        \"#757536\",\n        \"\"\n      ]\n    }\n  ]\n}\n[/block]\nAs you can see the first 3 lines are visible but the 4th was patchy. Because we know that the \"Distance between cartridges\" should be around 0 its most likely that we need to decrease the offset. After changing \"Distance between cartridges\" to 7 this was the result:\n[block:image]\n{\n  \"images\": [\n    {\n      \"image\": [\n        \"https://files.readme.io/2hxEA4bvTeKjljgAaTio_400px-7.jpg\",\n        \"400px-7.jpg\",\n        \"400\",\n        \"411\",\n        \"#a3ae43\",\n        \"\"\n      ]\n    }\n  ]\n}\n[/block]\nNow we can see a few more lines so we're getting closer. After changing \"Distance between cartridges\" to 4 this was the result:\n[block:image]\n{\n  \"images\": [\n    {\n      \"image\": [\n        \"https://files.readme.io/mLMcWkqHTLGsi9ModFnW_400px-4.jpg\",\n        \"400px-4.jpg\",\n        \"400\",\n        \"400\",\n        \"#838d3f\",\n        \"\"\n      ]\n    }\n  ]\n}\n[/block]\nLooks pretty perfect right? Yes! but we're not quite finished yet. There will be a few alignment values for which you can see all the lines. In order to really dial in our \"Distance between cartridges\" we're going to get the range for which our print is perfect and take the midpoint. Decreasing by 3 again to make \"Distance between cartridges\" 1 we get this:\n[block:image]\n{\n  \"images\": [\n    {\n      \"image\": [\n        \"https://files.readme.io/c5MsRDHQTxSElL4z6aU3_400px-11.jpg\",\n        \"400px-11.jpg\",\n        \"400\",\n        \"406\",\n        \"#a1aa3e\",\n        \"\"\n      ]\n    }\n  ]\n}\n[/block]\nThis looks pretty much the same as when \"Distance between cartridges\" was 4. Lets decrease it again to -2 and see what happens:\n[block:image]\n{\n  \"images\": [\n    {\n      \"image\": [\n        \"https://files.readme.io/U5Yy806NRdOh8mLLAnwb_400px--2.png\",\n        \"400px--2.png\",\n        \"400\",\n        \"395\",\n        \"#615728\",\n        \"\"\n      ]\n    }\n  ]\n}\n[/block]\nNow we're getting worse again. This looks similar to 7 but perhaps slightly better. So we know that the best value for \"Distance between cartridges\" is between 4 and 1. The median would be 2.5 but we can only have integers so since 7 was better we'll pick the higher number 3. This is our optimal value for alignment of \"Distance between cartridges\".\n\nI'd recommend starting with \"Distance between cartridges\" set to 10 and \"Misalignment\" set to 736. Then decrease them by 3 each print until you find the bounds of your alignment. To speed things up you can vary \"Distance between cartridges\" and \"Misalignment\" at the same time.","excerpt":"","slug":"alignment","type":"basic","title":"Alignment"}
